Comparison of Evolution of Trioctahedral Chlorite/Berthierine/Smectite in Coeval Metabasites and Metapelites from Diagenetic to Epizonal Grades
AEM Berthierine Bukk Mountains Chlorite Low-grade Metamorphism Reaction Progress Smectite TEM XRD
2011/12/5
Abstract: The evolution of texture, structure and chemical composition of chloritic clays in coeval pairs of metabasites and metapelites of a prograde sequence from the Bükk Mountains has been investi...
An Fe-Berthierine from a Cretaceous Laterite: Part II. Estimation Of Eh, pH and pCO2 Conditions of Formation
Berthierine Gibbsite Goethite Cretaceous Kaolinite pCO2 pH Siderite Soil Zone Weathering
2011/12/22
Abstract: Transgression by the Western Interior Sea during the Late Cretaceous in southwestern Minnesota caused swampy conditions to be imposed upon a laterite consisting of gibbsite, goethite and kao...
An Fe-Berthierine from a Cretaceous Laterite: Part I. Characterization
Berthierine Cretaceous Weathering Kaolinite Minnesota Pisoid
2011/12/22
Abstract: An Fe-berthierine occurs in a buried laterite from the Late Cretaceous (Cenomanian) in southwestern Minnesota. It formed beneath a lignitic horizon in which reducing solutions percolated thr...
Berthierine from the Lower Cretaceous Clearwater Formation, Alberta, Canada
Berthierine Chamosite Diagenesis Neoformation Odinite Oil Sands
2011/12/1
Abstract: Berthierine occurs as pore-linings of well crystallized laths of variable thickness in oil-sands of the Clearwater Formation, Alberta, Canada. Berthierine crystallized early in diagenesis wi...
Microstructures, Mixed Layering, and Polymorphism of Chlorite and Retrograde Berthierine in the Kidd Creek Massive Sulfide Deposit, Ontario
Berthierine Chlorite Massive sulfide deposit Microstructures Mixed layering Polymorphism Polytypism Transmission electron microscopy
2011/12/31
Transmission electron microscopy (TEM) was utilized to determine the origins of berthierine and chlorite in the core of the footwall alteration zone of the Kidd Creek massive sulfide deposit, Ontario....
To test the hypothesis that berthierine in oolitic ironstones formed by diagenetic transformation of detrital kaolinite, laboratory experiments simulating the early diagenetic conditions were conducte...
Berthierine and Chamosite in Coal Measures of Japan
Berthierine Chamosite Coal Genesis Iron Siderite
2012/2/7
Berthierine (formerly chamosite) occurs as concretions, lenses, and bands in carbonaceous, kaolinitic shale of freshwater coal-swamp deposits in Paleogene and Upper Triassic coal measures of Japan. Te...
