Marble is a metamorphic rock consisting of carbonate minerals that recrystallize under the influence of heat, pressure and aqueous solutions, most commonly calcite (CaCO3) or dolomite (CO3)2 and has a crystalline texture of varying thickness. Marble is typically not foliated (layered), although there are exceptions. About 10-15% of the sedimentary rocks on Earth are composed of limestone. 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)
