For the past 20 years the modern hu- man origins debate has received a significant amount of attention in paleoanthropological research. Primar- ily supported by the evidence of earlier dates of anatomically modern human fossils and genetic studies, the “Out of Africa” hypothesis is based on the belief that the ancestor of all modern humans, in- cluding modern Chinese, came from Africa. The op- posite hypothesis “Mutiregional evolution” proposes that continuous evolution occurred on a regional scale, for which human paleontology offers strong support. However, due to the paucity of hominid fos- sils in China between 100 and 50 ka, support to the latter hypothesis is currently weak. This is a report here of five human fossil teeth, and associated stone tools and mammal fossils from a newly discovered cave site, Huanglong Cave, located in Yunxi County, Hubei Province, China. Preliminary studies indicate: (1) the morphological features of the human fossils resemble those of late Pleistocene human fossils from China; (2) the stone tools display patterns of both the southern and northern Paleolithic cultures of China; (3) the mammal fossils represent the “Ailuro- poda-Stegodon” faunal unit which lived in southern China throughout the Pleistocene. ESR and U-series dating on animal teeth and a stalagmite derived from the same layer as the human teeth indicate two possible ages: 103±1.6 ka and 44±12.5 ka. In addi- tion to other evidence presented here, it is believed that hominid occupation of the cave was likely around 100 ka. If this age is further substantiated, Huanglong Cave will be the first late Pleistocene hominid fossilsite in China where anatomically modern humans lived about 100 ka. The human fossils and other re- lated materials from Huanglong Cave will provide important information for research on the origin of modern Chinese.

Six granite samples were collected from six difference elevation locations at the Hua Shan in a main ridge of the Qinling Mountain. Apatite and zircon separated from these six samples were dated by the fission track technique. An assessment of the Cenozoic uplift or exhumation rate was obtained from the altitude difference of sampling samples dated by fission track, and from the difference of fission track dates of both apatite and zircon for a sample. The preliminary results suggest that the beginning of uplift of the Hua Shan was as early as 68.2 MaBP and the uplift rates for different periods are 0.02-0.19 mm/a (from the elevation difference) or 0.12-0.16 mm/a (from two mineral fission track dates). The average uplift rate is 0.12 mm/a (from the elevation difference) or 0.14 mm/a (from two mineral fission track dates). The uplift of the Hua Shan might accelerate since (17.8±2.0) MaBP, and the average uplift rate is about 0.19 mm/a.

The calcium carbonate coats on stones developed in soil on the geomorphic surfaces of coarse clastic sediments in arid-semiarid regions contain evident information of age. The thickness of coats can be used not only as a good age indicator for the geomorphic surfaces but also coats themselves can be directly used as dating materials in the ESR method. Through measuring the thickness of carbonate coats on stones in soils on the alluvial terraces in the mouth of the Heishanxia gorge of the Yellow River and ESR dating of layers separated from the carbonate coats, the average of accumulation rates of the thickness of carbonate coats on stones since 1.57 Ma was calculated to be 0.10 mm/ka in the studied area, and a regression equation between carbonate coat thickness and age was also generated. From these research results, ages of T2-T11 terraces of the Yellow River in the studied area were systematically determined, and their values are in turn 18 ka, 94 ka, 139 ka, 215 ka, 305 ka, 410 ka, 495 ka, 742 ka,

对于距今老于20万年的碎屑沉积物,目前还没有一种成熟可靠的测年技术。根据实验模拟、理论推测和少量实际测量表明,如果采用适当的电子自旋共振(ESR)信号中心和测量参数,ESR可以测定含石英沉积物最后一次曝光的年龄,其测年范围可望覆盖整个第四纪。因此,ESR测定第四纪沉积物具有极大的发展潜力,并已开始被研究第四纪、新构造和环境变化等方面的国内学者所接受。但是,目前给出的ESR年龄的可靠性有多大、与真实年龄之间有多大的差异等仍属未知。目前ESR测定沉积物年龄仍是一种未完全成熟的测年方法。

第四纪碎屑沉积物测年，尤其是对老于距今二十万年以上的样品，是目前第四纪年代学中的难点。ESR是可望能够直接测定这类样品的测年方法之一。本文详细测量了从不同地区采集的现代沉积样品石英E’心的吉剂量值，其结果都小于4000Gy。这与实验室光晒退结果推测的并不一致。可能E’心存在目前还没有被了解的适合测年的内在原因，对于E’心能否真的用于沉积物测年有待于进一步的研究。
