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

revised: 29-Feb-2012

This document indicates how paleocurrent directions 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.

Description Symbol Feature Classes & Attributes Comment
paleocurrent-fluvial map symbol Fabric_point
  • RockType=[variable]
  • LineType="fluvial paleocurrent"
  • LnSubType="unspecified"
  • Trend="70"
 If these data include trend and plunge and bedding data in the same record, the true paleocurrent vector should be calculated.
