Summary: Coastal morphodynamics and environmental changes are significantly influenced by global warming, sea-level fluctuations, and human activities. Palynological analysis provides important information on vegetation, climate, and environmental change during the Holocene. Detailed analyses from the Pearl River Estuary show marine transgressive processes, vegetation distribution, and climate variations during different stages of the Holocene.

Summary: The research reveals the vegetation and climate changes on the northeast Tibetan Plateau since the Holocene, indicating different climatic and vegetation conditions during different stages over the past 14.2 thousand years, especially the presence of a climate optimum during the mid-Holocene.

Summary: This study presents a quantitative Holocene mean annual air temperature record based on a branched glycerol dialkyl glycerol tetraethers calibration from a small remote alpine lake on the southeastern Tibetan Plateau. The record reveals a temperature history showing a relatively cool early Holocene followed by a warmer mid-to-late Holocene, likely associated with increasing local annual insolation and greenhouse gases. Additionally, three cold events were identified, which correspond in time to ice rafting events in the North Atlantic, and episodes of volcanism and/or unusual solar activity.

Summary: This paper presents a systematic study on Miocene-Holocene alkali basalts at the southeastern margin of Southeastern Tibetan Plateau. The results indicate that these basalts are comparable to the Cenozoic mantle-derived magmatism in Southeast Asia and may have originated from the Hainan plume.

Summary: This paper presents a high-resolution palynological analysis of sediment cores from Lake Ayakum in the northern Tibetan Plateau to understand regional climate fluctuations and their driving mechanisms. The analysis reveals different pollen assemblage zones representing different climate stages, with herbaceous species dominating the pollen spectra. The findings suggest that the climate changes in this region were primarily triggered by the North Atlantic Oscillation phases through south-north migrations of the mid-latitude westerlies during the late Holocene.

Summary: It is confirmed that soil gas geochemistry, including Rn and CO2 fluxes, can serve as reliable indicators for fault activity. In this study, the relationships among soil gas Rn and CO2 fluxes, hydrochemistry of hot springs, and fault activity along the Xiaojiang Fault Zone in SW China were thoroughly investigated. The results indicate that the types of hot spring water were affected by the interactions with groundwater and carbonate rocks. The concentrated distribution of relatively high soil gas Rn and CO2 fluxes in the northern and southern segments of the fault zone corresponded with the spatial distribution of seismic activities and fault slip rate.

Summary: Late Quaternary river blockage events in the mountainous regions of the southeastern Tibetan Plateau are commonly triggered by tectonic and glacial activity. The formation of a paleolake and subsequent damming events were influenced by climatic changes and geological activities. The study suggests a possible connection between a paleoearthquake and the damming event in the region.

Summary: The study focuses on the faulting behavior of the Xigeda fault in the southeastern Tibetan Plateau. It reveals that the fault is active in the Holocene and capable of generating M >= 7.0 earthquakes, playing a significant role in accommodating crustal deformation in the region.

Summary: Remote alpine lakes, with limited human activities, are valuable for studying lake environment evolution in response to climate change and atmospheric deposition. This study reconstructed the water quality evolution of Lake Jiren on the Tibetan Plateau over the past two centuries and identified the drivers behind this evolution. The results showed that the water quality remained relatively pure until 1947, but deteriorated afterwards due to eutrophication and petroleum contamination. This deterioration was primarily driven by increased anthropogenic emissions and atmospheric transport of reactive nitrogen, petroleum products, and heavy metals. Eutrophication induced by nitrogen deposition and climate warming were identified as the main factors behind the water quality deterioration.

Summary: The research focuses on multi-proxy analysis of sediment core from sebkha Mhabeul in southeastern Tunisia, providing a high-resolution sedimentary record back to the mid Holocene. By integrating sedimentary facies, elemental geochemistry, magnetic susceptibility, and tephrochronology-based age model, the study reconstructs hydrological and climate changes in the region. The findings show alternating episodes of arid and wet climatic conditions from the Bronze Age to the present, with evidence of sandstorm events impacting redox-sensitive elements.

Summary: This study used laser ablation-inductively coupled plasma-mass spectrometry to investigate the growth patterns of Micropogonias furnieri otoliths from southeastern Brazil. Comparison of archaeological and modern otoliths revealed a shift from freshwater/brackish to brackish/marine environments in M. furnieri off southeastern Brazil. The analysis also suggested that both modern and archaeological M. furnieri are estuarine fish that utilize marine waters adjacent to the coastal zone.

Summary: This research introduces an advanced object-based geochemical graph learning approach called OGE, which improves anomaly recognition quality and outperforms other models in anomaly detection, as demonstrated in a case study on stream sediment samples in the Bayantala-Mingantu district in North China.

Summary: The geochemical composition and magnetic susceptibility of three sections in the central Chinese Loess Plateau were analyzed to reconstruct changes in weathering intensity and Asian monsoon evolution. The results show distinct differences in element composition between the loess and paleosol layer, reflecting changes in temperature and precipitation. The provenance of the loess-paleosol sequences was constant over time and space. The degree of chemical weathering is relatively weak in the study area.

Summary: The study shows that the moisture on the north-eastern Tibetan Plateau has steadily increased throughout the Holocene, possibly mainly influenced by the Westerlies rather than the Asian Summer Monsoon. However, in the mid-Holocene, the combined effects of the intensified Asian Summer Monsoon and Westerlies may have led to a significant increase in moisture.

Summary: This study analyzed the elemental geochemical properties of sediment profiles in Hudong Sandy Land and compared them with modern basin sediments and Late Quaternary aeolian deposits. It was found that the sediments in Hudong Sandy Land have similar compositions to modern basin sediments and exhibit distinct characteristics from lacustrine sediments. The findings provide insights into the interaction between the East Asia summer monsoon and East Asia winter monsoon/westerlies.
