Origin and Distribution of Large Asphaltite in South China [PDF]
ACS Omega, 2020 Large quantities of Triassic solid asphaltite were discovered in the Guangyuan area, northwest Sichuan. The asphaltite is formed in layers with a vertical thickness between 0.3 and 2.8 m and is stably distributed with intrusive contact with surrounding rocks. This study aims on the genesis and distribution of asphaltite through trace element, biomarker,
