波罗的海沿岸含磷区就其远景储量和适于开发的分布区域而言,可认为是目前最大型的磷块岩基地之一。该区的磷块岩储量约占全苏采块岩储量的15～20％。它在供给磷肥生产所需原料方面的作用最近可望增大。该区的马杜和金吉谢普两矿床正在进行露天开采。托尔谢、阿泽里矿床已探明,拉克维尔含磷区正处于普查勘探阶段,其中卡 The phosphorus-bearing zone on the Baltic Sea is considered to be one of the largest phosphate rock baselines for its long-term reserves and suitable distribution areas for development. Phosphorite reserves in this area account for about 15 ~ 20% of the reserves of the whole Jiangsu block. Its role in supplying raw materials for phosphate fertilizer production is expected to increase recently. The Madhu and Jinjiseipu deposits in the area are undergoing open-pit mining. Thorce, Azeri deposit has been proven, Rickville phosphorus area is in the census stage, in which the card
