| 1 | 华南五峰组-龙马溪组黑色岩系时空展布的主控因素及其启示显示文摘在回顾五峰组-龙马溪组两个地层单位沿革并重申其定义与划分基础上,重建了华南五峰组-龙马溪组及其相关地层序列的区域地层框架.根据这一框架中奥陶-志留纪黑色笔石岩系的穿时性、以及相关地层序列纵向演化特征与岩石圈板块挠曲模式的联系,结合所发现钾质斑脱岩源岩的板块汇聚背景,以及该阶段海平面升降与黑色岩系对应关系,提出控制该阶段华南黑色岩系的时空展布格局的主要因素有两个,即该阶段自南东向北西的华夏地块与扬子地块幕式汇聚过程所产生的岩石圈板块挠曲-周缘前陆盆地的同向迁移,以及该阶段两次全球性的三级海平面变化快速上升阶段所导致的缺氧及欠补偿水体.本文认为,要在华南奥陶-志留纪(包括其他断代)寻找其他可能的烃源岩层位,可能要首先考虑类似背景下这两种因素综合作用所导致的快速沉降及深水缺氧的沉积环境. | 苏文博 李志明 Frank R.Ettensohn Markes E.Johnson Warren D.Huff 王巍 马超 李录 张磊 赵慧静 | 2007 | 地球科学(中国地质大学学报)2007，32，6： | 109 |
| 2 | Timing the termination of the Doushantuo negative carbon isotope excursion: evidence from U-Pb ages from the Dengying and Liuchapo formations,South China显示文摘The Doushantuo negative carbon isotope excursion(DOUNCE) is the largest known marine inorganic carbon isotope anomaly. The origin of this pronounced negative excursion is still an enigmatic issue that attracts geologists. Time constraints on the excursion are the critical information that would provide insight into its genesis. In previous decades, the timing of its termination has been constrained by the widely cited zircon U-Pb age of 550.5 ± 0.8 Ma for the tuff at the top of the Miaohe Member at the Jiuqunao section in the Yangtze Gorges area, South China. However, results of recent studies indicate that the reliability of this time constraint needs to be re-evaluated. Here, a geochronological study was carried out using two K-bentonites from Fanglong in South China. A K-bentonite in the lower Dengying Formation yielded a U-Pb age of 557 ± 3 Ma, while a K-bentonite in the basal Liuchapo Formation yielded an age of 550 ± 3 Ma. Based on regional correlations between the Ediacaran successions in South China,the age(557 ± 3 Ma) for the K-bentonite in the lower Dengying Formation may serve as a second critical timing constraint for the ending of the DOUNCE. Combined with available estimates of the DOUNCE duration, our new data indicate that the DOUNCE has a maximum onset age ~570 Ma. | Mingzhong Zhou Taiyi Luo Warren D.Huff Zhiqing Yang Guanghong Zhou Tian Gan Hua Yang Di Zhang | 2018 | Science Bulletin2018，63，21： | 6 |
