本文对红旗岭锡多金属矿床的地质特征、矿物化学及硫、氧同位素组成等多方面进行了讨论,并指出该矿床为岩浆期后中高温热液充填型矿床,成矿温度为250—520℃。通过对该矿区深部隐伏岩体的岩石化学、稀土组成、微量元素以及绝对年龄等方面的研究和对比,表明红旗岭隐伏岩体相当于千里山第二次侵入岩并具有潜在的成矿意义。
This paper discusses the geological characteristics, mineral chemistry, sulfur and oxygen isotopic compositions of the Hongqiling tin polymetallic deposit, and points out that the deposit is a mid-high temperature hydrothermal-typed mineral deposit after the magmatic period with a metallogenic temperature of 250-520 ℃. The study and comparison of the petrochemical, rare earth composition, trace elements and absolute ages of the concealed horizons in the deep mining area show that the Hongqiling horizons is equivalent to the second intrusive rock in the Qianshan Mountains and has the potential significance of mineralization.
