It is found that the changes of N-alkane chain length distribution primarily reflect the seasonal temperature changes of the sediment source region in the study of organic geochemistry such as atmospheric dust and oceanic sediment. In order to maintain the viscosity of waxy covering and the water balance, studies suggested that higher plants mainly biosynthesize longer waxy lipoid in the warmer tropic areas while a priority of short chain lipoid compounds in the cooler temperate regions. From this, the average carbon chain distribution of N-alkane is a significant potential indicator in the study of paleoenvironment. ½ö¹©²Î¿¼ |
