| 中文摘要: |
| 通过小娘坑锰铅锌矿床地质及地球化学特征的研究,结合区域资料,论述了发育于区内T1Xa层中的含矿角岩层系①及锰铅锌矿,是一套典型的海底(火山)喷流-热水沉积岩(矿),并探讨其成因机制。这种热水沉积岩-角岩层系是区域上一种重要的找矿标志。 |
| 英文摘要: |
| Introduction to ore-bearing horizon sedimentary phase, palaeo-gtographical environment, structures of ore deposit, ore features (including S, Pb, H, O and C isotopic composition), abundance of ore-forming eleinents, micro-elements and their ratio and geochemical characteristics is based on the data obtained mainly during the project assumed by the author. Together with regional geological survey data draws a conclusion that iron deposits, Mn-Pb-Zn deposits in hornfel sequency (T1Xa) are not the pratuct of contact metasomatism nor the alteration product by late hydrothermal overprint, nor normal marine sedimentation; they are products of submarine (vdcahic) erupted flow-hot water sedimentation. The hoinfel is metallogenic mark in the area. |
