摘要:
提要:骑田岭地区锡矿找矿的突破,是近两年国土资源大调查取得的重大成果。区内锡矿产于骑田岭复式花岗岩体南部以及接触带,多呈脉状产出。锡矿类型以云英岩化花岗岩型、蚀变斑状花岗岩型、蚀变构造带型为主,具有矿体厚度大、蚀变强、品位较高、矿石利用性能好的特点。现已估算锡资源量约60万吨,还有成矿条件类似的北部及同一构造岩浆岩带的其他地区,进一步开展该地区国土资源大调查将会扩大现有找矿成果。

Abstract:
Abstract: The breakthrough in tin exploration in the Qitianling area, Hunan Province, is a major achievement scored in the large? Juan scale The Land and Resources Survey in the last two years. Tin deposits in the area occur as veins in the southern part of the Qitianling composite granite body and its contact zone. The dominant tin deposit types include the greisenized granite type, altered porphyritic granite type and altered structural belt type, all of which are characterized by wide and thick orebodies, strong alteration, high tin grade and high performance of ores. At present, tin resources are estimated at about 600000 tons, and, in addition, the northern part of Qitianling with similar metallogenic conditions and other districts in the same tectono? Juan magmatic belt are also promising. More fruitful results will be achieved when the large? Juan scale The Land and Resources Survey is carried out further.
