“…Changes in the overall percentages of carbonate and siliciclastic strata in such mixed lithofacies have been commonly linked to relative sea-level changes. In some ancient settings, such as the interface of a carbonate ramp and a deeper-water setting, rising sea level led to retreat of the carbonate belt and reduced input of carbonate sediment, and thus encroachment of a mud belt over the carbonate platform (Markello and Read, 1981;Calvet and Tucker, 1988;Chen et al, 2011Chen et al, , 2012. Myrow et al (2012) suggested that in inner detrital belt settings, the reverse may be the case, namely, that during lowstands, rejuvenated fl uvial systems may have increased mud input and stifl ed carbonate production, whereas during transgression, landward migration of shorelines may have led to alluviation, reduced sediment input, and increased carbonate production and deposition.…”

“…1; Meng et al, 1997;Feng et al, 2002). Much is known about the strata in the eastern part of the North China block with respect to sedimentary processes, paleontology, stratigraphy, and tectonic evolution (e.g., Kwon et al, 2006;Chough et al, 2010;Chen et al, 2011Chen et al, , 2012Lee and Chough, 2011;Chen andLee, 2013, 2014), but little is known of its western margin. There, a thick succession of strata was deposited in the Helan aulacogen, a tectonic feature that formed along this margin during the Mesoproterozoic, and then experienced uplift during the Neoproterozoic and renewed subsidence during the latest Neoproterozoic (Sun and Liu, 1983;Lin et al, 1991).…”

“…Early Paleozoic sedimentation in the Taebaeksan Basin (Choi & Chough, ; Kwon et al, ) and North China (J. Chen, Chough, Lee, & Han, ; Meng, Ge, & Tucker, ) took place near‐contemporaneously at ~ 520 Ma. To explore the early Paleozoic tectonic setting of the SKC, the geochronological information preserved within the lower Paleozoic Joseon Supergroup as well as the basement for deposition of the supergroup, i.e.…”

The Taebaeksan Basin is located in the mid‐eastern part of the southern Korean Peninsula and tectonically belonged to the Sino‐Korean Craton (SKC). It comprises largely the lower Paleozoic Joseon Supergroup and the upper Paleozoic Pyeongan Supergroup which are separated by a disconformity representing a 140 myr−long hiatus. This paper explores the early Paleozoic paleogeographical and tectonic evolution of the Taebaeksan Basin on the basis of updated stratigraphy, trilobite faunal assemblages, and detrital zircon U–Pb ages of the Joseon Supergroup. The Joseon Supergroup is a shallow marine siliciclastic‐carbonate succession ranging in age from the Cambrian Series 2 to Middle Ordovician. The Ongnyeobong Formation is the sole Upper Ordovician volcanic succession documented in the Taebaeksan Basin. It is suggested that in the early Paleozoic the Taebaeksan Basin was a part of an epeiric sea, the Joseon Sea, in east Gondwana. The Joseon Sea was the depositional site for lower Paleozoic successions of the SKC. Early Paleozoic sedimentation in the Joseon Sea commenced during the Cambrian Stage 3 (∼ 520 Ma) and ceased by the end of the Darriwilian (∼ 460 Ma). In the early Paleozoic, the SKC was located at the margin of east Gondwana and was separated from the South China Craton by an oceanic basin with incipient oceanic ridges, the Helan Trough. The spreading oceanic ridges and associated transform faults possibly promoted the uplift of the Joseon Sea, which resulted in cessation of sedimentation and break‐up of the SKC from core Gondwana by the end of the Ordovician.

“…This suggests that the central part of the platform was deeper than the periphery, which resulted in an intra‐platform basin (e.g., Markello & Read, ). The deposition of unit 3 ends with drowning of the platform, represented by abrupt facies change from microbialite‐ or oolite‐rich shallow facies to shaley deeper facies of the Gushan Formation (Chen, Chough, Lee, & Han, ).…”

Facies and platform development of a microbe‐dominated carbonate platform: The Zhangxia Formation (Drumian, Cambrian Series 3), Shandong Province, China

2018

Microbial carbonate has been increasingly recognized as an important player for sediment production and building up of organosedimentary deposits. The integrated spatio‐temporal pattern of microbial facies is important for understanding carbonate production processes in a carbonate platform. This paper focuses on the sedimentary facies and development of a microbe‐dominated platform in the Cambrian North China Platform (the Zhangxia Formation of the Cambrian Series 3) in Shandong Province, China. In the entire Zhangxia platform, deposition started with oolite‐dominated shoal‐lagoon system with rare microbialites. The shoal‐lagoon system in the western part of the study area kept up with sea‐level rise and formed a flat‐topped platform, whereas that in the eastern part failed to keep up and thus drowned. The platform top then changed to a microbe‐dominated carbonate platform consisting of thrombolite, stromatolite, dendrolite, and Epiphyton framestone. The initial significant microbialites were biohermal thrombolite and dendrolites, which subsequently changed into wider biostromal forms. The morphologic change was largely due to initial rapid rise in sea level and the following deceleration. Extensive biostromes of laterally coalesced thrombolite–Epiphyton bioherms occur in the shale‐dominated eastern part. These microbialites then perished by platform‐wide drowning. The vast initial development of microbialite facies of the Zhangxia Formation in the Shandong area was important for the establishment of an extensive microbialite‐dominated carbonate factory made by combination of an absence of reef‐building metazoans and possible transition of seawater chemistry from aragonite sea to calcite sea in the Cambrian Series 3. It is comparable to the other carbonate environments lacking dominant metazoan reef builders after the mass extinctions.
