In geochemistry, compatibility is a measure of how readily a particular trace element substitutes for a major element within a mineral. Compatibility of an ion is controlled by two things: its valence and its ionic radius. [1] Both must approximate those of the major element for the trace element to be compatible in the mineral.
Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.

Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals and intermetallic elements, semi-metals and non-metals. This group also includes natural alloys, phosphides, silicides, nitrides and carbides.

Armalcolite is a titanium-rich mineral that falls under the magnesianferropseudobrookite mineral group with Fe 2+ Ti 2 O 5 and MgTi 2 O 5 as end members. [8] Due to having octahedral symmetry, armalcolite has solid solution (cation substitution) between multiple elements Fe 2+ , Fe 3+ , Mg, Al, and Ti; this is because of their similarities in ...
[2] [3] This infers that the rock is a poor heat conductor, which the maximum temperature experienced by the rock as well as its temperature change are insensitive to erosion rate. [2] Therefore, both the evidence of the maximum pressures and temperatures experienced by the buried layers can be imprinted in the underlying metamorphic rocks. [ 2 ]
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
