NMBGMR Draft Geologic Data Model - v. 1.0.3
SYMBOLOGY: Igneous Fabric Point Features

revised: 29-Feb-2012

This document indicates how igneous fabrics recorded at a point portrayed on a geologic map should be coded in the data model. See the NMBGMR Symbol set (3.7 Mb PDF) for details on how our standard symbology is constructed).
