Geological rock types polygons (1:100,000)

The data contains primary geological data, namely outcropping/sub-cropping geological rock units.\n\nThis layer has been superseded by the Seamless Geology layer - SG_GEOLOGICAL_UNIT_50K\n\nThe dataset is part of the geological mapping dataset, which includes datasets representing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.\n\nThe 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.

数据包含原始地质数据，即出露/隐伏地质岩性单元（outcropping/sub-cropping geological rock units）。

该图层已被无缝地质图层（Seamless Geology layer）SG_GEOLOGICAL_UNIT_50K取代。

该数据集是地质填图数据集的一部分，后者包含代表地质岩性单元及边界、构造线、杂项线与点、杂项多边形、变质作用（metamorphism）及砂矿床（placer deposits）的数据集。

数据由维多利亚地质调查局（Geological Survey of Victoria）收集。数据通常在覆盖1:100000比例尺图幅的项目中采集，且通常在野外以1:25000比例尺手工记录，随后制备用于1:50000比例尺的纸质印刷。
