Supracrustal rocks are those sedimentary or volcanic rocks deposited or formed over the basement rocks which were later metamorphosed.
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
ROCKS are residual or in_place parent material.The rocks may be..Igneous rocks,Sedimentry rocks and Metamorphic rocks..
Igneous rocks
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
Sedimentary rocks are made from weathered down materials, often rocks, so they can be argued that they come from other rocks. Metamorphic rocks are formed from pre-existing rocks; these rocks go under extreme heat and pressure. In conclusion, metamorphic rocks are definitely made from other rocks, and sedimentary rocks are sometimes made from other rocks. Sedimentary rocks are always made of other rocks,extrusive and intrusive igneous rocks as well as metamorphic rocks are weathered and eroded by agents like water , wind and sunlight and are stratified and compacted to form sedimentary rocks. Hence, even if metamorphic rocks are made from rocks, sedimentary rocks are definitely made from other rocks. Eg: sedimentary rock shale gets metamorphosed into slate and further metamorphosed into shcist which is the parent material of granite which can be effected by agents of weathering and erosion into sedimentary rocks again.
The rocks are not a "greenstone belt" strictly speaking because they have been so metamorphosed that the original low-grade metamorphic mineral assemblage has been transformed to pyroxene and then retrogressed to hornblende (amphibole) which is black. Instead, geologists refer to such rocks as a supracrustal belt; an assembly of volcano-sedimentary rocks of a common origin for which there is no longer a basement rock contact. The Nuvvuagittuq supracrustal belt is composed of amphibolites mostly metamorphosed basalts and altered tuffs(?) that are poor in CaO (erroneously termed "faux amphibolites"). In addition to these rocks, there are banded iron-formations, quartzites, and some clastic metasediments. The rocks were emplaced around 3.8 billion years ago and carry hints of being derived from some re-worked much older (>4.3 billion years old?) mafic crust. Research continues.
tere mare many rocks but alll rocks are like rocks they always bscome rocks and roks say with me rocks remains rocks rocks remains rocks rocks remains rocks rocks remains rocksrocks remains rocks rocks remains rocks rocks remains rocks rocks remains rocks rocks remains rocksrocks remains rocksrocks remains rocks vrocks remains rocks v rocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocks v rocks remains rocksrocks remains rocks rocks remains rocksrocks remains rocksrocks remains rocks rocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksvrocks remains rocksrocks remains rocksrocks remains rocks v vrocks remains rocksrocks remains rocks rocks remains rocksrocks remains rocksrocks remains rocksvrocks remains rocks rocks remains rocks rocks remains rocksrocks remains rocks v v rocks remains rocks rocks remains rocks v rocks remains rocks rocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocksrocks remains rocks
igneous rocks
shariq rocks and Alvin rocks and Adrian rocks!!!! Tommy also rocks!!!! oh and yaseen rocks!!!! and marcellus rocks!!!! and nick b. rocks!!!! and alex t. rocks!!!! and Abib rocks!!!! oh and I think I, k*v*n rocks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
They are Sedimentary rocks, Igneous rocks, and Metamorphic rocks.
metamorphic rocks.
metamorphic
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.
igneous rocks,sedimentary rocks, and metamorphic rocks.
Yes. Volcanic rocks are extrusive igneous rocks.
Small Rocks, and smaller rocks, and even smaller rocks.
Igneous rocks.
