Do minerals determine the texture of a rock

WebThe texture of the plutonic rock that forms as a result is determined by the chemical make-up of the magma as well as the rate at which it crystallizes and cools. Large phenocrysts of the first mineral to crystallize can be found strewn about the rock, but in general, the plutonic rock's texture will be a mixture of all three minerals. WebCommon minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt, limestone, and sandstone. Learn more: Collecting Rocks USGS National Geologic Map Database (rock/geology maps)
