â â â  â  â â â â â â â  abstract â  the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian – santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...

Purpose. The research purpose is to increase the efficiency of borehole uranium mining by selecting special decolmating solutions and rational parameters technology for influencing seam near-filter zone geotechnological boreholes, as well improving filtration characteristics seam, depending on mineralogical composition ores structure sediment-forming materials. Methods. method X-ray phase analy...

The Late Cretaceous to Cenozoic is known for its multiple inversion events, which affected Central Europe's intracontinental sedimentary basins. Based on a 2D seismic profile network imaging the basin fill without gaps from base Zechstein seafloor, we investigate nature and impact of these events salt structures in Baltic sector North German Basin. These insights improve understanding structure...

To assess the influence of growing salt structures on facies distribution, stratal pattern, and thickness trends, this paper provides tectonostratigraphic framework outstandingly exposed Cotiella minibasins (South-Central Pyrenees, Spain). Based detailed analysis field cross-sections, our results showcase syn-halokinetic upper Coniacian-lower Santonian infill (1.5–3 km thick) records four shall...

dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation ...

The Cenomanian–Turonian boundary (CTB) on the intra-Tethyan Adriatic Carbonate Platform (AdCP) is generally characterised by a transition between microbially laminated and/or bioclastic limestones to calcisphere-rich massive limestone with bioturbated intervals, organic-rich interbeds, firmgrounds, as well neptunian dikes, carbonate turbidites, tempestites and slumped structures. Compilation of...

An analysis of joint patterns were carried out on multiple exposures in Albian to Turonian strata belonging the Abakaliki Formation (Asu River Group) and Eze-Aku (Eze-Aku eastern flank Anticlinorium Southern Benue Trough. The was using FracPaQ a MATLAB based toolbox for quantification fracture patterns. tool used calculate density, intensity traces; quantify scaling distributions, determine dil...
