1980年江苏省区调队将连云港市海州锦屏山锦屏组与朐山组之间的不整合命名为海州运动。代表早元古代与中元古代之间的一期区域构造运动(表1)。锦屏组与朐山组之间的接触关系,是一个长期以来一直争论的问题。其争论焦点在锦屏组底部的砾石成因问题。一种意见认为锦屏组底部的砾岩不是底砾岩,而是注入片麻岩或是混合岩化注入体经挤压而形成似砾状外形,两者之间不存在不整合面,是整合接触;另一种意见认为锦屏组底部砾岩是底砾岩,它与下伏朐山组混合花岗岩之间存在有沉积间断的标志,两者呈不整合接触。现在多数人同意后一种意见。根据近几年在这一带工作所取得的大量资料,并结合以往工作取得的成果,认为后一种观点更为可靠。
In 1980, the transfer team of Jiangsu Province named the unconformity between Jinping Formation and Jushan Formation in Jinping Mountain, Haizhou, Haizhou as Haizhou Movement. On behalf of the early Proterozoic and Mesoproterozoic period between the regional tectonic movement (Table 1). The contact between the Jinping and Dangshan formations is a matter that has long been debated. The focus of the debate is on the cause of the gravel formation at the bottom of the Jinping Formation. One opinion is that the conglomerate at the bottom of the Jinping Formation is not a base conglomerate, but rather an implanted gneiss or mixed petrified implants that are extruded to form a gneissic shape with no unconformity between the two The other opinion is that the conglomerate at the bottom of the Jinping Formation is a base conglomerate, and there is a sign of sedimentary discontinuity between it and the mixed granite in the Xiayanshan Formation. Both of them are in an unconformity contact. Most people now agree with the latter opinion. According to the large amount of information obtained in this area in recent years and the achievements made in past work, the latter point of view is believed to be more reliable.
