In many regional geochemical studies of prolific basins, thermally-altered fluids generated from deep, post-mature sources mixed with normally-mature black oil from mature sources have gone unrecognized, uncharacterized, and the extent to which those

About 34 million years ago, Earth's climate shifted from a relatively ice-free world to one with glacial conditions on Antarctica characterized by substantial ice sheets. How Earth's temperature changed during this climate transition remains poorly u

Recent molecular phylogenetic and molecular clock data both suggest a pre-Mesozoic age for the divergence of the angiosperm lineage from other seed plants, greatly predating the confirmed fossil record of the angiosperm crown group. In addition, mole

Our analysis of lipid molecular fossils from a Lake Titicaca (16° S, 69° W) sediment core reveals distinct changes in the ecology of the lake over an ∼25,000-yr period spanning latest Pleistocene to late Holocene time. Previous investigations hav

Controls on oil family distribution in tectonically complicated, nonmarine, petroliferous basins are commonly difficult to isolate because of the varying ages of potential source rocks, the complex assemblage of organic-rich sedimentary facies, and t

New bulk and molecular organic geochemical analyses of source rock and oil samples from Mongolia indicate the presence of lacustrine-sourced petroleum systems in this frontier region. Samples of potential source rocks include carbonate, coal, and lac

Llanos Basin oils have been commonly attributed to the prolific Upper Cretaceous age source formations outcropping in the Eastern Cordillera. Recently, however, variable oleanane indices have been reported for Llanos oils, suggesting a contribution f

Our organic geochemical study of oils from the northern Qaidam basin defines a family of genetically related oils that contain biomarkers indicative of source rocks deposited in Tertiary hypersaline, anoxic lacustrine settings. Although Cenozoic outc

The Qaidam basin is a nonmarine, petroliferous basin on the northeastern margin of the Tibet Plateau. Potential source rocks are reported from Tertiary saline lacustrine deposits and Jurassic freshwater lacustrine or terrestrial strata. The Jurassic
