OSL Dataset from coastal dunes below Holocene tsunami deposits, Diu, India

This dataset contains optically stimulated luminescence (OSL) dating results and dosimetric measurements from coastal dunes below Holocene tsunami deposits along Diu Island, western India. The data include equivalent dose (De) values, overdispersion, skewness, and modeled ages (CAM, MAM, weighted mean, and minimum 2σ) for sedimentary sites ISR-Diu (Diu Island). These data were collected as part of a study investigating the chronology and depositional characteristics of Holocene tsunami events to evaluate the reliability of age models in different coastal contexts.

本数据集涵盖印度西部第乌岛沿岸全新世海啸沉积层下伏海岸沙丘的光释光（optically stimulated luminescence, OSL）测年结果与剂量学测量数据。数据包含沉积位点ISR-Diu（第乌岛）的等效剂量(equivalent dose, De)值、离散度、偏度以及多种模拟年龄结果，包括CAM、MAM、加权平均值与最小2σ置信年龄。该数据集为一项研究的采集成果，此项研究旨在探究全新世海啸事件的年代学与沉积特征，以此评估不同海岸环境下年龄模型的可靠性。
