中国磷矿资源现状及磷矿国家级实物地质资料筛选

Current status of phosphorite-ore resources in China and screening for national-class physical geological data of phopshorite

磷矿是指在经济上具有利用价值的磷酸盐类矿物的总称,是一种重要的工农业矿物原料,在国内外诸多领域中有着举足轻重的经济价值。磷矿是中国重要的战略矿种之一,在全国范围内均有分布。在分析研究中国磷矿资源特点和成因类型的基础上,将全国磷矿床划分为4个矿床类型,其中最为重要的磷矿床类型包括岩浆岩型磷灰石矿床、沉积型磷块岩矿床及变质岩型磷灰岩矿床。国家实物地质资料馆磷矿实物地质资料筛选应考虑磷矿床成矿规模、矿床类型、成矿省(带)、成矿时代等因素,同时兼顾具有典型、潜力巨大的磷矿床作为筛选对象。

Phosphorite is a general term for all phosphate rocks which are economically valuable.It′s a very important mineral raw material in agricultural and industrial fields.It has a high economy value in many fields at home and abroad.Phosphorite is one of the strategic mineral resources in China and distributes extensively in the whole country.The phosphorous deposits in China have been divided into four types during analysing the formation cause and resource characteristics,the most important types of which are magma phosphate deposit,sedimentary phosphorite deposit,and metamorphic phosphate deposit.Screening of object phosphorous-ore geological data by Cores and Samples Center of Land and Resources should consider scales of gold-ore deposits,genetic types,mineralization provinces（belts）,and metallogenic epochs,as well as the typical gold deposits with enormous potential.
