President Trump says he wants to make a deal for minerals from Ukraine in exchange for aid. That followed a long effort by Ukrainian officials to appeal to Mr. Trump’s transactional nature.

For example, a meta-analysis of over 5,500 soil horizons revealed a global correlation between slow carbon turnover dynamics and the presence of fine-grained minerals, notably calcium-bearing ...

Biotite is a common phyllosilicate mineral that contains potassium, magnesium, iron and aluminium. It is sometimes called “iron mica” and is found in granitic rocks, gneisses, and schists. Like other ...

Caprock Mining (CSE: CAPR) says SGS Natural Resources has confirmed the lithium-bearing mineral in samples from the Ackley property in southeast Newfoundland has been confirmed as zinnwaldite. Assays ...

Chen et al. [2023] explore the possibility of stacking the released water in the effective 2D fluidic phase within intercalated crystalline interfaces of phyllosilicate minerals like graphite ...

According to CRISM multispectral data, the exposures of light-toned materials (on small hills and between darker dunes) shows a strong iron-magnesium phyllosilicate (clay) signatures in this area.

Muscovite mica is a common layered phyllosilicate mineral with perfect cleavage planes. These atomically flat surfaces are ideal for studying minerals and clays using scanning probe techniques with ...

Phyllosilicate minerals and Fe/Al oxides have different surface and active absorbing sites, and therefore, their ability to absorb SOC differs. The adsorption of organic matter by Phyllosilicate ...

Characterization of the minerals was carried out mainly by X-ray diffractometry (XRD), which allowed identifying vermiculite and three interstratified phyllosilicate phases. These minerals presented ...
