Sep 1, 2001 · Grain size varies from. fine crystalline gypsum silt, typical of. ... The gypsum is thought to have originally formed when Lake Bungunnia began to dry up at about 600 000 years BP, and fragmented ... This results in bedding showing a decrease in grain size from the bottom of the bed to the top of the bed. Sediment added as a pulse of turbid water. As pulse wanes, water loses velocity and sediments settle. Coarsest material settles first, medium next, then fine. Multiple graded-bed sequences called turbidites (see figure 7.16 in your text).A difference in grain-size distribution, with a coarser and highly sorted size distribution in B-type gypsum. A difference in the features of the fine layers (thicker and mainly composed of equigranular minerals in A-type and very thin films of phyllosilicate minerals in B-type). A difference in gypsum content, that is lower in the B-type gypsum.An immature clastic rock has well-sorted, resistant grains. . All of the possible answers for this question are correct. Pieces of broken rock produced by physical weathering are collectively called clasts or detritus. Contrary to answer a, conglomerates are made up of various grain sizes.

Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water.Silt forms fine-grained siltstone, with fragments between 1/16 mm and 1/256 mm. Anything less than 1/256 mm results in either claystone or mudstone. Two types of mudstone are shale and argillite, which is shale that has undergone very low-grade metamorphism.The climate of the source area can also influence composition. Most breccias are a mix of rock fragments and mineral grains. The type of rock that the fragments were produced from is often used as an adjective when referring to the rock.
