How to Identify Metamorphic Rocks in Thin Section and Hand Sample - GEO GIRL

Learn to identify metamorphic rocks in thin section and hand sample through this comprehensive 37-minute video tutorial. Explore various metamorphic rock types, including marble, quartzite, phyllite, schist, amphibolite, eclogite, gneiss, serpentinite, slate, and soapstone. Examine their characteristic minerals, textures, and formation processes. View real-time thin section rotations and hand sample images to develop practical identification skills. Compare similar rock types and understand key distinguishing features. Gain insights into metamorphic petrology concepts such as foliation, porphyroblasts, and poikiloblasts. Access additional resources and references for further study in metamorphic rock identification and analysis.
