Abstract

Mapping of outcrop geology on Leonora 1:100 000 map sheet in the Eastern Goldfields, Western Australia, as part of the National Geoscience Mapping Accord (NGMA). Briefly, mapping consists of geological boundaries/units, faults, fractures, folds, veins, dykes, joints, linears, marker beds, trends, structural measurements, and mineral deposits.

Lineage

Geological themes in northeastern three-quarters of area were generated from field observations and stereoscopic interpretation of aerial photographs (1:25 000 colour). In the southwestern quarter, geological themes were generated from stereoscopic interpretation of aerial photographs (1: 80 000 B/W). Geophysical themes were generated from magnetic data (90-m cell size grids derived from airborne magnetic surveys). Mines/mineral deposit locations and information are sourced from Department of Minerals and Energy, Perth, and from Sons of Gwalia Ltd, modified by field and air-photo observations. Topographic themes were derived from orthophoto maps prepared by Kevron in 1997-98, supplemented by data from Australian Survey and Land Information Group (AUSLIG) and Department of Lands and Surveys, Perth (DOLA). Some amendments to the topographic data have been made by the authors. Lineage of topographic data before receipt from AUSLIG and DOLA is uncertain. Maps were compiled from unrectified photo-overlays on to enlarged orthophotomaps prepared by AGSO from Kevron 1997-98 data. All visible topographic features (individual trees, vegetation patterns, roads, fences, drainage, lake boundaries) were used for spatial control of the geological data. Compilations were digitally captured by scanning and vectorising procedures. Point data with database origins were located by the non-differential GPS method. Some detail may have been generalised, repositioned, or omitted from the primary data for cartographic purposes.
