Mylonite mineral,light micrograph. The term mylonite refers to rocks and minerals that have been placed under great strain deep underground by large-scale seismic movements. These strains cause the mineral content to change and deform. When studied in thin-section,as here,features such as porphyroclasts of feldspar (grey areas) are seen floating in a matrix of altered gneiss. This sample is around 2.7 centimetres high | |
