9. Organic Geochemistry of Surface Sediments of the Sulu Trench/philippines
نویسندگان
چکیده
During cruise SO 58 of the FRG research vessel Sonne in 1988, surface sediments were collected from the deep waters of the Sulu Trench (Philippines) for organic geochemical investigations. The purpose of geochemical analyses of surface sediments is to obtain information on the nature and origin of gaseous hydrocarbons detected in these sediments and from this information to estimate the hydrocarbon potential of the Sulu Trench. In this paper molecular composition, gas concentrations, and stable isotope analyses, including both carbon and hydrogen, are used to characterize light hydrocarbons in marine surface sediments of the Sulu Trench. In addition, sulfate concentrations of interstitial waters and the redox potential of the sediment support gas geochemical interpretations.

Surface oil seeps from Alasht, Lapur and Jenesem share many compositional affinities including distributions and concentrations ofnormal alkanes, terpanes and steranes. These oils also show many similarities with that of Jurassic sediments (Shemshak Group, KlarizFormation) systematically sampled from the Galandrud Coal Mine. Recent geochemical studies in this area indicated that theShemshak Gro...

The mineralogy and geochemistry of Paleocene shales and interbedded siltstones in the southwestern of Ahar town (NW Iran) were studied by optical microscopy, XRD, SEM, XRF, and ICP-MS techniques. The mineralogical composition, mainly characterized by calcite, quartz, feldspar, dolomite, muscovite, magnesiohornblende, chlorite, illite, montmorionite, palygorskite, and koninckite, suggests relati...
