摘要
大井头地区隐爆角砾岩主要分布在大井头、归后庄和埠西桥等地,隐爆角砾岩与中生代形成的铜石杂岩体具有成因关系。结合化学分析、微量元素、激电中梯测量资料,分析了该区隐爆角砾岩的金成矿性,确定了归后庄、埠西桥为不成矿隐爆角砾岩,查明大井头隐爆角砾岩具有较好的成矿前景,并通过激电中梯测量圈定了一个极具成矿前景的靶区。
Crypto-explosive breccia occurs at Dajingtou, Guihouzhuang, Puxiqiao etc. , and is genetically related to Mesozoic Tongshi complex. Combined with chemical analysis, micro-element study and IP mid gradient array data the paper analyses probability of formation of gold ore in the crypto-explosive breccia and Guihouzhuang, Puxiqiao are determined as non-ore-bearing crypto-explosive breccia and Dajingtou as the prospective crypto-explosive breccia. Then a prospective target is located through IP mid gradient array survey.
