Unique Geologic Association of Boron Skarn and Pb-Zn Skarn Mineralization in the Dal'negorsk Region, CIS

9526876 Meinert Dal‘Negorsk夕卡岩项目提供了一个机会，将美国在夕卡岩矿床领域的学术专业知识应用于研究表面上独特的地质环境，包括硼和铅锌夕卡岩矿床。本研究将探讨达勒涅戈尔斯克矿床的成因，并论证硼硅酸盐与区内铅锌矽卡岩型成矿的关系。地质填图、岩石学、矿物学和流体包裹体研究将检验数据岩和铅锌矿化与同一侵入热液事件在成因上有关的假设。1994年的实地考察收集了一组重要的矽卡岩样，但仍有两项任务只能通过第二次实地考察才能完成。第一种是最少两到三周的矿床和矿床间比例尺地质填图。第二项任务是更详细地研究火成岩和这两种夕卡岩类型之间的关系。资金用于支付前往独联体外地地点的交通费用。

9526876 Meinert The Dal'negorsk skarn project presents an opportunity to apply American Academic expertise in the are of skarn deposits towards the study of an apparently unique geological setting containing both boron and lead-zinc skarn deposits. This research will investigate the genesis of the Dal'negorsk deposit and demonstrate the relationship between borosilicate and lead-zinc skarn mineralization in the district. Geological mapping, petrologic, mineralogic and fluid inclusion studies will test the working hypothesis that datolite and lead-zinc mineralization are genetically related to the same intrusive-hydrothermal events. A 1994 filed visit allowed for the collection of a significant skarn sample suite, but two tasks remain that can only be accomplished by a second field visit. The first is a minimum of two to three weeks of deposit and inter-deposit scale geological mapping. The second task is to examine in greater detail the relationship between igneous rocks and the two skarn types. Funding to cover transportation to the field site in the CIS.
