碳质与构造应力对铅锌矿床成矿控制作用的探讨

PROBE INTO THE METALLOGENY OF LEAD-ZINC ORE DEPOSITS UNDER THE CONTROL OF CARBON AND TECTONIC STRESS

在现代地质学中,层控多金属矿床的复杂成矿作用,引起广泛争论。为什么贱金属矿床与有机碳具有十分密切的成生联系?在应力作用下,固相岩石中的金属元素如何迁移和富集?本文依照自然辩证法的基本原理,运用类比,模拟和实验等科学方法,抓住有机碳与金属矿床共生这个关键,剖析压溶缝合线与层状矿床的相似性,进行类比逻辑推论。又根据野外的成岩成矿事实,通过模拟实验研究,对上述问题从地质学与哲学两方面进行深入探讨,得出许多有益的成果和启示,为将来解决这些难题提供了一定的线索。

In modern geology, the complex mineralization of stratabound ore deposit has evoked much con-troversy. Why does close genetic connection exsit between base metal deposit and organic carbon? Howdid metal elements in solid rock migrate and concentrate under the action of tectonic stress? Based onthe princeples of dialetic of nature and applying scientific methods of analogy, simulation and experi-ment, the author has grasped the key to paragenesis between organic carbon and metal deposit, analysedsimilarities of press-dissolved stylolite and stratiform ore depost, then made analogy deduction in thispeper. Based on the field petrogenesis and metallogenesis phenomena we have probed into the problemsin both geology and philosophy by simulating experiment, obtained a lot of available achievements andenlightenment, which provide an orientatin to resolve the problems above.
