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
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Troctolite and Marble Properties
Know all about Troctolite and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Troctolite belongs to Igneous Rocks while Marble belongs to Metamorphic Rocks.Texture of Troctolite is Phaneritic whereas that of Marble is Granular. Troctolite appears Veined and Shiny and Marble appears Veined and Shiny. The luster of Troctolite is not available while that of Marble is dull to pearly to subvitreous.
