SUMMARY:

Capsule descriptions are as follows:

TAR10032-101.5: strongly phyllic (sericite-quartz?-chlorite-carbonate-pyrite-rutile-relict Kspar?)

altered sub-volcanic or hypabyssal rock possibly originally about hornblende dacite in composition

(not granodiorite), initially composed of plagioclase and amphibole phenocrysts with accessory

ilmenite and apatite microphenocrysts in an aphanitic groundmass. It is cut by narrow calcite-chlorite-minor sphalerite-quartz veins, and contains relict xenoliths with minor pyrrhotite,

chalcopyrite and sphalerite.

TAR10035-75.75: appears to represent strong/intense phyllic (quartz-clay?/sericite/muscovite-Fe

carbonate-pyrite-minor Kspar?-rutile) altered possible breccia composed of highly tectonized

(sheared) clasts of granodiorite (quartz, relict sericite-carbonate altered feldspar and mafic minerals)in comminuted matrix of the same plus hydrothermal quartz, sericite, pyrite or local pyrrhotite-trace

chalcopyrite, possible carbonate and apatite, trace zircon (?). It is possible that the pyrrhotite-trace

chalcopyrite represents a separate phase of mineralization (in the clasts, similar to that seen in

xenoliths in the previous sample), different from the main pyrite (trace galena inclusions, trace

sphalerite) which is concentrated in the matrix.

Detailed petrographic descriptions and photomicrographs are appended (on CD). If you have any

questions regarding the petrography, please do not hesitate to contact me.

TAR10032-101.5: STRONG PHYLLIC (SERICITE-QUARTZ-CHLORITE-CARBONATE-PYRITE-RUTILE-KSPAR?) ALTERED HORNBLENDE DACITE PORPHYRY (?)

Described as showing fine-grained texture and crystals (predominantly plagioclase 30%,

biotite 5% and hornblende (?) 3%, possibly dacite or altered granodiorite); hand specimen shows pale

greenish grey, finely porphyritic sub-volcanic/hypabyssal rock composed of small (

TAR10035-75.75: BRECCIA: SHEARED GRANODIORITE CLASTS, COMMINUTED MATRIX,

ALTERED TO QUARTZ-SERICITE-CARBONATE-PYRITE-KSPAR?-RUTILE-APATITEDescribed as granodiorite batholith with coarse feldspar and quartz phenocrysts, possible

sericite and argillic alteration (?); hand specimen shows what may be pale grey-buff coloured breccia

(?) composed of strongly phyllic/argillic or locally silicic altered (or quartz-rich) clasts (?) up to 2 cm

diameter in finer-grained, siliceous-pyritic matrix. Some clasts contain significant, likely secondary,Kspar associated with pyritic sulfides. The rock shows local trace magnetism, slow reaction to cold

dilute HCl, and minor yellow stain for K-feldspar in the etched offcut. Modal mineralogy in polishedthin section is approximately:

Quartz (mainly secondary) 30%

Sericite, muscovite 30%

Clay?/sericite 15%Carbonate (mainly dolomite, ankerite?) 10%

Pyrite, trace galena inclusions, rare sphalerite 7-8%

K-feldspar (secondary?) ~5%Rutile 1%

Pyrrhotite/trace chalcopyrite 1%

Apatite, trace zircon (?)

TAR10032-101.5: Intensely phyllic altered porphyry composed of sericite-carbonate altered relict plagioclase (PL) and

chlorite-carbonate altered mafic (M, likely originally hornblende?) phenocrysts plus apatite (ap) microphenocrysts in

groundmass of sericite (ser), quartz (qz) and local pyrite (py, opaque). Transmitted plane light, field of view 3.0 mm.

TAR10032-101.5R: Mafic relics containing traces of rutile (ru) which also occurs as tabular pseudomorphs after ilmenite

(?) within cubic pyrite (py) crystals, cut by narrow vein of calcite-chlorite-local sphalerite (sl, with minute chalcopyrite

inclusions)-quartz (qz). Reflected light, uncrossed polars, field of view 2.25 mm wide.

TAR10035-75.75: Sheared, deformed clasts of quartz (qz), Kspar (Kf), former plagioclase altered to clay?/sericite

(cl?/ser) or mafics altered to muscovite (ms), Fe-carbonate (cb) and rutile (minute opaques) in breccia or brecciated

granodiorite (?). Transmitted light, crossed polars, field of view 3.0 mm wide.

TAR10035-75.75R: Pyrrhotite (po) and trace chalcopyrite (cp) associated with strong sericite (ser)-Fe carbonate (cb)

alteration of clast (possibly after relict Kspar?). Adjacent matrix is mainly sericite altered, comminuted material.

Reflected light, uncrossed polars, field of view 2.25 mm wide.

TAR10035-75.75R2: Cubic pyrite (py) associated with matrix (mainly sericite) between clasts that are mostly quartz (qz).

The pyrite rarely contains trace inclusions of galena (gn). Reflected light, uncrossed polars, field of view 2.25 mm wide.
