Abstract:
The Eagle Plutonic Complex is an elongate north-northwest-trending body of deformed Middle to Late Jurassic and middle Cretaceous rocks which underlies the southwestern margin of the Intermontane terrane. New mapping of the complex and its country rocks, in concert with geochronometry, has defined episodes of contractional, ductile deformation in the Middle to Late Jurassic and middle Cretaceous, as well as brittle deformation in Tertiary time. Synkinematic Middle to Late Jurassic Eagle tonalite at the eastern margin of the Eagle Complex intrudes mylonitic Nicola Group rocks and structurally o

ABSTRACT A regional structure contour map at Near Top Cretaceous is based on hundreds of well tops from extensive bibliographic references from throughout the Middle East. This structure map shows strong basin asymmetry. Major faults are shown in outcrop and/or suspected at basement or intermediate levels, based in part on gravity and magnetics modeling, published and in ‘open file’ studies. Major uplifts associated with several super-giant oil and gas fields are clearly indicated even at the shallow Cretaceous level (Ghawar Anticline, Qatar Arch, Burgan-Khurais Trend, etc.), even at a very re

Abstract:
Late Mesozoic magmatism in Southeast China extensively reworked the Cathaysia Block’s crust, linked to the Paleo-Pacific Plate subduction beneath East Asia. The northeastern Cathaysia Block, largely covered by Cretaceous volcanic-sedimentary basins, has limited Jurassic exposure to Early Cretaceous intrusions, which provides critical insights into deep crust-mantle processes. In this study, we present zircon U-Pb geochronology and Hf isotope, whole-rock geochemistry, and Sr-Nd isotopes of the Middle Jurassic syenite-granite suites and Early Cretaceous granites with enclaves in the Qingyuan are

AbstractThis study is focused on slide blocks including oceanic lavas associated with pelagic sediments within the eastern part of the Ankara Mélange. A detailed petrological characterization of the volcanic rocks and a detailed biochronological investigation of the associated radiolarian cherts in eight sections (east of Ankara) was carried out. The volcanic rocks are largely represented by basalts and minor ferrobasalts and trachytes.

The present research is on the Cretaceous microbio- and litho-stratigraphy of the Cauvery Basin, Southeast India. The planktonic and benthonic foraminifera are used to establish microbiostratigraphic zonations for the mid-Cretaceous succession in the Basin; leading to the first proposal of a benthonic foraminiferal zonation scheme. The schemes are primarily defined for regional application. In the absence of a formal lithostratigraphic classification for the Cretaceous succession in the Basin, a revised lithostratigraphy, in line with standard stratigraphic procedure, is proposed.

Early Cretaceous rifting resulted in accumulation of Alexis Formation basalt units and Bjarni Formation nonmarine and marginal marine clastic rocks. In the Late Cretaceous, extension focused further offshore as sag basin conditions formed across the shelf, with a basinwide transgression of Markland Formation shale and localized Freydis Memb

Abstract:
This report provides new rare earth element (REE) data from Permian through to Late Cretaceous sedimentary rocks of the Sverdrup Basin, along with focused analyses on phosphate nodules that occur in the Middle Triassic Murray Harbour Formation. Results show the overall sedimentary values are low, however phosphate nodules are highly enriched in REEs.

Abstract:
Sedimentary basins within the Labrador-Baffin Seaway are the product of rifting between Greenland and the paleo-North American Plate. Rifting started in the Early Cretaceous, with seafloor spreading initiated in the Paleocene and ending near the Eocene-Oligocene boundary. A change in the spreading direction in the latest Paleocene resulted in transform offsets in the Davis Strait and along fracture zones in Baffin Bay, with deformation in northern Baffin Bay during the Eurekan Orogeny. Since the stratigraphy of western Baffin Bay is poorly constrained, analogues are used from the well studied
