Earth-Sun Relationship General Division of Seasons Generally, the division of the year into seasons varies with latitude. In middle latitudes, the year is divided into ‘autumn’, ‘winter’, ‘spring’, and ‘summer’. The terms ‘summer’ and ‘winter’ are not as significant in the tropics. Instead, division is usually made in terms of rainfall, such as the ‘rainy […]

An aluminosilicate mineral is a type of mineral that contains both aluminum and silicon in its chemical composition. Sillimanite(Al2SiO5)(Orthorhombic) Sillimanite is a high-temperature polymorph of Al2SiO5 and occurs as colourless or white acicular to fibrous crystals in high grade metamorphosed pelitic rocks. It has high relief and straight extinction. a 1.653—1.661 b 1.657—1.662 g 1.672—1.683
असंगति (Unconformity) असंगति भूवैज्ञानिक संरचना में वह स्थिति होती है जहां पर चट्टानों की दो परतों के बीच एक अंतराल या रुकावट होती है, जो लंबे समय तक अपक्षय, अपरदन या अवसादन की अनुपस्थिति के कारण उत्पन्न होती है। यह स्थिति चट्टान के रिकॉर्ड में समय के गैप को दर्शाती है, जहां पुराने और नए
Garnet Group The minerals of the garnet group crystallize in the isometric system and belong to the Neso silicate group of silicates. General Formula X^{+2}_3 Y^{+3}_2 Z^{+4}_3O_{12} Where: X+2 = Ca, Mg, Fe, Mn (occupying dodecahedral sites) Y+3 = Fe, Al, Cr (occupying octahedral sites) Z+4 = Si, Ti (occupying tetrahedral sites) 1) Pyralspite Series

Olivine Group Introduction General Formula: R2SiO4, where R = Mg, Fe, Mn, & Ca. Structure The structure consists of independent SiO4 tetrahedra linked by divalent (Mg, Fe) atoms in octahedral coordination (each of which has six nearest oxygen neighbors). Octahedra in a structure are represented as (M): M1 < M2 < M3 < M4 Note:
