What is schists parent rock type?
The original parent rock (or protolith) of mica schist is shale. Phyllite could also be considered the parent rock as mica schist is a more highly metamorphosed phyllite.
What is a metamorphic rocks parent?
In the earth sciences, parent rock, also sometimes substratum, is the original rock from which younger rock or soil is formed. Parent rock can be sedimentary, igneous or metamorphic. In the context of metamorphic rocks, the parent rock (or protolith) is the original rock before metamorphism occurred.
What is Calcites parent rock?
Parent Rock: limestone or chalk. Nature of Metamorphism: burial, contact or regional (can not be distinguished in hand sample) Impt. Characteristics: composed almost entirely granoblastic calcite; more lithified and coarser grained than limestone or chalk. AMPHIBOLITE.
What is the parent rock of basalt?
| Foliated Metamorphic Rocks | ||
|---|---|---|
| Crystal Size | Mineralogy | Parent Rock |
| medium to coarse | amphibole, plagioclase, biotite, quartz | basalt |
| medium to coarse | plagioclase, orthoclase, quartz, biotite, amphibole, pyroxene | basalt, granite, shale |
| Nonfoliated Metamorphic Rocks |
What is Metaconglomerate parent rock?
Metaconglomerate is a rock type which originated from conglomerate after undergoing metamorphism. Foliated metaconglomerate is created under the same metamorphic conditions that produce slate or phyllite, but with the parent rock (protolith) being conglomerate, rather than clay.
What is quartzites parent rock?
Quartzite is a metamorphic rock, formed when its parent rock, sandstone, is buried then heated and/or compressed. Sandstone is a sedimentary rock, formed from weathered or eroded remains of other rocks.
What is Quartzite parent rock?
Where can you find breccia rock?
Breccia can be found near landslides, fault zones and cryptolithicexplosion events. A breccia zone located near fault zones can varydrastically in size from inches to several yards. The other type is a gray rock known as lunar breccias. They are found at volcanic eruptions on Earth.
