A reconnaissance geochemical drainage survey of the Criffel-Dalbeattie granodiorite complex and its environs [PDF]
Regional geochemical reconnaissance by stream sediments and panned concentrates was undertaken over an area of 850 km 2 of south-west Scotland. Rocks of Ordovician to Permian age are exposed within the area but the major part is occupied by the ...

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]
The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone

Data on Pre-Permian rocks are reported only from the P-1 well, which was bottomed in Caledonian basement. The geology of this formation in the western part of the Danish sector is, therefore, poorly known. According to the age determinations performed and reviewed by Frost et al. (1981), the North GermanPolish Caledonides extend under most of the North

Seismogeological structure model of the Anabar-Olenek region
The velocity characteristics of the Upper Proterozoic-Phanerozoic sedimentary cover of the AnabarOlenek region were studied, in particular, the bimodal character of the distribution interval P-wave velocities was established.

Late Paleozoic plutons are widely distributed in the Alxa region, southernmost Central Asian Orogenic Belt, and provided an important clue in constraint for the closing time of the Paleo-Asian Ocean (PAO). In this article, we present new zircon U-Pb ages
