Abiotic resources are obtained from the non-living and non-organic material. Some of the resources, like water and air, are renewable. Other resources like minerals are non-renewable and exhaustible because they cannot be regenerated. Minerals have many categories like metallic, non-metallic and minor minerals.
The Mines and Minerals (Regulation and Development) Act (1957) is an Act of the Parliament of India enacted to regulate the mining sector in India. It was amended in 2015 and 2016. This act forms the basic framework of mining regulation in India. [1] This act is applicable to all minerals except minor minerals and atomic minerals.
Laterite is a class of materials which contain significant amounts of aluminium and iron. [22] They can form clays able to hold many minerals within them. [ 22 ] The weathering of rocks by leaching and oxidising conditions results in the formation of clay-like [ 22 ] minerals such as goethite , lepidocrocite , and hematite . [ 22 ]
Mineral physics is the science of materials that compose the interior of planets, particularly the Earth. It overlaps with petrophysics , which focuses on whole-rock properties. It provides information that allows interpretation of surface measurements of seismic waves , gravity anomalies , geomagnetic fields and electromagnetic fields in terms ...

Renamed first as ‘Raw Materials Division’ and then as ‘Atomic Minerals Division’ in 1958, it was shifted to Hyderabad in 1974. [1] On 29 July 1998 it underwent the latest name change as 'Atomic Minerals Directorate for Exploration and Research' to assert its status as a premier geological exploration and research organisation.
The mineral composition of manganese-bearing minerals is dependent on how the nodules are formed; sedimentary nodules, which have a lower Mn 2+ content than diagenetic, are dominated by Fe-vernadite, Mn-feroxyhyte, and asbolane-buserite while diagenetic nodules are dominated by buserite I, birnessite, todorokite, and asbolane-buserite.

Mineral Reserves are subdivided in order of increasing confidence into Probable Mineral Reserves or Proved Mineral Reserves. A Probable Mineral Reserve is the economically mineable part of an Indicated Mineral Resource, and in some circumstances, a Measured Mineral Resources. It includes diluting material and allowances for losses which may ...
