What type of metamorphism is schist?

Schist is medium grade metamorphic rock, formed by the metamorphosis of mudstone / shale, or some types of igneous rock, to a higher degree than slate, i.e. it has been subjected to higher temperatures and pressures. What type of metamorphism forms schist? Most regional metamorphism is accompanied by deformation under non-hydrostatic or differential stress conditions.

How does geology affect life?

How does geology affect our life? Geologists play an integral role in studying seismic activity, weather patterns and tectonic movements to assist in preparing for potential adverse events. They also assist in engineering structures to withstand flooding, earthquakes and more. How does geology impact everyday life? Geology in everyday life is not restricted to resources.

What is the difference between Nautiloids and Ammonoids?

A primary difference between ammonites and nautiloids is the siphuncle of ammonites (excepting Clymeniina) runs along the ventral periphery of the septa and camerae (i.e., the inner surface of the outer axis of the shell), while the siphuncle of nautiloids runs more or less through the center of the septa and camerae. Is ammonite the

Where does hematite come from?

The most important deposits of hematite are sedimentary in origin.

It can crystallize during the differentiation of a magma or precipitate from hydrothermal fluids moving through a

What is the difference between a crack and a fissure?

Here’s how: A crack is a broken piece of countertop that is most of the time, chipped, uneven, and widely separated and is usually the result of man-made stresses. On the other hand, a fissure is a part of the stone that resembles a crack, yet it is a result of natural geological formation or

How does glaciation turn interlocking spurs into truncated Spurs?

How are truncated spurs formed? Definition: Truncated spurs are landforms that occur in glaciated areas. When a valley fills with a glacier, any land which is in the way of the moving glacier will be eroded away. Truncated spurs have steep sides which show this erosion. This erosion can also be caused by moving water.
