2013-12-27 The gold-bearing quartz veins and their behavior in weathering profiles of laterites are widely studied [3,4]. However, many vast tropical areas are widely covered by a lateritic weathering mantle. In tropical regions, weath- ering profiles are thick and thus conceal alterations in the bedrock . Also, the lateritic profiles usually consist of
2014-1-12 Even though certain types of quartz veins do never bear any quartz crystals, ... Shiny pyrite cubes are included in this vein quartz from an old gold mine dump at Arbaz, Valle de Aosta, Italy. 10mm 2240x1434 386kb This is a polished section of a piece of a quartz vein with yellow chalcopyrite and pyrite crystals in several lines that
2004-10-24 Gold is commonly found in placer deposits in rivers, quartz veins, disseminated as micron-sized flakes, and in volcanic rocks associated with calderas. Placer gold was the likely source of most pre-Columbian gold because it was the easiest to mine and required little or no preparation before crafting. Goldworking is more

2014-2-9 bonate veins on the south-east coast of the island (Figs 1, 2) were sampled during boat-supported field work. Massive sul- phide mineral deposits (Fe-Zn-Pb) were located in the centre of brecciated quartz-carbonate vein systems at several places along the south and south-east coast of the island, and gold anomalies mainly associated
