The alternative changes of paleoenvironment favored the formation and imbedding of brine , which is the source of salt - water intrusion ; and the paleochannel that formed during regressive of sea level is the path of salt - water intrusion 海进时期,大面积的滨海平原被淹没,在近海平原洼地滞留的海水经过蒸发、浓缩变为卤水,成为咸水入侵的物源;海退后陆源碎屑在滨海地区沉积形成了巨厚的古河道砂层。
