What is the parent rock for quartzite?

What is the parent rock for quartzite?

Quartzite is a metamorphic rock formed under moderate to high- grade metamorphism that exhibits both foliated and nonfoliated structure. The parent rock to quartzite is sandstone.

What type of rocks is quartzite?

quartzite, sandstone that has been converted into a solid quartz rock. Unlike sandstones, quartzites are free from pores and have a smooth fracture; when struck, they break through, not around, the sand grains, producing a smooth surface instead of a rough and granular one.

What are the parent rocks of quartzite and marble?

Marble comes from dolostone (limestone with dolomite) or limestone. Quartzite comes from quartz sandstone when the quartz grains of the sandstone are fused due to pressure and heat.

Which is a Protolith of quartzite?

quartzite—quartzite is a metamorphic rock made almost entirely of quartz, for which the protolith was quartz arenite. Because quartz is stable over a wide range of pressure and temperature, little or no new minerals form in quartzite during metamorphism.

What is marble’s parent rock?

Limestone is a sedimentary rock that is composed of the mineral calcite. The presence of the foliated rock, likely slate, suggests that before this rock metamorphosed it was composed of limestone (the parent rock of marble) layered with small-grained sedimentary rocks, like siltstone or shale.

Why is quartzite a metamorphic rock?

The metamorphic transformation of the primary quartz dominated sedimentary rocks (e.g., sandstone) into quartzite is usually caused by high-temperature and high-pressure conditions, usually related to tectonic movement and compression within orogenic belts.

What minerals are present in quartzite?

Quartzite: A granoblastic metamorphic rock consisting mainly of quartz (>90%) and formed by recrystallization of sandstone or chert by either regional or thermal metamorphism. Accessory minerals include feldspar, micas, and detrital heavy minerals such as titanite, magnetite, zircon and rutile.

What is protolith rock?

The original rock that has undergone metamorphism is called the protolith. Protolith can be any type of rock and sometimes the changes in texture and mineralogy are so dramatic that is difficult to distinguish what the protolith was. Note that diagenesis and weathering are also a changes in form that occur in rocks.

What is Marble’s parent rock?

What is the parent rock of amphibolite?

amphibolite, a rock composed largely or dominantly of minerals of the amphibole group. The term has been applied to rocks of either igneous or metamorphic origin. Mafic igneous rocks (e.g., basalts and gabbros) and sedimentary dolomite can be the parent rocks of amphibolite.

What is phyllite parent rock?

phyllite, fine-grained metamorphic rock formed by the reconstitution of fine-grained, parent sedimentary rocks, such as mudstones or shales.
