摘要

The Mesozoic ecosystems, as of today, were subjected to various natural disasters like volcanism, earthquakes, floods, droughts and forest fires 1–4 . Wildfire has important influences on the environment, climate and biota, but our ability to understand these linkages in geologic past has been hampered by difficulties in identifying evidence for palaeowildfires and their proximate cause. The Gondwana System of the Allan Hills, southern Victoria Land, Antarctica offers a unique window to understand past volcanic activity. Continental volcanism was considered to be one of the major causes of forest fire during the Late Triassic of Allan Hills. The nature and source of forest fire can be addressed through thestudies of organic matter, geochemistry and fossil signatures 5,6 . Based on geochemical, palaeobiological and palaeowildfire evidences, many researchers have established volcanic activity in Antarctica during the Triassic 5,7–9 .
