山东省大汶口盆地侵入岩分布及岩性特征

Distribution and Lithologic Characters of Intrusive Rock in Dawenkou Basin of Shandong Province

大汶口盆地内蕴含丰富的矿床资源,发现有岩盐、石膏、自然硫等矿产。在地质勘探施工的钻孔中,发现辉绿岩侵入体,赋存深度130.35 m^529.54 m,单孔累计厚度在0.19 m^63.33 m之间,是沿沉积地层顺层侵入。以往地质勘探工作未对侵入岩的特征进行分析和研究,在总结以往的地质勘查中发现的侵入岩,就其地质特征、赋存情况和对矿层的破坏程度等进行了讨论,为今后的地质勘查提供参考依据。

There are rich mineral deposits within the Dawenkou Basin, and halite, gypsum, natural sulfur and other minerals hasbeen found. In the drilling in construction of the geological exploration, diabase intrusions with occurrence depth of 130.35 m-529.54 m and hole cumulative thickness between 0.19 m-63.33 m has been found, which intrudes along sedimentary stratum. Thegeological exploration work in the past did not analyze and study the characteristics of intrusive rock. Summarizes the intrusiverock found in previous geological exploration, and discusses its geological features, occurrence and the extent of damage to the orebed to provide reference for geological prospecting in future.
