The present research was designed to reconsider the antiquity of the Javanese hominid fossils and to develop a chronological framework for the evolutionary histories of Homo erectus in Jawa, and the following investigations have been made.1.Series of sediment samples for dating have been collected with checking their stratigraphic positions from hominid fossil bearing formatins in Central and East Jawa.2.Petrographic analyses and pilot dating using argon-40/argon-39 and fission-track methods on the tephra samples, have shown that some tephras are practical for chronometric dating, but a large number of tephra layers may not feasible for dating due to detrital mineral contaminants.3.The properties of diallyl phthalate (DAP) resin were studied with reference to its use as an external detector in fission-track dating. And also zeta calibration values for fission-track dating with this more useful plastic detector have been reported.4.A paleomagnetic study was carried out on hominid fossil bearing sediments in Central and East Jawa, which has given new data for the Sangiran area and additional data supporting the previous results on Mojokerto, and also preliminary data for Sambungmacan.5.Stratigraphic allocation of some hominid fossils from Jawa without sufficient context for provenance has been assisted by using a new geochemical approach by multielement analyses of bone using inductively coupled plasma spectrometry, in company with the fluorine assay.

本研究旨在重新考虑爪哇人科化石的古老性，并为爪哇直立人的进化历史建立一个年代框架，1.在爪哇中部和东部含人科化石地层中采集子一系列用于测年沉积物样品，并核对其地层位置。2.岩相分析和氩离子定年试验。40/Ar-39法和裂变径迹法对火山灰样品的测年结果表明，某些火山灰可以用于测年，但大量火山灰层可能由于碎屑矿物的污染而无法用于测年。3.研究了邻苯二甲酸二烯丙酯（DAP）树脂作为裂变径迹测年外部探测器的性能。4.对爪哇中部和东部含原始人类化石的沉积物进行了古地磁研究，为Sangiran地区提供了新的数据，并为Mojokerto以前的结果提供了额外的数据。5.利用一种新的地球化学方法，对爪哇地区一些没有充分物源背景的人科化石进行了地层定位通过使用电感耦合等离子体光谱法对骨进行多元素分析，并结合氟含量测定。
