中文摘要:
      本文根据矿物、岩石、微量元素、稀土元素及同位素的研究,重点讨论了我国近年新发现的北方地区第一条独立锡矿带的海西期含锡和非含锡花岗岩的地质特征,确定了该区花岗岩的成因类型及其与锡矿化的关系,认定该区伴随海西运动出现I型、S型和A型三种花岗岩。与锡矿化有关的属S型和A型花岗岩,它们是在早期(造山期)I型和S型花岗岩的基础上进一步演化而隶属造山晚期—造山期后的产物。在上述研究的基础上,总结了该区含矿花岗岩与无矿花岗岩的综合判别标志,为该区及邻区同类锡矿的找寻与研究提供了依据。
英文摘要:
      Located in East Junggar area, Xinjiang, the Beiledukuk ore belt is an independent tin metallogenic belt discovered for the first time in northern China in recent years. It has four independent tin deposits, several tinoccurrences and one tungsten occurrence. The primary tin deposits consistof quartz vein tin deposits related to S-type granites and tin depositsassociated with Artype (alkaline) granites. The belt strikes northwest alongthe northern side of the Kalamaili suture zone between Junggar and Yemaquan.The paper mainly discusses geological characteristics of the Hercynian stanni-ferous and tin-absent granites in the tin metallogenic belt. It is believed thatI-, S-and A-type granites of this area were formed during the Hercynian move-ment. The highly differentiated and evolved S-and A-type granites -elated totin mineralization are poducts of the late orogenic-postorogenic stage, formed on the basis of further evolution of early-stage (orogenic) I-and S-type gra-nites. The integrated criteria for discriminating between ore-bearing and barrengranites have been summarized, which are conductive to the search and study of tin deposits of the same types in this area and its neighboring areas.
