Geological rock types polygons (1:100,000)

The data contains primary geological data, namely outcropping/sub-cropping geological rock units.This layer has been superseded by the Seamless Geology layer - SG_GEOLOGICAL_UNIT_50KThe dataset is part of the geological mapping dataset, which includes datasets representing geological rock units and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, metamorphism, and placer deposits.The data have been collected by the Geological Survey of Victoria. Data have typically been captured in projects covering 1:100,000 mapsheets, and have typically been recorded in the field by hand at 1:25,000 then prepared for hard copy printing at 1:50,000.本数据集包含基础地质数据，即露头/隐露头地质岩石单元。该图层已被无缝地质图层（Seamless Geology layer）- SG_GEOLOGICAL_UNIT_50K 取代。本数据集隶属于地质填图数据集范畴，涵盖地质岩石单元与边界、构造线、杂线与杂点、杂多边形、变质作用及砂矿床相关数据。该数据由维多利亚地质调查局（Geological Survey of Victoria）采集。数据通常依托覆盖1:100000比例尺图幅的项目开展采集工作，一般以1:25000比例尺在野外手工记录，随后按1:50000比例尺制作为纸质印刷件。
