AB  - The Darnó Unit within the Zagorje-Mid-Transdanubian Megaunit is an allochtonous part of Dinarides in NE-Hungary and represents a relict of the Neotethyan accretionary complex. It contains blocks of submarine basalts of Triassic age in turbiditic sediments (olistrostrome) of Jurassic age. The lava clogged in the lime mud at the original site ofvolcanism and developed closely packed pillow, pillow fragment hyaloclastite breccia, and peperite facies. Interaction between the lava and the sea water produced mostly chloritic alteration of basalt and precipitation of hydrothermal calcite in amygdales, feeding channels of lava lobes and hyaloclastite breccia cements. Calcite is associated with chlorite, epidote, hematite and pyrite. Fluid inclusions in calcite infillings record conditions of fluid/rock interaction. Salinities of fluid inclusions (3.2-5.6 wt.%. NaCl equiv. wt.%.) are close to the salinity of recent sea water and their homogenization temperatures are in the range of 80-150°C. Fluid inclusion data support interpretation that volcanic fades represent rapidly cooled distal zones away from the submarine volcanic centre. This is also confirmed by the comparison to the volcanic and hydrothermal alteration facies of the submarine basalt lava-flow complex and associated pillow lava formation of Triassic age in the Hruškovec quarry in the Kalnik Mts., NW-Croatia. The obtained data contribute to understanding of the early history of Neotethyan evolution, i.e. dilemma about rifting or oceanization in Triassic time and offer new aspects of correlation between units of Dinaridic origin which had been displaced from their original setting by large scale Tertiary tectonic processes.

AB  - Mesozoic igneous rocks occur in various tectonic units of the Intra-Carpathian Area of Eastern Europe. These rocks were situated several hundred km apart from one another during their formation, and subsequent large lateral displacements resulted in their present positions. They formed during a relatively wide temporal range (Middle Triassic to Late Cretaceous) through different petrogenetic processes associated with the Mesozoic evolution of the northwestern part of Tethys. In the Transdanubian subunit of the Alcapa block, Middle Triassic calc-alkaline, intermediateto-acidic, and potassic rocks occur as pyroclastics, lava flows, and dikes in the Bakony and Buda mountains. The Gemer-Bükk subunit of the Alcapa block comprises two different igneous series: (1) slightly metamorphosed Middle Triassic volcanic rocks of the Eastern Bükk Mountains, which can be divided into an older (Anisian-Early Ladinian) calc-alkaline, intermediateto-acidic volcanic series and a younger (Late Ladinian) alkaline basaltic series; and (2) two series of the Middle Triassic to Middle Jurassic ophiolite complex (Bódva Magmatic Series and Darnó-Szarvaskö Magmatic Series), embedded in a tectonic mélange and in an olistostrome suite along a SW-NE-oriented zone. The Tisza block contains Early Cretaceous alkaline volcanic rocks in the Mecsek-Alföld subunit. Strong temporal and geochemical correlations have been observed between the Middle Triassic volcanic rocks of the Bakony and Buda mountains and the Southern Alps, and those of the Eastern Bükk Mountains and the Outer Dinarides. We propose that all these rocks were formed during the same extension-related volcanic activity along the Southern Alps-Bakony and Buda mountains-Eastern Bükk Mountains-Dinarides region. The Middle Triassic-Middle Jurassic ultramafic-mafic igneous rocks of the Gemer-Bükk subunit can be correlated with the ophiolites of the Inner Dinarides. Geochemistry of the mafic rocks is consistent with an origin from an N-MORB and E-MORB source mantle. The Middle to Late Triassic ultramafic and mafic rocks of the Bódva and Darnó-Szarvaskö series could have originated along the mid-oceanic ridge system of the northwestern segment of the Vardar ocean (Meliaticum). The Middle Jurassic igneous rocks of the Darnó-Szarvaskö series could have corresponded to the opening of a backarc basin. Early Cretaceous alkaline volcanic rocks of the Mecsek-Alföld zone in the Tisza block formed as a result of continental rifting along the southern margin of the European plate. Two volcanic series - a mafic and a sodic group - were generated from an OIB-like asthenospheric mantle. Separation of the Tisza block from the European plate occurred contemporaneously with volcanic activity during the late Early Cretaceous.

AB  - The Darno Conglomerate and the Petervasara Sandstone with conglomeratic intercalations, both cropping out in northern Hungary, were formed along the eastern margin of the shallow Early Miocene sea within the Carpathian are. Ophiolite-derived elastic components in both formations indicate a close genetic relationship with each other and with the activity of the basin-margin Darno Fault, which seems to correspond with the coeval shoreline. The Darno Conglomerate was part of a small fault-controlled fan-delta supplying coarse clastics into the sea where the Petervasara Sandstone deposited. The conglomerates occur as small lobes interbedded within a field of tidally-driven sand waves. The coarse-grained clastics, which were admired to the main material of the sandstone, have been derived from Triassic-Jurassic ophiolite-related series (Meliata nappes) east of the Darno Fault. The composition of the lobes indicates that they were formed as small spit-like platforms attached to the fan-deltas of the Darno Conglomerate. As base level rose spits became drowned and their sediment was washed into the basin and reworked by the strong northward-directed tidal currents into elongated lobes 'mimicking' sand waves. A reduction in the amount of the less resistant pebble components of ophiolite-related origin and a relative enrichment of the resistant components towards the west indicate that pebbles had partly been transported in the offshore direction. The increasing rate of accumulation of ophiolite-derived heavy minerals and pebbles along the northern part of the coast indirectly suggests a contemporaneous left-lateral displacement along the basin-margin Darno Fault.

