Corrensite – WGNHS – UW–Madison
Corrensite is a mineral formed from regular interlayers of chlorite with either vermiculite or smectite. It forms during low grade or hydrothermal metamorphism of basaltic rocks.
Polymorphism & Series: A 1:1 mixed-layer interstrati ̄cation of trioctahedral chlorite with either a trioctahedral vermiculite or a trioctahedral smectite. Occurrence: From diverse sedimentary environments, which produced clastic, carbonate, volcanoclastic, or evaporite rocks.
Corrensite and mixed-layer chlorite/corrensite in metabasalt from ...
The chloritic minerals include corrensite, which is an ordered 1:1 mixed-layer chlorite/smectite, and “expandable chlorite”, which is shown to be a mixed-layer chlorite/corrensite. Corrensite and some mixed-layer chlorite/corrensite occur as rims of vesicles and other cavities, while later-formed mixed-layer chlorite/corrensite occupies the ...
Corrensite and associated smectites in the Teschenite Association …
2023年10月1日 · Corrensite is the strongly predominant component of the clay fractions in the redeposited hyalotuffs. They have a macroscopic appearance of a crumbling, soft brownish sandstone. Corrensite was commonly present as a component of fine-grained, green, distinctly strongly altered effusive rocks in the outcrops along the Morávka channel.
Corrensite
Corrensite, Mordenite, Quartz (Var: Chalcedony) Dillon area, Beaverhead Co., Montana, USA. Specimen of mordenite with chalcedony from amygdaloids in tuffaceous rocks of Volcanic Series II about 9 miles south of Dillon on Interstate 15. Heulandite forms the shell of many amygdaloids but is not notable in this specimen.
Crystal Chemistry of Corrensite: A Review | Clays and Clay Minerals
Thus, the current definition of corrensite as a regular 1:1 interstratification of trioctahedral chlorite and either trioctahedral smectite or vermiculite is appropriate. Statistical analyses of chemical data from the literature of corrensite minerals suggest a large compositional variability, more evident in octahedral than
Corrensite; A single phase or a mixed-layer phyllosilicate in …
1997年2月1日 · Corrensite should not be regarded as a regular, 50:50 mixture of chlorite and smectite mixed layers but as a true phase in the thermodynamic sense with a discrete stability field and paragenetic relationships with saponite and chlorite.
Mineral Database - Mineralogy of Wales - Museum Wales
corrensite is a clay mineral consisting of regular interstratifications of trioctahedral chlorite and trioctahedral smectite in equal proportions. It most typically develops as an authigenic mineral (one that forms after deposition) in sedimentary rocks such as mudstone and shales, or as an alteration product in hydrothermally altered rocks ...
