Comments on: ‘Petrogenesis of Proterozoic Lamproites and Kimberlites from the Cuddapah Basin and Dharwar Craton, Southern India’
Kimberlites intrude the late Archaean eastern Dharwar Craton in two spatially separate fields ( 150 km apart, near Mahbubnagar in the north and Anantapur in the south) to the west of the Proterozoic Cuddapah Basin in southern India. Two lamproite bodies intrude the thick Cuddapah Basin sediments near Chelima and Zangamarajupalle, and a third occurs just outside the present NE margin of the basi...

Widespread Archean basement beneath the Yangtze craton
The age distribution of the crust is a fundamental parameter in modeling continental evolution and the rate of crustal accretion through Earth’s history, but this is usually estimated from surface exposures. The exposed Yangtze craton in eastern China consists mainly of Proterozoic rocks with rare Archean outcrops. However, the U-Pb ages and Hf isotope systematics of xenocrystic zircons brought...
متن کاملProvenance and Tectonic Setting of Late Archaean Greywackes from Dharwar Craton: Karnataka, India
Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...
متن کاملThe role of serpentine in preferential craton formation in the late Archean by lithosphere underthrusting
Cratons form the cores of continents and were formed within a narrow window of time (2.5–3.2 Gy ago), the majority having remained stable ever since. Petrologic evidence suggests that the thick mantle roots underlying cratons were built by underthrusting of oceanic and arc lithosphere, but paradoxically this requires that the building blocks of cratons are weak even though cratons must have bee...
