Single-zircon evaporation datings of three porphyritic clasts from the Malmback conglomerate yield ages of 1796pm8, 1807pm7, and 1811pm11 Ma. The precursors of the reworked volcanics are interpreted as Småland-Varmland igneous rocks of the Transscandinavian Igneous Belt (TIB). Two granites, located east and west of the conglomerate, give ages of ca. 1700 and ≥1780 Ma, respectively. The coexistence of the ca. 1800 Ma old granite and reworked volcanics (the conglomerate clasts) of similar age is suggested to reflect an extensional tectonic setting during the earliest TIB magmatism, although the overall tectonic regime may have been compressional. |
