It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks. They share the same color ranges of white-to-gray and white-to-light brown (although other colors such as red, green, and black are ...

But, they are important rocks because they are the most abundant sedimentary rocks, making up over 65% all sedimentary rocks, are likely the source rocks for petroleum and natural gas, and are sometimes valuable ore deposits. In addition, the mudrocks are the protoliths (precursor rock) for aluminous metamorphic rocks, Classification-Sandstone: Sandstone is a sedimentary rock composed of sand-sized grains of minerals, rocks, or organic material. It also has a high porosity, which makes it ideal for storing fluids. It is well known for its use in construction and as a building material.-Limestone: Limestone is a sedimentary rock composed of calcium carbonate. It has a high ... The White House of the USA is made of a sedimentary rock called sandstone. The White House (shown in the Figure above ) is the official home and workplace of the President of the United States of America.

Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg (CO3)2. It commonly occurs in association with limestone and shares many of the same properties, but reacts only weakly with acid. Dolomite often has a sugary texture and is typically off-white to gray in color.Other chemical sedimentary rocks. Other chemical sedimentary rocks include: banded-iron formations; ironstones; cherts; evaporites; silcretes; calcretes; Zebra rock. Zebra rock or Zebra stone is a distinctive reddish-brown and white banded claystone from the Ord River area of Western Australia where it forms discontinuous lenses within a Late ... The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. ….

Light-colored, white, or yellow rocks can be composed mostly of quartz, plagioclase, or calcite. Dark-colored, black, rocks can be made of pyroxene, biotite, or chromite. The red color of the rock is explained by iron oxides. All rocks are made of minerals.

Chert 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 Denmark.

Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores.
