Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals.May 31, 2022 · Chalk Characteristics and Properties. Chalk, in both its natural and man-made form, is white in colour and is considered to be a fairly soft solid. Naturally, It comes from the ground where it is found as a porous (can hold water) sedimentary rock. It is a form of limestone and is composed of the mineral calcite. When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. The carbon dioxide causes bubbling during the reaction, which is observed as fizzing. ... Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double …DF2014:Chalk. This article is about an older version of DF. Chalk is a flux stone found in the sedimentary layer. As such, it is worth twice as much as most other stones.

Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts are angular or subangular. ku dick Rock History. Very fine-grained, so deposited in a very low energy environment. 1. Tests of calcitic plankton. 2. Very finely ground shell fragments. Currents alone could not grind the shells this finely. This would require bioerosion - e.g. fish ingesting organisms with carbonate shells, and grinding the carbonate to a fine powder.Chalk is an organically formed sedimentary rock.
