四川道孚县佐莫那协铁矿床地质特征及控矿因素
|
摘要
佐莫纳协铁矿产于炉霍-道孚构造带葛卡花岗闪长岩与结晶灰岩接触带。矿区出露3条矽卡岩带和3个铁矿体,矿体均赋存于花岗闪长岩体与结晶灰岩接触交代形成的矽卡岩带中,矿体形态、产状的变化与矽卡岩体具有一致性。研究认为碳酸盐岩地层、花岗闪长岩的侵入、北西向鲜水河断层的多次活动及其后期走滑剪切作用形成的北东向断层是区内矽卡岩型铁矿形成的重要控制因素。根据成矿条件分析及磁异常显示,矿区深部及外围尚有矽卡型铁矿找矿潜力。
The Zuomonaxie iron deposit lies at the contact between granodiorite and crystalline limestone in the Luhuo-Daofu structure belt. Three skarn bands,corresponding to three iron mineralization bodies,are exposed in the mining district. The ore bodies are all found in the contact of garnet,diopside skarns between granodiorite and crystalline limestone. The variation of the form and occurrence of ore bodies are in accordance with the hosting skarns. This study suggests that the nature of carbonate strata,the intrusion of granodiorite,the multiple activities of the NW trending Xianshuihe fault,and the NE fault caused by the effect of late-stage strike-slip shear-structure,are the factors that control jointly the formation of Skarn-type iron deposit. Analysis of ore-forming conditions and the magnetic anomalies indicates that there are still potential in finding skarn-type iron deposits in deep subsurface and periphery of this mine area.
