Cross sections are constructed based upon the interpretations of theauthors made from geologic mapping, and available geophysical(regional gravity and aeromagnetic surveys), and subsurface (drillhole)data. Cross sections should be used as an aid to understanding thegeneral geologic framework of the map area, and not be the solesource of information for use in locating or designing wells, buildings,roads, or other man-made structures.

Recognized in drillholes and named for depositsunderlying the broad inner valley floodplain near the community of Las Padillas in southwest Albuquerque(Connell et al., 1998b). Unconformably overlies upper Santa Fe Group deposits and is commonly gravellyat the base. Probably interfingers with stream alluvium (QHa and Qay). Deposit surface (top) comprises themodern surface of aggradation for the Rio Grande. Surficial deposits (< 6 ft [2 m] thick) are divided into amodern river channel, and four textural subunits based on interpretations of soil series described and mappedby Hacker (1977). Approximately 50-80 ft (15-24 m) thick.

Menaul Formation (upper to upper-middle Pleistocene) — Poorly consolidated deposits of yellowish-brown (10YR) pebble gravel and pebbly sand derived from the ancestral Rio Grande. Named by Lambert(1968) for exposures along Menaul Blvd. Gravel clasts are dominated by rounded quartzite pebbles that aregenerally smaller in size than pebbles and cobbles in the Edith Formation (Qre). Discontinuously (probablylensoidal) exposed along the eastern escarpment of the inner valley of the Rio Grande. The basal contact isapproximately 85-118 ft (26-36 m) above the top of the Las Padillas Formation (Qrp, Rio Grande floodplain),and is unconformably overlain by younger stream alluvium (Qay). Thickness is generally less than 10 ft (3 m).
Edith Formation (middle Pleistocene) — Poorly to moderately consolidated, locally cemented deposits ofpale-brown to yellowish-brown (10YR) gravel, sand and sandy clay derived from the ancestral Rio Grande.Named by Lambert (1968) for exposures along Edith Boulevard and the eastern escarpment of the inner valleyof the Rio Grande. Gravel clasts contain abundant rounded quartzite and volcanic rocks with minor granite,metamorphic sandstone, and very rare (commonly welded) Bandelier Tuff. Comprises an upward-fining sequencecontaining a basal, quartzite-rich cobble gravel that grades upsection into silty sand. Unconformably overliesupper Santa Fe Group deposits, and is unconformably overlain by eastern-margin piedmont alluvium (Qpm)and younger stream alluvium (Qay). Unit Qay buries the Edith Formation south of the Jaral Canyon arroyo.To the north, unit Qay is inset against the Edith Formation. Basal contact is approximately 40-80 ft (12-24 m)above the top of the Las Padillas Formation (Qrp, Rio Grande floodplain), and maybe warped down to thesouthwest by up to 45 ft (14 m) across the Alameda strand of the East Heights fault zone. Gravel pits (withindaf) yielded late to middle Pleistocene Rancholabrean fossils (Lambert, 1968; Lucas et al., 1988). Moderatelydeveloped soils on overlying eastern-margin piedmont alluvium (Qpm) suggest a middle Pleistocene age forunit. Variable thickness, ranging from 10-40 ft (3 to 12 m).
Stream-valley and eastern-margin piedmont alluviumDivided into stream-valley alluvium and eastern-margin piedmont alluvium. Stream-alluvium typically containpoorly to well sorted, poorly to well stratified, clast- and matrix-supported deposits associated with modernand late Pleistocene entrenched arroyos across the map area. Eastern-margin piedmont alluvium containsgenerally poorly sorted, poorly stratified, clast- and matrix-supported deposits having angular to subangularclasts of granitic, metamorphic, sandstone, and minor limestone derived from the western and northern slopesof the Sandia Mountains and eastern basin margin. .

