Abstract Paragenetic associations of tetrahedrite-(Zn) and sphalerite are distinguished in the Teremki gold-ore deposit. The chemical composition coexisting minerals this association is determined. Sb/(Sb + As) Fe/(Fe Zn) ratios vary from 0.66 to 0.97 0.28 0.40, respectively. A negative correlation was established between ratios. Contents Fe change 0.88 1.43 wt % (1.5–2.5 mol FeS). Temperature ...

We evaluated the significance of iron and manganese content in sphalerite as a tool for distinguishing between low-sulfidation intermediate-sulfidation epithermal deposits on basis new previously published electron probe microanalyses data Roșia Montană ore deposit available microchemical from Neogene located Apuseni Mountains Baia Mare region, Romania. Two compositional trends Fe vs. Mn were d...

The Suyoc prospect is an epithermal vein-type mineralization located at the southern part of Mankayan Mineral District, Northern Luzon, Philippines. prospect’s veins are hosted in volcaniclastic rocks and conglomerate, which belong to Late Oligocene Early Miocene Balili Formation Middle Conglomerate, respectively. These classified into three major types: quartz vein, quartz-sulfide quartz-carbo...

Northern Mozambique hosts numerous occurrences of gold mineralization in metamorphic terranes, which are little known because the insufficient studies. In this work, we describe main geological and geochemical characteristics Nanlia Makorongo prospects located Namuno district, northeastern Mozambique. We report mode occurrence gold, petrography mineralogy host rocks ores, fluid inclusion stable...

Abstract The Anarraaq clastic-dominated (CD) Zn-Pb-Ag deposit (Red Dog district, Alaska, USA) has an inferred mineral resource of 19.4 Mt at 14.4% Zn, 4.2% Pb, and 73 g/t Ag is spatially associated with a separate ~1 Gt barite body. This study presents new cross sections petrographic evidence from the area. body, previously shown to have formed in shallow subsurface environment akin methane col...
