High molecular weight hydrocarbons: A new frontier in Organic Geochemistry

AbstractFor the past two decades organic geochemistry has been concerned mainly with compounds in the carbon number range up to C40 as a result of various analytical limitations. The availability of gas chromatographic columns with upper temperature limits of 48OºC, or even higher, has opened a new area for geochemical research, that of high-molecular-weight compounds above C40. This paper reviews some recent advances in this field with particular reference to hydrocarbons and speculates on possible origins for some of the compounds.
