- Project GOST at 7th Croatian Geological Congress
The 7th Croatian Geological Congress was held in Poreč from October 2nd-4th. GOST project contributed with six abstracts presented through oral and poster presentations:
Mirko Belak et al. – MIddle Triassic syn-rift rhyolites and rhyolitic ignimbrites on the north-east margin of Adria (NE Slovenia, NW Croatia): possible source of rhyolitic tuffs (Pietra Verde) in the wider Dinaride Area
Tonći Grgasović et al. – From reef to basin – progradaion of the shallow water carbonates over the Middle Triassic Northwestern Croatian Rift Related BAsin (Ivanščica Mt., NW Croatia)
Duje Kukoč et al. – Eary Neotethyan history archived in the ophiolitic melange of NW Croatia
Damir Slovenec et al. – Middle Triassic calc-alkaline basalts and andesites of Ivanščica and Strahinjščica Mts. (NW Croatia): mineralogy, petrology and tectono-magmatic setting of formation
Duje Smirčić et al. – Mid-Triassic volcano-sedimentary successions of NW Croatia – implications for the early evolution of the Adriatic margin
Matija Vukovski et al. – Role of Alpine and Dinaridic tectonic events in the transitional area of the Southern Alps and the Internal Dinarides – kinematic inferences from Ivanščica Mountain (NW. Croatia)
About project GOST
Project “Revealing Middle Triassic Paleotethyan Geodynamisc Recorded in the Volcano-Sedimentary Successions of NW Croatia” (GOST) studies volcanic/volcaniclastic rocks interstratified within Middle Triassic marine sedimentary sequences found on mountains of NW Croatia. The goal is to integrate mineralogical, petrological, geochemical, paleontological, sedimentological, isotopic and structural data to acquire a better understanding of the tectonic history of the investigated area.
Data will be obtained using multiple modern analytical methods and techniques along with radiometric dating. Chemical and mineralogical analyses (ICP-MS, LA-ICP-MS, EMPA, XRD) and isotopic composition of 87Sr/86Sr and 143Nd/144Nd (TIMS, MC-ICP-MS) will give information about the character of the primary magmas, conditions and processes of the genesis of volcanic and volcaniclastic rocks, as well as their geotectonic origin. The crystallization age will be determined by Ar-Ar and U-Th-Pb (LA-ICP-MS) methods.
Processing and synthesis of results will shed light on genesis, characterization and crystallization time of primary magmas. It will furthermore enable reconstruction of the geotectonic setting of the formation of the volcanic rocks and will provide insights into physico-chemical conditions of post-consolidation weathering and diagenetic processes.
Microfacies and geochemical characterization of sedimentary rocks will provide insights into the sedimentation environment of volcanoclastic rocks. Biostratigraphic analyses (e.g. radiolarians, conodonts) will constrain the stratigraphic span of volcanic activity.
The analysis of the structural-tectonic features of the rocks will reconstruct the paleogeographic and geodynamic position of these successions during the Middle Triassic to the present day.
Results will enable new inferences on the occurrences as well as modes, conditions, and time of formation of volcano-sedimentary successions. Such an approach will eventually lead to chronological reconstruction of tectono-magmatic evolution during the inception of Mesozoic, which will serve as the framework for a new petrogenetic and sedimentological model for the middle Triassic.
Project GOST assembled a team of experienced international scientists from different geological disciplines as well as one doctoral candidate.
GOST project is funded by Croatian Science Foundation (HRZZ) for a period of four years. After a successful evaluation process and negotiations, the project started on December 1st 2019.
