metal sulfides nanoparticle size fractionation acid volatile sulfides Lake Teganuma
2017/4/10
Concentrations of acid volatile sulfides (AVS) as metal sulfides in three different size fractions (<30 nm, 30–200 nm,
>200 nm) at Lake Teganuma were measured using a nano-filtration followed by a pu...

The Formation of Sulfides during Alteration of Biotite to Chlorite-Corrensite?
TEM AEM Altered Biotite Biotite Chlorite Corrensite Hydrobiotite Pyrite Sphalerite
2011/12/8
Abstract: Transmission electron microscopy/analytical electron microscopy (TEM/AEM) were utilized to study pyrite and sphalerite inclusions in chlorite or mixed-layer chlorite-corrensite from an analc...
Iron sulfides from magnetotactic bacteria: Structure, composition, and phase transitions
Iron sulfides magnetotactic bacteria Structure composition phase transitions
2012/4/1
The top 20 cm of sediments at active cold seeps in Monterey Bay, coastal California,contain framboidal pyrite that occurs as infillings and pseudomorphs of the chambers of the tests of foraminifera an...
Genesis and Morphology of Iron Sulfides in Gray Kaolins
Kaolinite Marcasite Morphology Oxidation Pyrite Scanning electron microscopy Sulfide
2011/11/30
Abstract: Many of the presently oxidized Georgia kaolins probably existed originally in the reduced (gray) state. For that reason, the distribution of iron sulfides in presently gray kaolins may eluci...

Authigenic, well-crystallized kaolinite and dickite occur within sulfide mineral deposits (minesize to hand-specimen size occurrences) of the Mississippi Valley type in Arkansas, Kansas, Missouri, Iow...
VARIOUS ASPECTS OF ATOMIC DISPLACEMENTS IN METALLIC SULFIDES
ATOMIC DISPLACEMENTS METALLIC SULFIDES
2014/4/8
Movements of atoms can be observed and even brought about in metallic sulfides. A change in the structure may result from a large number of these movements. These displacements can be studied by vario...
