| 摘 要： | 湖北张福山铁矿属矿浆-热液过渡型矽卡岩矿床。蚀变矿化具有立体分带性(分五个带)。从矿浆贯入到热浪交代带是连续过渡的,成矿温度由高到低,矿石TFe/FeO的比值逐渐升高,CaO的含量由低变高,品位由高变低,蚀变强度逐渐增强,矿体与围岩由截然接触渐变为过渡关系。最后本文对矿床的成矿机制进行了探讨。

| Abstract: | A skarn iron ore deposit of ore magmatic-hydrothermal
transitional type, Zhangfushan deposit in Hubei manifests a spacial zonal distribution in altered mineralization.Five zones are recognized and they are successively transitional from ore magmatic intrusion to hydrothermal metasomatism. Mineralization temperature varies from high to low. TFe/FeO value increases gradually,so does CaO content.The grade decreases and alteration intensifies increasingly. The contact between ore body and country rock changes from apparent to transitional. Finally, mineralization mechanism is discussed. |
