Ganister vs Pseudotachylite

Definition

Definition

A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

Etymology

From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam
From pseudo- +‎ tachylite, a glassy rock generated by frictional heat within faults.

Formation

Formation

Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Ganister and Pseudotachylite

Here you can know more about Ganister and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Pseudotachylite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Pseudotachylite is available in black, brown, green, grey, pink, white colors. Appearance of Ganister is Rough and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Ganister vs Pseudotachylite. The hardness of Ganister is 6-7 and that of Pseudotachylite is 7. The types of Ganister are Siliceous rock whereas types of Pseudotachylite are Cataclastic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister is white while that of Pseudotachylite is light to dark brown. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Pseudotachylite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ganister is heat resistant, impact resistant, pressure resistant whereas Pseudotachylite is heat resistant.
