This example shows placer districts as solid polygons classified according to COMMODITIE (eg. Au, PGE, Sn, etc.).  The background geology is classified according to PERIOD with only those units containing Mesozoic or younger aged rocks showing.

The following files were used to draw this view:
  \circum\shp\geol5m\rox5mpe.asx
  \circum\shp\base\w_mask.asx
  \circum\shp\base\hydro.asx
  \circum\shp\depos\placerco.asx
