Abstract
The marine oils derived from Cambrian-Ordovician source rocks of Lower Palaeozoic al-ways contain low-middle wax in Tarim Basin. The kerogen of bower Palaeozoic marine strata are mainly composed of amorphous matter decomposed from bacteria and algae, and are high mature, There is a higher content of C+21n-alkanes in the pyrolysates by kerogen's PY-GC analysis, Associating with petroleum migration, we can conclude the genesis model of middle wax marine oils,in which the bacterium source in high maturity is a main factor, And the model breaks through the concept that the oils with higher wax are only derived from organic matters of high plants.
