On the feasibility of Paleomagnetic Euler Pole Analysis

Autor: Leandro C. Gallo, Mathew Domeier, Facundo Sapienza

Owing to the inherent axial symmetry of the Earth’s magnetic field, paleomagnetic data only directly record the latitudinal and azimuthal positions of crustal blocks in the past, and paleolongitude cannot be constrained. An ability to overcome this

The last few years have been marked by a number of motivating novel ideas and methodological advancements in paleomagnetic analysis (e.g. trans-hierarchical uncertainty propagation), observational and theoretical geodynamics, and paleogeographical mo

The James Ross Basin, in the northern Antarctic Peninsula, exposes which is probably the world thickest and most complete Late Cretaceous sedimentary succession of southern high latitudes. Despite its very good exposures and varied and abundant fossi

New paleomagnetic and anisotropy of magnetic susceptibility (AMS) studies were performed in the southern Subandes of Bolivia in order to assess vertical axis rotations in a poorly studied area. Due to the presence of polarity reversals, it was possib

A pure dipole analysis of the Gondwana apparent polar wander path: Paleogeographic implications in the evolution of Pangea

Autor: Renata Nela Tomezzoli, Ernesto Osvaldo Cristallini, Leandro C. Gallo

Publikováno v: Geochemistry, Geophysics, Geosystems. 18:1499-1519

The paleogeography of prebreakup Pangea at the beginning of the Atlantic Spreading has been a subject of debate for the past 50 years. Reconciling this debate involves theoretical corrections that cast doubt on available data and paleomagnetism as an

A long-standing debate regarding the configuration of Pangea during the Late Paleozoic has been going on among the paleomagnetic community concerning the validity of one of two significantly different Pangea reconstructions (Pangea A vs Pangea B) sin

Publikováno v: Journal of South American Earth Sciences. 107:103144

Anisotropy of magnetic susceptibility (AMS) has been used as an important tool to study magnetic fabrics and as a basis of interpretation of depositional conditions and post-depositional processes in sedimentary successions. This contribution present

Sedimentary evolution of a Permo-Carboniferous succession in southern Bolivia: Responses to icehouse-greenhouse transition from a probabilistic assessment of paleolatitudes

Publikováno v: Journal of South American Earth Sciences. 106:102923

The Permo-Carboniferous encompasses the deterioration of the Late Paleozoic Ice Age (LPIA), one of the most important glacial events in Earth's history. However, the key drivers behind the demise of the ice sheets remain controversial. Recent advance
