5.6: Metamorphism and Metamorphic Rocks

The original fine grained, iron and magnesium rich, minerals of olivine and pyroxene have recrystallized through metamorphic processes to form the greenstone rock. Greenstone is very important to Historical Geology, preserving some of the oldest slivers of early ocean crust. This is discussed in much more detail elsewhere in this text.

STONE INLAY IN WOODTURNINGS Stephen Hatcher

enough to provide lasting beauty. Within several minerals I have found a wide range of colors and 're ectivity'. Re ectivity is something akin to chatoyance in wood where the coarsely crushed stone catches the light with facets associated with the mineral crystal structure. Simply put: it sparkles and shimmers in bright light.
