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
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks

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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

More about Troctolite and Jaspillite
Here you can know more about Troctolite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Jaspillite consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Troctolite vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Troctolite is Veined and Shiny and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Troctolite vs Jaspillite. The hardness of Troctolite is 7 and that of Jaspillite is 3. The types of Troctolite are Ultramafic rock whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. 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 Jaspillite is white. The specific heat capacity of Troctolite is 0.84 kJ/Kg K and that of Jaspillite is 3.20 kJ/Kg K.
