| Abstract | The end-Ordovician (Hirnantian) glaciation, causally linked with the first of five Phanerozoic mass extinction events, is the first major Phanerozoic-glaciation with short duration and paradoxically happened under a relative greenhouse-condition. Here, we present the first zinc isotope study on both carbonate and shale successions that span the Ordovician-Silurian boundary interval in South China. Two positive shifts in Zn isotope composition are observed during two main periods of glacial maxima, indicative of two pulses of extensive carbon burial. The enhanced organic carbon burial during glacial maxima intervals might be causatively linked to cooling- induced elevation in organic carbon burial efficiency. This implies that a large oceanic organic carbon reservoir played a vital role in regulating the atmospheric pCO(2), causing the Hirnantian glaciation and producing the pattern of glacial-to-deglacial change, sensitive to the temperature effect. |
