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
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Troctolite and Suevite Properties
Know all about Troctolite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Troctolite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Troctolite is Phaneritic whereas that of Suevite is Earthy. Troctolite appears Veined and Shiny and Suevite appears Banded. The luster of Troctolite is while that of Suevite is earthy. Troctolite is available in dark grey to black colors whereas Suevite 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
