STRATIGRAPHIC FRAMEWORK AND PETROLEUM GEOCHEMISTRY OLIGOCENE SOURCE ROCKS, NORTHERN SONG HONG BASIN

Biological marker geochemistry of selected oils and possible source rocks from central Alborz Basin

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...

Lake-Basin Type, Source Potential, and Hydrocarbon Character: an Integrated Sequence-Stratigraphic–Geochemical Framework

Regional Surficial Geochemistry of the Northern Great Basin

The regional distribution of arsenic and 20 other elements in stream-sediment samples in northern Nevada and southeastern Oregon was studied in order to gain new insights about the geologic framework and patterns of hydrothermal mineralization in the area. Data were used from 10,261 samples that were originally collected during the National Uranium Resource Evaluation (NURE) Hydrogeochemical an...
