Popis:	The first laser-induced 40Ar-39Ar incremental-heating mineral age data for the Timok Massif of the Banatitic Magmatic and Metallogenetic Belt (BMMB) demonstrate that the main mineralization stage at the giant Majdanpek Cu–Au(–Mo) porphyry deposit took place at 83.6–84.0±0.6 Ma (2σ), coinciding with the later, 83±1–89.0±0.6 Ma, stages of the first cycle of andesitic volcanism. The earliest-Campanian age for hydrothermal activity precludes an association with the later history of the BMMB, and discounts the metallogenetic role of “Laramide” plutonism for the dated deposits.
