During ten years from 1994 to 2004, 1563 stream sediment samples were collected in the northeastern parts of Aichi Prefecture. Some of the samples have been already measured for Al, Ti and P by inductively coupled plasma atomic emission spectrometry (ICP-AES), and for K, Na, Fe, Ca, Mg and Mn by atomic absorption spectrometry (AAS) and their data have already been published. In this study, however, the sediment samples were re-measured for major-element concentrations by XRF, and the additional samples were re-measured for major-element data including Si. The data for all of the sediments together with geological information are presented here for database to make a geochemical map of the northeastern areas of Aichi Prefecture. Furthermore, we discuss on difference between data by ICP-AES and AAS and, those by XRF. The geochemical and geological discussions on the major elements will be made elsewhere, and the data of trace-element concentrations of the sediments by neutron activation analysis will be offered soon., 国立情報学研究所で電子化したコンテンツを使用している。}, pages = {25--67}, title = {Database for geochemical mapping of the northeastern areas of Aichi Prefecture, central Japan ^ XRF major element data of stream sediments collected in 1994 to 2004 -}, volume = {52}, year = {2005} }
