| 摘 要： | 江汉盆地江陵凹陷深处赋存高温富钾卤水,含卤地层主要是古新统沙市组。富钾卤水的分布受持续的继承性沉降中心(洼陷)、沙市组含盐系、石盐-硫酸盐沉积相的控制,聚集在砂岩、玄武岩、辉绿岩和白云岩等孔隙-裂隙内,裂隙的发育又与局部构造(背斜、盐构造等)枢纽部共轭裂隙带有关。古新世,盐湖已经蒸发浓缩到钙芒硝-石盐阶段,可能短暂达到硫酸镁盐和硫酸钾镁盐阶段。以后,原生的晶间卤水在成岩后期受到玄武岩侵入和高温流体影响,发生变质作用、去镁和去硫酸根作用,同时带入丰富的钾、铷、铯等元素,最后形成了高温富钾卤水。这种成矿过程可称为地下热事件激发成矿机制,值得进一步探讨。

| Abstract: | The potassium-bearing brine with higher temperature had been discovered since 1970s in Jiangling depression of Hubei Province,and the brine mainly being stored in Shashi group of Eocene series.The distribution of brine are controlled by the subsiding center,stratum,halite-sulfates phase.The brine is cumulated in pores and cranies of sand rock,basalt,diabase,dolomite rock;the growth of cranies has been related with conjugate fractures in hinges of anticlines and salt structures.During Eocene epoch,salt lake ... |
