Outline of Final Research Achievements

The result of biomarker analysis has distribution of n-alkane was from n-C13 to n-C21, bimodal peak in n-C16 and n-C17, and CPI (C13-21) value indicated the price of 0.79. The distribution of n-alkane is characteristic in the Inoceramus samples from Teshio Nakagawa Tanno-sawa which preservation was good. Individual carbon isotope compositions of each n-alkane were not felled below -30 per mill. The results of biomarker analysis of other Inoceramus samples consisted of the mixture of low carbon numbered (n-C13 to n-C21) alkane and n-C29 and n-C31 alkane. PMI and crocetane, were not detected. The fatty acid composition was characterized by excel C16 fatty acid and its carbon isotope composition higher than-30 per mill. Perylene was a dominant compound in the PAH fraction extracted from Inoceramus samples. Thus the special biomarker which determines chemosynthetic community was not detected, but a possibility was indicated focusing on a result of the biomarker analysis.
