| 摘 要： | 扬子地块是我国重要的产磷区 ,陡山沱与梅树村两大成磷期磷块岩储量占全国磷矿储量的85 %。在多年来丰富的资料积累与研究基础上 ,经过实践—理论—再实践的认识过程 ,归纳与提练出具有共性和普遍适用的海相磷块岩区域成矿规律 ,上升成为理性认识 ,因而具有很强的实用性 ,可作为成矿预测的准则。这些规律有 :含磷岩系规律、磷矿层规律、磷块岩自然类型规律、磷块岩结构类型规律、磷块岩矿物与化学成分规律、磷块岩序列规律、磷块岩成矿的构造古地理规律、陆缘坻含磷岩组规律、磷块岩富集规律等。并在此基础上划分出扬子地块的 2个三级成矿亚带和若干四级成矿区。

| Abstract: | Yangtze massif is known for the leading phosphogenetic area in China, especially in the times of Doushantuo and Meishucun ages when the sedimentary phosphorite account for 85% of the state's total phosphorus resources. Many years of gathering and analyzing large amounts of the existing data about sedimentary phosphate rocks has allowed to conclude a variety of the regional ore-forming regulations, general and practical, concerning marine phosphorite. These regulations are of phosphorus-carrying rock series, phosphate strata, natural types of phosphorite, mineral and chemical composition of phosphorite, succession of phosphorite, tectonic paleogeography of phosphorite, association of different phosphate rocks on "luyuanchi", and enrichment of phosphorite. Worked out through a process from practice to theory back to practice, they are so practicable as to be used for guides for hunting marine phosphorite. |
