What are the most common minerals in clastic rocks?
clay minerals and quartz
Why are quartz and feldspar the main minerals in clastic rocks?
Quartz and feldspar are the main minerals in clastic rocks due to their durability and resistance to weathering. Quartz is highly stable and can withstand physical and chemical breakdown, making it a common component in sediment. Feldspar, while less resistant than quartz, is abundant in the Earth's crust and contributes significantly to the composition of these rocks. Together, they form the primary constituents of clastic sediments, reflecting their origins from the erosion and weathering of pre-existing rocks.
What is the principal mineral in sandstone?
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.
What is the cementing material between the grains in a sedimentary rock?
The cementing material could be calcite, clay minerals, iron minerals, or quartz in a clastic sedimentary rock.
What rock is clastic and does not effervesce under acid?
Sandstone is an example of a clastic rock that does not effervesce under acid. It is primarily composed of sand-sized grains, often quartz, and is formed through the lithification of sediment. Unlike limestone, which contains calcite and reacts with acid, sandstone's mineral composition makes it resistant to effervescence.

What types of minerals are clastic sedimentary rocks made of?
Clastic sedimentary rocks are made of broken pieces of preexisting rock that are compacted together. The mineral quartz makes up sixty percent of the clastic sedimentary rocks.

What are standstones made of?
Sandstones are made out of sand sized particles or rock grains. Sandstones are clastic sedimentary rock. Some sandstone is composed of feldspar or quartz.

What are clastic sdimentary rocks?
Clastic sedimentary rocks are formed from particles of pre-existing sedimentary, metamorphic, or igneous rock that are deposited, compacted, and cemented together by natural processes.Clastic sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz.
Is chalk clastic chemical or organic?
It is clastic
Is breccia chemical clastic or organic?
clastic
