Definition Utilization of the rhenium–osmium (Re–Os) radioisotope geochronometer to (1) determine the depositional age of organic-rich rocks (ORR), (2) establish the Os isotope ( 187 Os/ 188 Os) composition of sedimentary successions, and (3) date the timing of hydrocarbon (oil) ...
Why is coal an organic sedimentary rock? Why do plants produce psychoactive compounds? Why is the Calvin cycle considered a dark reaction? Why is bacteria considered a pioneer species? How do pesticides affect humans? Explain. Explain why triglycerides are nonpolar. ...
Organic petrology contributes to the analysis of organic facies, to the assessment of depositional conditions of organic matter and to the definition of sedimentary paleoenvironments. It is also a fundamental tool in diagenesis and in very low grade metamorphism investigations, in the evaluation of ...
The emission sources of PAHs can be divided into natural andanthropogenic sources. Natural sources include forest fires,volcanic eruptions, synthesis of bacteria and algae, oil seepage, andsedimentary rockerosion. Anthropogenic sources can be classified into stationary and mobile sources. Stationary sources...
However, by definition, CaExch only represents Ca2+ engaged in outer sphere interactions. The selective chemical extraction of the inner sphere Ca pool, corresponding to pyrophosphate extractions for Al and Fe in acidic soil environments (Bascomb 1968; Parfitt and Childs 1988; Rasmussen et al. ...

From the definition of nodes, the Y-type refers to the termination of a fracture trace against another one and the I-type represents an isolated end, while at X-type there is no termination for the fractures, and the number of traces NL is given by:NL=(NI+NY)/2=364 This NL is ver...
TPH:FA (which explicitly includes a TPH-like component and the FA-like component) differs in definition from β:α, a proxy for autochthonous microbially-derived DOM, which describes humic-like components of varying expected bioavailability (β defined as Exmax: 310–320 nm and Emmax: 380–420...
