The rheology and strength of the Earth's lithosphere have been a topic of debate since the beginning of the 20th century when Joseph Barrell introduced the concept of a strong lithosphere overlying a fluid asthenosphere (Barrell, 1914).This concept constitutes an integral part of plate tectonics (e.g. Le Pichon et al., 1973, Watts, 2001, Turcotte and Schubert, 2002) …

The earth's crust is composed of many kinds of rocks, each of which is made up of one or more minerals. Rocks can be classified into three basic groups: igneous, sedimentary, and metamorphic. Igneous rocks are the most common rock type found in the earth's crust. They form when magma cools and crystallizes subsurface (intrusive igneous rocks ...

(5) Granite: is an igneous rock that is composed of four minerals. These minerals are quartz, feldspar, mica, and usually hornblende. Granite forms as magma cools far under the Earth's surface. Because it hardens deep underground, it cools very slowly. This allows crystals of the four minerals to grow large enough to be easily by the naked eye.
