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。
During the Hercynian-Indosinian period from the Phosphorus (Iron) deposit in the deposit, the deep faults simultaneously active in all directions, providing a continuous source of provenance for rock mass and ore deposits. Space. The rock mass differentiates and evolves in the thick caprock beneath the caprock, accompanied by the wide and gentle folds of the Indosinian. It fully reflects the geological environment of the tectonic setting formed at the initial stage of activation of the quasi-platform.
