“…Similar facies have been observed in deep lakes as the result of turbidity underflows triggered by gravity instability or sediment-laden fluvial discharge entering lower-density water (Ludlam 1974;Lambert and Hsü 1979;Mingram 1998;Freytet and Verrecchia 2002;Corella et al 2011aCorella et al , 2011b. However, graded-laminated limestones have also been described in playa lakes and shallow saline lakes (Eugster and Hardie 1975;Hardie et al 1978;Smoot 1983;Paik and Kim 2006) and continental wetlands (Buscalioni and Fregenal-Martínez 2010), as the result of sedimentcharged water currents followed by deposition of mudstone when calm conditions are recovered. In shallow water bodies, sediment resuspension is a common process that produces graded laminae, in that it includes erosion of fine-grained sediments from the bottom (top uncompacted material is easily resuspended), distribution of this material by currents, and settling when calm conditions are recovered (Bengtsson and Hellströ m 1992;Jin and Sun 2007).…”

The Lower Cretaceous (Berriasian) Valdeprado Formation (Cameros Basin, northern Spain) contains more than 900 m of laminated carbonates and pseudomorphs after sulfates. Traditionally, many sedimentary packages of different ages and lithologies have been interpreted as deep-water deposits based essentially on the abundance of laminations and the absence of subaerial exposure features. In contrast, the Valdeprado Formation provides an example of a shallow-water deposit dominated by laminations with scarce evidence of subaerial exposure, and gives criteria to solve the challenge of distinguishing shallow-water and deep-water, ancient laminated deposits.The two most abundant facies all along the Valdeprado Formation are: a) parallel-laminated limestone, formed by alternating carbonate mudstone and calcite and quartz pseudomorphs after displacive gypsum, and b) graded-laminated limestone, consisting of quartz, mica, ostracodes, and pseudomorphs after detrital gypsum grains at the base, which changes gradually upwards to carbonate mudstone. Parallel-laminated limestone and graded-laminated limestone could have been deposited in either deep or shallow environments as a result of salinity fluctuations driven by alternation of flooding and evaporation and by sediment resuspension processes, respectively. Subaerial exposure features, such as desiccation mudcracks, are scarce in most of the succession, except in a few meter-scale stratigraphic intervals where they are very abundant. Interestingly, in these intervals desiccation cracks are present at the tops of several successive laminae (up to 25 mudcracked laminae per meter of deposit), indicating that, at least during those periods of time, deposition occurred in shallow water bodies that were desiccated frequently. In the upper part of the stratigraphic section, parallel-laminated and graded-laminated limestones are associated with current-ripple and wave-ripple cross-laminated arenites, and ostracode mudstone to wackestone with centimeter-size pseudomorphs after lenticular gypsum, and abundant desiccation mudcracks and tepees, which also suggest sedimentation in shallow-water environments. Moreover, the laminated carbonates display continuous, parallel layering, and the same facies along the 40-km-long outcropping area. These deposits are directly interbedded with, and pass laterally to, siliciclastic sandy-muddy flat deposits in the western area of the basin, without clinoforms, slump structures, or slide masses in between. All of these features suggest deposition in shallow, perennial carbonate-sulfate water bodies and their peripheral mudflats, developed in a flat-bottomed basin with no marked gradients.

The Gusandong Tuff (Kusandong Tuff), known as a very significant key bed in the Cretaceous Gyeongsang Basin, is divided into (1) Northern Gusandong Tuff (NKT), (2) Southern Gusandong Tuff (SKT), and (3) Sinsudo Tuff, which were derived from different vents. In order to suggest their more accurate eruption times and to contribute to establishing stratigraphy of the basin, SHRIMP U-Pb zircon ages were determined from the three tuffs. As a result, the virtually same ages of 103.0±1.2 Ma and 104.1±1.3 Ma were obtained from NKT and SKT, respectively, which mean that they simultaneously erupted during 103~104 Ma. The zircon ages obtained from the Sinsudo Tuff are however divided into two groups i.e. 103.4±2.1 and 95.79±0.98 Ma. Based on distinctive morphology and cathodoluminescence image of the younger zircons, the younger age, 95.79±0.98 Ma, is much more reasonable as the eruption time of the Sinsudo Tuff.

“…However, the lake level fluctuations are from a shallow lake, with wave ripple (Sw) and distal distributary channel deposits (Lsh), to more deep lake as attest the presence of mouth bar deposits (until 10 m in thickness). The lake wasn't so shallow because no dessication or pedogenetic features are observed within F facies attributed to offshore lake deposits, as in fluvial floodplain and playa lake (Rogers and Astin, 1991;Paik and Kim, 2006). These depositional environments occur in the middle and upper part of the outcrops (Figs.…”
