the massive sulphide deposit at kantienpan cu-zn mine is hosted by volcano sedimentary succession known as the areachap group, in the eastern part of namaqua metamorphic province, south africa. the deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted massive sulphide (vhms) depo...

The sandstone-hosted Beverley uranium deposit is located in terrestrial sediments in the Lake Frome basin in the North Flinders Ranges, South Australia. The deposit is 13 km from the U-rich Mesoproterozoic basement of the Mount Painter inlier, which is being uplifted 100 to 200 m above the basin by neotectonic activity that probably initiated in the early Pliocene. The mineralization was deposi...

The Dongpuzi deposit is an epithermal gold located in the southern margin of Shaozihe volcanic fault basin Liaodong Peninsula. On basis fluid inclusion and C–H–O–S–Pb isotope data, a metallogenic model established for deposit. mineralization at has experienced quartz–pyrite (I), quartz–sulfide (II), quartz–calcite (III) stages. quartz from ore stage II liquid-dominated aqueous inclusions, which...

Eastern Indonesia, including the island of Halmahera, is a region with high mineral potential, particularly Ni-Co, Au-Cu, and Ag ores, which are globally important critical source raw materials (CRMs). The research was conducted within framework scientific cooperation between Faculty Geology, University Warsaw (Poland), PT Halmahera Resources Percasa Ltd. (Jakarta, Indonesia) Between years 2009...

BACKGROUND In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. OBJECTIVES Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify additional ...
