Principles of Luminescence Dating
91–97 m in core ZK002 are terrestrial swamp facies, composed of dark gray silt and clay with fine sands. Contaminant carbon such as humus probably causes an underestimation of the 14C ages of plant remains underestimation at a depth of ca. 91–96 m in terrestrial swamp facies. Finite 14C ages within these layers do not determine depositional dates because they may be intrusive or residual from bioturbation and post-depositional processes.

Dates of 30,000 years ago to 100,000 years ago are given for this terrace’s sediments. Report the greatest number of MIS 5 dates centered on about 109±4ka. They interpret this as indicating that the peak of fluvial activity occurred somewhat later in the previous interglacial than indicated at Lake Eyre.

Recent studies hypothesize that carbon released by this mechanism impacts global climate, particularly during large igneous province emplacements. However, the direct impacts of sill intrusion, including carbon release, remain insufficiently quantified. We estimate 3.30 Mt of carbon were released due to this sill intrusion, representing an order of magnitude less carbon than inferences from outcrops and modeling would predict. This attenuated carbon release can be attributed to shallow intrusion and the high heat capacity of young, high-porosity sediments. Shallow intrusion also impacts sub-seafloor carbon cycling by disrupting advective fluxes, and it compacts underlying sediments, increasing potential carbon release in response to subsequent intrusions.
In addition, the basal Quaternary deposits from core ZK002 were used to establish a new lithostratigraphic unit named the Paotai Formation in the Chaoshan plain (Ling et al., 2021). While the main objectives of this study are to explore the practical detection limit of 14C dating using plant remains and to determine the age of onset of Quaternary deposition in the area. The effect of thermal excitation on paramagnetic defects in natural sedimentary quartz irradiated with different doses of gamma radiation was studied using electron spin resonance spectroscopy. Ferrihydrite and Fe2+/Fe3+ ratio were higher in soils from the pits compared to samples originating from the mounds and this ratio increased with increasing depth.
