摘要:

根据对大别山南部宿松磷矿含磷地层的区域分布、地层序列、时代归属、构造变形的系统研究,提出磷矿层属震旦系的新认识。含磷岩系经受了两次强烈的变形改造,原始层理经过了强烈改造,宿松磷矿构成总体包络面呈北西西走向、向南倾斜的褶皱化单斜。矿层的多层化、尖灭复合和加厚现象等主要受构造的控制,而非完全受古地形的控制。用褶皱的观点对原先勘探剖面中的磷矿体进行了重新圈连,籍以指导磷矿的调查、评价和开采。最后对磷矿分布的古地理特征进行了讨论,并从构造的观点对磷矿进行了评价。

Abstract:

Based on the systematical study of the regional distribution,strata sequences,chronology and structural deformation of the phosphorus-bearing stratum in the Susong phosphorus deposit,the age of the Susong phosphorus deposit belonged to the Sinian is put forward.The phosphorus-bearing stratum suffered two generations of strong deformations,and the original bedding is strongly reformed.The SuSong phosphorus deposit make up a folded monocline with the tangent plane of the smaller folds orientated NWW,dip to the south.The multilayer,thin out or combination of the phosphorus layers have been formed,which are mainly controlled by structure deformation,not by palaeogeography completely.The phosphorus layers in some former drilling profiles can be reconnected according to the folded theory.It is useful for us to explore and appraise or mine the phosphorite.The distribution of the phosphorus layers in palaeogeography has been described and the phosphorus deposit is evaluated on the structural view.

Key words: Susong phosphorus deposit, Sinian, deformation, structural evaluation, southern part of Dabie Mountains
