Flaser gneiss A dynamically metamorphosed rock in which lenses or layers of original or relatively unaltered granular materials are surrounded by a matrix of highly sheared and crushed material, giving the appearance of a crude flow structure

This notebook shows the objects related to display: Decor: One element from a legend — describes how to display a Rock.; Legend: A set of Decors — describes how to display a set of Rocks or a Striplog. In the more intensely deformed southern gneiss unit, local pods of protomylonitic flaser gneiss grade into mylonites containing asymmetric K-spar augen set in a dynamically recrystallized matrix. U-Pb analyses of four fractions plus an air-abraded split of one fraction form a normal linear discordance pattern with an upper intercept of 820 2007-1-13 · Flaser gneiss, fine grained gneiss and biotite gneiss.

2003-11-7 · Although granite, which became the flaser gneiss, was probably intruded into the amphibolite, its contact today is a shear zone. Garnetiferous, biotite flaser gneiss (Fig. 1) near water level at the northwest corner of the Cornel 1 bridge is composed of coarse lenses of zoned feldspar in a …

Erdogan ve Gungor (1992), noticeced that Cover schist which has rarely consist some mafic metavolcanics passing through Mesozoic aged Layered Quartzofeldspathic Augen Gneiss and Flaser Gneiss (Proterozoic Y) at surface, covers 8 % of this area. Leucocratic to mesocratic, mesoscopically-layered coarse-grained quartzofeldspathic biotite gneiss contains prominent polycrystalline quartz-feldspar augen within an anastomosing, mica-rich, schistose matrix.
