The conceptions of (Late Triassic) “Carnian Carbonate Productivity Crisis” or “Carnian Pluvial Event” were proposed by European geologists, based on the research on the Carnian of Alpine Region. The similar lithological change from carbonate rocks to black shale (or green shale and radiolarites), then terrigenous clasolite was widely seen in Eastern Tethys Region (SW China), which had not been paid attention to. It was deduced in this paper that the Carnian Carbonate Productivity Crisis was triggered by the orogeny occurred in Tethys region and by the megamonsoon effected by the global (especially Tethys) tectonic movements.
