Stefano Mazzoli (Università degli Studi di Napoli Federico II)

We hope you will be able to join us and look forward to seeing your contribution in the session!

Additionally we would like to invite you to participate to a field-trip to the West-Carpathians also co-sponsored by IGCP 574, and IGCP 597

Organisers: Stefano Mazzoli, Leszek Jankowski, Massimiliano Zattin and Rafał Szaniawski

Session description:

Between 300 and 200 million years ago, all of the Earth's continents were assembled into the most recent giant supercontinent: Pangaea. Pangaea included an eastward-opening wedge-shaped ocean called Tethys, and was surrounded by a superocean, Panthalassa. The formation and subsequent modification of collisional orogens attended the formation and break-up of Pangaea. Some of these orogens show significant curvature. Examples include the Kazakhstan and Calabrian oroclines, and the S and Z shaped Iberian and Carpathian coupled oroclines of the Variscan and Alpine orogens, respectively.

There is a debate about: (a) the timing of assembly of the constituent pieces of Pangaea; (b) how and where these pieces amalgamated and dispersed (the Pangaea A vs B vs C debates); and (c) the mechanisms of Pangaea breakup, (d) the relationship of these processes to oroclinal evelopment and (e) the processes responsible for, and timing of, the formation and subsequent destruction of the Tethys ocean. Remnants of the Tethys now occur along the margins of the Mediterranean, Black and Caspian seas, as well as in the Alpine-Himalayan and adjacent orogens. In this session we explore the potential geodynamic relationship between the geological evolution of the Tethyan realm and the tectonic and paleogeographic evolution of Pangaea.

This session welcomes contributions dealing with Tethyan geology, the evolution of Pangaea and associated curved mountain belts and is sponsored by IGCP 574, Bending and Bent Orogens, and Continental Ribbons and by IGCP 597 Amalgamation and Breakup of Pangaea: the type example of the supercontinent cycle.

Abstract submission deadline is 09-Jan-2013.

Field Trip description:

In the heart of Europe, the Western Carpathians represent not only a classic hydrocarbon province, but also a well studied but still controversial collisional mountain belt. These mountains provide us with the opportunity to analyze some of the fundamental tectonic processes involved in the development of an accretionary orogen. By visiting a series of outcrops located in Slovakia and Poland, the field trip will address topics including: (1) the tectonic relationship between basement nappes (the Inner Carpathians) and the foreland fold and thrust belt (the Outer Carpathians); (2) mélange formation (the Pieniny 'Klippen Belt'); (3) the role of structural inheritance and of the original paleogeographic setting; (4) the nature and context of syntectonic sedimentation; (5) exhumation rates and processes; and (6) the significance of post-orogenic processes. Outcrops will include:

– Rocks belonging to all the main tectonic domains of the Western Carpathians will be touched during the 5-days field trip. A large thermochronometric database, acquired by the field trip leaders during the last few years, allows constraining tectonic burial conditions and timing of exhumation of the various tectonic units that will be visited.

– Basement and Mesozoic cover of the Inner Carpathian domain will be visited in the Mala Fatra region of Slovakia.

– The tectonic melange constituting the so-called "Pieniny Klippen Belt" will be visited in the Orava Lake region, around the Slovakia-Poland boundary. In this area, outcrops of the Inner Carpathian Paleogene Basin ("Podhale Basin") will also be visited.

– The main sedimentary units of the Outer Carpathians will be visited in a series of outcrops located in Poland, moving from west to east. Stops will allow examining classic tectonic windows (e.g. Mszana Dolna), main exposed tectonic contacts, stratigraphy and internal deformation of the thrust sheets.

– The field trip will end with the visit of the Wieliczka salt mine in the Cracow area.

The field trip will start in Vienna on Saturday, April 13th, in the morning and will end in Krakow on Wednesday, April 17th, in the evening.

Transport will be by two (for a maximum attendance of 26 people + 4 field trip leaders), 15-seater minibuses.

Cost: 500 euros/person.
