1.1 Definition

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

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

1.3 Etymology

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

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

5 Formation

5.1 Formation

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

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.

All about Conglomerate and Pseudotachylite Properties

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