Research On Geological Characteristics And Genesis Of The Xuanlinghou Molybdenum Deposit In Liaoning Province

The Xuanlinghou molybdenum deposit is located in the western of theXuanlinghou-Saima multi-metal ore-forming belt in the northern part of the Liaodongrift. The tectonic is belonged to the northern margin of the north China platform，whichis situated in the intersection of Jiao-Liao platform uprise Taizi River-Hun Jiangplatform subside and Yingkou-Kuandian platform uplift. The area is rich in mineralresources whice is our country multi-metal important metallogenic and producing area，and has a lot of prospecting potential.The geological feature and ore genesis of Xuanlinghou Mo deposit in Liaoningprovince had been studied detailedly through the theories of deposit，mineralogy of oredeposit，and techniques of petrology，petrochemistry，geochemistry etc．This researchhave a prospecting practice at the mine area what basically find out the geologicalcharacteristics of the research area，such as stratigraphic，lithology，structural，magmaticrocks and related mineralization characteristics. And unifies the mining areapetrochemistry，the trace element and compares with the research and analysis on thenorthern margin of the north China platform Mo（Cu） ore-forming belt， discusses thehome court to mineralize，the material to originate，the ore deposit origin，to establishthe mineralization model and to carry on the mineralization forecast．The home court molybdenum mineralization is mainly occurs in the Paleoproterozoicporphyritic mixed granite structural fissure. The molybdenum mineralization is relatedto the Late Jurassic Baishuisi granite invasion.The wallrock alteration with themineralization is silicification，potassic and sericitize.The mineralization principally isthe veinlet disseminated type，the mineralization is primarily by the fissure filling，andthe deposit has the same characteristics with the porphyry deposit type．The favorablearea for ore-hunting is in the outside contact zone between the Late Jurassic granite，Paleoproterozoic mixed granite and Liaohe group strata． There would be a goodprospecting future．...
