The North Atlantic Igneous Province (NAIP) has been the focus of numerous studies. However, a systematic integrated methodology to assess NAIP, so far lacking. For this purpose, synclinal oceanic rift approach is developed from stratigraphic record. Mechanisms are addressed combining trace element and seismic velocity data as proxy for excess mantle potential temperature (ΔTp), using simple mel...

Abstract The Olds Ferry terrane is the more inboard of two accreted volcanic arc terranes in late Paleozoic–early Mesozoic Blue Mountains province northern U.S. Cordillera. We present geologic, geochronologic, and geochemical data from volcano-sedimentary Huntington Formation that place within a firm temporal tectonomagmatic context, establish its identity as fringing along Triassic to Early Ju...

Abstract Results from the Sample Analysis at Mars‐evolved gas analyzer on board Mars Science Laboratory Curiosity rover constrained alteration history and habitability potential of rocks sampled across Siccar Point unconformity in Gale crater. The Glasgow member (Gm) mudstone just below had evidence acid sulfate or Si‐poor brine Fe‐smectite to Fe amorphous phases, leaching loss Fe‐Mg‐sulfate ex...

The Pyrenees are the result of structural inversion a rift general direction N110E, established at articulation European and Iberian plates. This was created by left-lateral transtension with severe crustal thinning during latest Early Cretaceous Mid-Cretaceous. Its inversion, which led to uplifting Pyrenean chain, took place gradually, transpression from east west, Late followed an Eocene coll...

The Proterozoic Athabasca Basin hosts a large number of high-grade, large-tonnage unconformity-related uranium (U) deposits, many which are also enriched in rare earth elements (REE). basin contains hydrothermal REE mineralization unassociated with U. Previous studies postulated that U and were derived from either the or basement; however, exact source metals remains ambiguous. This study provi...

Abstract New lithologic and detrital zircon (DZ) U-Pb data from Devonian–Triassic strata on St. Lawrence Island in the Bering Sea western Brooks Range of Alaska suggest affinities between these two areas. The constitutes part Arctic Alaska–Chukotka microplate, but tectonic paleogeographic are unknown or at best speculative. Strata form a carbonate succession Mississippian(?)–Triassic clastic th...
