Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

Stone (1751 Kent cricketer)

Stone (first name and dates unknown) was an English cricketer who played in major cricket matches for Kent in 1751.

Career

Stone played in two major matches in 1751 for Kent against the All-England Eleven. On 20 and 21 May, he was a member of the Kent team that lost by 9 runs at the Artillery Ground. A return match was arranged at the same venue on 22 May and All-England won by an innings and 9 runs, with Stone again a member of the Kent team.

Stone was also named in two single wicket "fives" matches that were held on 3 and 5 June at the Artillery Ground. In both games, he played for Kent against Surrey, Kent winning each time.

Stone is only recorded on those four occasions and it is not known if he played regularly in earlier and later seasons. Players were rarely mentioned by name in contemporary reports and there are no other known references to Stone.

List of Caribbean membranophones

This is a list of membranophones used in the Caribbean music area, including the islands of the Caribbean Sea, as well as the musics of Guyana, Suriname, French Guiana, Belize, Garifuna music, and Bermuda. It only includes membranophones that are indigenous to the local music area or are a vital and long-standing part of local culture. It does not include membranophones that are, for example, a part of Western style orchestras, nor does it include trap sets and other common membranophones used in popular music recordings of many genres across the world. Almost all membranophones are drums and percussion instruments.

The Hornbostel-Sachs number is given after each instrument.
