| 摘 要： | 西南地区广泛发育的面型风化磷矿为一种新的磷块岩矿石工业类型，它是由碳酸盐类磷块岩经风化作用，达到适宜的风化程度而形成的，矿石含镁低，是生产高浓度磷肥的优质矿产资源。磷块岩中碳酸盐矿物的淋失是风化磷矿形成的根本原因，可采用碳酸盐矿物含量多少来确定磷矿石的风化程度，一般在新的勘探矿区使用 CO_2判别标志(风化指标)来判别，在老的勘探矿区采用2P_2 O_5+HP 判别标志判别。今后在对磷矿区进行勘查评价时，应对风化磷矿进行评价，首先确定该区的风化指标，将风化磷矿作为一种类型单独固定；对已勘查的磷矿区，可对磷矿进行二次评价，利用风化指标将风化磷矿单独固定。

| Abstract: | The plane weathered phosphoric ore developed widely in southwest of China as a new commercial typeof phosphorite ore.It was formed by the carbonate phosphorite weathering and reaching an appropriateweathered degree.It is a high-grade mineral resource to produce high quality phosphate fertilizer with lowcontent of magnesium.That the carbonate mineral in phosphorite is dissolved and run off is the basic reasonof the formation of weathered phosphoric ore the content of carbonate mineral can be used to judge theweathered degree of phosphorite.In general,the judging mark of CO_2(weathered index)can be used in thenew prospecting mine area and the judging mark of 2P_2O_5+HP(weathered index)can be used in the oldprospecting mine area.When we explore and assess a phosphorus mine area,we should assess the weatheredphosphoric ore at the stone time and identify its weathered index and then mark off it as a separate type.Toexplored phosphorus mine area,we can reassess it and mark off the weathered phosphoric ore separately byweathered index. |
