Cleaning of fine asphaltite by oil agglomeration process
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020 In Turkey, asphaltite deposits are located in the Southeastern Anatolia region in the form of fleets around the Sirnak province and its environs. According to the research, although the lower thermal values of Sirnak asphaltites are between about 11–24 ...

Geobiology, Volume 16, Issue 5, Page 556-574, September 2018., 2018 Abstract In the deep biosphere, microbial sulfate reduction (MSR) is exploited for energy. Here, we show that, in fractured continental crystalline bedrock in three areas in Sweden, this process produced sulfide that reacted with iron to form pyrite extremely enriched in 34S relative to 32S.

Low Temperature Behavior of Asphaltite Modified Binders and Asphalt Concretes
Lecture Notes in Civil Engineering, 2020 Natural asphalts are often used as stiffeners to obtain hard bitumens. With the decrease of the global production of hard bitumens, the use of natural asphalts as stiffeners becomes increasingly interesting.
