Chapter 32 Neoproterozoic glacial records in the Yangtze Region, China

Abstract: The Nanhua rift occurred at c. 820 Ma. The last rifting stage was likely associated with the Neoproterozoic glaciations. The glacially influenced sequence, in ascending order, comprises the Jiangkou Group (c. 720-663 Ma), the interglacial Datangpo Formation (Fm.) (c. 663 Ma) and the Nantuo Fm. (,. In deep-water environments the glacially influenced units exhibit conformable contacts with a transitional lower boundary and a sharp upper boundary. In shallow marine environments, the lower boundary is always uncon… Show more

“…The iron formation is stratigraphically restricted to the lower Fulu Formation, which occurs above diamictites of the Chang'an within the glaciogenic Jiangkou Group (Zhang et al, 2011). The Jiangkou Group is the lower of two glaciogenic intervals in South China.…”

“…The Fulu iron formation occurs between massive diamictites of the upper Chang'an Formation and arkosic arenite and greywacke with lonestones of the Liangjiehe Member of the Fulu Formation (Zhang et al, 2011). The Fulu IF has not been well described, but was evidently deposited in an evolving rift basin in intimate association with mafic volcanics, which comprise the main clast type within the IF (Tang et al, 1987).…”

“…The Jiangkou glacigenic units are widely distributed in the Hunan-GuizhouGuangxi adjacent areas, and are composed of the Chang'an and Fulu formations. The Chang'an Formation is characterized by a suit of overall diamictite successions underlain by the sericite slate of the Gongdong Formation with a gradual transitional contact, both of them deposited in deep-water environments (Zhang et al, 2008(Zhang et al, , 2011. The Fulu Formation is composed of the Liangjiehe Member and Gucheng Member dominated by well-bedded sandstones with banded iron formations (BIF) at its base.…”

“…As negative δ 13 C excursions occurred before each of the snowball Earth glaciations, CO 2 drawdown associated with perturbations of the global carbon cycle was considered to be the cause of the first low-latitude glaciation (Tziperman et al, 2011;Schrag et al, 2002). In South China, two glaciations, recorded by Jiangkou Formation and Nantuo Formation, respectively, have been documented (Zhang et al, 2011). The new U-Pb age dating indicates that the older glaciation (Jiangkou glaciation) in South China was initiated at 716 Ma (Lan et al, 2014), implying a synchronous and global Sturtian glaciation.…”
