涅帕(Hena)含钾盆地位于西伯利亚地台南部,伊尔库茨克地区北部的涅帕河和下通古斯卡河流域。盆地内钾盐矿化面积达二万二千多平方公里,钾盐矿床面积约一万平方公里。含钾层产于下寒武统安加拉组下部,分数层产出,厚度可达几十米。钾盐矿体一般埋藏较浅。钾盐矿石矿物成分简单,主要为钾石盐,次为光卤石;氯化钾含量达25—55%,几乎不含不溶杂质。预测钾石盐矿石储量可能达七百亿吨,现在正继续勘
The Hena potassium-bearing basin is located in the southern Siberia platform, in the Nepalese and Lower Tunguska rivers in the northern part of the Irkutsk region. Potash mineralization in the basin area of over 22,000 square kilometers, potash deposits area of about 10,000 square kilometers. K-bearing layer is produced in the lower part of the Lower Cambrian Angara Formation, with several layers of thickness and thickness up to tens of meters. Potash ore body generally buried shallow. Potash mineral composition is simple, mainly potassium salt, followed by carnallite; potassium chloride content of 25-55%, almost no insoluble impurities. It is estimated that the potash salt ore reserves may reach 70 billion tons, and the exploration is continuing
