Spinifex texture This komatiite sample displays the characteristic "spinifex texture" defined by extremely acicular olivine phenocrysts--probably a sign of rapid crystallization from a significantly-undercooled magma. The texture is named after a type of grass which grows in South Africa in the region where komatiites were first discovered. |