Inset against eastern-margin piedmontalluvium (Qpm). Distal margin is truncated at the eastern escarpment of the inner valley of the Rio Grande.Surface is slightly dissected and possesses weakly developed soils with Stage II carbonate morphology. Locallyincludes undivided stream alluvium (QHa) in narrow arroyos. Underlies entrenched stream valleys on thepiedmont slope. These arroyo valley deposits grade west into older alluvial fans that mark the position of anolder valley border. These alluvial fans may locally contain hydrocollapsible soils. Locally subdivided into older(Qay1, on adjacent Bernalillo Quadrangle, Connell, 1998) and younger (Qay2) deposits on the basis of insetrelationships. Deposits along the northwestern margin of map area consist of sandy alluvium with scatteredgravel lenses derived from the Arroyo de las Calabacillas drainage. This deposit contains clasts of red granite,chert, and basalt derived from the western margin of the basin.Correlative to geomorphic surface Q8 of Connell(1995, 1996). Variable thickness, ranging up to 20 ft (6 m).
Middle eastern-margin piedmont alluvium, undivided (upper to middle Pleistocene) — Poorly tomoderately consolidated deposits of very pale-brown to strong-brown and light-gray (7.5-10YR) sand and siltyto clayey sand, and gravel.

A geologic map displays information on the distribution, nature, orientationand age relationships of rock and deposits and the occurrence ofstructural features. Geologic and fault contacts are irregular surfacesthat form boundaries between different types or ages of units. Datadepicted on this geologic quadrangle map are based on reconnaissancefield geologic mapping, compilation of published and unpublishedwork, and photogeologic interpretation. Locations of contacts are notsurveyed, but are plotted by interpretation of the position of a givencontact onto a topographic base map; therefore, the accuracy of contactlocations depends on the scale of mapping and the interpretation ofthe geologist(s). Lambert (1968) produced a geologic map (scale1:48,000) of the region prior to significant ground disturbance. Portionsof Lambert’s map are incorporated where surface disturbance issignificant. The geology of areas of extensive ground disturbance havebeen evaluated using aerial photography (1935, 1951, 1973, and1996 vintages). Any enlargement of this map could causemisunderstanding in the detail of mapping and may result in erroneousinterpretations. Site-specific conditions should be verified by detailedsurface mapping or subsurface exploration. Topographic and culturalchanges associated with recent development may not be shown.Subdivision of the Las Padillas Formation was made using geologicinterpretations of (shallow) soil survey data published by the SoilConservation Service (Hacker, 1977).

Older subunit (middle Pleistocene) — Moderately consolidated deposits of light- to strong-brown (7.5YR)and very pale-brown to light-gray (7.5-10YR), poorly to moderately stratified and sorted, sand clayey sandand gravel. Unconformably overlies the Edith Formation (Qre). Subdued bar-and-swale constructionaltopography is locally preserved on broad weakly dissected interfluves. Dissected deposit surface (top)commonly exhibits erosional ridge-and-ravine topography. Moderately well developed soils with StageIII+ carbonate morphology and many moderately thick clay films. Geomorphic surface Q6 of Connell(1995, 1996).
Older eastern-margin piedmont alluvium (middle to lower Pleistocene) — Consolidated deposits ofyellowish-brown (10YR), poorly sorted and stratified, gravel and sand with minor, thin silty-clay interbeds.Gravel clasts are predominantly subangular granite and schist with minor subrounded limestone. Granite clastsare commonly pitted, and schist clasts are typically weathered and split. Variable thickness, ranging to at least60 ft (18 m).
Upper Santa Fe GroupAxial-fluvial deposits of the ancestral Rio Grande, undivided (lower Pleistocene to Pliocene) —Consolidated and locally cemented, very pale-brown to yellowish-brown (10YR) sandstone and conglomeratedeposited by the ancestral Rio Grande. Gravel clasts are predominantly rounded quartzite and volcanic rockswith minor granite and basalt. Dominantly sandstone with interbedded pebbly to cobbly conglomerate, butgenerally coarsens upsection with cobble conglomerate beds common near the top. Interfingers with upperSanta Fe Group eastern basin-margin piedmont deposits (QTsp) to the east. May be correlative with axial-stream deposits of the Sierra Ladrones Formation (Machette, 1978) described along the southern margin ofthe Albuquerque Basin. High hydraulic conductivity where saturated. Subdivided into an upper, pumiceousunit (QTsau) on map. Subdivided into upper (QTsa2) and lower (QTsa1) silty sandstone marker beds on crosssections. Base not exposed but interpreted to be at least 2,000 ft (610 m) thick in drillholes. . .
