Abstract
A GIS data set created from a map, first published by BMR in 1983, that depicts the distribution of metamorphic facies in Australia. The original map was compiled between 1972 and 1983 by T.G. Vallance, G.W. DAddario, A.J. Stewart, J.E. Mitchell, J.F. Stirzaker, and A.S.Mikolajczak using data supplied by BMR, State and Territory Geological Surveys, Universities and the Geological Society of Australia. As a digital data set the attributes have been revised to allow relational analysis of the data within. Two formats of GIS data are provided: ArcView shape files and Mapinfo TAB files.

Lineage
This data was produced by scanning and vectorising the published 1 : 5 000 000 Metamorphic Map of Australia (Bureau of Mineral Resources, Geology and Geophysics, Australia, 1983). This original digital version (1995) contained several ArcInfo coverages: geological boundaries and coastline, major faults and trends. In 1996, these individual coverages were re-projected to comply with the current national dataset projections and were combined into one dataset in which the linework and the polygons were fully attributed as per the original 1983 edition. The attributes of the dataset encompass all the map surrounds but have been subsequently revised and tailored to facilitate better use in the GIS environment. As such the major attribute of the dataset is the "rock_class" which can be used to distinguish metamorphic and igneous rocks. For metamorphic rocks the items fac_series and metagrade apply and for igneous the ig_class, era and lith_desc apply.
