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.

More about Troctolite and Turbidite
Here you can know more about Troctolite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Turbidite consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Troctolite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Troctolite is available in dark grey to black colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Troctolite is Veined and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Troctolite vs Turbidite. The hardness of Troctolite is 7 and that of Turbidite is 3. The types of Troctolite are Ultramafic rock whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Troctolite is black while that of Turbidite is white, greenish white or grey. The specific heat capacity of Troctolite is 0.84 kJ/Kg K and that of Turbidite 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.Troctolite is impact resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
