Apr 13, 2018 · Look into the using the SVG fill symbol layer type in QGIS, to use a repeating SVG pattern of your choice. The USGS lithologic patterns have already been converted to SVG and are available from the University of Otago here with a description on how to edit them.

Apr 20, 2015 · An implementation of many of the USGS FGDC Geological Map Symbolization for use by QGIS. Also included is a set of QGIS .qml files representing the geochronostratigraphic colour scheme proposed by the Commission for the Geological Map of the World.

Patterns with attributable color are in: /SED sedimentary /IGM igneous and metamorphic. Patterns with fixed color are in: /SED_fixedcolor sedimentary /IGM_fixedcolor igneous and metamorphic. There is also a QGIS workspace that shows all the patterns (and …

Jan 15, 2022 · This is yet another (1, 2, 3, 4, 5) FGDC fill geology symbols library for QGIS 3.x. All fill symbols tile seamlessly and most are standardised in a 50x50 pixels area. The colour of all symbols can be changed in QGIS as is the stroke width of many symbols.

The USGS have published their complete symbol list together with how each symbol is constructed and a full description of the USGS patterns and symbols can be found here. I have downloaded one symbol set from Steve Revets site and have modified some of these to remove bounding borders and allowed the patterns to be coloured.
