Welcome to the "Wandering Underground" Petrochronology laboratory of the University of Bucharest. The laboratory was designed by a few geology enthusiasts in the Geology Department and benefited from the help of the UB administration particularly Prof. Dr. Carmen Chifiruc, the University Provost and her team. Mirela Serban was a critical player in the acquisition stage. The University President , Prof. Dr. Marian Preda was extraordinarily supportive and we benefited from various internal resources made available by his excellence. None of this effort would have been possible without the diligent and expert aid of the department chair, Prof. Dr. Lucian Petrescu, who was the singlemost important facilitator of the laboratory development. The proposal written for the Ministry of Research in July 2021 was awarded funding in Dec 2021 and the acquisition took place in 2022-2023. Space preparation was completed in Oct 2022 and the installation of the Themo ICP-MS was accomplished in Dec 2022. The Teledyne Laser ablation system was installed in May-June 2023.
