Definition
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass
Jaspillite is an iron rich chemically formed rock which is common in banded iron formation rocks

Archaeological Significance
Formation
Shoshonite 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 Shoshonite and Jaspillite
Here you can know more about Shoshonite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Jaspillite consists of mineral content and compound content. The mineral content of Shoshonite includes 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 Shoshonite vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Shoshonite is Dull and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Shoshonite vs Jaspillite. The hardness of Shoshonite is 6 and that of Jaspillite is 3. The types of Shoshonite are Intermediate volcanic 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 Shoshonite is white to grey while that of Jaspillite is white. The specific heat capacity of Shoshonite is 0.79 kJ/Kg K and that of Jaspillite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Jaspillite is heat resistant, impact resistant, wear resistant.
