对地处新构造运动强烈地区的合恩晚第四纪上升珊瑚阶地三条剖面的样品分析表明:造礁珊瑚和礁灰岩的不稳定矿物成分的转化和成岩强度与构造运动密切相关,而局部气候状况似乎不起主导作用。上升速率较低地区的珊瑚骨骼和礁灰岩的方解石化普遍、彻底,孔隙中方解石胶结物含量大仅存文石胶结物残余;与之相反,构造上升速率高的地区虽有较高的年降雨量,但珊瑚和礁灰岩转化不普遍,方解石胶结物含量低且保存大量文石胶结物。这是因为构造上升决定了阶地的区域地貌特征,影响阶地地形起伏,从而控制了在生物礁成岩变化中起主要作用的水动态条件。
The analysis of samples from three sections of the Coral Terraces in the late Huanian Late Quaternary Period in the area with strong neotectonic activity shows that the transformation and diagenic intensity of the unstable mineral components in reef-reef and reef limestone are closely related to the tectonic movement, Climate conditions do not seem to play a leading role. The calcareous formation of coral skeletons and reef limestone in areas with relatively low rates of increase is widespread and complete with large calcite cements remaining in the pores remaining aragonitic cements. In contrast, the areas with high tectonic rates of rise have higher years Rainfall, but coral and reef limestone conversion is not common, calcite cement content is low and save a large number of aragonite cement. This is because the tectonic upwelling determines the terraform features of terraces and affects terraces and undulations, thus controlling the hydrodynamic conditions that play a major role in diagenetic diagenesis.
