Metamorphic Rock Dichotomous Key -

Identifying metamorphic rocks using a dichotomous key is a process of elimination that relies on observable physical properties like , foliation , and mineral composition . By answering a series of "yes" or "no" questions, you can narrow down a specimen to its specific type. Step-by-Step Identification Guide

The first and most critical split in a metamorphic key is whether the rock is (shows layering or alignment of minerals) or non-foliated (massive or granular without obvious layering). Classification of Metamorphic Rocks Metamorphic Rock Dichotomous Key
