The blood pressure decreases and complaints, such as fatigue and lassitude, make themselves felt. These symptoms may also occur after the meal because the blood gathers in the area of the digestive organs and is missing in the brain. Dizziness.
Metamorphic rocks have been modified by heat, pressure and chemical processes, usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks. Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.
Rockhound. The foliations of metamorphic rock are created by a reorganization of the minerals in the parent rock. The foliations, layers, or bands, are formed at right angles to the direction of the pressure which is causing the foliation.n example of a foliated rock is slate. You can distinguish a  foliated rock by the fact that the minerals line up in a sheet-like  appearance. They are formed by pressure s â¦ queezing the minerals into  alignment. Answered.
