For the terrigenous
DOM sources, HIX is the proxy for the humification extent.
However, the importance of terrigenous
material (clay), as well as the probable slope of the basin floor, increases successively towards the western margin of the craton, towards the Caledonide mountain range (Jaanusson 1982).
Sand friction is composed of carbonate material eroded from coralline terraces and terrigenous
detrital material transported by seasonal wadis during flood event and contains high concentration of Ca, Mg and Sr, whereas, trace element concentrations are positively correlated with mud, Fe, Al, Ti, Mn, Cu, Ni, Co, Cr, V and B contents.
Organic matter including mineral nutrients and aquatic organisms can increase bioproductivity, while terrigenous
and aquatic organic matters determine kerogen types .
The low influx of terrigenous
sediments helped in carbonate deposition in the form of Zaluch group (Mertmann, 2003).
The REE signatures in limestones can be affected by some mechanisms such as input of terrigenous
particles, Mn- and/or Fe- oxides, hydrothermal activities, diagenetic processes, and mineral phases such as phosphates (Elderfield et al., 1990; Bau et al., 1996; Byrne et al., 1996; Bolhar et al., 2004; Tang et al., 2013; Madhavaraju et al., 2016, 2017).
Atmospheric particles are complex mixtures of contributions from natural emission (marine, terrigenous
) and anthropogenic sources (Seinfeld & Pandis, 1998; Azri, Maalej, & Medhioub, 2000; Allen, Nemitz, Shi, Harrison, & Greenwood, 2001; Muhammad, I.
Clastic Depositional Systems: Applications to Fossil Fuel and Groundwater Resources, Springer Verlag, Berlin, Germany, 2nd edition, 1996.
Calcite and terrigenous
materials are not affected.
Located at the northern tip of Chilean Patagonia, the ISC receives freshwater inflow from fluvial and/or glacial origin (Calvete & Sobarzo, 2011) and terrigenous
sediment supply (Silva et al., 2011).
The carbon number distribution is [C.sub.11]~[C.sub.38], the parity advantage is not obvious, the maximum carbon number is [C.sub.17]~[C.sub.21], and [summation] [C.sub.21.sup.-]/[summation][C.sub.21.sup.+] ranges from 0.77 to 2.47 (Table 2), indicating that the crude oil is composed by hydrobiont and terrigenous
plants and the aquatic bacteria play an important role.
