| 摘 要： | 产于层状镁铁-超镁铁杂岩内的攀枝花（式）钒钛磁铁矿矿床,是岩浆重力分异与结晶分异——火成堆积过程中铁-钛矿浆逐步聚集形成的。成矿作用与成岩作用协调进行,并贯穿于成岩的全过程。作者认为该类矿床不宜归入晚期岩浆矿床,拟称岩浆分异-分凝矿床。该类矿床生成于岩浆房不断扩容和释压的构造环境,因而是大陆裂谷带特征性岩浆矿床。

| Abstract: | Panzhihua-type vanadio-titanomagnetite ore deposit occurrs in layered mafic and ultramafic complexes, which is the product of gradually accumulation during Fe-Ti ore-bearing magma gravitative and crystallization differentiation-and igneous cumulation process. The mineralization was congruent with the rock-forming process, and consistent throughout the whole process. The author regard this kind of ore deposit as magmatic differentiation and segregation ore deposit, not late magmatic ore deposit. Because the ore deposif are formed under the continuous chamber dilation and pressure releases so that the ore deposit is a typical plutonic ore deposit in the continental rift setting. |
