最近苏北地区发现不少次生淋滤洞穴堆积型磷矿床,是可喜的消息。过去总被人认为这种类型的磷矿主要产于广西、云、贵诸省,如今在苏北来个突破,这就开阔了找磷的境界。同时也有力地说明,在碳酸盐岩类广泛分布的地区,尤其是厚层状或中厚层状、质地较纯的石灰岩产出的地方,例如华北、东北、西北,都可广泛发动群众普查找矿,逐步改变我国磷矿资源分布不均、南磷北运的局面,为支援农业生产作出贡献。 Recently, many secondary leaching caverns accumulation type phosphate deposits have been found in northern Jiangsu Province, which is a welcome news. In the past, people always thought that this type of phosphate rock was mainly produced in Guangxi, Yunnan and Guizhou provinces and now makes a breakthrough in northern Jiangsu. This opens up the realm of finding phosphorus. At the same time, it is also strongly argued that masses can be mobilized widely in places where carbonate rocks are widely distributed, especially thick-bedded or medium-thick layered and purer limestone, such as North China, Northeast China and Northwest China Census prospecting, and gradually change the uneven distribution of phosphate rock resources in China, North Pandan situation, to contribute to supporting agricultural production.
