| 英文摘要 | The delta(13)C values of Lower Cretaceous Aptian-Albian platform-type carbonates in the Cuoqin Basin, North Tibet vary between 2.48parts per thousand and 5.46parts per thousand. The mean value is 3.93parts per thousand. The values are not only provided with positive excursion, but also 1.17parts per thousand higher than those of contemporaneous pelagic carbonates which possess pretty high delta(13)C values. The origin is approached. During the oceanic anoxic events, a great number of organisms were rapidly buried, causing the increase of the delta(13)C value of oceanic total dissolved carbon (TDC) and generally promoting the values of marine carbonates. After that, owing to the organisms undergoing different isotopic fractionation in the paleo-ocean with stratified structure, delta(13)C values of shallow sea carbonate were obviously higher than those of pelagic carbonates. |
