Coal is a sedimentary rock formed over millions of years from compressed plants Inorganic detrital rocks, on the other hand, are formed from broken up pieces of other rocks, not from living things These rocks are often called clastic sedimentary rocks One of the bestknown clastic sedimentary rocks is sandstonematrix Usually bluegray to gay in color entirely composed of abraded and rounded shell "hash" Contains little or no matrix White tð tan in color Spherical, very wellsorted grains with concentric layers (ooids) white to beige to grey in color Very finegrained, white to gray, limestone devoid of obvious fossils Variable hardness (H = I to 3) Fines with acidSedimentary Rock Classification ChartChert is a hard and compact sedimentary rock, consisting dominantly of very small quartz crystals It is a common rock type which occurs mostly in carbonate rocks either in nodular form or in layers (bedded chert) Flint on the coast at Stevns Klint in DenmarkChert Sedimentary Rocks Sandatlas

Sedimentary Rocks Sediment is deposited in a number of ways including movement by water, air, gravity or other erosional agents, and by deposition in place through chemical and biological processes Hardening of this material results in sedimentary rock Property Definition How to Evaluate Clastic Obvious pieces of rock Get Price Rocks in the Field Index University of Blue Sedimentary Rocks Bluestone is a colloquial term that usually refers to sedimentary rocks like sandstone or limestone that appear bluegray in color the most common types of bluestone consist of sediments that underwent millions of years of compression to become stone this attractive stone commonly serves as a basic building material for homes and businessesBlue Sedimentary Rocks nieuwvelserduinnlRounded rock and rmneral fragments, usually a finer matrix Angular rock and mineral fragments, usually in a finer sand Rounded quartz grains, well sorted Color variable depending upon the type of cement May contain sedimentary structures Red: iron oxide cement; white: quartz cement; yellow: limonite cement etc Rounded grains of quartz and other minerals "salt pepper Sedimentary Rock Classification Chart

Sedimentary Rocks Sedimentary rocks form from the accumulation of sediment at earth’s surface Most sedimentary rocks are layered Sedimentary rocks can form from grains of preexisting rocks (detritus), from chemical processes, or from organic processes They are classified based on their texture and composition Topics: 1Bluestone is a cultural or commercial name for a number of dimension or building stone varieties, including: basalt in Victoria, Australia, and in New Zealand; bluestone from Europe including the largest European bluestone quarry in Hochberg, Germany; dolerites in Tasmania, Australia; and in Britain (including Stonehenge); feldspathic sandstone in the US and CanadaBluestone WikipediaComposition of Sedimentary Rocks Types of Sedimentary Rocks There are three main types of sedimentary rocks that differ based on their composition and process of formation 1 Clastic Sedimentary Rocks (also called detrital sedimentary rocks) Mechanical weathering physically splits or breaks previously formed rocks into smaller fragments called clasts These clasts Composition of Sedimentary Rocks – Laboratory Manual for
