沿裂隙产生的洋壳蚀变是使钾从海水中析出的主要原因。然而仅仅这种作用似乎还不足以维持海水中含钾的稳定状态。自生含钾矿物的形成也可能是导致从海水中析出的一个主要因素,至于离子交换和橙玄玻玻化作用,看来对海洋中钾的聚集所起的作用相对较小。 The alteration of the oceanic crust along the fissures is the main reason for the potassium precipitation from seawater. However, this alone seems not enough to maintain the steady state of potassium in seawater. The formation of authigenic potassium-containing minerals may also be a major contributor to the precipitation from seawater, and ion exchange and vitreous vitrification seem to play a relatively minor role in the accumulation of potassium in the oceans.
