The long-standing controversy about the origin of magnetite-(apatite) mineral deposits pertains to how they form. Pleistocene El Laco deposit in northern Chile is a critical location because host andesite contains immiscible melt inclusions trapped plagioclase and clinopyroxene phenocrysts that reveal involvement melts evolution Volcanic System hosting mineralization. We present results from fi...

There are two kinds of chlorites occurred in Anshan area, among which the hydrothermal Fe-chlorite with longer Fe-OH wavelength is spatially related to high-grade magnetite ore, meaning that mapping can be used target BIF-hosted high grade iron ore. In this article, quadratic polynomial, cubic spline, and quartic polynomial method were interpolate absorption near 2250 nm China ZY1-02D satellite...

The Tonggou deposit is a porphyry Cu and vein-type Cu-Zn mineralization system located in the Bogda Orogenic Belt, north of Eastern Tianshan. Systematic fluid inclusion analyses were performed on granular quartz from magnetite–quartz stage pyrite–chalcopyrite–quartz mineralization. During early mineralization, ore-forming fluids at high temperatures (450–501 °C) salinity (51.2–55.2 wt.% NaCl eq...

nain ophiolite melange is located 140 km east of isfahan. based on the geological studies, this area belongs to mesozoic ophiolite of urumieh – dokhtar zone, west of central iran. country rocks are pridotite and serpentinized pridotite. the pridotite rocks are composed of harzburgite, lherzolite and replacement dunite which is belong to spinel pridotite facies.paragenesis of ore minerals are ch...

Massive Zn-Cu-Fe sulfide deposits at the Garon Lake Mine occur in three sulfide lenses in a group of metamorphosed rhyolite crystal tuffs, metasediments and basalts. The major ore minerals are sphalerite, chalcopyrite, pyrrhotite and pyrite. Minor associated silicates are actinolite, tremolite, chlorite, albite and quartz. Rounded detrital pyrite, magnetite and chert grains and diagenetic p...
