Phanerozoic polar wander, palaeogeography and dynamics
Abstract A significant number of new palaeomagnetic poles have become available since the last time a compilation was made (assembled in 2005, published in 2008) to indicate to us that a new andExpand
Opening Iapetus: Constraints from the Laurentian margin in Newfoundland
Late Neoproterozoic to Early Cambrian geologic, geochronologic, and paleomagnetic data from along the Iapetus margin of Laurentia may be reconciled within a multistage rift history that involved anExpand
The fall, recovery, orbit, and composition of the Tagish Lake meteorite: a new type of carbonaceous chondrite.
TLDR
The mineralogy, oxygen isotope, and bulk chemical composition of recovered samples of the Tagish Lake meteorite are intermediate between CM and CI meteorites, suggesting that the Tagishes Lake meteoroid may be one of the most primitive solar system materials yet studied. Expand
The role of the Kazakhstan orocline in the late Paleozoic amalgamation of Eurasia
ARTICLE I NFO The Kazakhstan orocline, a horseshoe-shaped belt with volcanic arcs of Devonian (external) and late Paleozoic (internal) age, is thought to have formed as a result of convergenceExpand
Circum-Iapetus paleogeography of the Precambrian-Cambrian transition with a new paleomagnetic constraint from Laurentia
Abstract The paleogeography of the Precambrian–Cambrian transition is still poorly known, but is fundamental for understanding Late Neoproterozoic climate extremes and the spatial associations of theExpand
Unraveling the early–middle Paleozoic paleogeography of Kazakhstan on the basis of Ordovician and Devonian paleomagnetic results
Abstract It is a common concept that different tectonic units in the western part of the Central Asian Orogenic Belt were united into the landmass of the Kazakhstania continent in the Paleozoic butExpand
Precisely locating the Ordovician equator in Laurentia
The Late Ordovician equatorial zone, like the zone today, had few hurricane-grade storms within 10o of the equator, as emphasized by the preservation of massive-bedded Thalassinoides ichnofaciesExpand
Paleomagnetic study of the late Neoproterozoic Bull Arm and Crown Hill formations (Musgravetown Group) of eastern Newfoundland: implications for Avalonia and West Gondwana paleogeography
A paleomagnetic study of subaerial volcanic rocks and associated siltstones of the Ediacaran Bull Arm Formation in the Avalon Zone of Newfoundland revealed a stable bipolar, hematite-borne primaryExpand
PALEOMAGNETISM OF THE 550 MA SKINNER COVE VOLCANICS OF WESTERN NEWFOUNDLAND AND THE OPENING OF THE IAPETUS OCEAN
The Skinner Cove Formation of western Newfoundland is an alkali volcanic suite transported in the Ordovician onto Laurentia's Iapetus Ocean margin. It has previously yielded a U–Pb zircon age ofExpand
