The other class, called calcic skarns, are the replacement products of a limestone protolith with dominant mineral assemblages containing garnet, clinopyroxene, and wollastonite. [ 3 ] Rocks that contain garnet or pyroxene as major phases, and that are also fine-grained, lack iron, and have skarn-like appearances, are generally given the term ...

Metamorphism is the transformation of existing rock (the protolith ) to rock with a different mineral composition or texture .
Eclogites are defined as bi-mineralic, broadly basaltic rocks which have been classified into Groups A, B and C based on the chemistry of their primary mineral phases, garnet and clinopyroxene. [3] [4] The classification distinguishes each group based on the jadeite content of clinopyroxene and pyrope in garnet. [4]
Limestone can withstand a high level of abuse, including most forms of abrasion damage and impact damage. Though, it's worth noting that limestone is highly susceptible to staining, so it's ...
Uvarovite is a chromium-bearing garnet group species with the formula: Ca 3 Cr 2 (Si O 4) 3. It was discovered in 1832 by Germain Henri Hess who named it after Count Sergei Uvarov (1765–1855), a Russian statesman and amateur mineral collector. [2] It is classified in the ugrandite group alongside the other calcium-bearing garnets andradite ...
