Origin and Distribution of Large Asphaltite in South China [PDF]
Large quantities of Triassic solid asphaltite were discovered in the Guangyuan area, northwest Sichuan. The asphaltite is formed in layers with a vertical thickness between 0.3 and 2.8 m and is stably distributed with intrusive contact with surrounding rocks. This study aims on the genesis and distribution of asphaltite through trace element, biomarker,

Investigation of surface properties of Avgamasya asphaltite
Abstract Surface properties of Avgamasya asphaltite were investigated by the adsorption method using N 2 and CO 2 gases. In order to see the effect of ash content and pyrolysis temperature on the surface properties of asphaltite, samples were washed with 15% (v/v) HCl to reduce the ash content, and then pyrolyzed in a nitrogen atmosphere between ...

Investigation of the cleanability of asphaltite by flotation
Abstract Southeastern Anatolia Region of Turkey/Sirnak asphaltites centers are located in and around large reserves in coal mines. Due to the high ash and sulfur content of asphaltite coal, it is important to use it by cleaning with enrichment methods, in terms of solving environmental problems and increasing energy quality.

Ion irradiation of asphaltite as an analogue of solid hydrocarbons in the interstellar medium [PDF]
We present the results of experiments of low temperature ion irradiation of pure asphaltite samples and those covered with water ice layers. Asphaltite (a natural bitumen) was used as an analogue of carbonaceous interstellar grains on which water- rich icy mantles can be formed in the dense and cold phases of the interstellar medium.

Organoporosity evaluation of shale: a case study of the Lower Silurian Longmaxi Shale in southeast Chongqing, China. [PDF]
The organopores play an important role in determining total volume of hydrocarbons in shale gas reservoir. The Lower Silurian Longmaxi Shale in southeast Chongqing was selected as a case to confirm the contribution of organopores (microscale and nanoscale pores within organic matters in shale) formed by hydrocarbon generation to total volume of ...
