辽北清原地区典型金矿地质特征、成因类型及成矿规律
Geological characteristics,genetic types and metallogenic regularity of typical gold deposits in Qingyuan area of the northern Liaoning Province
摘要
Abstract
The gold resources in Qingyuan area of the northern Liaoning Province are abundant,but the genetic types and metallogenetic law of gold deposits in this area have not been systematically discussed.The spatial dis-tribution,ore-bearing horizon,controlling structural types,mineralization alteration,and the isotope geochemi-cal characteristics of typical gold deposits were collected to summarize the mineralization regularity of gold depos-its.The results showed that gold deposits in Qingyuan area of the northern Liaoning Province mainly occurred in Shipengzi Formation and Hongtoushan Formation of Qingyuan Group,while a small amount of gold deposits oc-curred in Archean and Mesozoic granitic rock.The ore-controlling structures were mainly inverted syncline struc-ture,fault structure and ductile shear zone in Archean granite-greenstone terrane.The isotope geochemical char-acteristics showed that the ore-forming fluids in Qingyuan area were derived from seawater,metamorphic hydro-thermal and magmatic hydrothermal fluids,respectively.The ore-forming materials came from deep source mag-ma or mixture of magma and strata.The genesis types of gold deposits could be divided into volcano-associated massive sulfide(VMS)type,magmatic hydrothermal type,and metamorphic hydrothermal type.Three IV gold sub-metallogenic belts,six mineralization prospect areas and two mineralization series have been delineated ac-cording to the controlling conditions,genesis types,and regional anomaly distribution characteristics.The study achievements could supply scientific and theoretical basis support for the gold exploration in the northern Liaoning Province.关键词
