矿田位于务川汞矿带的中部，受北北东向木油厂背斜构造的控制。矿田由南北两段的矿床所组成：北段包括蓬岩、岭旗山、白洋面和水幅4个矿床；南段包括三家田、小岬口及茅坪头3个矿床。
矿田范围内出露地层为寒武系(图3.15.3)，汞矿化见于寒武系中、下统，矿化厚度达800多m，但较稳定的矿化和工业矿体只见于由C—1q2-2到C—2g3厚300余m的碳酸盐岩岩中。矿体沿背斜轴分布、富集。主矿层产于C—1q3-2顶部，矿层连续而稳定，矿层沿轴长达4000多m，宽几百m，严格地受背斜轴部控制。在平面上随轴向弯曲而弯曲(图3.15.3)。围岩蚀变以方解石化为特点、硅化次之。矿石组成较简单，矿石矿物主要是辰砂，有少量辉锑矿、闪锌矿，偶见雄黄、方铅矿、辉铜矿等。矿石工业类型以碳酸岩单汞辰砂矿石为主。矿石平均品位含汞0.147%。矿床类型属碳酸盐岩型层控层状汞矿床。

Ore field is located in the Wuchuan mercury mine in the central zone, controlled by NNE Muyouchang anticline. The ore field consists of two sections: the northern section of North and South ore rock, including Peng Ling Qishan, white flour and water painting 4 deposit; South includes three fields, a small mouth and head Cape Maoping deposit 3.

The exposed strata in the Cambrian orefield range (Fig. 3.15.3), mercury mineralization in the middle and lower the mineralization thickness more than 800 m, but relatively stable mineralization and ore bodies are found only by C - 1q2-2 to C - 2g3 more than 300 m thick carbonate rocks. Distribution and enrichment of ore bodies along the axis of the. The main ore produced in the C 1q3-2 top, steady and continuous seam, seam along the axis up to more than 4000 m, width of hundreds of M, strictly control the anticlinal axis. In the plane with the axial bending and bending (Figure 3.15.3). The wall rock alteration to calcitization features of silicide. The mineral composition is relatively simple, the main ore minerals is a small amount of cinnabar, stibnite, sphalerite, galena, chalcocite, occasionally realgar etc.. Industrial type of ore to carbonate rock single cinnabar ore mainly mercury. Ore average grade of mercury 0.147%. The type of the deposit belongs to carbonate rock type layer controlled layered mercury deposit.
