Abstract The present study, based on combined geophysical, geochronological and isotopic data identifies a cratonic block which we call the Western Chihuahua-Mesa Central megablock (WCMB) in northern Mexico. New Bouguer and isostatic gravity anomaly maps revealed a conspicuously distinct, spatially-extensive gravity minima over a region extending ...

Emplacement of the megablock zone in the Chicxulub crater, Yucatan, Mexico
2010Strontium isotope stratigraphy applied to the Cretaceous sequence present in the Yaxcopoil core drilled in 2002 in the Chicxulub crater (Yucatan) demonstrates that the megablocks preserved their original pre-impact orientation. No overturned unit has been identified at the level of resolution, setting constraints on the emplacement mechanisms taking ...

AGE OF GRANITES OF THE KROPYVNYTSKO-BOBRYNETSKY MASSIF (INGUL MEGABLOCK OF THE UKRAINIAN SHIELD)
Mineralogical JournalThe uranium-lead isotope systems of accessory monazites from porphyry-like and pegmatoid granites of the Kropyvnytsko-Bobrynets massif (Ingul megablock), which were opened by the Zhyvanivka quarry, located on the left bank of the Sugokleya River, southwest of the village of Zhyvanivka, were studied. For isotopic dating, multigrain monazite samples were

Modelling the Hydraulic Injection Fracture Response in Layered Media for Megablock Experiments
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Finite-discrete element method (FDEM) models were employed to explore the fracturing response of Montney Formation outcrop samples to hydraulic fracturing. Variability envelopes were employed to characterize its behaviour under different compressive loading orientations with respect to the layering in the ...

Monazitometry of the Ukrainian Shield (Volyn and Dniester-Bug megablocks)
he monograph presents the results of uranium-lead isotope dating of multigrain monazite samples from crystalline rocks (granitoids, gneisses, amphibolites) of the Volyn and Dniester-Bug megablocks of the Ukrainian Shield. The mineralogy of monazite and the features of the uranium-lead isotopic system of this mineral are highlighted.openaire +1 more source
