Isotope organic geochemistry
TL;DR: The present-day state as well as the history of isotope organic geochemistry is reviewed in this article, where theoretical aspects of fractionation in a system of complex organic molecules, fractionation of carbon isotopes in the biosphere, isotopes as applied to study the transformation of organic matter, geochemistry of oil and gas, evolution of the carbonate-organic carbon system and aspects of astrobiology are considered.

A review on microbial synthesis of hydrocarbons
TL;DR: Comparisons of comparative data on the intracellular hydrocarbons of different microorganisms (cyanobacteria, aerobic and anaerobic bacteria, yeasts, and mycelial fungi) suggest that Mechanisms of the hydrocarbon synthesis appear to be different in various microorganisms.

Using Variable Ionization Energy Time-of-Flight Mass Spectrometry with Comprehensive GC×GC To Identify Isomeric Species
TL;DR: In this paper, the fragmentation patterns of molecules in mass spectrometers using electron impact ionization at 70 eV can be useful for molecule identification, provided a match is available in a published EI MS library, but are indistinguishable for many isomeric organic compounds.

Biogeochemistry of the 1640 Ma McArthur River (HYC) lead-zinc ore and host sediments, Northern Territory, Australia
TL;DR: In this paper, the formation of the McArthur River lead-zinc deposit involves thermogenic or biologic oxidation of sedimentary organic matter, the products of which generated a massive stratiform sulfide ore body, and secondary carbonate and silica precipitates formed within the sediment pile down the flow pathway and above the reaction zone.

Sedimentation, distribution and diagenesis of organic matter in a recent carbonate environment, Abu Dhabi, U.A.E.
TL;DR: In this article, the authors defined organo-sedimentary facies based on geochemical and sedimentological criteria and constructed an organosedimentary sequence which expressed the Holocene sedimentary record involving a transgressive and a regressive sequence.

Phospholipid studies of marine organisms: III. New phospholipid fatty acids fromPetrosia ficiformis
TL;DR: The fatty acyl components of the phospholipids from the spongePetrosia ficiformis consisted predominantly of branched, especially iso and anteiso acids, which are the hitherto unknown Z,Z-25-methyl-5,9-hexacosadienoic and Z, Z-24- methyl-5-9- hexacosatrienoic acids.
