摘　　要：四川雷波地区寒武系下统麦地坪组岩层普遍有磷矿层产出,勘查成果显示,该磷矿层稳定,品位高,规模大,为古陆边缘浅深海-半封闭滞流海湾相生物化学沉积型磷矿床。通过雷波马颈子—牛牛寨地区磷矿床成矿地质背景介绍,指出了该区磷矿具有良好的找矿远景。The Lower Cambrian Maidiping Formation in Leibo, Sichuan is phosphorite-hosted. The exploration results indicate that the phosphorite is charcterized by stable horizon, high grade and large scale, being a biochemical-sedimentary deposit in a semi-enclosed stagnant bay. Geological setting in the Majingzi- Niuniuzhai region shows good prospecting perspective for the phosphorite deposit.
