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Javanese Hominid化石的古代，并为Jawa中直立的进化历史开发时间顺序的框架，并进行了以下研究。在中央和东贾瓦中的人类化石轴承形式检查其地层位置。2。使用Argon-40/Argon-39和Tephra样品上使用Argon-40/Argon-39和裂变轨道方法进行的Protographogrogroshophatographic分析和试验性约会，这表明有些Tephras对于临时性日期是实用的，但是由于碎屑矿物质污染物而导致的大量tephra层可能不可行。3。dyalll邻苯二甲酸酯（DAP）树脂的特性参考了其在裂变轨道约会中用作外部检测器的特性。还报道了使用此更有用的塑料探测器的裂变轨道约会的Zeta校准值。4。对中央和东贾瓦的原始化石沉积物进行了古磁研究，该研究为Sangiran地区提供了新的数据，并提供了其他数据。支持Mojokerto的先前结果的数据，以及Sambungmacan的初步数据。5。通过使用骨的多型骨使用骨的多元素分析，可以通过使用新的地球学方法来帮助从Jawa出发的某些人类化石的stratratigraphic分配，而没有足够的出处来源。与氟测定法相关。
