The hardness of a mineral can be determined by a scratch test. mineralogy output, consequently yielding better porosity and water saturation calculation. Fe occur in high concentration in Upper Suraj pay. The ratio of Fe and Al is abnormally high more nearly typical of hydrated iron oxide. The mineralogical evaluation suggests that this pay is clayey with minerals comprising quartz, siderite, and limonite. determined in plane polarized light.

It occurs only when negative acceleration takes place. We know a = v-u/t Hope this answer helps you.

The birefringence and retardation of isotropic crystals are always zero. Definition of retardation In crystal optics, the amount by which the slow wave falls behind the fast wave during passage through an anisotropic crystal plate. Retardation depends on plate thickness and the difference in refractive indices of its two principal directions. The waveplate is characterized by the amount of relative phase, Γ, that it imparts on the two components, which is related to the birefringence Δn and the thickness L of the crystal by the formula Γ = 2 π Δ n L λ 0 , {\displaystyle \Gamma ={\frac {2\pi \,\Delta n\,L}{\lambda _{0}}},} Retardation, r, increases linearly with both the thickness, t, of a specimen and with the birefringence, n 2-n 1: the greater the thickness, the greater the retardation (the thicker the crystal, the farther behind the slow ray gets from the fast ray); the greater the difference between the refractive indices (birefringence) to begin with, the greater the retardation (or higher the interference ΔTΔ= c { (d/Vo) – (d/Ve)}Δ= d { (c/Vo) - (c/Ve)} {n1= c/Vo , n2= c/Ve }Δ = d (n1-n2)Here n1 and n2 are the refractive indices of calcite crystal plate for O-ray andE-ray respectively.

Environmental mineralogy studies complex and very different conditions of the origin of minerals, understand element behavior in echo-systems, natural and industrial effects of minerals, and mitigates potential contamination problems. 5.
