一、矿区地质概况矿区出露地层为下二迭统,其上被第三系及第四系所覆盖。下二迭统又分为两个岩组,在勘探区仅出露有P_1～a,依其岩性又可划分为九个岩性段,即P_1～(a2-10),由一套细碎屑岩及灰岩透镜体组成。其中P_1～(a7)为主要矿体的赋存层位,由变质细砂岩、粉砂岩、角岩、角岩化条带状千枚岩、大理岩透镜体及斑点板岩、条带状大理岩化灰岩组成,地层倾向235°-255°,倾角45°。
First, the mining geological profile Mining outcrop formation for the next two Diego, which was covered by the Tertiary and Quaternary. The Lower Second Permian is further divided into two groups of rocks. Only P_1 ~ a is revealed in the exploration area, and can be divided into nine lithologic sections according to their lithology, that is, P_1 ~ (a2-10) Clastic rocks and limestone lens body composition. Among them, P 1 ~ (a 7) is the host layer of the main orebody, and is composed of metamorphic fine sandstone, siltstone, hornfels, angular rock banding phyllite, marble lens and speckled slate, Rock limestone composition, strata tendency 235 ° -255 °, dip 45 °.
