【摘要】 通过详细的岩石学特征、接触关系、地质时代以及含矿性等研究,特克斯达坂岩基可解体为早石炭世库勒萨依序列和早二叠世其那尔萨依序列,其同位素年龄分别为347Ma和291~292Ma,地质调查已证实,两序列间为侵入接触关系。并于解体出的库勒萨依两序中新发现了斑岩型钼矿体。特克斯达坂岩基的解体,客观反映了岩浆活动的特征,不仅为深化区域成矿规律和指导进一步找矿具有重要意义,而且为丰富构造岩石组合资料和探讨本区大地构造演化有重要理论价值。更多还原

【Abstract】 Detailed field investigations on petrology, contact relationship, emplacement ages and ore-forming potential of granitic intrusion show that the Tekesi Daban batholith could be disintergrated into two intrusive series: one is Kulesayi series (ca. 347Ma, early Carboniferous) and the other is Qinaersayi series (291~292Ma, early Permian), respectively. Field investigation and exploration indicate that there exist intrusive contact relationship between the Kulesayi and Qinaersayi series, and a new porphyry molybdenum deposit was discovered in the Kulesayi series. The disintergration of the Tekesi Daban batholith provides important constraints on the magmatic evolution of the Paleozoic granitic magmas and the related ore formation.更多还原
