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.
Just a guess--quartz and feldspar. Feldspar might be replaced with clay minerals.
Answer: Clay and Quartz are the pair of minerals most common in detrital sedimentary rocks.
Quartz and Clay.
the most common minerals in clastic sedimentary rocks are likely
No. The rocks you describe are clastic or detrital sedimentary rocks.
yes
quartz and clay
They are rocks formed from pieces of pre-existing rocks or organic debris.
The most common minerals in detrital sedimentary rocks are quartz grains and clay.
Quartz and Clay.
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.
Detrital sedimentary rock. clastic sedimentary A+
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.
The primary basis for distinguishing among various detrital sedimentary rocks is particle size. The chief constituents of these rocks are quartz and clay minerals.
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.
