| 摘 要： | 湖北钟祥莲花山矿段为大型磷矿床,其第一磷矿层(Ph1)的矿体分布不均匀。通过研究矿层顶底板的岩石,探讨了矿体分布的规律性。研究认为,底板岩石(页岩和含锰白云岩)的厚度与Ph1厚度相关性很高,并严格制约着Ph1的分布,表明在莲花山矿段因沉积时地势的起伏导致古海水深度不同,水体较深的区域一般沉积有含矿层位,水体较浅的区域含矿层变薄甚至缺失。这一规律可指导成矿预测及矿床深边部的找矿工作。

| Abstract: | Lianhuashan phosphate deposit is a large phosphorous deposit. Phosphorous ore bodies of the first phosphate layer (Ph1) are not uniformly distributed. We study the hanging and foot wall rocks to explore the distribution regularity of the ore bodies. Result of the study shows that thickness of the foot wall rock (shale and manganiferous dolomite) is highly correlated with that of Ph1 and strictly control its distribution and suggests that relief at its deposition lead to different depth of the palaeo-sea. Ph1 is thickly deposited at places where the sea water is deep and thinly or not deposited where is shallow. This viewpoint will guide the ore prospecting at margin and depth of the deposit. |
