Environmental changes in the Late Ordovician?early Silurian: Review and new insights from black shales and nitrogen isotopes
Original language description
The Late Ordovician (Katian-Hirnantian) through earliest Silurian (Rhuddanian) interval was a time of varying climate and sea level, marked by a peak glacial episode in the early-mid Hirnantian. Synthesis of recently published data permits global correlation of at least two cycles of glacial advance and retreat with a distinct interglacial period that is recognizable in sequence stratigraphic and chemostratigraphic records worldwide. A period of warming and sea level rise during the late Katian is marked by the widespread occurrences of oceanic anoxia in paleotropical and subtropical localities, mostly confined to regions of inferred upwelling and semi-restricted marine basins. Nitrogen isotope data show that the regions of oceanic anoxia were marked by intense water column denitrification in which cyanobacteria were the principal source of fixed N. In the overlying peak glacial interval of the Hirnantian, sedimentary successions indicate that anoxia was much restricted. The shift to m
