“…The middle part changes into shallow lake deposits from meandering river deposits. The upper part is also meandering river deposits (G. D. Wang et al, 2015; Yoshino et al, 2017). The Mingshui Formation is 232 m thick and divided into member 1 (280–116 m) and 2 (116–48 m).…”

“…15 depositional facies are identified in the Mingshui Formation (Cheng et al, 2009; G. D. Wang et al, 2015). Both the member 1 and 2 of this Formation are composed of the meandering river and shallow lake facies (Yoshino et al, 2017). In general, the depositional environment of the Mingshui Formation is a meandering river, accompanied by lake fluctuations.…”

“…J. Li et al (2011) reported 8 palynological assemblages from SK1 core (A drilling project was carried out at the Daqing Oilfield), and established high‐resolution palynological biostratigraphy, providing data for the geologists to revise Late Cretaceous paleoenvironmental reconstructions. Yoshino et al (2017) discussed the palynological record from the Sifangtai and Mingshui Formations of the SK1 core. Unfortunately, the palynomorph counts and the discussion on paleoclimatic changes were limited.…”

“…Several previous studies related to palynological biostratigraphy and paleoclimate have been conducted on Cretaceous sediments of the Songliao Basin (Gao, 1988; Gao et al, 1999; Huang et al, 1999; Ji, Zhang, & Song, 2015; J. Li, Batten, & Zhang, 2011; Xi et al, 2011; Yoshino, Wan, Xi, Li, & Matsuoka, 2017; Zhao et al, 2014). For example, Gao et al (1999) identified 18 palynological assemblages from the Huoshiling–Mingshui Formations obtained from more than 500 wells in the Songliao Basin and proposed a humid to semi‐humid subtropical climate during the whole Cretaceous.…”

To better understand the vegetation and possible paleoclimate change, we recovered a palynological record obtained from the ZKD14 core covering from the Sifangtai and Mingshui Formations in the northern Songliao Basin, northeastern China. Based on the abundance and variations in determined palynomorphs, two palynological assemblages can be distinguished, including Schizaeoisporites-bisaccate-Tricolporopollenites and Taxodiaceaepollenites-bisaccate-Tricolporopollenites. These palynological assemblages are assigned to the late Campanian-Maastrichtian stage based on the geological range of some important elements and the correlation with relevant assemblages of other areas. In this paper, we applied a sporopollen-climate transforming methodology, which uses the percentage of xerophytic and thermophilic taxa to indicate stratigraphic trends of humidity and temperature, respectively. Then two vegetation and paleoclimate phases were reconstructed based on the ecological habits of the parent plant, as well as the abundance variation in xerophytic and thermophilic taxa: (i) The vegetation type was interpreted to reflect a mixed conifer forest with varying pteridophytes landscape, presenting a hot and arid subtropic climate during the Sifangtai to lower part of member 2 of the Mingshui Formations. (ii) The vegetation type was characterized by a conifer-dominant landscape. Accordingly, the climate turned more humid and colder during the upper part of member 2 of the Mingshui Formation. The global cooling event (Campanian-Maastrichtian Boundary Event: CMBE) which occurred between 72.0-70.0 Ma appears to have an important influence on the climatic condition of Songliao Basin.

“…Additional foraminifera (Xi et al, 2011) and palynomorph records (Li et al, 2011) suggest a late Coniacian–Santonian age for Member 1. Wu et al (2014) constrained the age of the Sifangtai Formation between 76.077 and 72.86 Ma (middle–late Campanian) on the basis of magneto-, cyclo-, and biostratigraphy; additional palynomorph data suggest a late Campanian age (Yoshinoda et al, 2017). Furthermore, there is a correlation between the ostracode faunas of the Sifangtai and Minhe, Qingyuangang, and Jiaozhou formations, which have been previously assigned to the Campanian–Maastrichtian (Liu et al, 2004; Xi et al, 2019; Wang et al, 2019).…”

Despite the abundant literature on limnic Cretaceous ostracode faunas, the database on mid-Late Cretaceous taxa is still scarce. The Songliao Basin in northeastern China preserves a diverse assemblage of ostracode fossils from the Santonian–Campanian Nenjiang and Sifangtai formations. This rather unique material is of major importance to comprehend Early to mid-Late Cretaceous (Cenomanian–Campanian) limnic ostracode faunas and therefore the evolution of Late Cretaceous basins in China. A study of this fauna was conducted to detail the taxonomy of ostracode species from members 1 and 2 of the Nenjiang and Sifangtai formations in the Songliao Basin. Well-preserved specimens of 14 ostracode species were recovered from samples of the ZKY2-1 well in southwestern Songliao Basin: Scabriculocypris liaukhenensis Liu in Netchaeva et al., 1959, Ilyocyprimorpha netchaevae Su in Netchaeva et al., 1959, Cypridea acclinia Netchaeva in Netchaeva et al., 1959, Cypridea cavernosa Galeeva, 1955, Cypridea gracile Netchaeva in Netchaeva et al., 1959, Cypridea lepida Ye in DOFEAD, 1976, Cypridea squalida Sou in Netchaeva et al., 1959, Fabaeformiscandona? Disjuncta (Hao in Hao et al., 1974), Lycopterocypris profunda Lübimova, 1956, Mongolocypris magna (Hou, 1958), Mongolocypris tera (Su in Netchaeva et al., 1959), Talicypridea obliquecostae (Szczechura and Błaszyk, 1970), Talicypridea reticulata (Szczechura, 1978) and Renicypris renalata (Su in Hao et al., 1974). Four of the species identified received emended descriptions and diagnoses. Other important results include the first discussion on sexual dimorphism in Cypridea acclinia and Fabaeformiscandona? disjuncta, the first study on the ontogeny of Ilyocyprimorpha netchaevae, and the reassignment of Cypridea liaukhenensis to the genus Scabriculocypris. Several species recorded herein are also found in other continental far-eastern Asian basins, while genera range from worldwide to far-eastern Asian distribution; these results support strong affinities among faunas of Mongolia, China, and Japan.

Late Cretaceous stratigraphic division in the northwestern Songliao Basin, Northeast China: Evidence from palaeontology and palaeomagnetism

This paper combines new palaeomagnetic studies, palaeontological dating, and sedimentary analyses to propose a modified stratigraphic classification scheme in the northwestern Songliao Basin, which is of great significance for stratigraphic correlation, sedimentation analysis, basinal subsidence, and oil and gas exploration. New palaeontological and palaeomagnetic evidence redefined a group of semi‐consolidated lacustrine strata, buried beneath the Quaternary Yaluhe Formation on the Western Slope of the Songliao Basin, as Late Cretaceous, not the Middle Pleistocene. The chronostratigraphic framework re‐evaluates its stratigraphic age as late Coniacian to early Campanian (Late Cretaceous), between 83 and 85 Ma. Sedimentation research from 17 boreholes on the Western Slope of the Songliao Basin displays that the semi‐consolidated strata successively experienced lacustrine and delta facies deposits. Comparison of this new stratigraphy with the Late Cretaceous sequences on the adjacent Central Depression of the Songliao Basin reveals significant variations in lithology and palynological assemblages. Three new palynological assemblages are also reported from the Late Cretaceous sequences of the Songliao Basin.
