As distribution of clay minerals in modern oceans seems to be controlled by contemporary
climates, marine clays in ancient deposits have been widely used to reconstruct …

Supergene lateritic deposits have played an important role in the global mineral resource
economy for over 50 years, with lateritic Al, Fe, Ni, and Au deposits having a significant input …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

The BIF-hosted iron ore system represents the world's largest and highest grade iron ore
districts and deposits. BIF, the precursor to low-and high-grade BIF hosted iron ore, consists …

Nine samples of supergene goethite (FeOOH) from Brazil and Australia were selected to test
the suitability of this mineral for (U-Th)/He dating. Measured He ages ranged from 61 to 8 Ma …

▪ Abstract Recent developments in the application of K-Ar and 40Ar/39Ar dating of
continental weathering process demonstrate the method's suitability for dating minerals …

Geochemical and mineralogical investigations, including measurements of major and trace
elements, Sr isotope ratios, and 238U-234U-230Th activity ratios, were made on an old …

channel iron deposit (CID), Hamersley Province, Western Australia, reveals a history of …

Abstract The Bodaibo District (the Irkutsk Region of Russia) is a world-class gold-mining
subprovince comprising a total of 13 large-and medium-scale black-shale-hosted orogenic …

Chemical weathering and mechanical erosion are first‐order processes of long‐term tropical
morphogenesis, which is still poorly deciphered for lack of time constraints. We address this …
