mining technology of gold bearing quartz vein in china

Genesis and mineralization of gold-bearing quartz

Gold-bearing quartz veins of the Taihua Group consisting of Archean metavolcanic rocks are a main gold deposit type in the Xiao Qinling area, one of the three biggest gold production areas in China. The quartz veins experienced strong alteration characterized by a typical mesothermal hydrothermal altered mineral assemblage. The grade of gold is affected by the contents of sulphides, e.g ...

U‐Pb SHRIMP Dating of Zircon from Quartz Veins of

Abstract The Yangshan gold deposit is a super‐large fine‐grained disseminated gold deposit located in southern Gansu Province. Its metallogenic age has been determined by using the cathodoluminescence image and ion probe U‐Pb dating techniques. It is found that zircons from quartz veinlet of the fine‐grained disseminated gold ore show characters of magmatic origin with prism ...
