Laterite has commonly been referred to as a soil type as well as being a rock type. This, and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering), has led to calls for the term to be abandoned altogether.
Red laterite soils in Tamil Nadu, Andhra Pradesh and Kerala are more suitable for crops like cashew nut. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. The name "Laterite" is derived from the Latin word "later" which means a brick. Its red colour is due to ...
The following is a list of rock types recognized by geologists.There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock.
Saprolite is not as weathered as laterite; there is a continuum from the upper layer of saprolite to laterite. Saprolite (from Greek σαπρος (sapros) = putrid + λιθος (lithos) = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite.
Thus, typically, nickel laterite ore deposits contain many billions of dollars of in-situ value of contained metal. [citation needed] Ore deposits of this type are restricted to the weathering mantle developed above ultramafic rocks. [4] As such they tend to be tabular, flat and really large, covering many square kilometres of the Earth's surface.
The Khoai can only support certain types of plants. It is a very poor soil for most types of agriculture practiced in the areas in which it is found. Yet often, a khoai maybe situated adjacent to a naturally forested area. Although a large area in Birbhum is covered by laterite, the areas where the laterite is exposed is termed as Khoai.
The term lunar soil is often used interchangeably with "lunar regolith" but typically refers to the finer fraction of regolith, that which is composed of grains one centimetre in diameter or less. Some have argued that the term "soil" is not correct in reference to the Moon because soil is defined as having organic content, whereas the Moon has ...
