| 英文摘要 | Climate warming, probably as a result of massive degassing of greenhouse gases from the Siberian Traps magmatism, has often been acclaimed as a major cause of the end-Permian mass extinction. Indeed, several studies have documented a sudden rise in seawater temperatures during the latest Permian-earliest Triassic, as evidenced by oxygen isotopic records measured on conodont apatite. However, whether such a rapid increase in seawater temperatures occurred before, during, or after the mass extinction remains controversial. Moreover, the pattern of this rise in seawater temperatures and its timing relative to the latest Permian-earliest Triassic carbon cycle disruption, mass extinction, as well as the Siberian Traps magmatism still need to be rigorously examined in various regions. In this study, we present high-resolution oxygen isotopic records of conodont apatite (delta O-18(apatite)) from the Upper Permian-lowermost Triassic interval at the Abadeh section, central Iran that are analyzed with in situ secondary ion mass spectrometry (SIMS) method. The delta O-18(apatite) results from Abadeh demonstrate a clear pattern consisting of three phases: (1) From the lower Wuchiapingian Clarkina dukouensis Zone to the end-Permian mass extinction horizon, delta O-18(apatite) values are relatively stable, fluctuating in the range of 18.28-20.15 parts per thousand with an average of 19.44%. (2) delta O-18(apatite) value remains high as 19.26 parts per thousand at the mass extinction horizon. Above this horizon, a sudden decrease occurs in the Clarkina hauschkei Zone and reaches a low value of 17.05 parts per thousand close to the Permian-Triassic boundary. (3) In the lowermost Triassic, delta O-18(apatite) values maintain a low baseline in the range of 16.92-17.39 parts per thousand with an average of 17.11 parts per thousand. Overall, the most dramatic change in delta O-18(apatite) values (i.e., a decrease of similar to 2%), converting into an abrupt warming of similar to 10 degrees C, occurred above the mass extinction horizon and below the Permian-Triassic boundary at Abadeh. The Abadeh delta O-18(apatite) record is consistent with previous results documented in South China, Iran, and Armenia in terms of the timing and magnitude of a substantial warming, and therefore represents a global signature. If applying the high-precision temporal framework established in the well-dated Meishan GSSP section to Abadeh, the abrupt warming of similar to 10 degrees C took only a maximum duration of similar to 37 kyr (thousand years). By projecting the carbon cycle change, temperature rise, mass extinction at the Abadeh and Meishan sections, and the temporal evolution of the Siberian Traps magmatism onto a unified timescale, the temporal correlation strongly suggests that the switch from dominantly extrusive eruptions to widespread sill intrusions is probably the most annihilating phase of the Siberian Traps magmatism, and is temporally consistent with the end-Permian mass extinction. |
