Sažetak
This paper presents geological and petrologic data on allochthonous bodies of Mesozoic ophiolites from Mt. Kalnik, which are correlated with coeval ophiolites from the surrounding mountains of the south-western parts of the Pannonian Basin commonly included in the northwesternmost Dinarides. Basalt is associated mostly with Middle-Upper Triassic to Lower Cretaceous interlayered chert, siliceous shale, mudstone and limestone. Mostly Jurassic olistostrome melange, subsequently strongly tectonizes, includes fragments of predominant native graywacke with basalt, diabase, gabbro, amphibolite, serpentinized peridotite, shale, chert, and exotic, stratigraphically varied limestones, which are embedded in a pervasively sheared shaly-silty matrix. Mappable zones of tectonic carbonate megabreccias with fragments of Middle Triassic to Paleocene limestones and dolomites are associated with the tectonized melange. The tectonized melange was probably generated by Eocene final subduction processes. Rock descriptions, major and trace element data for all ophiolites from Mt. Kalnik are given. These and the surrounding ophiolites from the south-western Pannonian Basin can be correlated in many ways with the ophiolitic complexes of the internal Dinarides and Bukk Mts in Hungary. The present geological position of the allochthonous ophiolites is genetically related to postsubduction extension and transcurrent tectonic movements and subsequent normal faulting which caused the formation of the southern parts of the Pannonian Basin.
