| 摘 要： | 1980年夏,作者在河北省阳原县泥河湾古湖区进行考察时,在虎头梁剖面上部的湖相层中发现了叠层石夹层。对所采集样品进行了制片、酸磨、光学显微镜与电子探针等研究。由于酸磨方面的技术原因或其它原因,尚未见叠层石内部的藻类化石。

| Abstract: | The stromatolites found in Nihewan area were dated back to middle Pleistocene in con- sideration of their locality,horizon,shape,structural characteristics,style and the difference between the chemical compositions of light and dark laminae and the chronology.The stroma- tolites were determined to be formed in an ancient environment of shallow and clear water with slow sedimentation according to the characteristics of ecology and palaeotaphonomy of them. |
