Summary: In this study, the quartz luminescence sensitivity (QLS) properties of eight samples of Permian biotite monzogranite from a borehole in the southern tropics of China were investigated. The degree of chemical weathering did not correspond with the QLS values of samples that have undergone varying degrees of in situ weathering. It was hypothesized that the variation of the irradiation field during the in situ chemical weathering process may affect the QLS, but not considerably within 200 ka. Additionally, it was discovered that quartz from the same source undergoes varying degrees of in situ chemical weathering but has a constant response to irradiation-bleaching cycles (IBCs).

Summary: This study investigates the relationship between astronomically forced climate and sediment accumulation in the Songliao Basin in Northeast China. The sedimentary cycles in the basin are controlled by long-eccentricity, short-eccentricity, obliquity, and precession orbital cycles. Chemical weathering records suggest the existence of paleomonsoon variations in East Asia during the Late Cretaceous.

Summary: This integrated study examined ditch samples from three wells in Lagos area, Nigeria to determine their provenance, heavy mineral composition, lowstand-highstand episodes, Qua-ternary palaeoenvironment, and date lithofacies. The medium to fine-grained sandstones contained fragments of lignite. Petrographic analysis revealed abundant detrital minerals, predominantly quartz, feldspar, and rock fragments. The sandstones were identified as quartz arenites of continental block provenance, deposited under humid climatic conditions. Heavy mineral assemblages and Zircon-Tourmaline ratios indicated matured sediments, while Apatite: Tourmaline ratios showed variations in weathering rates. Sea level changes and fluctuations in climatic conditions during floodplain residence were evident. Sandstones with high ATi values were deposited during relative sea level highstand, while those with low ATi values were deposited during lowstand. The presence of certain plant species revealed a transition from mangrove to fresh water swamp, and the absence of Miocene diagnostic forms indicated late Pleistocene deposition.

Summary: In this study, the major, trace, and rare earth element compositions of the Bijaigarh Shale (BS) were analyzed to infer the composition, weathering history, and tectonic setting of the Mesoproterozoic continental crust. The BS consists of quartz, smectite, kaolinite, and illite, with occasional framboidal pyrites. The high chemical index of alteration (CIA) and plagioclase index of alteration (PIA) values, along with the depletion of certain elements, suggest intense chemical weathering in a warm and humid climate. The REE patterns and immobile element ratios indicate a felsic provenance, with insignificant recycling. The source area is estimated to consist of various granite types and Porcellanite.

Summary: The study evaluated the influence of photo-oxidation on the quantification of isotactic polypropylene by Pyrolysis Gas Chromatography/Mass Spectrometry. The degradation rate of fragments was found to be three times faster than beads, likely due to their larger surface area. Additionally, polypropylene subjected to harsh weathering conditions may be underestimated by 42% to 49% when quantified using Pyr-GC/MS with virgin polypropylene calibration standards.

Summary: This study investigates the impact of pre-depositional factors on the sandstone composition in Mid-Carboniferous deltaic sandstones. Variations in the apatite-tourmaline index values in different depositional environments suggest differences in weathering intensity due to variable duration of alluvial storage. The study also observes fluctuations in the rutile-zircon index, potentially indicating variable supply from a source rich in rutile but poor in zircon and apatite. Despite partial derivation from recycled sources, the apatite-tourmaline index still appears to hold information on the last sedimentary cycle.

Summary: Loess provides a valuable record of past environmental conditions and air mass circulation responsible for dust transport. Changes in the luminescence sensitivity of sedimentary quartz and feldspar can be used to identify changes in source in a loess-palaeosol sequence. An empirical investigation found an inverse relationship between quartz and feldspar sensitivity, as well as variability in sensitivity between different quartz grain sizes. The IR50 sensitivity from unprocessed sediments correlated with clay content, while feldspar sensitivity correlated with Si/Al ratios, indicating the potential use of IR50 measurements to track source variability over millennial timescales.

Summary: The study presents geochemical and geochronological analyses of a 60 ka sedimentary record from Brown Lake in subtropical Queensland. The findings indicate a positive trend of dust deposition starting from around 50 ka, with the highest influx occurring leading into the Last Glacial Maximum. An inter-site comparison suggests enhanced moisture stress regionally during the last glaciation and throughout the LGM, returning to a more positive moisture balance around 8 ka.

Summary: This study presents a multiproxy record from the Hashilan Wetland in the central Zagros Mountains, providing insight into the climate change in West Asia over the past 22-2.2 kcal bp. The findings indicate a cold, dry climate during the last deglaciation and amplified aridity during various periods. There was an out-of-phase moisture variation between West Asia and the Indian Summer Monsoon domain, influenced by latitudinal shifts of the Hadley cell driven by summer insolation. The study also explores the potential impacts of these climate changes on prehistoric human communities.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
