“…In recent years, however, hypotheses on the genesis of the sedimentary strata in Lingshan Island have varied between scholars. Some researchers maintain that it was a marine sedimentary environment (Lü et al, 2011;Zhang et al, 2013;Wang et al, 2014Wang et al, , 2016Zhou et al, 2015;Yang et al, 2017;Zhang et al, 2017;Zhou et al, 2017), while others believe that it was a continental depositional environment (Zhong, 2012;Shao et al, 2014;Ge and Zhong, 2017;Li et al, 2017;Meng et al, 2018a;Meng and Li, 2019a). Lü et al (2011) proposed that the flysch with welldeveloped soft-sediment deformation structures was formed in a marine sedimentary environment.…”

The sedimentary background and sedimentary environment of the Lower Cretaceous of Lingshan Island, Shandong, remain unclear. There is considerable controversy as to whether the sedimentary environment was marine or continental. In this study, analyses were conducted with respect to indicators of paleosalinity, the chemical composition of clay, paleobiota, the characteristics of strata exhibiting salinization in eastern China during the Early Cretaceous, and the relationship between paleosalinity and paleoclimate. The results indicate that the sedimentary environment of the Lower Cretaceous Laiyang Group of Lingshan Island was that of a salified lake rather than a marine environment. This study not only provides a reference for determining the sedimentary environment of the Lower Cretaceous Laiyang Group of Lingshan Island but also offers a new perspective for the study of Cretaceous strata with salinization characteristics in eastern China.

“…For the reason of comparison between strata in Lingshan Island and Jiaolai Basin, the sedimentary units below the white rhyolite layer were allocated to Laiyang Group, and units formed after the rhyolite layer are assigned to Qingshan Group (Yang & van Loon, ). However, the latest fieldworks have identified an unconformity interface which separates the Laiyang Group and Qingshan Group (Zhou et al, ). Considering the sedimentary rock association and depositional environment, five units were identified for the exposed Lingshan Island strata (Figure ).…”

North China Craton experienced significant lithospheric destruction or delamination during the Late Mesozoic, accompanied with the emergence of numerous basins and intensive volcanism. Extensional basins also formed in East Shandong Province.Even though they have been studied for decades, the relationship between basin development and tectonic processes still remains obscure. Recently, a set of Early Cretaceous strata has been found in Lingshan Island. It is characterized by translating from turbidite deposits to terrestrial strata units and ending up with a unique volcaniclastic layer within a relatively short time span. Previous studies have reached an agreement that Lingshan Island strata are formed in a distinct sedimentary background compared with the coeval sedimentary units in Jiaolai Basin. Essential information about basin development and its tectonic setting in this region during Early Cretaceous are preserved in Lingshan Island strata. In this study, it shows the characteristics of heavy mineral assemblage and the characteristics of detrital minerals' chemical component in the two representative samples. Based on these studies, itindicates that Lingshan Island Basin was developed in a transpressional tectonic setting with complex source materials, mainly from Qianliyan Uplift during the period ca. 123-120 Ma. Then, the basin evolved within an extensional setting and was filled with locally derived clastics during 120 to 105 Ma. In addition, the basin evolved during the process of progressive lithospheric thinning and asthenosphere upwelling.

“…The mechanism, which initiates the formation of sand dykes here, may be associated with seismic shocks (Mills, 1983;Audemard and De Santis, 1991;Obermeier et al, 1993;Obermeier, 1996;Rodríguez-Pascua et al, 2000) and/or tremors caused by the volcanic activities. The tremors, which are related to volcanic activities and frequently control the basin, should have initiated the liquefaction and fl uidization event (Samaila et al, 2006;Tian et al, 2014;Zhou et al, 2017).…”

In the Western Anatolian region, NE-SW, E-W directional basins were developed which were limited to the extension-related faults beginning in the late Oligocene to early Miocene. The fi llings of these basins consist of fl uvial-lacustrine deposits containing volcanic and volcaniclastic intercalations. These deposits include intensive local unconformities and soft sediment deformation structures. The fi lling of the Bigadiç Neogene Basin which is one of these basins, constitute base limestone unit, lower tuff unit, lower borate unit, upper tuff unit and upper borate unit. The base limestone unit composed of claystone, marl, limestone, dolomitic limestone facies was deposited in the deep lacustrine environment. The soft sediment deformation structures were defi ned in the base limestone unit, which outcroped in the south of Bigadiç. These are: slumps, rock falls, chaotic structures, clastic dykes, synsedimentary faults and breccia limestone. Deformation mechanisms are related essentially to the increase of slopes of layers, liquidization and fl uidization. In the study area; regional tectonics, sedimentological data, and deformation structures are evaluated together, it is concluded that these structures are formed by tectonic and seismic (earthquakes related to tectonic origin and syndepositional magmatic activities).
