豫西南含钾岩石特征及其意义

The Characteristics and Significance of Potassium-bearing Rocks in the Southwest He'nan

豫西南地区不溶性含钾岩石资源丰富,主要分为两大类型:沉积岩型和火山岩型,主要有海绿石砂岩、含钾砂岩、伊利石岩、正长岩、花岗岩、钾长伟晶岩,研究利用这些资源对缓解我国的钾资源短缺、振兴河南经济有着重要的现实意义。

The insoluble potassium-bearing rocks resources is rich in the southwest of He'nan. It can be mainly classified into the sedimentary rock and the igneous rock, including glauconitic sandstone, potassium-bearing sandstone, illite, syenite, granite and pegmatite. Exploitation of the resources can reduce the tight supply of potassium-bearing minerals and conduce to promotion of economy of He'nan province.
