Neodymium (Nd) isotopes, tracers of seawater composition and mixing, measured in calcitic bivalve shells and calcitic micrite from the Middle Miocene deposits in Poland and Ukraine, were used to reconstruct the seawater circulation and the evolution of seawater geochemistry in the Fore-Carpathian Basin, the northern peripheral part of the Paratethy...

Comprehensive knowledge of both the primary and secondary mineral composition of rocks, as well as the diagenetic processes occurring within them, stands as a fundamental requirement for accurately estimating reservoir rock parameters across various geological sectors, such as petroleum geology, geothermal energy, and carbon capture and storage. In...

In this study, we focused on magnetic characterization and determination of the spatial extent of hydrocarbon migration pathways. The chosen study area was traditionally known as the first oil production site in history - „Pusty Las” (Sękowa village), where well-documented seepages and historical boreholes were present. The reservoir rock was Inoce...

Neodymium (Nd) isotopes constitute a versatile tracer frequently used in oceanography to identify water masses and track their circulation, both in the modern and ancient oceans and seas. In this research, for the first time, primary marine gypsum is being used as a new archive preserving Nd isotope signatures of past seawater and brines in very sh...

The Oligocene Menilite Beds are considered the most important source rock for hydrocarbon accumulation in the Polish Carpathian region, whereas the Cretaceous Lgota Beds have been regarded as an additional potential source rock. Understanding their petrophysical and geochemical properties is essential for evaluating the hydrocarbon potential of the...

Located on the northern Vietnam onshore/offshore transition, the Hoanh Bo Trough is an excellently exposed terrestrial Palaeogene sedimentary sequence that may be treated as an analogue for regional interpretations of the sedimentary and structural evolution of the northern Song Hong Basin. The Hoanh Bo Trough lies to the north of the northern Song...

Middle Miocene crystals of sabre gypsum and subcrystal of giant gypsum intergrowth cropping out in southern Poland near Busko have been analysed for their Sr isotope composition. The new isotopic data revealed fluctuations in Sr/ Sr values within the primary gypsum crystals providing new insight into paleohydrological conditions during the Badenian...

In North Vietnam, the NW-SE faults play an important role for geotectonic, including the Red River and Cao Bang-Tien Yen Fault Zones (Fig. 1). The Yen Bai Basin (YBB) (Fig. 1 and Fig. 2C) was formed along the Red River Fault Zone (RRFZ), which is the key tectonic structure separating South China from the Indochina block (Fig. 2A and B). Parallel to...

During the Miocene-Pleistocene, generally sub-tropical to tropical warm and humid paleoclimate prevailed in Southeast Asia with a gradual cooling trend. The Truc Thon clay (TTC) mine presents interesting outcrops for sedimentological and provenance analysis. The present study uses results of geological investigation in 16 outcrops and wells at the...

We test the hypothesis of a major Paleogene river draining the SE Tibetan Plateau and the central modern Yangtze Basin that then flowed South to the South China Sea. We test this model using U-Pb dated detrital zircon grains preserved in Paleogene sedimentary rocks in northern Vietnam and SW China. We applied a series of statistical tests to compar...

The anisotropy of magnetic susceptibility is a well‐known geological proxy in revealing the directional tectonic and sedimentological features of rocks, although it can be ambiguous in situations where these two factors co‐occur. This paper demonstrates the usefulness of the anisotropy of magnetic susceptibility in determining palaeotransport direc...

The Cao Bang-Tien Yen Fault (northern Vietnam) is subparallel to the Red River Fault Zone. The fault-controlled Cao Bang, That Khe, Lang Son and Na Duong Basins along the Cao Bang-Tien Yen Fault are filled with thick series of terrestrial deposits.

The irregular distribution of sand injections, traditionally termed ‘dykes’ in the Polish geological literature, within individual Carpathian units and within individual lithofacies were observed during long-lasting field works. Injectites have been observed in the Magura Beds and in the Inoceramian Beds of the Polish and Romanian Carpathians, and...

The aim of this study was to reconstruct the location mechanism of a Triassic sandstone wedge within folded Palaeozoic rocks. A vertically oriented Buntsandstein succession (Lower Triassic) from Józefka Quarry (Holy Cross Mountains, central Poland), steeply wedged within folded Devonian carbonates, is recognised as an effect of normal faulting with...

GPR method is perfectly suited for recognizing of sedimentary facies diversity in shallowly occurring sediments if there is a contrast of electrical properties between and/or within each layer. The article deals with the issue of the correlation between GPR surveys results and sedimentological analyses. As a result of this correlation a conceptual...

We would like to thank Przemysław Gedl for his attention in reading our work and for the discussion he initiated (Gedl, 2018). First of all, we would like to note that our reply will concentrate on substantial comments on the presented results or/and questionable interpretations.

The Neogene sedimentary succession of the Orava-Nowy Targ Basin directly overlies the Central Carpathian Paleogene Basin deposits, the Magura Unit, and the Pieniny Klippen Belt. It provides an excellent geological record that postdates the main Mesoalpine structural and geomorphological processes in the Western Carpathians. Sedimentological, petrog...
