康定-攀枝花地区区域金矿化特征
REGLONAL GOLD MINERALIZATION IN KANGDINGPANZHIHUA REGION
-
摘要: 本文从康定群、区域构造和绿岩带的特征讨论了与金矿化的关系。指出康定群为康定-攀枝花地区主要含金岩系;由泸定-孔玉一带72条断裂带痕金分析结果表明,北北东和北北西向压性、压扭性断裂为含金断裂;康定瓦斯沟-孔玉地区遥感图象中所显示出的近20个环形构造,在其边部和内部常有金矿形成;康滇地轴中段西部绿岩带中各类岩石的含金量普遍较高,可为金矿化提供充足的矿质。文中依据各类金矿床(点)分布特征,将区内金矿化划为康定-泸定等四个成矿区。Abstract: The relation of mineralization wiht Kangding Group,regional regional structures and greenstone belt is discussed.The Kangding Group is the major auriferous rock series.Trace analysis of gold for 72 faults is Luding-Kongyu area ahows NNE- and NNW-trending compression and Compresso-shearing faults being gold-bearing.Gold deposits occur frequantly in the marginnal and inner parta of about 20 Circular atructures showen in remote-sensing image.The various rocks of the greenatone belt in the western and central parta of Kang-dian earth's axis are commonly high in gold Content as the souree of gold in mineralizations.On the basis of distribution of gold deposits and occutrences four Mineralization areas are recognized in this region.
