Answer: Option A
Solution
Answer: Option A
Solution:
A primary mineral is any mineral formed during the original crystallization of the host igneous primary rock and includes the essential minerals. Quartz is a primary mineral.A clay mineral is hydrous aluminum phyllosilicates, usually form in the presence of water. An illite is a group of closely related non-expanding clay minerals.
Sedimentary rock are formed from the deposits of pre-existing rocks or pieces of the once-living organism that accumulate on the Earth's surface. Sandstone is a clastic sedimentary rock.
Metamorphic rock is a class of rocks formed from heat and pressure for the alteration of preexisting rocks into completely new rocks. Marble is an example of metamorphic rock composed of recrystallized carbonate minerals.
