“…Subsequent studies from the Lianjiang plain, the southeastern part of the Chaoshan plain, have confirmed these findings using ESR and OSL (Song et al, 2012;Tang et al, 2018). The combination of 14 C, OSL, and ESR dating, of the lower marine unit (M2) from the Lianjiang plain, shows that the results are also at MIS 5 rather than MIS 3 (Song et al, 2012;Tang et al, 2018). ESR ages of the basal terrestrial layer from the core WYZK-06 (at a depth of ca.100-130 m) in the Lianjiang plain fall approximately within MIS 7 (ca.…”

“…Accordingly, Zong et al (2015) demonstrated that the lower marine unit (M2) was deposited at a depth of around 45 to 80 m BSL; therefore, the actual age is likely to be older than MIS 5, rather than MIS 3. Subsequent studies from the Lianjiang plain, the southeastern part of the Chaoshan plain, have confirmed these findings using ESR and OSL (Song et al, 2012;Tang et al, 2018). The combination of 14 C, OSL, and ESR dating, of the lower marine unit (M2) from the Lianjiang plain, shows that the results are also at MIS 5 rather than MIS 3 (Song et al, 2012;Tang et al, 2018).…”

“…Some studies have demonstrated that the oldest Quaternary deposits (fluvial sediments, named the Nanshe Formation) do not exceed 55 ka BP, based on radiocarbon, thermoluminescence (TL) dating, and stratigraphic relationships (Chen, 1984a;Li et al, 1987;Zong, 1987;Li et al, 1988;Sun et al, 2007;Zhou, 2008). Nevertheless, results from other dating methods, including electron spin resonance (ESR) and OSL, have shown that the oldest Quaternary sediments in the Lianjiang plain, the southeastern part of the Chaoshan plain, date back to more than 260 ka (Song et al, 2012;Tang et al, 2018). Yet, our understanding of the formation and evolution of the Chaoshan plain delta is still debated, owing to different dating methods that require further evaluation.…”

Accurate chronology plays a crucial role in reconstructing delta evolution. Radiocarbon (14C) and optically stimulated luminescence (OSL) dating are widely used to establish a stratigraphic chronology of the late Quaternary sediments. The Chaoshan plain is located on the southern coast of China and borders the South China Sea. The thickness of Quaternary sediments in this area extends to a depth of 140 m and is considered a valuable archive for studying the evolution of the delta in response to climate and sea-level changes. However, reliable chronological data are still very limited. In this paper, eighteen accelerator mass spectrometry (AMS) 14C and thirteen quartz OSL ages were obtained from two cores from the Rongjiang plain, the middle part of the Chaoshan plain: ZK001 (90.85 m in depth) and ZK002 (100 m in depth). The present study aims to provide a reliable chronology of the Chaoshan plain based on OSL and 14C dating methods and examine the upper limit of the 14C dating on plant remains. Our results show that (1) OSL ages of cores ZK001 and ZK002 range from 56 to 1.7 ka and from 177 to 15 ka, respectively; (2) 14C ages of core ZK002 range from 8.8 to 41 cal ka BP, showing that all 14C ages below ca. 30 m depth are younger than OSL ages and that the upper limit of plant remains is around 35 cal ka BP. OSL ages are consistent with stratigraphic order within uncertainties. The oldest OSL age obtained from core ZK002 is 177 ± 20 ka at a depth of 93 m, and is considered a minimum age. This indicates that the Quaternary deposition in the Rongjiang plain can trace back to at least the marine isotope stage (MIS) 6 during sea-level lowstand, during which the plain is mainly influenced by the fluvial process. The comparison between 14C and OSL ages in the Chaoshan plain suggests that 14C ages older than 35 cal ka BP need to be re-evaluated. However, the OSL dating method proves reliable for establishing a comprehensive chronological framework for the late Quaternary sediments in this area.

“…Nowadays, it appears important to reconsider sediment geochemical data from the perspective of compositional data analysis (Flood et al 2016;Buccianti et al, 2018. However, granulometric analysis has a very limited application; only a few studies from the Sundarban and Southeast China coasts have used this procedure (Flood et al, 2015;Tang et al, 2018). A composition is de ned as a sample space for the normal unit D simplex, S D , consisting of a vector of D positive elements adding up to a speci ed constant k, which is generally set to 1 (proportions) or 100 (percentages) by closure (Chayes, 1971).…”

“…As a result, reliance on sedimentary facies analysis in subsurface settings poses a signi cant challenge. By evaluating compositional data analysis associated with a multivariate statistical approach, some researchers provide a methodological framework for studying sedimentary facies using grain size variation (Flood et al, 2015;Puy et al, 2018;Tang et al, 2018). This study examines how the Chandipur coast's back barrier marsh (after classi cation by Allen, 2000) has evolved over time.…”

It is crucial for policy makers and environmental managers to determine the future dynamics of coastal wetlands, especially the existence of their response, disruption, and recovery regimes. Reconstruction of meso-scale evolution in coastal ecosystems can help to adapt coastal resource management techniques to the natural scales of system activity, thereby encouraging true biodiversity. This research provides an overview of decadal (mesoscale) geomorphic transition by high-resolution grain size analysis of a sediment deposit from a barrier estuary regime on the Chandipur coast, India. Coastal marshland’s grain size distribution (GSD) has generally been analyzed using End Member Mixing Models (EMMA) and Probability Density Function (PDF) methods (e.g. log-normal, log skew-Laplace). Although these techniques do not consider the compositional nature of the records, which can undermine the outcomes of the interpretation of sedimentary deposits. The approach to reliable granulometric analysis of lithostratigraphic sequences aims at establishing direct links between fluid dynamics and subsequent shifts in the texture of sediments. In this study, GSD analysis of marsh sediment is represented by compositional data analysis (CoDa) and a multivariate statistical framework. Barrier estuary evolution, presented by time lapses of satellite maps coupled with grain size and carbon content of marsh sediment, primarily reflects the evolving hydrodynamics of the back barrier area. These findings will provide a statistically robust analysis of the depositional system in coastal marshland. Multiannual environmental variations in the back barrier configuration illustrate the importance of this applied approach with respect to bridging the basis of estuarine evolution and process information.
