Protolith in the formation of marble. Metamorphosed limestone is marble. The weathering profiles from bottom to top change from weakly serpentinized peridotitic protolith to. Blueschists form where there s extreme pressure and low heat which does not. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

The surface weathering profile is significant and variable both vertically and laterally forming 10 distinct lithostratigraphic units. The preexisting rock that is subsequently altered to form a metamorphic rock is termed a. A limestone b sandstone c shale d slate. Commonly serves as a protolith in the formation of slate.

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. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. Protolith commonly serves as a protolith in the formation of marble. Foliated metamorphic rocks possess.

Mineral grains in preferred orientations or patterns of association such as banding. Which of the following commonly serves as a protolith in the formation of marble. Metamorphic rocks have protoliths and limestone or dolomite are the protoliths of marble. Marble is commonly used for sculpture and as a building material.

What is the protolith of marble. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The preexisting rock which is subsequently altered to form a metamorphic rock is termed a. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

Limestone a protolith is the parent rock that is metamorphosed into a different rock. Mylonites form due to shearing stress along faults deep in the crust not the heat of convergent boundaries. The deposit is hosted by a peridotitic protolith exposed in the form of an elongated low lying hill. Crystals dissolving with atoms and ions migrating and reorganizing as new crystals.
