它温查汉西C5 异常区经过连续勘查已完成了详查,共计施工钻孔 165 个,见矿钻孔 102 个,圈定矿体 47条,编号Ⅰ-1~Ⅰ-47 矿体.本文通过对矿区主矿体特征进行总结,以地质勘查新规范为基础,对本区矿床勘查类型进行论述,为该区工程部署及资源量估算提供依据,同时为矽卡岩型铁多金属矿床勘查类型的确定提供参考.根据各主矿体的特征,求得矿区铁矿的五个地质因素类型系数值之和为1.52,铜矿为1.64,锌为1.57,确定矿区主矿产铁的勘查类型为Ⅲ类型、铜矿产的勘查类型为Ⅱ~Ⅲ类过渡,铅、金、锌矿产的勘查类型为Ⅲ类型.综上,矿区铁矿的基本勘查工程间距为100 m×50 m,铜矿的基本勘查工程间距为100 m×80 m;铅锌勘查基本网度为50m×50 m.通过对矿区勘查类型的论述,重新优化了工程布置,并估算(控制+推断)铁矿石量2 007.90×104 t;控制+推断铜金属量7.61×104 t;控制+推断锌金属量6.05×104 t;控制+推断金金属量2 861.17 kg,资源量达到了中型矿床规模.
Geological Characteristics and Exploration Types of C5 Anomaly Area in the West of Tawenchahan Area of East Kunlun
A detailed survey has been completed after continuous exploration in C5 magnetic anomaly area of the west of Tawenchahan area.A total of 165 boreholes have been drilled,102 ore deposits have been found,47 ore bodies have been delineated,numbered Ⅰ-1 to Ⅰ-47 ore bodies.According to the characteristics of each main ore body,the sum of the five geological factor type coefficients for iron ore is 1.52,copper is 1.64 and zinc is 1.57.It is determined that the exploration type of iron ore is Ⅲ,that of copper ore is Ⅱ-Ⅲ transition,and that of zinc,lead and gold ore is Ⅲ.In summary,the basic exploration engineering spacing of iron ore is 100 m×50 m,and that of copper is 100 m×80 m;The basic net degree of lead and zinc exploration is 50 m×50 m.Based on the dis-cussion of the exploration type of the mining area,the engineering layout is reoptimized,and the iron ore quantity is estimated(controlled + inferred)to be 2 007.90×104 t.The controlled and inferred copper ore content is 7.61×104 t.Control + inferred zinc ore content is6.05×104 t;Control + inferred Au ore content is2 861.17 kg.The a-mount of resources has reached the medium-sized deposit scale.