Upper pumice-bearing axial-fluvial deposits (lower Pleistocene) — Very pale-brown to yellowish-brown (10YR), pumiceous sand and pebbly to cobbly sand deposits by the ancestral Rio Grande. Gravelclasts are predominantly rounded pumice, quartzite and volcanic rocks, with minor chert, granite, andmetamorphic rocks. Pumice clasts are derived from the ca. 1.61 Ma lower Bandelier Tuff (Lambert, 1968;W.C. McIntosh, 1997, personal communication). Medium-to coarse-grained, euhedral, bipyramidal quartzgrains are locally abundant. Bedding is subhorizontal, and commonly cross stratified. Minor silty sandbeds are discontinuous and range in color from light brown to grayish green. Approximately 210 ft (65m) thick at Tijeras Arroyo (Lucas et al., 1993).
Upper sandy mudstone marker bed (Pliocene) — Cross section only. Muddy sandstone and sandymudstone recognized by laterally correlative zones of relatively low resistivity (high electrical conductivity)on borehole geophysical logs. Approximately 150-200 ft (45-60 m) thick and about 100 ft (30 m) abovethe lower marker bed (QTsa1). .
Lower sandy mudstone marker bed (Pliocene) — Cross section only. Muddy sandstone and sandymudstone recognized by laterally correlative zones of relatively low resistivity (high electrical conductivity)on borehole geophysical logs. Approximately 100-150 ft (32-45 m) thick.
Piedmont deposits (lower Pleistocene to Miocene) — Subhorizontally stratified to slightly east-tilted, reddish-brown to yellowish-brown and very pale-brown (7.5-10YR) conglomerate, gravelly sandstone, and sandstonewith subordinate siltstone and rare mudstone. Conglomerate clasts are predominantly composed of subangularto subrounded granite with subordinate metamorphic rocks, and minor subrounded limestone. May be correlativewith piedmont-slope and alluvial fan deposits of the Sierra Ladrones Formation (Machette, 1978) exposed atthe southern margin of the Albuquerque Basin. Interfingers with axial-fluvial deposits (QTsa) to the west.Moderate to low estimated hydraulic conductivity. Thickness is variable and estimated to range from 2,000-7,000 ft (610-2,135 m).
Arroyo Ojito Formation, Loma Barbon Member (lower Pleistocene to upper Miocene) — Wellconsolidated, weakly to moderately cemented, yellowish-brown to yellowish-red and reddish-brown (5-10YR),fine-grained silty sandstone with interbedded mudstone and scattered, lensoidal, weakly to well cemented,conglomeratic sandstone interbeds. Deposits are tentatively correlated to the Loma Barbon Member on thebasis of reddish-brown color and correlation to Lambert’s (1968) middle red formation. Shown as querieddeposit (Sections 25 and 36, T12N, R3E) because of restricted access to existing exposures. The Loma BarbonMember interfingers with fluvial deposits of the ancestral Rio Grande (QTsa) on adjacent quadrangles (Connell,1998; Connell et al., 1998b). Estimated thickness is over 1,400 ft (>425 m). .
