The origin of Middle Jurassic evaporites in the Qamdo Basin is still controversial because palaeontological studies have reported that they have both marine and continental characteristics. The 87Sr/86Sr ratios of the gypsum in the Middle Jurassic Dongdaqiao Formation in the Qamdo Basin range from 0.707602 to 0.708163, which are higher than
Preliminary U/Th dating and the evolution of gypsum
The origin and the evolution of giant selenite crystals in Naica caves, together withthe understanding of their growthmechanisms, is one of the aims of the international multidisciplinary research, called the “Naica Project”. In this context, the exact timing of when the gypsum nucleation started and whether its growthhas been constant over time, have
The Role and Implications of Bassanite as a Stable
2012年4月6日 The precipitation of calcium sulfate phases (gypsum, bassanite, and anhydrite) from seawater led to the formation of numerous ancient and modern evaporite deposits on Earth (1, 2) and to abundant gypsum and bassanite on Mars.Today the precipitation of gypsum poses a serious economic threat through the formation of
Thermogravimetric Characteristics and Pyrolysis Kinetics of
In the present study, the pyrolysis behavior of Nigerian oil sands was investigated using thermogravimetric analysis. This was done with the aim of deriving kinetic models that can be relevant in the development of the natural resource. The effects of different heating rates (10, 20, and 30 °C/min) on oil sand pyrolysis were studied. The results of the study
