SAMPLE_ID:  80MW0013

DATE: 6/13/2002

Sample: 80MW0013 - Dolostone


A marly dolostone, sample 80MW0013 contains dolomite, plagioclase, magnesite, and calcite veins. Texturally, this rock is characterized by a matrix of microcrystalline material with zones showing an almost glass-like swirl microstructure. Calcite veins are up to 0.3 cm thick, and in some places are offset by minor faults/deformation bands. This rock is interpreted as a lithified fault gouge material.
