...A. Indares; J. Martignole Abstract Temperature estimates obtained with various biotite-garnet thermometers are inconsistent in granulite facies rocks. Although the inconsistency lies partly in the lack of definition of equilibrium criteria, it still remains after rigorous selection of analyzed...

... Although granulite facies rocks are present in zones of orogenesis ranging in age from 300 to 3,000 m.y. in Africa, only two distinct ages of granulite facies metamorphism, at about 1,200 and 3,000 m.y., have thus far been recognized. Granulite facies suites in regions of orogenesis of other...

...T. W. Vennemann Abstract For the granulite facies rocks of the Southern Marginal Zone (SMZ) of the Limpopo Belt, minimum peak metamorphic temperatures of 800+ or -70 degrees C are estimated by quartz-garnet oxygen isotope thermometry. These temperatures are in agreement with temperatures expected...

... continental crust. If this idea is correct, then granulite-facies rocks, which are the sources for crustally derived melt, and comprise the residual material left behind after melt loss, should have depleted heat production rates with respect to crustally derived granites. However, K–U–Th measurements from...

A scenario involving a tourmaline-enriched lateritic precursor affected by dehydration melting is our preferred explanation for the origin of the Fe-Al-B-rich lenses at the five localities.
