What Are Metamorphic Rocks? - Mining

Metamorphic rocks constitute a large portion of the Earth’s crust. They are classified based on their texture and metamorphic facies into foliated and non-foliated metamorphic rocks. Foliated metamorphic rocks have a layered or banded surface caused by the exposure to high heat and pressure. Examples of foliated rocks include slate, schist, phyllite and gneiss. Alternatively, non-foliated rocks

Metamorphic Rocks TAKING THE HEAT AND

All rocks after they have been solidified one of two things (or different combinations) happen. Either they are broken down/eroded at the surface or they solidify deep in the earth. Either way, the immense pressures and temperatures within the earth will begin to change any rock, sedimentary, igneous or even other metamorphic into something new and maybe more exciting.

Geology Fundamentals: Metamorphic Rocks

01-03-2021  Metamorphic rocks form as the result of a solid-state transformation of preexisting rocks. Parent rock or protolith is the term for the preexisting rock that is metamorphosed. The main agents of metamorphism (which means “to change”) are heat, pressure, and chemically active fluids. Unlike igneous rocks, metamorphic rocks do not melt.

Gold Deposits in Metamorphic Rocks of Alaska

The mining industry grew rapidly in Alaska after the United States purchased the region from Russia in 1867. By 1870, gold was being mined near Windham Bay and near Sitka, in southeastern Alaska. The first major hard-rock gold mining began at the Alaska-Juneau, Perseverance, and Treadwell mines near present-day Juneau following the discovery of placer gold near tidewater in 1880.
