Inclusions in cassiterite and associated minerals

Economic Geology, 1960
A study was made of the inclusions in 133 specimens of cassiterite and associated minerals from world wide Sn deposits. From the distribution of inclusion types, it would appear that most pegmatitic Sn deposits have been formed from siliceous melts, but that most other types of deposits have been formed from aqueous solutions.

Fluid inclusions in fluorite mineralizations of northwestern Sicily, Italy

Chemical Geology, 1987
Abstract Several fluorite ± barite mineralizations, mainly controlled by post-Pliocene disjunctive faults, occur in silicified and altered Mesozoic limestones in the area of Termini Imerese (NW Sicily). In this study, we examined fluid inclusions in fluorite from the localities of Rocca Grande and Poggio Balate.

Introduction to Minerals, Inclusions and Volcanic Processes

Reviews in Mineralogy and Geochemistry, 2008
Minerals are intrinsically resistant to the processes that homogenize silicate liquids—their compositions thus yield an archive of volcanic and magmatic processes that are invisible at the whole rock scale. Minerals and their inclusions record diverse magma compositions, the depths and temperatures of magma storage, the nature of open system processes,

Impact of vitamin and mineral supplement withdrawal and wheat middling inclusion on finishing pig growth performance, fecal mineral concentration, carcass characteristics, and the nutrient content and oxidative stability of pork.

Journal of Animal Science, 2002
A study was conducted to determine if supplement withdrawal (omission of dietary vitamin and trace mineral premixes and a two-thirds reduction in dietary inorganic phosphorus) for 28 d preslaughter and the feeding of wheat middlings (dietary ...

Endogenous Mineralization, Inclusions, and Deposition Disorders

2008
The entities discussed in this chapter are diverse. Many come under the heading of metabolic diseases, which may be congenital or acquired. Others have, or act through, an immunologic basis. A few have a single identifiable cause. Some represent a common tissue response to multiple identified causes, while others appear to have no known causes.

Short-chain carboxylates in fluid inclusions in minerals

Applied Geochemistry, 2000
Abstract The carboxylate (formate, acetate, propionate and oxalate) and common inorganic anions (F − , Cl − and SO 2− 4 ) compositions for aqueous fluid inclusion leachates from 17 mineral samples collected from various deposits have been determined using ion chromatography in conjunction with microthermometric measurements on the fluid inclusions ...

Systematics of Fluid Inclusions in Diagenetic Minerals

1994
The past decade has revealed significant advantages to using fluid inclusions as a means of understanding the physical and chemical history of fluids in sedimentary basins, but it also has revealed important limitations which have required that a new approach must be employed to effectively use fluid inclusions. This book is divided into six sections: (

Rb-Sr dating of sphalerite based on fluid inclusion-host mineral isochrons; a clarification of why it works

, 1996
Nakai et al. (1990, 1993), Brannon et al. (1992), and Christensen et al. (1995a, b) recently published precise Rb-Sr formation ages of sphalerites from various Mississippi Valleytype deposits.

LIQUID INCLUSIONS IN MINERALS AS A GEOLOGIC BAROMETER

International Geology Review, 1960
The understanding and determination of pressures at the time of mineral formation is an important factor in the study of mineral-forming environments; environmental pressures are derived through investigation of physicochemical properties of gaseous-liquid inclusions.

Zinc Deposits and Related Mineralization of the Burketown Mineral Field, Including the World-Class Century Deposit, Northern Australia: Fluid Inclusion and Stable Isotope Evidence for Basin Fluid Sources

, 2006
The stratiform Century Zn-Pb deposit and the discordant Zn-Pb lode deposits of the Burketown mineral field, northern Australia, host ore and gangue minerals with primary fluid inclusions that have not been affected by the Isan orogeny, thus providing a ...
