The petrological, geochemical, and mineralogical compositions of the coal-hosted Jurassic uranium ore deposit in Yili Basin Xinjiang province, northwestern China, were investigated using optical microscopy field emission-scanning electron conjunction with an energy-dispersive X-ray spectrometer, as well powder diffraction, fluorescence, inductively coupled plasma mass spectrometry. coal is high volatile C/B bituminous rank (0.51–0.59% vitrinite reflectance) has a medium sulfur content (1.32%...

This study presents recently collected data examining the organic petrology, palynology, mineralogy and geochemistry of Gray Hawk coal bed. From Early Pennsylvanian, Langsettian substage, has been mined near western edge eastern Kentucky portion Central Appalachian coalfield. While is thin, rarely more than 0.5-m thick, it a low-ash yield low-S content, making an important local resource. The palynology dominated by Lycospora spp., contains diverse spectrum small lycopods, tree ferns,...

Abstract Non-pollen palynomorphs (NPPs) are ‘extra’ microfossils often found in palynology slides. These include remains of organisms within the size range pollen grains ( c. 10–250 µm), resistant to laboratory treatments used for preparation palynological samples. NPPs a large and taxonomically heterogeneous group living diverse environments. Taxonomically, they belong wide variety groups such as cyanobacteria, algae, vascular plants, invertebrates fungi. The aim this chapter is provide...
