Upper crust of the Pilbara Craton, Australia; 3D geometry of a granite/greenstone terrain
The Pilbara Craton in Northwest Australia is a 600×550 km region of early-mid Archaean granite/greenstone terrain, dominated by granite domes, and in part covered by younger rocks. Gravity and magnetic anomalies are used to map the granite/greenstone surface under cover, and infer the depth extent of the granite/greenstone structures. A published seismic refraction interpretation gives a two la...
متن کاملWidespread 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 کاملPlants used as abortifacients in the Sangmelima region of Southern Cameroon.
Twenty species from 16 plant families used to induce abortion in the Sangmelima region (South Province of Cameroon) are reported with local names, modes of uses and their side effects, if known, with a discussion on pharmacological effect based on published experimental literature.
متن کاملMetamorphism of basement rocks in the Central Zone of the North China Craton: implications for Paleoproterozoic tectonic evolution
Lithological, structural, metamorphic and geochronological data for the North China Craton enable its division into the Western and Eastern Blocks of Archean to Paleoproterozoic age separated by a north–south trending Paleoproterozoic orogenic belt: the Central Zone. The Central Zone is divisible into a series of lowto medium-grade granite–greenstone belts and high-grade metamorphic terrains co...
متن کاملGeomorphic and structural assessment of active tectonics in NW Alborz
Alborz Mountains is a region of active deformation within Arabia-Eurasia collision zone. The study fault system in western Alborz comprises abundant evidence of active faulting accompanied by occurrence of historical earthquakes. Active tectonics of Manjil-Rudbar fault zone whose movement caused destructive 1990 Manjil-Rudbar earthquake was concentrated in this article through geomorphic and st...
