Definition
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Etymology
From German Troklotit, from Greek trōktēs, a marine fish (taken to be trout)
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
Formation
Troctolite 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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Troctolite and Turbidite Properties
Know all about Troctolite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Troctolite belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Troctolite is Phaneritic whereas that of Turbidite is Mud-rich, Sandy. Troctolite appears Veined and Shiny and Turbidite appears Dull and Banded. The luster of Troctolite is while that of Turbidite is metallic. Troctolite is available in dark grey to black colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Troctolite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Turbidite are cemetery markers, creating artwork.
