Collisional Reactivation of Rift Margin Fracture Zones, Taiwan and the Taconic Allochthon
… and Stretching Lineation Orientation in the Taconic Allochthon, Vermont and New York</strong></p> <p><strong><em>Abstract —</em></strong> New and previously collected structural data were compiled to produce detailed maps of slaty cleavage (S<sub>2</sub>) and stretching lineation …

Major element and isotopic studies on the James Run/Port Deposit association, Maryland: tectonic analogues and Taconic deformation
… Deposit is interpreted as representative of the Taconic orogeny for the central Appalachian Piedmont; Rb-Sr whole rock systematics were upset, but concurrent anatexis of felsic basement is not locally evident. The fault contact between the Port Deposit and easternmost facies of the Wissahickon …

Allostratigraphy of the Upper Ordovician Blue Mountain Formation, Southwestern Ontario, Canada
… the distal response to the development of the Taconic Appalachian foreland basin. The proximal representation in Ohio and Pennsylvania, contain the Utica/Point Pleasant Play (!). The relationship between the proximal and distal portions of the Taconic Appalachian foreland basin is not clearly …

Tectonic and geologic development of the Charlotte belt south central Virginia Piedmont
… during the Late Cambrian to Late Ordovician Taconic orogeny. Both belts consist primarily of volcanic rocks, the major difference being that the Charlotte belt is amphibolite grade gneisses, whereas the slate belt is at greenschist grade. The major results of the study are as follows: (1) The …

Stratigraphy and Tectonics: Multi-Disciplinary Evaluation of Tectonic Models For the Eastern and Southern Continental Margins of North America
… that maximum subsidence rates during the Taconic phase were ~1.5 times faster than those of the subsequent Acadian phase. Subsidence rates during the Alleghanian phase were much slower than the preceding Taconic and Acadian phase. The decrease of subsidence rates from the oldest to the …

Geology of the Meherrin, Virginia area: tracing formations across the staurolite isograd from the Carolina slate belt into the Charlotte belt
… attribute late folding and metamorphism to the Taconic orogeny. F₁ is attributed to the Virgilina deformation. F₂ and F₃ are attributed to the Taconic and/or Acadian orogenies.

Ο ρόλος των μηχανοϋποδοχέων στη μη-αλκοολική στεατοηπατίτιδα
… με Western diet - CCl₄ και το διατροφικό μοντέλο Taconic. Πραγματοποιήθηκε ανάλυση γονιδιακής έκφρασης σε επιλεγμένα χρονικά σημεία και στατιστική αξιολόγηση των συσχετίσεων μεταξύ Piezo1 και χαρακτηριστικών μοριακών δεικτών. Και στα δύο μοντέλα παρατηρήθηκε συνολική τάση αύξησης της έκφρασης του …

Contributions of type 17 immunity and type I interferon signaling to Salmonella-induced autoimmunity
… inflammation by using C57BL/6 mice from Taconic Farms and Jackson Laboratory, which, due to microbiota differences, have different basal levels of IL-17. When mice were intraperitoneally (i.p.) injected with curli/DNA complexes, we observed no difference in the production of anti-dsDNA …

EMPLACEMENT OF THE DADEVILLE COMPLEX OF THE SOUTHERNMOST INNER PIEDMONT WITHIN THE 7.5 MIN. CUSSETA QUADRANGLE, CHAMBERS COUNTY, ALABAMA: CHANNEL FLOW, KLIPPE KINEMATICS, OR OROGEN PARALLEL TRANSLATION
… history spanning three orogenic periods, the Taconic, the Acadian/Neoacadian, and Alleghanian orogenies. The Inner Piedmont of the Appalachian Mountains within Alabama contains two distinct lithologic complexes, the Dadeville Complex, and the Opelika Complex separated by the Stonewall Line. …

Geology of the Roberts Hill area in the Hudson Valley fold-thrust belt, Greene County, eastern New York
… detachment, crops out at or just above the post-Taconic unconformity and forms the floor thrust of a distinct duplex. The lower fault called the Austin Glen detachment, does not crop out but has been inferred to occur at a depth of several hundred meters below the surface. Mapping of a 5 km-long …

High Resolution Stratigraphy of Ordovician Carbonates, Kentucky: Evidence for a Greenhouse to Glacial Transition
… uplift of the subducting margin at the onset of Taconic orogenesis. Middle Ordovician carbonates were deposited on a ramp peripheral to a foredeep in Tennessee. The Middle Ordovician High Bridge Group consists of a 2nd-order supersequence with three 3rd-order sequences (each 30 to 100 m thick), …

Paleoenvironmental Reconstruction of an Upper Ordovician Rocky Shoreline: The Lindsay Formation of Heywood and Partridge Islands, Ontario
… mountain building processes associated with the Taconic Orogeny were taking place to the present east, and the tectonic effects of this orogeny resulted in subsidence of the Michigan Basin. The Lindsay Formation of the Trenton Group was deposited in this basin during a prolonged period of low …

Correlation of seismic reflection data with seismicity over the Ramapo, New Jersey, fault zone
… zones. The seismic line furthest from the Taconic suture displays fewer hypocenters and mylonites, in agreement with an assumed model of mylonite development possibly associated with obduction of continental crust. The mylonite zones in the basement may serve as local areas of crustal …

Lithologic, edaphic, and biotic factors of small mammal habitats in the slate belt of Western Rutland County, Vermont, and Eastern Washington County, New York
… <p>The bedrock of the region is part of the Taconic sequence of rocks, and is primarily slate and phyllite that ranges in age from Early Cambrian to Middle Ordovician. The lithology of the Taconic bedrock is largely responsible for the type of soil development in the slate belt. Shallow soils …

Ultramafic Alteration and the Cooling of Earth and Mars
… of ultramafic and mafic rocks across the Taconic orogeny in Newfoundland, Canada. This collision exposed one of the most well-studied ultramafic bodies on Earth, the Bay of Islands ophiolite, and closely preceded global cooling in the Middle-Late Ordovician (470-445 Ma). I present a new …

An unconformity in the Carolina slate belt of central North Carolina: new evidence for the areal extent of the ca. 600 Ma Virgilina deformation
… folded (F₂) and metamorphosed during the Taconic deformation (D₂). Associated with the Taconic event is the development of a pervasive spaced anastomosing cleavage (S₂) in the volcanic lithologies. Previous regional correlations preferred by Wright and Seiders (1980) are thought to be …
