1.1 Definition

Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

1.3 Etymology

From pseudo- +‎ tachylite, a glassy rock generated by frictional heat within faults.

From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

5 Formation

5.1 Formation

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.

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Pseudotachylite and Conglomerate Properties

Know all about Pseudotachylite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Pseudotachylite belongs to Metamorphic Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Pseudotachylite is Quench whereas that of Conglomerate is Clastic. Pseudotachylite appears Dull and Soft and Conglomerate appears Shiny and Rounded. The luster of Pseudotachylite is vitreous while that of Conglomerate is dull. Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Pseudotachylite are creating artwork, gemstone and that of Conglomerate are cemetery markers, in aquifers, tombstones.