Arroyo Ojito Formation, Atrisco Member (Pliocene) — Cross section only. Moderately to well consolidated,locally cemented succession of yellowish-brown to yellowish-red (2.5-10YR), fine-grained silty sandstone andmudstone (Allen et al., 1998). Named for deposits beneath the Town of Atrisco Grant (Connell et al., 1998a),where it is recognized in the subsurface by a laterally extensive interval of high electrical conductivity (lowelectrical resistivity) on borehole geophysical logs (Connell et al., 1998a, b). Borehole geophysical logs indicatethat the upper contact is conformable and gradational with the overlying fluvial deposits (QTsa), and marksthe base of an upward-coarsening megasequence that culminates in dominantly gravelly sand of the axial-fluvial deposits of the upper Santa Fe Group (QTsa and QTsau). Fine-grained and difficult to determineprovenance; however, the lateral continuity of unit, as interpreted from geophysical correlations (Connell etal., 1998a, b), suggest that this unit may be correlative to the Arroyo Ojito Formation, exposed west of themap area. Thus, this member is provisionally assigned to the Arroyo Ojito Formation. Subsurface data indicatesthat unit is approximately 280-330 ft (85-100 m) thick (Connell et al., 1998a).
Lower fluvial deposits (Pliocene to upper Miocene) — Cross section only. Fine-to coarse-grained sandstonewith interbedded compact clay and rare scattered pebbly sandstone interbeds. Regional borehole geophysicallog correlations (Connell et al., 1998a,b) suggests that unit pinches out to the east into eastern basin-marginpiedmont deposits of the upper Santa Fe Group (QTsp). May be correlative to piedmont-slope and alluvialfan deposits of the Sierra Ladrones Formation (Machette, 1978) exposed at the southern margin of theAlbuquerque Basin. May include undivided western basin-margin deposits of the Arroyo Ojito Formation. Basenot exposed, but regional thickness is estimated to be greater than 2,000 ft (610 m) thick in drillholes.
Paleogene and Cretaceous Systems
Lower Tertiary and Cretaceous sedimentary rocks, undivided (Paleogene-Cretaceous) — Cross sectiononly. Undivided lower Tertiary (probably Galisteo Formation and Lozinsky’s (1994) “Unit of Isleta No. 2”)and Cretaceous deposits. .
MESOZOIC ERATHEMJurassic and Triassic Systems
Entrada Formation — An inlier of yellowish-brown, moderately sorted, fine-medium-grained sandstone. Poorlyexposed on the hangingwall of the Rincon fault (Section 28, T12N, R4E). Stratigraphic position is ambiguous,but unit is tentatively correlated to the Entrada Formation based on sandy texture and color.
Chinle Group, undivided — Reddish-brown mudstone and yellowish-brown sandstone, probably correlativeto the Petrified Forest Formation (Van Hart, in press). Unit occurs as highly faulted inliers between the Jaral,Rincon, and Sandia faults.
PROTEROZOIC ERATHEMMesoproterozoic igneous rocks
Pegmatite dike — Dikes, pods and lenses composed of pegmatite, aplite and quartz formed during emplacementof the Sandia granite at 1,400 Ma (Kelley and Northrop, 1975 and Brookins, 1982). .
Sandia granite — Mainly megacrystic biotite monzogranite to granodiorite with K-feldspar megacrysts, upto several cm long. Intrudes the metamorphic rocks (Xqs) of Rincon Ridge. Approximately 1,400 Ma (Brookins,1982).
Paleoproterozoic metamorphic rocks

COMMENTS TO MAP USERS
Construction and hydraulic data table for selected wells in the Alameda quadrangle and vicinity. Data interpreted and modified from Bexfield (1998),Connell and Heynekamp (1998), Jackson et al. (1998), Johnson et al. (1996), John Shomaker and Associates (1990), Groundwater ManagementIncorporated (1988 a,b,c,d), and public-domain well- log repor ts from the New Mexico Office of the State Engineer. Abbreviations include: multiplescreened intervals (M), transmissivity (T), hydraulic conductivity (K), depth below land surface (bls), elevation above mean sea level (amsl), upper piezometer(u), and no data/not determined (nd). Asterisk (*) indicates depth of constructed well, exclusive of pilot-hole depth (i.e., minimum depth of well). Doubleasterisk (**) indicates stratigraphic interpretation for entire borehole depth.
