Geology of a complex kimberlite pipe (K2 pipe, South Africa): insights into conduit processes during explosive ultrabasic eruptions [PDF]
, 2009 K2 is a steep-sided kimberlite pipe with a complex internal geology. Geological mapping, logging of drillcore and petrographic studies indicate that it comprises layered breccias and pyroclastic rocks of various grain sizes, lithic contents and internal ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.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 ...

Geological and structural characteristics of deep-level rock mass of the Udachnaya pipe deposit
Записки Горного института, 2021 For hard rock massifs, structural disturbance is a key indicator of mining structure stability. The presence of intersecting structural elements in the massif reduces rock strength and leads to formation of potential collapse structures.

Development and Change, Volume 57, Issue 2, Page 315-338, March 2026.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 ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.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 ...
