From Rodinia to Pangea: Geodynamics, Life and Climate

Transcription

1 1 st 9 th November, 2018, South China Second Circular From Rodinia to Pangea: Geodynamics, Life and Climate

2 General Information South China is chosen for the 2018 IGCP Field Symposium because it holds the key information for understanding the evolution of the supercontinent Rodinia, the onset and termination of the Cryogenian Snowball Earth events, the birth of complex life in the Ediacaran Period, and the tectonic affinity change of the South China Block from Rodinia to Pangea. These geological records are relatively well preserved and exposed in the Three Gorges Region, between Yichang and Shennongjia, northwestern Hubei Province in South China (Fig.1). The Symposium includes two days of indoor meeting and six days of field trip. Provisional Programme November 1 st, 2018, Arrival and Reception November 2 nd 3 rd, 2018, Oral and Poster Presentation (Indoor meeting in Yichang City) November 4 th 9 th, 2018, Field Trip around Yichang Shennongjia Region The symposium will be officially closed at 8:00 pm, November 9 th, November 10 th, 2018, Departure.

3 During the field trip, we will visit the following geological sites (Fig.1): (1) the Kongling Complex, consisting of the Archean and Paleoproterozoic metamorphic rocks which are considered as the oldest basement of the Yangtze craton (Fig.2A); (2) the Shennongjia Group, ~1.2 Ga silisiclastic and carbonate strata (Fig.2B); (3) the newly recognized Miaowan Ophiolite complex (Fig.2C) dated at ~1.1 Ga, which might be related to the Grenville-aged orogeny and thus to the assembly of Rodinia; (4) the ~820 Ma Huangling Granitoids and the Xiaofeng composite dykes (Fig.2D) which are under intensive debate as to whether they were related to a high-paleolatitudinal superplume or to a peri-rodinia subduction zone; (5) the Liantuo and Nantuo formations, presenting the pre-cryogenian siliciclastic deposits and glacial diamictites, respectively (Fig.2E); (6) the Ediacaran Paleozoic carbonate-shale sequence (Fig.2F) that preserves the oldest multicellular animal fossils and many other well-studied fossil assemblages.

It has an over two-thousand-year long history and four million multiple ethnic citizens, countless spectacular sites of mountain and water and variedly savory foods. Three Gorges Dam (Fig.3A), the world's largest power station in terms of installed capacity, is located ~40 km west of the city. The Shennongjia National Nature Reserve, listed as World Heritage Site since 2016, is located ~200 km west of Yichang. Besides the Meso-Neoproterozoic geological records we will visit, the Shennongjia region boasts very high plant diversity protected animal species and the mystery of Wildman.

5 Scientific Themes The two-day indoor meeting (including 5 scientific themes) will be held for delegates to present their latest achievements, during mutual study and communications to promote scientific understanding and cooperation. Theme 1: Progress on Supercontinent Reconstruction: New Findings and Developing Approaches Theme 2: Supercontinent Cycle and Geodynamics Theme 3: Chinese Cratons and Orogenic Belts in Supercontinents Theme 4: Life and Environment Coevolution: from Nuna, Rodinia to Pangea Theme 5: Climate Changes during Critical Transitions of Earth History: Observations, Interpretations and Modeling Registration Fees and Payment Registration is secured via payment of the appropriate registration fee. The registration fee for the indoor meeting covers conference welcome dinner (November 1 st, 2018), coffee/tea breaks, daily meals, abstract volume, and venue cost. The registration fee for the field trip covers the field guide, hotels, daily meals and transportations.
