Physical properties
Hardness 6 on Mohs scale, grayish-brown color with dull to sub-vitreous luster, porphyritic texture with distinct plagioclase and biotite/hornblende phenocrysts.
Formation & geological history
Formed from the rapid cooling of intermediate lava with a composition intermediate between trachyte and andesite.
Uses & applications
Used primarily as crushed stone for road construction and aggregate in concrete.
Geological facts
Latite is relatively uncommon compared to basalt or rhyolite and typically erupts from continental arc volcanoes.
Field identification & locations
Identified by its fine-grained aphanitic groundmass containing larger, blocky feldspar phenocrysts; found worldwide in volcanic provinces.
