VelingaraData : geophysical and zircon data acquired in the Velingara circular depression (Senegal)

The Velingara dataset gathers geophysical and zircon data acquired in the Velingara circular depression (Senegal). In March 2022, a field campaign was performed in this depression, since it is thought to be an impact structure. Magnetic and gravity field observations were done, as well as sampling. Several zircon grains of sample VEL29A were analysed by LA-ICP-MS, given an age of 550 Ma.

韦林加拉（Velingara）数据集收录了在塞内加尔韦林加拉环形洼地采集的地球物理与锆石（zircon）数据。2022年3月，因该洼地被认为是一处撞击构造，研究团队在此开展了野外调查工作，同步完成了磁法观测、重力场测量与样品采集作业。针对VEL29A号样品中的多颗锆石颗粒，采用激光剥蚀电感耦合等离子体质谱法（LA-ICP-MS）进行了分析，测得其形成年龄为550 Ma。
