    摘要:

    西徐格庄石墨矿地处鲁东中部地区,属“区域变质型”晶质石墨矿床。可划分5条含矿带,共圈定石墨矿层20个,其中主矿层2个,倾向SE,倾角46°~82°,矿床平均品位2.93%,矿石类型主要为含黑云变粒岩型。本文通过对区内成矿地质背景、矿床地质特征、矿体特征、矿石特征等进行了分析,探讨了石墨矿成因,总结了找矿标志,对区内石墨矿找矿前景进行了分析,为今后该地区的石墨矿勘查提供借鉴。

    Abstract:

    Xixugezhuang graphite deposit is located in the middle of eastern Shandong province. It belongs to regional metamorphic crystalline graphite deposit. It can be divided into five ore bearing zones, and 20 ore beds of granites have been circled, including 2 main ore beds with the trend of SE. The inclination is 46 °~82 °, and the average grade of the deposit is 2.93%. The ore types are mainly biotite bearing granulite type. Based on the analysis of metallogenic geological background, deposit geological characteristics, ore body characteristics and ore characteristics in the area, the origin of graphite deposit has been discussed, prospecting signs have been summarized, and prospecting prospect of graphite ore has been analyzed. It will provide some references for graphite ore exploration in this area in the future.
