RIFTING STRUCTURES AND LAMPROITE MAGMATISM
Russian Geology and Geophysics, 1991Among well-known alkaline rocks of complicated volcano-plutonic complex, lamproites were recently recognized on the Aldan Crystalline Shield. In chemistry and mineralogical composition they either belong to lamproites of the orendite series or are close to lamprophyres and alkaline picrites described earlier as kimberlites or kimberlite-like formations

Abstract Suprasolidus phase relations at pressures from 4 to 7 GPa and temperatures from 1000 to 1700°C have been determined experimentally for a sanidine phlogopite lamproite from North Table Mountain, Leucite Hills, Wyoming. The lamproite is silica rich and has been postulated to be representative of the magmas which were parental ...
