The major types of Terrestrial source rocks and the peculiarities of biological marker composition of Terrestrial oils in China
Journal of Southeast Asian Earth Sciences, 1991Co-Authors: Fu Jiamo, Sheng Guoying, Peng Pingan, Xu Jiayou, Huang YongsongAbstract:Abstract Most crude oils found so far in China are of Terrestrial Origin, ranging in age from Carboniferous to Paleogene. The biomarker compositions of these oils are controlled by the nature of their related source rocks. The biomarkers of oils from large fresh-water paralic lake basins are characterized by the absence or low content of triterpanes of higher plant Origin. The biomarkers of the oils from fresh-brackish lacustrine clastic formations in fault-subsidence basins have abundant compounds of Terrestrial Origin. The oils generated from salt lake evaporite-clastic formations in fault-subsided basins have a rather high content of phytane, heterocyclic compounds and gammacerane, while the oils from lagoonal-lacustrine volcano-clastic formations in intermontane basins contain abundant isoprenoids and carotanes. The immatural oils are also discussed with regard to the special composition of biomarkers and their exploration significance.

Insect remains from an Alleröd peat at Lake Bysjön, South Sweden
Boreas, 2008Co-Authors: Geoffrey LemdahlAbstract:An insect fauna in a peat layer from Lake Bysjon, South Sweden, 14C-dated to 11,200 ± 100 B. P. is described. The recorded insects indicate that the peat is of Terrestrial Origin and that it was formed in a subarctic environment.

Influence of partial substitution of dietary marine Origin feedstuffs by a mixture of extruded pea seed meal and animal Origin feedstuffs on fatty acid composition of fillet in sea bass (Dicentrarchus labrax)
Italian Journal of Animal Science, 2016Co-Authors: M. Scerra, F. Foti, P. Caparra, C. Cilione, Laura Violi, Piero Lamanna, Luigi ChiesAbstract:AbstractThe aim of the study was to investigate how partial replacement of marine Origin feedstuffs by a mixture of Terrestrial Origin (extruded pea meal, feather meal, spray-dried blood meal, soybean oil) feedstuffs affects the fatty acid composition of European sea bass fillet. Two experimental diets were formulated for the better growth of sea bass with an initial mean weight of 30 g in sea cages placed at 2500 m from the coast. The marine diet (MD) diet included 45% of marine Origin feedstuffs, containing 30% of fish meal (herring), 10% of fish oil (anchovy) and 5% of krill meal, while Terrestrial diet (TD) diet included 20% less of marine Origin feedstuffs replaced by a mixture of Terrestrial Origin feedstuffs. The experimental diets did not affect growth performance and food conversion ratio in sea bass. The contents of EPA and DHA resulted lower in tissues of fish fed diet with the higher levels of Terrestrial Origin feedstuffs. Consequently, also the levels of total n-3 PUFA were lower in muscle o...

Influence of partial substitution of dietary marine Origin feedstuffs by a mixture of extruded pea seed meal and animal Origin feedstuffs on fatty acid composition of fillet in sea bass (Dicentrarchus labrax)

The experimental diets did not affect growth performance and food conversion ratio in sea bass. The contents of EPA and DHA resulted lower in tissues of fish fed diet with the higher levels of Terrestrial Origin feedstuffs. Consequently, also the levels of total n-3 PUFA were lower in muscle of fish of this group; conversely total n-6 PUFA resulted in higher levels. According to the effect of treatments on both total n-6 and n-3 PUFA, the ratio of ∑n-6/∑n-3 FA was higher in fillet of sea bass fed TD diet, maintaining anyway values sufficiently acceptable for a healthy diet according to Brennal et al

Trace element geochemistry of crude oils and condensates from South African Basins
Marine and Petroleum Geology, 2015Co-Authors: Akinsehinwa Akinlua, A. Sigedle, T. Buthelezi, O. A. FadipeAbstract:Abstract Crude oil and condensates samples from Bredasdorp and Orange Basins, South Africa were analyzed for trace elements using inductively coupled plasma – optical emission spectrometry. The oil and condensate samples were analyzed to classify the oils into family and to determine the Origin of the oils and depositional environment of organic matter that yielded the oils using trace elements. The concentrations of the elements (Co, Cr, Cu, Fe, Mn, Ni, and V) determined ranged from 0.10 to 7364.7 ppb. Iron is the most abundant element in the samples while cobalt is least abundant. Both concentrations and ratios of nickel and vanadium showed two main families of oils; oils of marine Origin and oils of Terrestrial Origin. Oil samples from the Orange Basin are mainly of marine source and their organic matter were deposited under anoxic conditions. Most of the oil samples from the Bredasdorp Basin are of marine Origin with a few samples having Terrestrial Origin. Cluster analysis also classified the oil and condensate samples from the two basins into two main families of marine and Terrestrial sources.
