Classification of Sedimentary Rocks | Geography
1. Mechanically Formed Sedimentary Rocks: Previously formed rocks are subjected to mechanical or physical disintegration and thus the rocks are broken into fragments of different sizes. These are called fragmental rock materials or clastic materials which become source materials for the formation of clastic sedimentary rocks.

Gypsum
Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.

Gypsum History
In fact, gypsum is a detrital sedimentary rock and can be found soluble in seawater. As water evaporates in parts of the sea, this material (sedimentary rock) can no longer remain soluble, some of which will inevitably become insoluble and precipitate after years of chemical reaction with decaying plants and other minerals.
Gypsum | Physical-Optical Properties, Uses, Occurrence
Gypsum is a not unusual mineral, with thick and good sized evaporite beds in affiliation with sedimentary rocks. Deposits are recognized to occur in strata from as a long way lower back as the Archaean eon. It is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate answers in veins.
Why is gypsum a sedimentary rock? – Wise-Answer
The result is the accumulation of large beds of sedimentary gypsum. Because it is deposited in this environment, it is common for gypsum to be associated with rock salt and sulfur deposits. Is rock gypsum a sedimentary rock? Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.
Types of Sedimentary Rock
Sedimentary rocks form at or near the Earth's surface. Rocks made from particles of eroded sediment are called clastic sedimentary rocks, those made from the remains of living things are called biogenic sedimentary rocks, …
What Are Sedimentary Rocks?
Sedimentary rocks are one of the three great rock classes (along with igneous and metamorphic rocks). ... then gypsum, then halite. The resulting rocks are certain limestones, gypsum rock, and rock salt respectively. These rocks, …

7 Sedimentary Minerals and Sedimentary Rocks – …
The most common sedimentary rocks – including shale, sandstone, and conglomerate – form from siliciclastic sediments. Other kinds of sedimentary rocks consist of carbonates (in limestones), iron oxides and hydroxides (such as hematite or goethite in iron formation), or other minerals. Geologists classify siliciclastic sediments based on grain size.
Rock Gypsum
Rock Gypsum. Rock Gypsum is a sedimentary rock in the class known as chemical sedimentary rocks. It is formed by the evaporative deposition of gypsum from solution. It is commercially very important for the production of plaster of Paris and gypsum wallboard for house construction. Sedimentary Rocks.

Classification of Sedimentary Rocks | Geography
Based on major transporting agents, sedimentary rocks are divided into: 1. Argillaceous, 2. Aeolian and 3. Glacial rocks. (1) Argillaceous rocks are also called as aqueous rocks because these are formed in water areas. Aqueous word has been derived from Latin world 'aqua' which means 'water'.

Understanding Gypsum
Gypsum is soluble and dissolves and moves into the soil rapidly. It dissolves more quickly than limestone after surface application. Gypsum improves water infiltration in soils, reducing runoff and erosion potential. It helps to reduce soil crusting after rainfall or irrigation. Crusted soil can reduce seed emergence and seedling establishment.
