THE FEATURES OF THE SPORO-POLLEN ASSEMBLAGE AND ITS GEOLOGICAL SIGNIFICANCE IN CAVE DEPOSITS IN ANTU COUNTY,JILIN PROVINCE
【摘要】 <正> 洞穴位于安图明月镇东南2.5公里的石门山村,东径128°55′35″,北纬43°5′17″。1964年作者与吉林省博物馆等单位人员对洞穴进行了清理,获得一批哺乳动物化石和一枚古人类牙齿化石。1979年我们又对洞穴进行孢粉取样,经分析获得非常有意义的结果。 (一)洞穴的地貌、第四纪地质概况
【Abstract】 The cave is situated at Shimenshan village 2.5 km southeast of Mingyue Town, Antu County, Jilin, at long. 128°55′35″E and lat. 43°5′17″N. Sporo-pollen analyses show that there are altogether 23 families and genera. The features of the sporo-pollen assemblage show that at the time when the assemblage occurred the landscape of vegetation around the cave was the one of forest-steppe composed of Pinus, Picea, Artemisia, Compositae and Selaginella and that the climate was cold and dry.The fossils of Manmuthus-Coelodonta obtained from the same horizon have been determined to havea a C14 age of 23700-35400 yr. B. P. So the geologic age is assigned to latest Pleistocene and the cultural age to the late Paleolithic age.
