The Middle Pleistocene Great Lakes Period in Otindag Dune field Revealed by Optical Luminescence Dating
Listed in Teesside University Research Data Repository
This dataset includes luminescence dating data, grain size, and scanning electron microscope (SEM) images of quartz obtained from [sampling site/region], collected for the purpose of chronological reconstruction and paleoenvironmental interpretation. 1.
Description
Luminescence Data: The dataset contains raw and processed optically stimulated luminescence (OSL) data obtained using the Single-Aliquot Regenerative-dose (SAR) protocol and the thermally-transferred OSL (TT-OSL) protocol.
Measurements were conducted on purified quartz extracts using a Risø TL/OSL DA-20 reader equipped with blue LEDs (for SAR-OSL) and infrared stimulation capabilities (for TT-OSL). Equivalent dose (De) values OSL decay and growth curves The preheat plateau and the dose recovery and recycle ratio test Equivalent dose distribution The data are provided in .xlsx format and include sample IDs, geographic coordinates, burial depths, and dose rate parameters. 2.

Grain Size Data: Laser diffraction grain size analysis was performed on bulk sediment samples to characterize the depositional environment and infer paleoclimatic conditions. The dataset includes: Grain size distribution Statistical parameters Data are provided in .xlsx format. 3. SEM Images: High-resolution SEM images of quartz grain surfaces were obtained to assess surface microtextures indicative of sediment transport history and exposure.
These images are provided as .jpg files.
