| 摘 要： | 个旧东区印支期玄武岩对个旧锡多金属矿床的形成有重要的作用.作者应用玄武岩系柱状对比图和内插法作等值线的方法,分析了个旧东区印支期玄武岩的时间和空间分布情况.结果表明,个旧东区安尼锡克期的火山活动的时间和空间的大体演化趋势是,随着时间的推移火山活动的空间由南往北演变.同时,在仙山坡一带-母鸡山一带-期北山一带可能是火山喷发中心.这对个旧锡矿深部和外围的进一步找矿勘探具有一定的指导意义.

| Abstract: | The basalt of the Indo-Chinese epoch in the eastern Gejiu plays an important role in the formation of the Gejiu tin-polymetallic ore deposits. This paper analyzes the distribution of the basalts of the Indo-Chinese epoch in time and space in the eastern Gejiu by means of comprehensive basalts corrlation column and isometric line. The result proves that the evolutional tendency of time and space of the basalts of the Indo-Chinese epoch in the eastern Gejiu is that along with the evolution of time, the space of the volcanism changed from south to north. The Xianshanpo-Mujishan-Qibeishan area possibly is the center of the volcanism and will play a definite role in exploring the deep part and periphery of the Geiiu tin ore deposit. |
