Figure 4 Measured sections of the Huns-Spitskopf members representative of the different paleogeographic zones. Sections show correlations of large-scale sequences A-E, medium-scale sequences 1-18, and distribution of small-scale sequence types. See Figure 1 for locations.

...) ( Germs, 1974 , 1983 and Geyer, 2005 ). This is in agreement with the available radiometric ages ( Grötzinger et al. , 1995 ): A volcanic ash bed of the upper Kuibis Subgroup yielded a U/Pb single zircon age of 548 ± 1 Ma, a volcanic ash bed of the Spitskopf Member of the upper Schwarzrand Subgroup...

... ages, especially the upper Ediacaran successions, are poorly constrained. SIMS zircon U–Pb dating results in this study suggest that ash beds at the basal and middle parts of the Jiucheng Member (middle Dengying Formation) in eastern Yunnan Province were deposited at 553.6 ± 2.7/(3.8) Ma and 546.3...

... reveal a large negative δ 13 C excursion (−7.2‰, L1′) in the Daibu Member, which matches the previously published data for the Laolin section, and a large positive excursion (+3.5‰, L4) in the Dahai Member, which was not shown in the published data. The excursion L1′ correlates well with the similarly...

... coincident with the SB at the base of the Nomtsas Formation (Grotzinger et al . 1995 ). However, recent recalibration of radiometric dating may indicate that the E-C boundary is placed within the upper part of the Spitskopf Member (Schmitz, 2012 ; for ongoing work on the geochronology of these strata, see...

After the termination of reef growth, the reefs were enveloped by shales of the Feldschuhhorn and Spitskopf members (Fig. 1 b). The affinity, mineralogy and reproductive habits...
