Chemical Composition of the Mantle [PDF]
The composition of primitive mantle (54 elements) is estimated by a mass balance approach that does not make a priori assignments of basalt:peridotite ratios or LIL contents of these components.

The formation of ore mineral deposits on the Moon: A feasibility study [PDF]
Most of the ore deposits on Earth are the direct result of formation by hydrothermal solutions. Analogous mineral concentrations do not occur on the Moon, however, because of the absence of water.

Platinum-group element contents of Karelian kimberlites: implications for the PGE budget of the sub-continental lithospheric mantle [PDF]
We present high-precision isotope dilution data for Os, Ir, Ru, Pt, Pd and Re in Group I and Group II kimberlites from the Karelian craton, as well as 2 samples of the Premier Group I kimberlite pipe from the Kaapvaal craton. The samples have, on average,

Mapping curie point depth of the west African Craton from satellite magnetic data and its implication for diamond exploration [PDF]
The main objective of this work is to map the Curie depth of the West African Craton (WAC) using satellite magnetic data with the aim to provide first order evaluation, within this vast territory, for the spatial association between Curie-depth surface ...

About primary diamondiferousness of ancient platforms
As a result of carried out research and summary of the materials on specific features of diamonds, on the example of the Siberian platform, conclusions were made that indications exist at all levels of their location: from kimberlite – provinces, sub ...
