Mesozoic–Cenozoic stress field magnitude in Sichuan Basin, China and its adjacent areas and the implication on shale gas reservoir: Determination by acoustic emission in rocks

open access: yesChina Geology, 2020
: The Sichuan Basin is one of the vital basins in China, boasting abundant hydrocarbon reservoirs. To clarify the intensity of the tectonic stress field of different tectonic episodes since the Mesozoic and to identify the regional dynamic background of ...

Paleomagnetic Study of Mesozoic Continental Sediments Along the Northern Tien Shan (China) and Heterogeneous Strain in Central Asia [PDF]

open access: yes, 1991
A paleomagnetic study of rocks from the northern foot of the Tien Shan and the southern border of the Dzungar Basin, east of Urumqi (44.2°N, 86.0°E), spanning ages from middle Jurassic to early Tertiary was carried out to constrain the tectonic evolution

High-Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]

open access: yes, 2020
Archeomagnetism focuses on exploring high-resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site

Role of Paleomagnetism in the Construction of Earth’s Geographic Past

open access: yesUndergraduate Journal of Mathematical Modeling: One + Two, 2020
Rocks have the ability to preserve magnetic information used in determining past geographic formations. The purpose of this report is to determine the past location of a site from a given data set’s magnetic information and the calculations found through

Rapid, Precise, and High-Sensitivity Acquisition of Paleomagnetic and Rock-Magnetic Data: Development of a Low-Noise Automatic Sample Changing System for Superconducting Rock Magnetometers [PDF]

open access: yes, 2008
Among Earth sciences, paleomagnetism is particularly linked to the statistics of large sample sets as a matter of historical development and logistical necessity.

New data concerning the early middle miocene on the southern slopes of Fruška Gora (Northern Serbia): A case study from the Mutalj quarry [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2011
During the last few years, geological research at the southern slopes of Fruška Gora Mt. enabled the discovery of different Miocene units (undivided the Lower Miocene and Middle Miocene Badenian, predominantly). This is primarily thinking of the

A strong angular dependence of magnetic properties of magnetosome chains: Implications for rock magnetism and paleomagnetism

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Single‐domain magnetite particles produced by magnetotactic bacteria (magnetosomes) and aligned in chains are of great interest in the biosciences and geosciences. Here, we investigated angular variation of magnetic properties of aligned Magnetospirillum

Paleomagnetism of Upper Vendian sediments from the Winter Coast, White Sea region, Russia: Implications for the paleogeography of Baltica during Neoproterozoic times [PDF]

open access: yes, 2002
Paleomagnetic results from an Upper Vendian sedimentary sequence exposed along the White Sea shoreline, NW Russia are described. These classical exposures have been the subject of intense paleontological investigations due to their well-preserved ...

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.
