Considering the development of organic-rich carbonate rocks, black shale and coal seams in the Permian in southern Sichuan Basin, it is considered that there is a possibility of paleo-oil reservoirs in the region. Keywords: sedimentary environment / carbonate slope / gas exploration / Permian /...
5.3.2.3 Inclusion of aromatic groups The embedding of aromatic rings within the π-medium of an organic D-π-A compound is generally considered to improve its SHG prospects. This is despite the fact that arene rings have their own well-defined delocalization energy, and this tends to have a...

Produced by the uptake of monomeric silicic acid, followed by dehydration and polymerization, the bioprocessing that creates these creatures was difficult to study because of the differential hardness of the silica mineral and the organic components. However, employing Ge(OH)4, as a substitute for ...
Organic carbon cycling and modern phosphorite formation on the east Australia continental margin: An overview. In: 11th and final international field workshop and symp of international geological coffelation programme project: phosphorites, Hertford Coll, Oxford, England, 87-117 [74] Holser, W. T...
Observations over the last few decades from a number of orogenic systems have highlighted the possible importance of tectonic exhumation, i.e., ductile thinning and normal faulting, in exhuming rocks once buried in high-pressure conditions. Taiwan is one of the few active orogens in the world ...
For example, shallow pore-water had NO3− concentrations between 3.38 mg/L and 9.92 mg/L (median, 6.11 mg/L), which were mostly lower than the coexisting shallow groundwater. As shown in Fig. 3, the distribution of major components of pore-water and groundwater in Zone 1 at different...
reveals such source rocks having the total organic carbon (TOC) values ranging from 2.3% to 8.1%, with an average of 4.1% (Fig. 3a), a hydrogen index (HI) ranging from 312 mg/g to 602 mg/g, with an average of 432 mg/g, and an organic matter type classified as II1-I (Fig. ...
