塔东磷铁矿床位于吉林省敦化县与黑龙江省宁安县交界处。该矿床以铁为主,并伴有磷、钒、镓、硫、钴、稀土等多种有用元素,具有规模大、品位低、有害组分少、易选、多种元素伴生等特点,属于热液富集式火山沉积变质矿床,其成因类型和工业类型较为特殊而复杂。因此,研究该矿床的地质特征和成因机理对找矿勘探、有益元素的综合利用具有十分重要意义。
Tadong Phosphorite deposit is located at the junction of Dunhua County, Jilin Province and Ning’an County, Heilongjiang Province. The deposit is mainly iron and is accompanied by many useful elements such as phosphorus, vanadium, gallium, sulfur, cobalt, rare earth and the like, and has the characteristics of large scale, low grade, few harmful components, easy selection, Hydrothermal enriched volcanic sedimentary metamorphic deposits, the genetic type and type of industry is more special and complex. Therefore, it is of great significance to study the geological characteristics and genetic mechanism of this deposit for prospecting and comprehensive utilization of beneficial elements.
