礦田位于務(wù)川汞礦帶的中部，受北北東向木油廠背斜構(gòu)造的控制。礦田由南北兩段的礦床所組成：北段包括蓬巖、嶺旗山、白洋面和水幅4個(gè)礦床；南段包括三家田、小岬口及茅坪頭3個(gè)礦床。
礦田范圍內(nèi)出露地層為寒武系(圖3.15.3)，汞礦化見于寒武系中、下統(tǒng)，礦化厚度達(dá)800多m，但較穩(wěn)定的礦化和工業(yè)礦體只見于由C—1q2-2到C—2g3厚300余m的碳酸鹽巖巖中。礦體沿背斜軸分布、富集。主礦層產(chǎn)于C—1q3-2頂部，礦層連續(xù)而穩(wěn)定，礦層沿軸長達(dá)4000多m，寬幾百m，嚴(yán)格地受背斜軸部控制。在平面上隨軸向彎曲而彎曲(圖3.15.3)。圍巖蝕變以方解石化為特點(diǎn)、硅化次之。礦石組成較簡(jiǎn)單，礦石礦物主要是辰砂，有少量輝銻礦、閃鋅礦，偶見雄黃、方鉛礦、輝銅礦等。礦石工業(yè)類型以碳酸巖單汞辰砂礦石為主。礦石平均品位含汞0.147%。礦床類型屬碳酸鹽巖型層控層狀汞礦床。
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.
