在总结清白山铅锌矿矿床地质特征、控矿因素的基础上,通过与MVT型矿床典型特征对比,认为其成因类型为MVT型。通过总结控矿因素,讨论了成矿时代,初步建立成矿模型,认为矿床成型分为含矿流体沉淀的主成矿期、构造改造期、岩浆改造期3个阶段。 相似文献

山东蒙阴西峪金刚石原生矿床位于华北克拉通东缘。结合区域地质背景、矿床和矿（化）体地质特征,对该矿床的成矿地质条件、控矿因素和矿床成因进行研究。结果表明,断裂是该矿床主要的控矿因素,矿床的形成及分布与区域NNE向沂沭断裂带、上五井断裂和NWW向新泰—垛庄断裂、铜治店—蔡庄断裂有关,金刚石矿大多产于这些断裂的交接复合部位,是金伯利岩浆的运移通道和储存空间;金刚石是加里东期金伯利岩浆作用的产物。 相似文献

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.
