东秦岭及邻区各矿带稳定同位素地球化学研究

区域成矿带Pb、S、H、O等稳定同位素地球化学研究是阐明矿带内成岩、成矿物质来源、矿床成因的有效途径。我们在东秦岭及邻区成矿规律的地球化学研究中把同位素示踪作用与各构造环境中源区和物理化学条件结合起来,把矿带内Pb、S、H、O等几种同位素示踪作用互相联系起来,较好地揭示了东秦岭及邻区区域地壳(岩石圈)演化过程中成岩、成矿机制。

Stable isotope geochemical studies of various metallogenic belts in east Qinling and neighboring areas

Geochemical studies of stable isotopes such as lead, sulfur, hydrogen and oxygen in regional metallogenic beIts seem to be an effective way to approach sources of rock-forming and ore-forming substances and geneses of ore deposits. During the geochemical study of metallogenic regularity for east Qinling and neighboring areas, the author combined the isotope tracer function with provenances and physicochemical conditions of various tectonic environments and connected several isotope tracer functions such as lead, sulfur, hydrogen and oxygen together. In this way, much light has been thrown on the rock-forming and ore-forming mechanism in the process of the evolution of the regional crust (lithosphere) in east Qinling and neighboring areas.
