| Title | Marble containing phlogopite and chondrodite |
|---|---|
| Description | Marble is a general name for rocks formed by metamorphism of a limestone or dolostone. Marbles are dominated by calcite or dolomite, but some contain any of a number of interesting accessory minerals. This sample contains very light brown flakes of phlogopite (Mg-rich biotite) and darker brown granular grains of chondrodite (an Mg-Fe mineral related to olivine). |
