The mineral calcite is an example of a carbonate mineral. Carbonate minerals contain the carbonate ion (CO3) in their chemical composition.
The minerals that make up a rock determine how fast it weathers to a large extent. This is mainly true when it comes to chemical weathering.

first you have to determinate in witch step of the process you gett the birefringence. Usually it is in the molding of layer-0
A Berylometer is a device used to measure the birefringence of materials, particularly gems or minerals such as beryl. Birefringence is the difference in refractive index between light polarized in different directions. The Berylometer helps gemologists and scientists analyze the optical properties of beryl gemstones.
There are no exacting standards to determine the value of minerals
Birefringence is a property of certain materials where they exhibit different refractive indices depending on the polarization and propagation direction of light passing through them. This causes double refraction, splitting a single ray of light into two separate rays that travel at different speeds. Birefringence is commonly found in crystals, certain plastics, and liquid crystals.

it is by weight or heft them
Birefringence is a property of anisotropic materials where light traveling through the material splits into two different paths with different refractive indices. This causes the light to be doubly refracted, resulting in the formation of two distinct refracted rays. Birefringence is commonly observed in materials like calcite and quartz.
It's used to determine the hardness of minerals - from talc (1) to diamond (10).
