Geochemistry of trace elements in Chinese coals: A review of abundances, genetic types, impacts on human health, and industrial utilization
TL;DR: The background values of trace elements were dominated by sediment source regions in coal-bearing strata in China as mentioned in this paper, and the genetic types for trace-element enrichment of Chinese coals include source-rock- controlled, marine-environment-controlled, hydrothermal-fluid-controlled (including magmatic-, low-temperature-hydrothermalfluid-, and submarine-exhalation-controlled subtypes), groundwater-controlled and volcanic-ash-controlled.
