Cleaning of fine asphaltite by oil agglomeration process
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 ...

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
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.
