The ore bodies are preserved in fractured Ordovician sedimentary clastic rocks The gold‐bearing minerals occur dominantly in sulfide‐quartz veins Fluid inclusion analysis shows that the Changan gold ore deposit is characterized by epithermal gold mineralization at temperatures between 200°C and 280°C at a shallow crustal levelView Detail

The salinity and temperature of oreforming fluids have wide ranges Salinities of some oreforming fluids are lower than sea water whereas those in fluids forming porphyry deposits can reach 80 wt NaCl Heinrich 2007The salinity and temperature of most hydrothermal fluid decrease during the latestages of ore formation suggesting either the attenuation of heat and fluid source or theView Detail
Mesothermal gold deposits form half way up through the rise of the melt from the deep crust to the surface usually at a depth of less than 10 km but greater than 1 km temperatures at these depths are generally somewhere between 450 degrees and 250 degrees Celsius The term mesothermal veins is really a sack term referring simply to the depth formation It pays little attention to the originView Detail
Jul 27 2019 · Minerals and rocks change under high pressure For instance the common mantle mineral olivine changes to different crystal forms at depths around 410 kilometers and again at 660 kilometers We study the behavior of minerals under mantle conditions with two methods computer models based on the equations of mineral physics and laboratoryView Detail
21 Where do the toxic gases and leachates come from that are the result of mining not processing for gold A sulfur compounds in the ore B chlorine compounds in the ore C carbon compounds in the ore D cyanide used in the operation of mining for the gold E heavy metals used in the operation of mining for the goldView Detail
