The Nanling Region in South China hosts numerous W-dominated polymetallic deposits that are related to Mesozoic granites. Although considerable amounts of age data have been obtained, the genetic relationship between granitic magmatism and W minerali

Intracontinental basins that lack obvious compartmentalization and extensional faults may lie inboard of, and have the same timing as, rifted continental margins. Neoproterozoic successions of northwest Laurentia are an example where rift and intraco

SHRIMP U-Pb zircon and titanite age data for granites adjacent to the Gadag greenstone belt (GGB) in the Western Dharwar Craton (WDC), India, establish the occurrence of voluminous ∼2.56 Ga granitic magmatism and indicate the development and evolut

Banded iron formations (BIFs) are chemical sedimentary rocks comprising alternating layers of iron-rich and silica-rich minerals that have been used to infer the composition of the early Precambrian ocean and ancient microbial processes. However, the

Life on Earth is thought to have coevolved with the chemistry of the oceans and atmosphere, and the shift from an anoxic to an oxic world across the Archean-Proterozoic boundary represents a fundamental step in this process. In order to understand th

Siliciclastic supersequences in the Eastern Goldfields Superterrane are remnants of basins that were linear zones of subsidence between intra-terrane faults. Fluvial deposits record proximal to medial braid-plains. Deep-marine canyon and fan deposits

The Penny Dam, Belches, Yilgangi, White Hills, Granny, Royal, Lucky, Brock and Wallaby Supersequences of the Kurnalpi Terrane crop out in synclines that are the erosional remnants of basins that developed as linear zones of subsidence between approxi

The Kalgoorlie Sequence ( 2658 Ma) is a >3000 m-thick succession of volcaniclastic sedimentary rocks and subordinate rhyolite, dacite, andesite and basalt spatially and temporally associated with subvolcanic sills and dykes of rhyolite and dacite, ga

Analysis of the tectonostratigraphic records of Late Archean to Early Paleoproterozoic terranes indicates linkage between global tectonics, changing sea levels and environmental conditions. A Late Archean tectonic cycle started at ~2.78 Ga involving