AB  - The Outer Carpathian flysch nappes encircle an Intra-Carpathian domain
which can be divided into two megatectonic units (North Pannonian and
Tisza) mostly on the basis of contrasting Mesozoic and Palaeogene
facies development. We see two major kinematic problems to be solved:
(1) The present distribution of the Mesozoic and Palaeogene facies is
mosaic-like, and some belts form exotic bodies within realms of
Austroalpine affinity. (2) Late Eocene palinspastic reconstruction of
the Outer Carpathian flysch nappes suggest, that the entire
Intra-Carpathian area must have been located several hundreds of
kilometres to the south and to the west of its present position.
Neogene extension can account for shortening in the external Carpathian
nappes, but is unable to explain Mesozoic facies anomalies and offsets
of Palaeogene formations. We suggest that evolution of the
Intra-Carpathian area involved first Late Palaeogene-Early Miocene
juxtaposition of the North-Pannonian and Tisza megatectonic units,
accompanied by the closure of the external Carpathian flysch troughs;
thereafter extension of this amalgamated unit occurred, which was
compensated by thrusting of flysch nappes onto the European foreland
and formation of molasse foredeeps.
Eastward escape of the North-Pannonian unit from the Alpine collisional
belt involved left lateral shear along the Pieniny Klippen belt and
right lateral shear along the Mid-Hungarian zone. Parts of the Late
Palaeogene basin and an Early Miocene volcanic edifice were dissected,
offset and elongated by several 100 kms. The driving mechanism of the
eastward escape of the Intra-Carpathian area can be related to the
collision of Apulia and Europe and the subduction of the external
Carpathian crust under the Pannonian units. The escape ceased gradually
in the Early Miocene, when oblique collision between the
North-Pannonian unit and European continent occurred.
Neogene extension of the Pannonian region was an areal deformation. The
extension at locally variable rate resulted in the break-up of the
heterogenous floor of the Neogene basin.
The driving mechanism of basin extension and contemporaneous
compressional deformation of the external Carpathians is thought to be
related to ongoing subduction, involving the marginal part of the
attenuated European continental crust. Tectonic activity in the
Carpathians and basin subsidence and volcanism shifted in time and in
unison from the west toward the east-southeast.

AB  - The evolution of the Meliata-Hallstatt ocean and of its southern and northern margin in the Inner Western Carpathians are described. The main rifting began during the Pelsonian and the sea-floor spreading ended at the beginning of the Middle Carnian contemporaneously with the Raibl event. The subduction began in the latest Triassic and the final closing of the ocean, accompanied by uplift of the adjacent marginal areas, was dated as basal Oxfordian. Remnants of the oceanic-suboceanic sequence occur in two tectonic positions: (1) Obducted nappes that contain, mostly as tectonic melanges, the whole Middle Triassic to Middle Jurassic sequence, including large bodies of dismembered ophiolites of Ladinian to Early Carnian age. (2) Evaporite melanges at the base of nappes that are derived from the northern margin of the ocean. These evaporite melanges consist of Late Permian evaporitic matrix and blocks of a dismembered Ladinian to Lower Carnian ophiolitic sequence. In the Inner Western Carpathians both the northern and southern marginal sequences of the Meliata-Hallstatt ocean and the transitions into the carbonate platforms are present in different nappes. The southern marginal development is characterized by Middle Carnian distal clastic Raibl Beds and by Middle Jurassic rhyolithic volcanism, both missing in the northern marginal development. Because the subduction-related Middle Jurassic volcanism (contemporaneous with the turbidites in the southern Meliaticum) is restricted to the marginal area south of the Meliata-Hallstatt ocean, southward-directed subduction is indicated. To the south, on the adjacent carbonate platform, a Jurassic basin with Aalenian to Bajocian ophiolites opened. This may be a back-arc basin. In the Eastern Alps only the northern marginal zone and the adjacent carbonate platform are preserved, but parts of the dismembered ophiolites in the Haselgebirge may be of Ladinian to Late Carnian age like in evaporitic melanges in the same tectonic position in the Inner Western Carpathians. The final closing of the Meliata-Hallstatt ocean is indicated by the abrupt end of the turbiditic sedimentation in the oceanic suboceanic domain and by uplift in the marginal areas, where Lower Oxfordian radiolarites are overlain by shallow-water Upper Oxfordian to Tithonian or Neocomian limestones (Silica Nappe, Hallstatt Nappes). With the evidence of the final closing of the Meliata-Hallstatt ocean near the Middle/Late Jurassic boundary, the Cimmerian orogenesis (in the genetic sense of Sengor, 1984, 1985) is now also proven in the Inner Western Carpathians and in the Eastern Alps. A continuation of the Meliata-Hallstatt ocean into the Pontide ''Paleotethys'' (= Cimmerian ocean sensu Kozur, 1990) through the Transylvanian oceanic domain and the Strandzha Unit is assumed. A connection with the Vardar ocean is impossible, because in the Vardar Zone no Triassic ophiolites or basic volcanics are present and the ophiolites have Jurassic age.
