Sedimentary Rocks: Meaning, Composition and Weathering

Most of the sedimentary rocks are formed by compression and cementation of sediments. These sediments mostly are fragments of rocks and may range in size from tiny particles like silt and clay to larger particles like sand and pebbles. Another process of formation of sedimentary rocks is by evaporation of sea water.

11 Main Features of Sedimentary Rocks | Geology

The colour of hematite is so dominant that a very small amount of it will colour the rock a faint shade of red. By combining with water some of the hematite will form iron oxide limonite (Fe 2 O 2 O) which produces the yellow and brown colours of the weathered rocks. Mixtures of hematite and limonite produce orange and purple colour.

Oolite Sedimentary Rocks

Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.

Sedimentary Mineral Deposits Mineral Processing Metallurgy

Mechanical Deposition of Sedimentary Mineral Deposits In some cases, the ore mineral, on account of its resistance to weathering and its hardness, survived the destruction of many of the rock minerals; and, during sedimentation, on account of its weight, it was sorted out from the fragments of quartz and other resistant minerals. Thus, the oremineral was deposited, without being chemically ...

Residual and Sedimentary Soil. According to its geologic origin, soil is either residual or sedimentary. Residual soil is formed in place. That is, it is a result of the weathering, disintegration, and decomposition of the parent material. Sedimentary soil is formed from materials that have been moved from where they originated by either wind ...

What are the Characteristics of Sedimentary Rocks?

Feb 23, 2018· Characteristics of Sedimentary Rocks The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral. ...
