“…Such hydrocarbon distributions are diagnostic of organic matter derived from prasinophytes, marine algae such as Tasmanites (Azevedo et al, 2001). This organic facies has been reported to occur in several Devonian sources, including the Domanik Formation in the Tataria basin, just south of Timan-Pechora (Aizenshtat et al, 1998), the Keg River Formation of Alberta (Clegg et al, 1997), the Ohio Shale (Rimmer et al, 1993), and Bolivia (Peters et al, 1997).…”

“…32Shuicheng 2, has a S2 value as high as 352.5 mg HC/g rock. From the results of the analysis, it is also known that with the increase of vitrinite reflectance (Ro%), S2 generally shows a declining trend, which is similar to the findings of Rimmer et al (1993). After Rock-Eval pyrolysis, the samples in this study display little correlation between the S2 value and Ro% and Tmax, thus we were unable to discuss the reflectance suppression, maximum pyrolysis temperature suppression, and reworked sediments.…”

In this study, 26 samples from northwest Taiwan, 12 from Mainland China, 13 from Australia and 39 from literature were jointly examined to explore relationships among pyrolysis parameters, Vitrinite Reflectance Ro%, and Atomic H/C ratio. Samples of mixed high and low maturity coal were combined in proportions determined by the total quantity in the furnace prior to the Rock-Eval analysis and used to explore the correlation between the pyrolysis parameter, Tmax, and the vitrinite reflectance. These average values were then plotted against the corresponding Tmax results. The experimental results revealed that:(1) For low maturity coal samples that were mixed with different proportions of high maturity coal samples, the Tmax values fell within a range of low maturities. Alternativly, for samples containing the reworked sedimentary materials in the rock formation, the Tmax values were similar to the maturity of young material. (2) For sampling or Rock-Eval analysis of the high maturity materials, contamination with low maturity material should be avoided, even in very small amounts. (3) Afterproportional mixing, there was no evidence of a general linear relationship between the average of vitrinite reflectance, Ro%, and the corresponding Tmax value recorded. The atomic H/C ratio, as well as the BI, HI, QI, S1, and S2, generally decreases while the maturity (Tmax (o C); vitrinite reflectance Ro%) increases. The atomic H/C ratio decreases slightly from 1.1 to 0.7 while maturity increased from Ro 0.55% to 0.85%. Samples with atomic H/C ratio within this range show significant change in certain other geochemical parameters (eg. BI, HI, QI, PI, S1, S2, S1+S2, Tmax). Organic matter in the samples studied is of type II/III kerogen based on the relationship between HI and Tmax. The hydrocarbon potential per unit organic carbon (S1+S2/TOC) of the organic matter in this study to be approximately 100~380, similar to the potential of humic coal used in general gas and oil production. This shows that organic matter in an oil window of Ro%=0.55 and atomic H/C=1.1 have reached a certain maturity and hydrocarbon potential. Overall, when the atomic H/C ratio increases, the BI, HI, QI, S1, and S2 also show an increasing trend; therefore, these parameters and atomic H/C ratio show a certain correlation.

“…The Pine Mountain overthrust block which rides on the Chattanooga black shale at a thermal maturity sufficient for oil generation (Rimmer et al, 1993). The Upper Devonian Chattanooga extends well beyond the limits of the Pine Mountain detachment sheet, thus providing a regional source that might allow high pore pressure to exist simultaneously over the total length of the Pine Mountain thrust (Fig.…”

“…Thermal maturity in the southern Appalachian Mountains lagged where the Upper Paleozoic cover was thinner. The Pine Mountain block detached within the OhioeChattanooga shales when burial was sufficient to generate oil during the convergent phase of the Alleghanian Orogeny (Rimmer et al, 1993). This paper examines slip surfaces within four formations of the Middle and Upper Devonian section of the central Appalachian Basin of PA: the Marcellus, the Mahantango, the Burket/Geneseo and the Lock Haven Formations (Fig.…”
