湘南铜山岭矽卡岩铜铅锌矿床产于铜山岭岩体北东缘隐伏接触带及其外围地层中,在成因上与铜山岭花岗闪长斑岩密切相关。铜山岭铜铅锌矿床具有独特的成矿分带,从岩体向外依次发育近端内矽卡岩、近端外矽卡岩、硫化物-石英脉和远端矽卡岩矿体。根据穿切关系、交代结构和矿物组合等地质特征可以把铜山岭铜铅锌矿床划分为4个矿化蚀变阶段,从早到晚依次为进变质矽卡岩、退变质矽卡岩、石英-硫化物和碳酸盐阶段,其中石英-硫化物阶段为主成矿阶段。闪锌矿成分压力计研究表明,近端内矽卡岩型团块状硫化物矿石中闪锌矿的形成压力为(3.1±1.0)×10~8 Pa,对应的成矿深度为6~12 km,相当于中-上地壳水平,说明铜山岭铜铅锌矿床形成于较大深度。近端内矽卡岩、近端外矽卡岩和远端矽卡岩中都存在两阶段绿泥石。绿泥石成分温度计研究表明,3类矽卡岩中退变质矽卡岩阶段绿泥石的形成温度分别为345~388℃、296~376℃和296~338℃,代表各类矽卡岩形成温度的下限;石英-硫化物阶段绿泥石的形成温度分别为270~318℃、209~238℃和200~223℃,代表各类矽卡岩矿体的成矿温度。3类矽卡岩的绿泥石温度表现出逐步降低的趋势,指示近端内矽卡岩、近端外矽卡岩和远端矽卡岩矿体依次形成。 |

The Tongshanling Cu-Pb-Zn skarn deposit in southern Hunan occurs in the northeastern concealed contact zone of the Tongshanling pluton and its peripheral carbonate strata. It is genetically intimately associated with the Tongshanling granodiorite porphyry. The Tongshanling Cu-Pb-Zn deposit exhibits a distinctive outward zonation of proximal endoskarn, proximal exoskarn, sulfide-quartz vein, and distal skarn orebodies from the contact zone. According to cross-cutting relationships, replacement textures, and mineral assemblages, the Tongshanling Cu-Pb- Zn deposit can be divided into four stages of alteration and mineralization, i.e., prograde skarn, retrograde skarn, quartz-sulfide, and carbonate stages in sequence, in which the quartz-sulfide stage is the main ore stage. Sphalerite compositional barometry manifests that, the sphalerite in the massive sulfide ore of proximal endoskarn formed under (3.1±1.0)×10~8 Pa, corresponding to a middle to upper crustal depth of 6~12 km, indicating that the Tongshanling Cu-Pb-Zn deposit was formed at a deep environment. There are two stages of chlorites in the proximal endoskarn, proximal exoskarn, and distal skarn. Chlorite compositional thermometry manifests that, for the three types of skarns, the chlorite of retrograde skarn stage formed at 345~388℃, 296~376℃, and 296~338℃, respectively, representing the lowest temperatures of skarn formation; and the chlorite of quartz-sulfide stage formed at 270~318℃, 209~238℃, and 200~223℃, respectively, representing the temperatures of mineralization. The three types of skarns display a declining trend of chlorite temperature, indicating that the proximal endoskarn, proximal exoskarn, and distal skarn orebodies were formed in sequence. |
