| 摘 要： | 在矾山磷（铁）矿床生成的海西─印支期，各方向深大断裂同时活动，为岩体和矿床源源不断地提供物源；张宣幔枝构造外围拆离滑脱带为其提供容岩空间；岩体在复盖层下的巨厚沉积盖层中分异、演化，同时伴随着印支期开阔宽缓的褶皱。它充分反映了矿床生成于准地台活化初期的大地构造背景环境。

| Abstract: | Fanshan phosphorus (iron) deposit formed in the Hercynian-Indosinian period when various trending,but synchronously active, deep faults provided its rock bodies and provenance with successive materials.Zhangxun mantle plume structure offered its surrounding decollement zones for hosting the ores, The rockbodies, underlying the massive overburden, began differentiating, evolving and being accompanied by broadfolding during the Indosinian period, all this suggesting that the mineralization featured the initial evolution ofa metaplatform in the background. |
