Kurzbeschreibung des Verlags

Triassic palynostratigraphy from on- and off-shore wells and surface of the Croatian eastern Adriatic (Adria microplate) suggests continuous Ladinian-Rhaetian sedimentation of evaporites and dolomites as recorded in the reference Vlasta-1 well.Correlation of Vlasta-1 with coevals from N America, Europe, circum-Mediterranean and NW Australia revealed good compliance.During the Ladinian-Rhaetian, Adria microplate was characterized by stable (semi-)arid climate.Sub- and surface Ladinian tuff bearing sediments contain reworked Permian-early Anisian palynomorphs due to depositional conditions created on Adria during the Ladinian aborted rifting phase.The Triassic of Vlasta-1 reflects primary depositional relationships of the central Adriatic sub- and surface lithostratigraphically contemporaneous deposits before being deformed by the Ladinian-middle Carnian halokinetic facies as recorded in Vlasta-1.Surface occurrences of basalt-andesite boulders in the central Adriatic are related to diapiric structures because the effusions were syngenetic with the Ladinian part of the halokinetic facies.Halokinetic tectonics is the main source of seismicity in central Adriatic.
