Dear Colleagues,
We are pleased to invite you to the 16th meeting of InterRad, the International
Association of Radiolarists, which will be held in September 2022 at ZRC SAZU,Ljubljana, Slovenia.
InterRad promotes all aspects of radiolarian research including taxonomy,ecology, biogeography, biochronology and evolution along with applications instratigraphy and tectonics. The meetings are held regularly every three years
and are aimed to gather radiolarian specialists of different research fields who
present current research and exchange new ideas to advance the understandingof fossil and living radiolarians. The community is not restricted to geologists andbiologists but is open to other scientists who integrate radiolarians in a wide
range of disciplines, such as mathematics, physics and space engineering. Artistsinspired by the fascinating complexity of radiolarian skeletons are also mostwelcome.
In addition to scientific sessions, several excursions will be organized. The preand post-conference excursions will focus on the stratigraphy and geodynamic
evolution of the Northern Calcareous Alps in Austria and the Dinarides inMontenegro, respectively. The mid-conference excursions will visit Kras (theclassical karst area) and the Julian Alps in Slovenia.
We are looking forward to seeing you in Ljubljana

Excursions
Excursion A – Mesozoic tectonostratigraphy of the Eastern Alps
(Northern Calcareous Alps, Austria): a radiolarian perspectivePrepared by: Hans-Jürgen Gawlick (Leoben), Hisashi Suzuki (Kyoto), ŠpelaGoričan (Ljubljana), Luis O'Dogherty (Cadiz).
Duration: 4 days (8–11 September)
Cost: 450 EUR (double room)
Includes: field-trip guide book, transportation, accommodation with breakfast,lunch and dinner.
Participants: Minimum 12, Maximum 40
The topic of the field trip will be the Mesozoic geodynamic evolution of theWestern Tethys with two oceanic domains. The Neo-Tethys realm (1) to thesouth was characterized by Middle Triassic continental break-up, Middle Triassicto Middle Jurassic passive margin evolution, Middle–Late Jurassic
thrusting/accretion and Latest Jurassic/Early Cretaceous mountain uplift. The
Alpine Atlantic realm (2) to the north recorded an Early/Middle Jurassic
continental break-up and Middle Jurassic to Late Cretaceous passive marginevolution. The field trip will focus on deep-water, radiolarian-bearing sedimentaryrocks during this geodynamic history in different basins: rift-basins, shelf areas,
oceanic domains, trench-like basins, foreland basins. The geodynamicallytriggered interplay between carbonate production, siliciclastic/volcanic input anddeposition of siliceous rocks/radiolarites in combination with the asynchrony ofbasin formation allows in specific times the calibration of radiolarians with e.g.,ammonoids, conodonts and calpionellids beside other organisms.
The field trip will be held in one of the most classical areas of the world, thecentral Northern Calcareous Alps with its world-wide known touristic highlights(e.g., Salzburg, Hallstatt).

Excursion B1 – Kras – the classical karst area in SW Slovenia
Prepared by: Karst Research Institute ZRC SAZU
Duration: 1 day (mid-conference excursion on Wednesday, 14 September)
Cost: 80 EUR
Includes: field-trip guide book, transportation, entrance to the Škocjan Caves,lunch.
Participants: Maximum 50
This excursion will be devoted to the area of Classical Karst, where karst
phenomena have been first scientifically described. We will visit the ŠkocjanCaves, a UNESCO world heritage site famous for its spectacular undergroundcanyon and inspiring history of exploration. Second part of the excursion will
focus to the karst hydrology and geomorphology of the Ljubljanica Catchment
Area. This will include intermittent lake of Cerkniško Polje, karst valley Rakov
Škocjan, spring cave Planinska Jama and Planinsko Polje.
Excursion B2 – Geology of the Bohinj area, Julian Alps, NW Slovenia
Prepared by the Ivan Rakovec Institute of Paleontology ZRC SAZU
Duration: 1 day (mid-conference excursion on Wednesday, 14 September)
Cost: 80 EUR.
Includes: field-trip guide book, transportation, cable car to Vogel, lunch.
Participants: Maximum 50
The field-trip area lies in a beautiful landscape of the Triglav National Park. In themorning we will take the cable car to Vogel to observe the overall nappe
structure of the Julian Alps. In the afternoon we will visit Upper Jurassic to Lower
Cretaceous deposits (Biancone limestone and flysch) of the Pokljuka Nappe. On
the way back we will stop at Bled, one of the most popular tourist destinations inSlovenia.
Excursion C – Mesozoic basins of the southern Dinarides, Montenegro
Prepared by: Špela Goričan (Ljubljana), Martin Đaković (Podgorica), Peter
Baumgartner (Lausanne), Duje Kukoč (Zagreb), Nevenka Djerić (Belgrade), TimCifer (Ljubljana), Aleksander Horvat (Ljubljana), Hans-Jürgen Gawlick (Leoben).
Duration: 5 days (16–20 September)
Cost: 550 EUR (double room)
Includes: field-trip guide book, transportation (plane ticket Ljubljana–Podgorica–Ljubljana, bus in Montenegro), accommodation with breakfast, lunch and dinner.
Participants: Minimum 10, Maximum 30
This excursion will show a cross-section through the Dinarides from the mostexternal zones in coastal Montenegro to the ophiolitic mélanges near the borderwith Serbia. The Mesozoic successions reflect a complex horst-and-graben
topography that was created on the continental margin during Middle Triassic
rifting and final opening of the Neo-Tethys. Several basins separated bystructural highs (carbonate platforms and submarine plateaus) have beenrecognized. We will examine the complete Middle Triassic to end Cretaceous
succession of the most external Budva Basin and the Triassic to Lower
Cretaceous succession of a more internal Lim Basin. On the way we will crosshundreds of meters thick successions of platform limestones locally including aMiddle Triassic radiolarite unit. Allochthonous Middle Triassic cherts associatedwith volcanics and Middle Jurassic cherts associated with ophiolitic mélange willbe also visited.
