16.2" Polished Rainforest Jasper (Rhyolite) Slab - Australia

WebbRhyolite is an extrusive igneous rock, formed from magma rich in silica that is extruded from a volcanic vent to cool quickly on the surface rather than slowly in the subsurface. It is generally light in color due to its low content of mafic minerals, and it is typically very fine-grained (aphanitic) or glassy. [5] WebbRhyolite is of volcanic origin. It polishes well with diamond, tin oxide and a quick final polish with Zam (Green Rouge) will produce a higher polish.

It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. … Visa mer Due to their high content of silica and low iron and magnesium contents, rhyolitic magmas form highly viscous lavas. As a result, many eruptions of rhyolite are highly explosive, and … Visa mer Rhyolite is common along convergent plate boundaries, where a slab of oceanic lithosphere is being subducted into the Earth's mantle beneath … Visa mer In North American pre-historic times, rhyolite was quarried extensively in what is now eastern Pennsylvania. Among the leading quarries was … Visa mer Rhyolite magmas can be produced by igneous differentiation of a more mafic (silica-poor) magma, through fractional crystallization or by assimilation of melted crustal rock ( Visa mer The name rhyolite was introduced into geology in 1860 by the German traveler and geologist Ferdinand von Richthofen from the Greek word rhýax ("a stream of lava") and the rock name suffix "-lite".
