Granulite - Wikipedia

The most common mineral assemblage of granulite facies consists of antiperthitic plagioclase, alkali feldspar containing up to 50% albite and Al 2 O 3-rich pyroxenes. Transition between amphibolite and granulite facies is defined by these reaction isograds: amphibole -> pyroxene + H 2 O biotite -> K-feldspar + garnet + orthopyroxene + H 2 O.

Simulation 6A1 allows K-feldspar to react until equilibrium with gibbsite is reached. This is set up in the EQUILIBRIUM_PHASES input by specifying equilibrium for gibbsite (saturation index equals 0.0) and an alternative reaction to reach equilibrium, KAlSi3O8 (the formula for K-feldspar). A large amount of K-feldspar (10.0 mol) is present to ensure that equilibrium with gibbsite can be obtained.

Dartmoor tin-mining - Wikipedia

The tin mining industry on Dartmoor, Devon, England, is thought to have originated in pre-Roman times, and continued right through to the 20th century, when the last commercially worked mine (Golden Dagger Mine) closed in November 1930 (though it saw work during the Second World War). From the 12th century onwards tin mining was regulated by a stannary parliament which had its own laws.
