| 摘 要： | 报道了在个旧锡矿松树脚矿区发现的脉状锡石一赤铁矿一方解石新型矿体，认为该新型矿体很可能是成矿流体运移的通道，同时对其成因进行了初步探讨。通过与红海型热水沉积矿床的特征进行对比分析，提出个旧锡矿“层间氧化矿”以及红海型热水沉积矿床中铁氧化物型矿床可能存在2种成因模式：第一种是热卤水自海水向海底沉积物、从上到下的热卤水分层氧化模式；第二种是成矿流体自地下深部向海底的从下到上逐步氧化模式。 |

| Abstract: | Cassiterite-hematite-calcite vein-type orebody was found in Songshujiao mining area of Gejiu Tin-deposit,and was reported in this paper.Preliminary study shows that the vein-type orebody is the result of the late ore-forming fluid condensated in the transport channel.The paper also preliminary discussed the cause of its genesis.According to the comparison between the Gejiu tin-polymetallic deposits and the Red Sea-type hydrothermal deposits,we believe that there are two models for the Interstratified oxidiz... |
