Historical work suggests that Mothae has a low average diamond grade of ~ 3 cpht and the economic viability therefore depends on the presence of large, high quality (and thus value) diamonds as does that of the nearby Letseng Diamond by: 5.

Evidence is presented that the inflected palaeogeotherm for northern Lesotho, previously highlighted by Boyd (), Boyd and Nixon (, ), Finnerty and Boyd (, ), is essentially an artifact of the unsatisfactory, over-simplified barometer formulation (based on MacGregor ) employed.

Based on Boyd’s P-T phase-equilibrium studies on the diopside–enstatite miscibility gap, coupled with analytical data on Al 2 O 3 solubility in magnesium-rich enstatite, Joe demonstrated that the compositions of coexisting magnesian pyroxenes and garnets in these rocks could be used to calculate their File Size: 2MB.

Mica nodules from the Dutoitspan and Wesselton mines, Kimberley can be divided into two groups: diopside-phlogopite nodules and potassic richterite-phlogopite nodules. The latter is characterized by the presence of abundant potassic richterite (less than 50% by volume) and large size of the crystals (up to 1 cm in length).

It seems this type nodule is the first by: Books For Lesotho An Adelaide-based non-profit organisation dedicated to developing libraries for the schools of Lesotho.
