The injection of I-type granitoid bodies (Hosh intrusion) with calc-alkaline affinity into Lower Cretaceous limestones (Taft Formation) has produced the various types of related skarns and marbles. Thereby, those skarns formed can be undoubtedly divided into four groups, clinopyroxene-plagioclase skarns, clinopyroxene skarns, clinopyroxene- vesuvianite skarns and moreover garnet skarns. Additio...
متن کاملGarnet-fassaite calc-silicate nodule from La soufriire. st. vincent
The mineralogy of an unusual calc-silicate nodule brought to the surfaoe by the 1902 eruption of La Soufriere volcano on St. Vincent (Lesser Antilles arc) is described. It consists of the crystalloblastic mineral assemblage fassaite pyroxene + grandite garnet + wollastonite + anorthite t calcite. The pyroxene is more aluminous (Al2O3 : 19.66 weight percent) than any previously described from te...
متن کاملTrace element partitioning between wollastonite and silicate-carbonate melt
We have performed an experimental study of the influence of varying size and charge on cation partitioning between wollastonite and silicate-carbonate melt in the system CaCO3-SiO2. The experimental conditions (3 GPa, 14208C) lie close to the wollastonite II tc/I tc phase boundary. Results for 1+, 2+, 3+ and 4+ partitioning show parabolic dependence of partition coefficients on ionic radius, wh...
متن کاملکانیشناسی و سنگ‌شناسی زینولیتهای کالک- سیلیکاته
The calc-silicate xenoliths, within the Shir-Kuh batholith are characterized by melilite, garnet, vesuvianite, and wollastonite mineral assemblage. On the basis of paragenetic relations, prograde and retrograde metamorphism are involved in the formation of these minerals. Melilite, wollastonite and diopside formed during progressive metamorphism which was accompanied by thermal peak shocking a...

Tang-e-Hana skarn is located at part of the Zagros ophiolitic sequence, and then it is considered as a part of the Zagros structural province. According to the current study, this skarn is classified in 4 main groups: 1- Wollastonite skarn 2- Augite wollastonite skarn 3- Grossular wollastonite skarn 4- Andradite titanite augite wollastonite skarn. Geochemical characteristics indicate that Tang-...
