A dense, fine-grained, naturally occurring form of silica (Si02) that fractures conchoidally A variety of chert, the more technical term Most flint is gray, brown, black, or otherwise dark, but nodules and other chunks tend to weather white or change to lighter shades from the surface inward
a river in western Georgia that flows generally south to join the Chattahoochee River at the Florida border where they form the Apalachicola River
A hard, brittle stone, usually a type of chalk or limestone that can be flaked (see below) in any direction and easily shaped Flint occurs naturally in many locations and often formed the material for human tools, until humans learned to work metals Flint was the most common 'stone' of the Stone Age
A microcrystaline silicate rock similar to CHERT, used for the manufacture of flaked stone tools Colour most commonly grey, honey-brown, or black
A flint is a small piece of flint which can be struck with a piece of steel to produce sparks. A city of southeast-central Michigan north-northwest of Detroit. Founded on the site of a fur-trading post established in 1819, it became an automobile-manufacturing center in the early 1900s. Population: 140,761. City (pop., 2000: 124,943), eastern Michigan, U.S. Originally the site of a trading post, the city was laid out in 1836 and became a fur-trading and agricultural centre. Abundant supplies of timber led to the development in 1886 of the Durant-Dort Carriage Co., and by 1900 it was producing more than 100,000 horse-drawn vehicles a year. Some of the companies became suppliers for what would become the General Motors Corp. By the 1950s, the city was second only to Detroit in U.S. automobile manufacturing. The closing of various GM plants in the 1980s and '90s left Flint with a shrinking economy. The GMI Engineering and Management Institute (1919) and the University of Michigan-Flint (1956) are located there
A quartz with a high silica content that produces a conchoidal fracture when chipped It is usually found in association with chalk, limestone, and other rock deposits which contain lime It commonly occurs in small ovoid nodules as well as in larger veins Impure flint is known as chert, which varies widely as to texture, color, grain, and knapping characteristics Pure flint is so hard and even-grained that is use by early man was a vital necessity in producing spear point, dart point, knives and other utilitarian tools Late stone-age man learned that when struck with a high iron content rock, the flint gave off sparks Thus, flint became Iron-Age man's method of producing fire Flint comes in many colors from white to black including gray, tan, brown, olive, blue, and other variants and mottled combinations
