The lignite seam in the Jinsuo Basin of Yunnan Province. The Ciying Formation of Jinsuo Basin is mainly composed of siltstone, mudstone, sandstone, conglomerate, and lignite bed. There are four lignite layers (No. 1–4) from top to bottom, and the thickness of the No. 3 lignite layer studied is about 14~26 m. In this lignite seam, there are thick dark layers, thin pale layers, charcoal layers, and other sublayers. Charcoal samples are distinctly identifiable as charcoals originating from wildfire combustion. The palynology and plant residue studies of light and dark layers of lignite seam show that the light layer is dominated by herbal angiosperms with more gymnosperms, while the dark layer is dominated by woody angiosperms with a very low proportion of gymnosperms.
