Document conventions

Version 1.0 was produced April 1997, following a development project to unify1:10 000 scale and 1:50 000 scale map symbols (CS/R&D/7).

Version 2.0 was produced February 1999, following geological updates, and inclusion of linestyles and area ornaments.

1 Introduction

1.1 This document was put together from information created using MicroStationfrom Bentley Systems and CellManager from Axiom International . It wasalso designed to accompany three digital libraries, which may be released atsome future time.

Standard Geological symbols

1.2 The geological symbols are described in section 2.1.3 The BGS standard length for an average symbol is 3mm at 1:25 000 scale and all

smaller scale maps, and 4mm for 1:10 000.

The Reference names are an abbreviated form of their description, many aregrouped together in their geological classification with a common prefix asfollows;

ALV Alluvial depositsBRK BrickearthGFL Glaciofluvial depositsGLA Glaciolacustrine depositsGL Glacial depositsIGL Interglacial depositsLAC Lacustrine depositsMA Marine depositsRM Raised marine depositsRS Rock symbolsRT River terrace depositsS Structural symbolsSG Sand and gravel
