Protolith To Marble

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

Protolith to marble. A protolith is the parent rock. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Metamorphic rocks have protoliths and limestone or dolomite are the protoliths of marble. What is the protolith of gneiss.

Your textbook incorrectly uses the term source rocks for the pre existing rock. They are commonly used as a decorative stone. What is the protolith of amphibolite. Marble a white or uniquely variegated type of limestone that has been exposed to extreme heat and pressure has a long history of being favored by artisans and builders from michelangelo s.

What is the protolith of quartzite. What is the protolith of skarn. Marble a limestone or dolostone made up only of calcite or dolomite will metamorphose to a marble which is made mostly recrystallized calcite or dolomite. The term source rock used in sedimentary deposits to describe the rock from which petroleum is derived or the rock that erodes to produce sediment and later sedimentary rock.

What is the protolith of slate phyllite and schist. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Marbles have a variety of colors and are often complexly banded. You may try to scratch the surface with a needle.

What is the protolith of marble. Another and even better test is to use acid. Quartzite may resemble marble at first. If you can do it then it is probably marble.

Marbles may have bands of different colors which were deformed into convoluted folds while the rock was ductile. Metamorphic rocks have protoliths and limestone or dolomite are the protoliths of marble. A protolith is the parent rock. Marble marble is a metamorphic rock made up almost entirely of either calcite or dolomite for which the protolith was either limestone or dolostone respectively.

The recrystallization usually obliterates all fossils. Calcite the main constituent of most marbles reacts vigorously with dilute hydrochloric acid but there is no reaction with quartz. The pre existing rock is called either the parent rock or the protolith. Width of sample 13 cm.
