They are able to slice the granite into extremely thin layers, observe it under a microscope, and view the amount and type of minerals that are present.

How do geologist determine the minersl composition if granite?
by observing it,we properties of different minerals,so by observing it we are able to know which mineral is which
What is the mineral composition of granite?
the mineral composition of granite isfeldspar,diamond,talc,chalk and other plutonic rocks
Why do geologist not consider coal to be a mineral?
A mineral must have a definite chemical composition and a crystalline structure, neither of which apply to coal.
What is the percent of quartz found in granite?
12 percent on a mineral composition table
What minerals determine the color of granite?
The color of granite is primarily determined by the presence of mineral crystals such as feldspar, quartz, and mica. The composition and concentration of these minerals contribute to the various colors and patterns seen in granite rocks. Additional minerals like hornblende and amphibole can also influence the coloration of granite.
Would the composition of a mineral be studied by a geologist?
Yes, a geologist would study the composition of a mineral as part of their analysis of rocks and minerals in the Earth's crust. Understanding the chemical and physical properties of minerals helps geologists identify different rock types and formations, as well as the processes that formed them.
What continental crust has the average composition of?
Granite. Most of the crust is composed of granite. Feldspar is the most common mineral in the earth's crust.Silicon, (Si) and Alluminium, (Al).
A rock that consists mostly of mineral quartz will have a composition very similar to?
Quartz is a major mineral in granite. Therefore, a rock consisting mostly of quartz will have a composition similar to granite. Both rocks are light in color and have a high silica content.
How geologists determine the mineral composition of granite?
The minerals are for the most part observable in a coarse grained igneous rock such as granite. If necessary, however, thin slices of rocks are made to be viewable under a microscope that could help identify trace minerals.
How do geologists determine the mineral compostion of granite?
They basically cut or slice the granite apart exposing the "real" minerals inside.

How do you recognize Gabbro from granite?
Gabbro and granite can be distinguished by their mineral composition and texture. Gabbro is an intrusive igneous rock primarily composed of pyroxene and plagioclase feldspar, giving it a darker color and a coarser grain size. In contrast, granite contains quartz, feldspar, and mica, which results in a lighter color and a more varied mineral composition. Additionally, granite typically has a more granular texture, while gabbro may appear more uniform.
