Abstract
Carbon isotopic ratios (delta(13)C) of isoprenoid hydrocarbons (isops) prod uced by heating(300-350 degrees C) of phytol were measured for understandin g diagenetic reaction of chlorophylls. C-19 isop was isotopically lighter t han the phytol at the early stage of the heating and lighter than C-20 isop regardless of heating temperature and time. Difference in delta(13)C betwe en C-19 and C-20 isops observed in this study was similar to that observed for some petroleum.
