Effect of igneous intrusive on coal microconstituents: Study from an Indian Gondwana coalfield
Shinjini Sarana,Ratan Kar +1 more
TL;DR: Petrological and palynological analyses of coals from two bore-holes, intruded by an igneous body (dolerite dyke), reveal characteristic changes due to thermal alteration.

Spectral manifestations of coal metamorphism: Insights from coal microstructural framework
TL;DR: In this article, the microstructural framework of coals from the Raniganj and the Jharia Basins as well as from the Himalayan fold-thrust belts of Sikkim, India, by vitrinite reflectance, Raman spectroscopy, Fourier transform infrared, and X-ray photoelectron spectrographs was investigated.

Melting on Fault Planes During Large Earthquakes
Dan McKenzie,James N. Brune +1 more
TL;DR: In this paper, it is shown that the temperature on the fault plane can reach the melting temperature for short periods if the slip is sufficiently large and the displacement required to produce melting depends on the magnitude of the regional stress and also on the friction stress.

Organic maturation studies and fossil fuel exploration
TL;DR: The main aim of Organic Maturation Studies and Fossil Fuel Exploration is to provide a platform for current research, developments, applications and discussion on organic maturation of sedimentary organic matter presented against the ever increasing requirements of petroleum exploration as discussed by the authors.
Journal ArticleDOI
Heating during thrust faulting in the rocky mountains: friction or fiction?
TL;DR: In this article, the authors measured the levels of organic maturation below and within shear zones of thrust faults in the Rocky Mountains and revealed no general thermal metamorphism that can be attributed to faulting, with the exception of very localized areas.
