Clay minerals and quartz are the chief constituents of most sedimentary rocks in this category. To answer why, clay minerals are the most abundant product of the chemical weathering of silicate minerals, especially the feldspars. Clays are fine-grained minerals with sheetlike crystalline structures similar to the micas. Quartz is abundant because it is extremely durable and very resistant to chemical weathering. Thus, when igneous rocks such as granite are attacked by weathering processes, individual quartz grains are freed.
What else can I help you with?
Do detrital sedimentary rocks have clastic textures?
Yes, detrital sedimentary rocks have clastic textures. Clastic textures are composed of fragments or grains derived from pre-existing rocks or minerals, which are then compacted and cemented together to form the new rock. Detrital sedimentary rocks, such as sandstone and shale, are formed through the deposition and lithification of these clastic particles.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
The most common minerals in clastic sedimentary rocks are likely?

What are the two main types of sedimentary rocks?
The two main types of sedimentary rocks are clastic (detrital) rocks, which are made of pre-existing rock fragments cemented together, and chemical rocks, which form from minerals that precipitate out of solution.
Which major component of detrital sedimentary rocks only rarely occurs as a primary mineral in igneous rocks?
The mineral quartz is the major component of detrital sedimentary rocks and rarely occurs as a primary mineral in igneous rocks. Quartz is resistant to weathering and is one of the most abundant minerals in the Earth's crust.
What minerals are most common in detrital sedimentary rocks?
The most common minerals found in detrital sedimentary rocks are quartz, feldspar, and clay minerals. These minerals are often derived from the erosion and weathering of igneous and metamorphic rocks.
What minerals are the most common in detrital sedimentary rocks?
Quartz and Clay.
What minerals are most common in detrital sedimentary rocks and why are these minerals so abundant?
We know silicate minerals are the most abundant in detrital sedimentary rocks.Quartzv is a tectosilicate mineral.So quartz is the most abundant and other silicate minerals are also very common in these rocks.
What type of sedimentary rocks forms when particles of minerals and rocks are cemented together?
Detrital sedimentary rock. clastic sedimentary A+
What are detrital rocks formed from?
Detrital sedimentary rocks, also called clastic sedimentary rocks, are composed of rock fragments that have been weathered from pre-existing rocks. They are the most common rocks on the surface of the earth.
What is the most abundant mineral in detrital sedimentary rocks?
Quartz is the most abundant mineral in detrital sedimentary rocks. It is highly resistant to weathering and erosion, making it a common component of sedimentary deposits.
What is a type of detrital sedimentary rock?
Detrital rocks are sedimentary rocks that are composed of particles of weathered and eroded igneous, metamorphic, or other sedimentary rocks that have been deposited, compacted, and cemented together. Sandstone, conglomerate, shale, and breccia are examples of detrital sedimentary rocks.
Do detrital sedimentary rocks have clastic textures?
Yes, detrital sedimentary rocks have clastic textures. Clastic textures are composed of fragments or grains derived from pre-existing rocks or minerals, which are then compacted and cemented together to form the new rock. Detrital sedimentary rocks, such as sandstone and shale, are formed through the deposition and lithification of these clastic particles.
Particle size is the primary basis for distinguishing among various detrital sedimentary rocks?
Detrital sedimentary rocks are classified based on the particle size of the grains they contain. These rocks include conglomerate, sandstone, and shale, with conglomerate having the largest particles, followed by sandstone and shale with finer particles. The size of particles in a detrital sedimentary rock can provide information about the environment in which the rock was formed.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
