Abstract Unusual hydrothermal native As-sulfide ± Ag arsenide antimonide sulfosalt ore shoots and their co-genetic sulfide-fluorite-barite-quartz host veins, which are common in the region whole Central Europe, were investigated at three localities Schwarzwald, SW Germany, to understand physico-chemical processes governing change from a normal (= common) an exceptional shoot regime. Based on fl...

Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of Jurassic age. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5 ± 2 Ma. Four trends of faults...

the gandy gold-base metal deposit is located in tertiary torud-chahshirin volcano-plutonic range, north of central iran. various styles of gold mineralization occur throughout the range. mineralization at gandy occurs in close spatial relation with rhyolitic domes in a caldera setting in a series of narrow brecciated veins. two mineralogically and spatially different argillic alterations have a...

The Elatsite–Chelopech ore field in the northern part of Panagyurishte district Central Bulgaria comprises numerous spatially associated porphyry copper and epithermal gold deposits prospects. In addition to mineralization alteration features, trace elements, lead sulfur isotope signatures sulfide minerals from copper, base metal gold-base deposits/prospects have been studied. LA-ICP-MS analyse...
