TL;DR: New discoveries of hot spring deposits including geyserite, sinter terracettes and mineralized remnants of hot springs pools/vents are presented, all of which preserve a suite of microbial biosignatures indicative of the earliest life on land.

TL;DR: The characteristics of coal-derived UCs are a function of the rank and type of the coal, as well as the size of the feed coal and the combustion conditions as discussed by the authors, and the nature of UCs resulting from vitrinite is dependent upon the coal rank.

TL;DR: In coal and coal-bearing sequences, the main primary minerals in volcanic ash are high-temperature quartz, plagioclase, sanidine, zircon, apatite, monazite, micas, rutile, and anatase as mentioned in this paper.

TL;DR: In this article, the authors reviewed the current knowledge and understanding of coal burst phenomena and identified future research needs and priorities for the coal burst management and control An enhanced understanding of the driving mechanisms is essential for delivering reliable coal burst risk management and mitigation strategies.

TL;DR: In this article, the abundance, modes of occurrence, and origin of rare metals in three Lopingian coals (LL5-K3, CG3-K6, and CG1-K7 Coals) from the Yishan Coalfield, Guangxi Province, southern China were investigated.
