结果表明:显生宙以来海水组分发生变化,经海相非骨骼灰岩和钾盐蒸发岩矿物学研究,发现这两种沉积岩长期以来连续变化,在"文石海"是MgSO4型蒸发盐,在"方解石海"是KCl型蒸发盐,从白垩纪晚期、第三纪早期的底部石盐溴含量及矿物学特征表明,此时处于"方解石海",古海水组分的特点是造成缺硫酸盐型钾盐矿床形成的物化基础;通过NaCl-KCl-MgCl2-H2O和NaCl-KCl-MgCl2-CaCl2-H2O两个体系相图的分析认为,当时所形成的成钾原始体系母液是高镁、低钾氯化物型的卤水,在母液蒸发过程中,由于原始海侵母液与残余高镁母液的掺杂作用,致使结晶路线直接从氯化钠区到E点母液或光卤石与氯化钠共饱线上,而没有通过氯化钠和氯化钾的共饱线,因而在矿体中氯化钾相很少或几乎不存在,由于外界CaCl2型水体的掺杂,使成钾母液进入光卤石相区,随着蒸发的进行,最终形成溢晶石矿物。
