Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / ˈ b æ s ɔː l t, ˈ b æ s əl t /) is a mafic extrusive igneous rock formed from the rapid cooling of magnesiumrich and ironrich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content ...
Cobalt (Co) is a metal used in numerous diverse commercial, industrial, and military applications, many of which are strategic and critical. On a global basis, the leading use of cobalt is in rechargeable battery electrodes. Superalloys, which are used to make parts for gas turbine engines, are another major use for cobalt. Cobalt is also used to make airbags in

Dec 01, 2018· At first, we tried to use the global data to find out if there are differences between the three oceans MORB. The results show that some previous discriminant diagrams do not apply to all the global data of MORB (Wang et al., 2016, Chen et al., 2017).Then we examined almost all kinds of tectonic background of basalt (such as the IAB, OIB, CFB, BAB, CRB, etc.), and find the results of the ...
Associated with the basalt are poorly consolidated tuffs which occur beneath the lowermost and between the some of the succeeding flows. Considerable deposits do exist, particularly at and near the south end of the occurrence of gravels, but exposure are insuffient to allow of accurate determination of character and distribution of these deposits.

The largely buried Yabakei caldera (also known as the Shishimuta caldera), a member of the Hohi Volcanic Zone, was the source of two major Pleistocene explosive eruptions producing the dacitic Yabakei ( Ma) and Im ( Ma) pyroclastic flows (Hayashida et al., 1996; Kamata, 1989). The Yabakei pyroclastics take the form of densely welded tuffs, originally more than 110 km3 in total ...
These materials which include some rare earth elements and are often called critical materials are essential to the clean energy economy and are at risk for supply disruptions. This map shows countries with significant supplies of rare earth elements, and existing mines, deposits.
