1 de mar. de 2020 · Two types of magnetite, i.e., mushketovite (T M1) and granular (T M2) magnetite, are identified based on their morphology. Mushketovite shows three different zones (central bright, dark, and outer bright) in backscattered electron (BSE) images.

12 de jun. de 2019 · Transition to (pseudo)mushketovite. In contrast to martitisation, the transition from overprinted, Si-magnetite to (pseudo)mushketovite is defined by a continuum of textural aspects from granular to bladed, acicular, feathery or fibrous magnetite (Fig. 9).
2001), usually replaced by magnetite (mushketovite). In Tropezón, the amount of mushketovite is accessory and most of the magnetite occurs in anhedral to subhedral grains. Hematite occurs in late veins or replacing earlier magnetite. Anhydrite, bassanite, and scapolite occur as irregularly distributed patches. The innermost alteration zone ...
2 de sept. de 2023 · We compare various magnetite- (apatite) systems worldwide, with emphasis on the subvolcanic rocks of El Laco, Chile. We contend that the formation of magnetite- (apatite) systems can only be explained by the crystallization of highly evolved, Si-Al-poor (ultrabasic) iron-rich melts.
1 de jul. de 2005 · Mushketovite is a pseudomorphic replacement of specularite by magnetite that forms under reducing conditions commonly below the hematite-magnetite buffer (Ohmoto, 2003; Mucke and Cabral, 2005 ...
