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.

Tephrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Conglomerate and Tephrite Properties

Know all about Conglomerate and Tephrite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Tephrite belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Tephrite is Aphanitic to Porphyritic. Conglomerate appears Shiny and Rounded and Tephrite appears Vesicular. The luster of Conglomerate is dull while that of Tephrite is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Tephrite is available in black, brown, colourless, green, grey, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones and that of Tephrite are production of lime, soil conditioner.
