Changes in Coral Skeleton Growth Recorded by Density Band Stratigraphy, Crystalline Structure, and Hiatuses

Autor: Kyle W. Fouke, Jeffrey M. Trop, Mayandi Sivaguru

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Next-generation high resolution brightfield microscopy, x-radiography, and microcomputed tomography (microCT) analyses indicate that coral skeleton high density band (HDB) and low density band (LDB) stratigraphic sequences record dynamic changes in c

Geochronology of the Wrangell Arc: Spatial-temporal evolution of slab-edge magmatism along a flat-slab, subduction-transform transition, Alaska-Yukon

Autor: Jeffrey M. Trop, Jeff A. Benowitz, Carl S. Kirby, Matthew E. Brueseke

Publikováno v: Geosphere. 18:19-48

The Wrangell Arc in Alaska (USA) and adjacent volcanic fields in the Yukon provide a long-term record of interrelations between flat-slab subduction of the Yakutat microplate, strike-slip translation along the Denali–Totschunda–Duke River fault s

VERTEBRATE TAPHONOMY, PALEONTOLOGY, SEDIMENTOLOGY, AND PALYNOLOGY OF A FOSSILIFEROUS LATE DEVONIAN FLUVIAL SUCCESSION, CATSKILL FORMATION, NORTH-CENTRAL PENNSYLVANIA, USA

Autor: Edward B. Daeschler, Pierre A. Zippi, Matthew B. Vrazo, Michael C. Rygel, Jeffrey M. Trop, David Broussard, Cayla Treaster

Publikováno v: PALAIOS. 35:470-494

The fluvial facies of the Catskill Formation record important ecological events that occurred during Late Devonian time. A well-exposed section between the towns of Blossburg and Covington, in north-central Pennsylvania, contains abundant macrofossil

Detrital zircon geochronology and Hf isotope geochemistry of Mesozoic sedimentary basins in south-central Alaska: Insights into regional sediment transport, basin development, and tectonics along the NW Cordilleran margin

Autor: Cooper R. Fasulo, Jeffrey M. Trop, Kenneth D. Ridgway

Publikováno v: Geosphere. 16:1125-1152

The Jurassic–Cretaceous Nutzotin, Wrangell Mountains, and Wellesly basins provide an archive of subduction and collisional processes along the southern Alaska convergent margin. This study presents U-Pb ages from each of the three basins, and Hf is

Stitch in the ditch: Nutzotin Mountains (Alaska) fluvial strata and a dike record ca. 117–114 Ma accretion of Wrangellia with western North America and initiation of the Totschunda fault

Autor: Donald Q. Koepp, David Sunderlin, Matthew E. Brueseke, Jeffrey M. Trop, Paul G. Fitzgerald, Paul W. Layer, Jeffrey A. Benowitz

Publikováno v: Geosphere. 16:82-110

The Nutzotin basin of eastern Alaska consists of Upper Jurassic through Lower Cretaceous siliciclastic sedimentary and volcanic rocks that depositionally overlie the inboard margin of Wrangellia, an accreted oceanic plateau. We present igneous geochr

SEDIMENTOLOGY AND CARBON ISOTOPE (δ13C) STRATIGRAPHY OF SILURIAN–DEVONIAN BOUNDARY INTERVAL STRATA, APPALACHIAN BASIN (PENNSYLVANIA, USA)

Autor: Jeffrey M. Trop, Anya V. Hess

Publikováno v: PALAIOS. 34:405-423

Silurian–Devonian boundary interval strata deposited during the expansion of land plants record a major perturbation of the carbon cycle, the global Klonk Event, one of the largest carbon isotope excursions during the Phanerozoic. In the Appalachia

Cenozoic tectono-thermal history of the southern Talkeetna Mountains, Alaska: Insights into a potentially alternating convergent and transform plate margin

Autor: Jeffrey M. Trop, Jeffrey A. Benowitz, Robert J. Gillis, Jeffrey T. Freymueller, Paul B. O'Sullivan, Patrick Terhune

Publikováno v: Geosphere. 15:1539-1576

The Mesozoic–Cenozoic convergent margin history of southern Alaska has been dominated by arc magmatism, terrane accretion, strike-slip fault systems, and possible spreading-ridge subduction. We apply 40Ar/39Ar, apatite fission-track (AFT), and apat

Cretaceous to Miocene magmatism, sedimentation, and exhumation within the Alaska Range suture zone: A polyphase reactivated terrane boundary

Autor: Jeffrey A. Benowitz, Ronald B. Cole, Paul B. O'Sullivan, Jeffrey M. Trop

Publikováno v: Geosphere. 15:1066-1101

The Alaska Range suture zone exposes Cretaceous to Quaternary marine and nonmarine sedimentary and volcanic rocks sandwiched between oceanic rocks of the accreted Wrangellia composite terrane to the south and older continental terranes to the north.
