âOhio never left,â says venture capitalist Mark Kvamme, whose Columbus-based Drive Capital fund raised the second largest inaugural round of venture capital ever in 2013 ($250 million) betting on the Midwestâs frothing start-up ecosystem. âPeople just stopped paying attention.â.
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.or example, limestone is a sedimentary rock composed almost entirely of the mineral calcite. Other rocks contain many minerals, and the specific minerals in a rock can vary widely. Some minerals, like quartz, mica or feldspar are common, while others have been found in only one or two locations worldwide.
Minerals are inorganic compounds -- ones not based on carbon and hydrogen -- and are smaller particles that come mostly from natural geological processes. They have a simple chemical structure compared to vitamins, which can have large and complex chemical structures.
