| Abstract: | The silver deposit in Baolongnangou-Laoaogou mineralization belt of Keyouqian Banner,Inner Mongolia,controlled by the fracture,is hosted in altered rocks of the Upper Jurassic Manketou’ebo Formation and Jurassic granite body.The main alterations are potassium alteration,tourmalinization,sericitization,silication,chloritization,and epidotization.The ore minerals are argentite,galenite,sogakerutem,arsebiotrutem,molybdenite,bismuthinite,pyrite,chalcopyrite,magmetite,limonite,etc.According to the study on geological fetrues,mineralizaiton alteration,rock features,mineral components,texture and structure,and relations of mineralization and alteration,we found that the siver depodit is a veined mesothermal-epithermal deposit. |
