The inception of plate tectonics: a record of failure

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
The development of plate tectonics from a pre-plate tectonics regime requires both the initiation of subduction and the development of nascent subduction zones into long-lived contiguous features.

Distribution and Thermal Maturity of Devonian Carbonate Reservoir Solid Bitumen in Desheng Area of Guizhong Depression, South China

open access: yesGeofluids, 2017
The distribution of solid bitumen in the Devonian carbonate reservoir from well Desheng 1, Guizhong Depression, was investigated by optical microscope and hydrocarbon inclusions analysis. Vb and chemical structure indexes measured by bitumen reflectance,

Formation and Identification of Unresolved Complex Mixtures in Lacustrine Biodegraded Oil from Nanxiang Basin, China

open access: yesThe Scientific World Journal, 2014
A comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry (GC × GC/TOFMS) method has been developed for the formation and identification of unresolved complex mixtures (UCMs) in lacustrine biodegraded oils that with the same ...

Genesis and maturity identification of oil and gas in the Xihu Sag, East China Sea Basin

open access: yesPetroleum Exploration and Development, 2013
Based on the composition and stable carbon isotope ratios of condensate and natural gas in the Xihu Sag, East China Sea Basin, origin and maturity of the hydrocarbon gas, CO2, N2 and condensate are determined using multiple methods.
