The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. Analogous to recycling a Coke can, where an old can ...

Temperature and pressure conditions of metamorphism in the Peavy Node area in northern Michigan have been estimated from the garnet-biotite geothermometer and garnet-plagioclase-aluminosilicate-quartz ...

Sedimentary rocks are made up of pieces of older rocks (igneous, metamorphic, and sedimentary) and organic remains (shells, bone, etc.). When rocks break apart from erosion they are transported by ...

The easternmost portion of the granite of the Mesabi Range, Minnesota, was regarded by C. K. Leith as intrusive in the Animikian iron formation, and mapped as Embarras granite. Obervations in the ...

There are three types of rock found on Earth. These are igneous, metamorphic and sedimentary. Each rock type is formed in a different way. For example, the rock malachite is mostly made of the ...

Arc magmatism is thought to have played a central role in creating continental crust because magmatic rocks — erupted as andesitic lavas and intruded to form plutons — found in subduction-related ...

A unique type of diamond has been discovered in Australia for the first time, but they're invisible to the naked eye. Metamorphic diamonds are so small it took researchers almost 18 months to detect ...

Last week, Professor of Earth & Oceanographic Science Rachel Beane, with help from students, gave a talk on the craggy coast of Bailey Island, inviting the public to come learn about the unusual rock ...

Igneous rocks close igneous rockIgneous rocks are those which have been formed by the cooling and solidification of molten rock (magma) from underneath the earth’s crust. are formed by magma from the ...
