报告题目:揭示蕨类植物韧皮部的多样性和进化报告人:傅子珊报告人单位:University of Edinburgh, United Kingdom报告时间:9月19日(周四)下午 14:30-16:00报告地点:图书馆三楼报告厅报告简介:韧皮部(Phloem)是维管植物运输光合产物和信号传递的基本组织,对维管植物至关重要。然而,因为韧皮部细胞壁薄,组织脆弱,在化石中通常保存较差,以致我们对韧皮部进化过程理解甚少。通过整合现存和已灭绝蕨类植物的组织学证据,我们量化了蕨类植物关键韧皮部特征在地质时间尺度上的进化,为进一步揭示陆地植物韧皮部的进化提供依据。主办:重点实验室、青促会、科技处、人教处

特别研究助理期满工作报告(8月16日)
报告题目:Late Cambrian-Ordovician faunas from Iran and South China: Similarities and differences报告人:Hadi Jahangir报告人单位:中国科学院南京地质古生物研究所报告时间:8月16日(周五)上午10:00报告地点:图书馆三楼学术报告厅主办:古生物学与油气地层应用重点实验室、人事教育处报告简介:Late Cambrian‒Ordovician stratigraphy and faunas from various sections across different geological zones in Iran and Guizhou Province, South China, were analysed to explore potential biogeographical and palaeogeographical relationships based on faunal evidence, stratigraphy, and geological events during this interval. The possible absence of several conodont biozones at the Cambrian‒Ordovician transition in the biostratigraphical succession of the Yangtze Platform may indicate a hiatus near the system boundary. A similar hiatus has been documented in Alborz tectonic unit of northern Iran.A notable exception is the Cambrian‒Ordovician transition documented from slope deposits on the Saluk Mountains (Kopet-Dagh domain of Alborztectonic unit), which shows continuous biostratigraphical succession comparable to the Jiangnan Slope of South China. To date, this is the only complete conodont biozonal succession documented from Iran. It is subdivided into 11 succeeding conodont biozones, ranging from the Proconodontusmuelleri to Paltodusdeltifer zones. Two graptolite-bearing horizons with early representative of Rhabdinoporahave been documented from the CordyloduslindstromiZone, close to the inferred position of the Cambrian–Ordovician boundary. Additionally, Iapetognathus conodont elements were recovered from several stratigraphical levels within the CordyloduslindstromiandCordylodus angulatuszones. The presence of early Rhabdinoporaand Iapetognathusconodonts in the lower CordyloduslindstromiZone of southern Kopet-Dagh is of outstanding importance for high resolution correlation of the Cambrian–Ordovician boundary interval and for more precise definition of the system boundary.Overall, recent progress in studies of Ordovician‒Silurian stratigraphy and faunas of Iran, particularly in the Alborz tectonic unitand the East-Central Iranian Platform, has led to a more accurate definition of stage and system boundaries, as well as a characterisation of the Great Ordovician Biodiversification Event (GOBE) in Iranian sections. It also reveals a distinct similarity between the biostratigraphy and faunas of South China and Iranian terranes.报告人简介:Hadi Jahangir博士毕业于马什哈德费尔多西大学(Ferdowsi university of Mashhad),为伊朗古生物协会会员,2021年8月至今于中国科学院南京地质古生物研究所从事特别研究助理工作。目前在《Journal of Asian Earth Sciences》、《Bulletin of Geosciences》等期刊发表多篇学术论文。

