Authigenic or detrital origin of pyrrhotite in sediments?: Resolving a paleomagnetic conundrum

Horng, Chorng-ShernRoberts, Andrew2015-12-070012-821Xhttp://hdl.handle.net/1885/22568Monoclinic pyrrhotite (Fe7S8) is widely claimed to carry magnetizations acquired during early diagenesis in anoxic sedimentary environments. In contrast, geochemical literature indicates that pyrrhotite formation is extremely slow below 180 °C, which makKeywords: Authigenic; Diagenesis; Iron sulphide; Monoclinic; Pyrrhotite; Geochemistry; Magnetization; Metamorphic rocks; Remanence; Sediments; Sulfide minerals; paleomagnetism; pyrrhotite; sediment chemistry Authigenic; Detrital; Diagenesis; Hexagonal; Iron sulphide; Monoclinic; PyrrhotiteAuthigenic or detrital origin of pyrrhotite in sediments?: Resolving a paleomagnetic conundrum200610.1016/j.epsl.2005.11.0082015-12-07
