Аbout use of ancient weathering crusts formation during diamond-prospecting works
Complex research of Late Devonian – Early Carboniferous and Middle-Late Triassic weathering crusts on various rocks (terrigenous-carbonate formations, dolerites, tuffs, tuffaceous formations and kimberlites) indicated that in conditions of warm and humid

Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Mineralogy of garnets from the Jubileinaya kimberlite pipe and Ottorzhenets kimberlite body
The article presents results of a study of the chemical composition of garnet xenocry-stals from a concentrate of the heavy fraction of kimberlites from the Yubileinaya pipe and Ottorzhenets kimberlite body. Samples from porphyry kimberlites and autolithic kimberlite breccias were taken for analysis from the Yubileinaya pipe.

ABSTRACT Sierra Leone's land governance reform policies are often based on the neoliberal assumption that market growth, gender equality and women's empowerment are mutually compatible objectives. Contrary to this assumption, this article argues that while market‐oriented reforms can help to destabilize legal and cultural norms that are discriminatory ...

Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...