报告题目:Reef communities and carbon isotope excursions of the Lower Ordovician reveal early escalation of the Great Ordovician Biodiversication Event (GOBE)报告人:Jongsun Hong, Associate Professor报告人单位:Kangwon National University报告时间:7月22日(周一)下午3:30-4:30报告地点:图书馆三楼报告厅主办:重点实验室、科技处、人教处报告简介:Middle Tremadocian to earliest Floian isotopic carbon excursions are reported from the Lower Ordovician Dumugol Formation in eastern Sino-Korean Platform. These excursions are well-correlated with coeval strata elsewhere. This finding reaffirms that the Top Skullockian Isotopic Carbon Excursion (TSICE) may be correlated globally. It also suggests that the Late Stairsian Isotopic Carbon Excursion (LSICE) would also be useful for inter-regional correlation. First microbial-lithistid Archaeoscyphia reefs in the formation developed in a low-energy deeper subtidal deposits, occurring between the TSICE and LSICE. It represents the habitat expansion of the reef community that invaded into deeper subtidal. A similar phenomenon and emergence of new sessile organisms in shallow subtidal happened in a stratigraphic interval between the two excursions in Laurentia (now Utah, USA) and South China, respectively. These happened in a short span of time within a million year. Such abrupt increases in ecological and taxonomic diversities signify a pulse of the early GOBE, shortly after a possible anoxic event marked by the Top Skullrockian Isotopic Carbon Excursion (TSICE). 报告人简介:Jongsun Hong副教授于2015年从高丽大学获得博士学位,随后在高丽大学担任Research professor,2017年在Korea Polar Research Institute从事博士后研究,2017年9月进入Kangwon National University工作。在《Journal of the Geological Society of Korea》,《Palaeogeography, Paleoclimatology, Palaeoecology》,《Sedimentary Geology》等期刊发表多篇学术论文。

报告题目:Tectonic and paleoenvironmental evolution of deep-time Antarctica: from sedimentary records of northern Victoria Land报告人:Jusun Woo, Assistant Professor报告人单位:Seoul National University报告时间:7月22日(周一)下午2:30-3:30报告地点:图书馆三楼报告厅主办:重点实验室、科技处、人教处报告简介:Sedimentary strata in northern Victoria Land (nVL), Antarctica contain evidences of Antarctica’s deep-time environments ranging from Cambrian to Jurassic in geological age. The lower Paleozoic Bowers Supergroup consists of low-grade metasedimentary rocks including siliciclastics, carbonates, and volcanics. The basal part of the supergroup is characterized by volcanic rocks and deep-marine turbidites and the overlying sedimentary facies successions suggest a major regression from continental slope, shallow marine to fluvial environments. Rare carbonate rocks occur as olistoliths in the deep-water sediments and preserve microbial reef textures which provide hints to understand unpreserved Cambrian carbonate platforms in the Antarctica. These sediments were deposited in the basin evolved along with the early Paleozoic tectonic processes of the Ross Orogeny. The overlying, late Paleozoic to Jurassic Beacon Supergroup is characterized by thick succession of sandstones and conglomerates with fluvial origin. The basal part of the supergroup is characterized by diamictites formed in glacio-lacustrine-fluvial environments which prevailed in southern part of the Gondwana Land in the late Paleozoic. The upper part of the supergroup contains volcaniclastics and is eventually overlain by Jurassic Ferrar Group. The Ferrar Group in nVL consists of effusive and eruptive tholeiitic volcanics which formed thick succession of lava flow units with thin volcaniclastic interbeds and dyke-and-sill systems. These volcanics are formed mostly by continental flood basalt related to the rifting in the early stage of the breakup of the Gondwana.The sedimentary rocks of nVL record succession of geological events in the Antarctica such as formation of Antarctic continent in the early Paleozoic time and break-up of Gondwana Land in the Jurassic. The rocks also provide new data set for integrate understanding of past global environmental events such as Cambrian microbial reef evolution and development of late Paleozoic ice age. There is still a lot more interesting geology to come in the Antarctica.报告人简介:Jusun Woo助理教授于2009年从首尔大学获得博士学位,随后在Korea Polar Research Institute 担任Senior Research Scientist,从2019年至今在首尔大学担任助理教授职位。研究兴趣主要包括华北、黄海、格陵兰岛和南极洲内相关沉积盆地的地层学和沉积学工作。
