Organic geochemistry

As high latitude regions continue a decades-long trend of warming at roughly twice the rate of the global average, an understanding of their climatic histories becomes increasing important for predicting their future. Organic molecular proxies preserved in lake sediment archives…

Source rock and crude oil samples collected from the Murzuq Basin, S.W. Libya have been investigated by a variety of organic geochemical methods, including Rock-Eval pyrolysis (RE), gas chromatography (GC), gas chromatography mass spectrometry (GCMS), and graptolite reflectance.…

The geochemical composition of thirty two (32) oil samples in the Central Sumatra Basin (CSB) were determined by gas chromatography (GC), gas chromatography coupled with mass spectrometry (GC-MS) and gas chromatography isotope ratio mass spectrometry (GC IR-MS). The carefully se…
