TLDR
Petrographic, rock magnetic and electron microprobe investigations confirm that nearly pure hematite is the essential magnetic phase (up to about 10 vol. %) occurring as a replacement of coarse fitaniferous magnetite phenocrysts and fine groundmass particles, as a secondary alteration product of ferromagnesian phenocryst and as a mobilized phase filling cracks and other open spaces as discussed by the authors.About:

Late Triassic paleolatitude of the Qiangtang block: Implications for the closure of the Paleo-Tethys Ocean
Peiping Song,Lin Ding,Zhenyu Li,Peter C. Lippert,Peter C. Lippert,Tianshui Yang,Xixi Zhao,Xixi Zhao,Jiajun Fu,Yahui Yue +9 more
TL;DR: In this article, a combined paleomagnetic and zircon U/Pb geochronological study has been conducted on the Upper Triassic Jiapila Formation volcanic rocks on the northern edge of the Qiangtang block of Central Tibet (34.1°N, 92.4°E).

West African proximity of the Avalon terrane in the latest Precambrian
TL;DR: In this article, the authors used the results from upper Neoproterozoic rocks in the Avalon terrane to challenge the latter position and revealed that the paleolatitude of Avalon is significantly lower than would be expected if it was part of Amazonia.
Journal ArticleDOI
Differential rotation of the eastern part of southwest Japan inferred from paleomagnetism of Cretaceous and Neogene rocks
TL;DR: Paleomagnetic directions have been determined on Late Cretaceous and Miocene rocks in the Nohi area, in the eastern part of southwest Japan, in an effort to clarify within-block deformation of the rotated part of Japan.
Journal ArticleDOI
An early bird from gondwana: paleomagnetism of lower permian lavas from northern qiangtang (tibet) and the geography of the paleo-tethys
TL;DR: In this article, the authors provided a robust and well-dated paleomagnetic pole from the Lower Permian Kaixinling Group lavas on the northern Qiangtang block.
Journal ArticleDOI
Single-domain chemical, thermochemical and thermal remanences in a basaltic rock
TL;DR: In this paper, isothermal chemical remanence (CRM) and TCRM were acquired under various conditions and subjected to Thellier-type experiments, and the CRM/TRM ratio was found to be less than one and increases rapidly with acquisition temperature (0.35 at 400 C, 0.65 at 450 C and 0.90 at 500 C).

The physical principles of rock magnetism
TL;DR: A review of the physical principles of rock magnetism can be found in this article, which is of modest length and meets the dual requirements of being comprehensible to geologists and satisfying to physicists Even a very small percentage of a ferromagnetic mineral, such as magnetite, in a rock masks the paramagnetic and diamagnetic properties of the other minerais.

Magnetic properties and oxidation of iron‐titanium oxide minerals in Alae and Makaopuhi Lava Lakes, Hawaii
TL;DR: In this paper, the authors show that the transition from medium to high Curie temperatures occurs between 850° and 300°C, varying from one drill hole to another, and is accompanied by a marked increase in the strong field magnetization at room temperature.
