Mineralogy of Dickite and Nacrite from Northern Taiwan
Alteration Dickite Hydrothermal Nacrite Taiwan
2011/12/5
Abstract: Nacrite and dickite are found in two localities in northern Taiwan. One, containing nacrite and dickite, is associated with a gold-enargite deposit as a vug-filling clay in the Chinkushih (C...
Dickite, Nacrite and Possible Dickite/Nacrite Mixed-Layers from the Betic Cordilleras (Spain)
Dickite Differential thermal analysis Infrared spectroscopy Mixed-layers Nacrite Very low-grade metamorphism X-ray powder diffraction
2011/12/23
Abstract: Nacrite, dickite and intermediate dickite-nacrite phases have been identified from the upper Paleozoic sequences of the Malúguide Complex (Betic Cordilleras, Spain). Nacrite developed as euh...

Abstract: Nacrite crystals from a vug within a matrix of dickite at Red Mountain near Silverton, Colorado, have a = 8.906(2), b = 5.146(1), c = 15.664(3) Å, β = 113.58(3)°, V = 657.9(3) Å3...
Infrared Study of Structural OH in Kaolinite, Dickite, Nacrite, and Poorly Crystalline Kaolinite at 5 to 600 K
Crystallinity Dickite Infrared spectroscopy Kaolinite Nacrite X-ray powder diffraction
2012/1/6
The resolution of the infrared spectra of structural OH in kaolin-group minerals increases with decreasing temperature. Poorly crystalline kaolinite gives typical infrared spectra, which suggest the e...
An Occurrence of Authigenic Nacrite
Authigenesis Kaolin-group mineral Nacrite Pore solution Shale
2012/1/9
Euhedral, pseudohexagonal nacrite was discovered as a thin layer coating a carbonaceous shale in the Sherwood Tunnel in Durban, Republic of South Africa. The nacrite apparently formed authigenically w...
Interlayer Bonding in Kaolinite, Dickite and Nacrite
Interlayer Bonding Kaolinite Dickite Nacrite
2012/2/15
A simple electrostatic model has been used to demonstrate that the inner surface hydroxyls in kaolinite, dickite and nacrite are responsible for the interlayer bonding in these minerals. The contribut...
