摘要
2005年在西藏达孜县羌堆铜矿区进行了1/2.5万的路线土壤测量(40 km2),路线土壤测量省力经济,适用于地形复杂、植被发育的通行困难地区;根据土壤测量的地化异常特征推断了3条断裂、3个半隐伏-隐伏的斑岩体,发现12处地化异常,其中11-A为已知矿致异常,8-A,4-B,6-A,9-A异常分别为寻找斑岩型铜矿、构造蚀变岩型金矿的良好靶区,可安排地质物探综合普查。
In 2005 40 km^2 traverse soil survey along lines at scale of 1/25 000 was done in Qiangdui area, Dazi county, Tibet. Such survey saves labor and is economic and applicable in complicated topographic area where is covered with heavy vegetation and traffic is very difficult. On basis of the survey we inferred three faults, three semi-buried-wholly buried porphyry rock bodies and locate 12 geochemical anomalies of which ll-A is caused by the known ore deposit, and 8-A, 4-B, 6-A and 9-A are the targets for porphyry copper deposit and altered cataclatistic rock type gold deposit.
