We present a study on the Dongguashan quartz diorite stock which is largest Early Cretaceous intrusion associated with skarn-porphyry polymetallic ore deposit in Tongling Ore Cluster, Middle-Lower Yangtze Metallogenic Belt East China. The show massive texture without obvious foliation, and intrusive contact was locally observed inside of stock. anisotropy magnetic susceptibility (AMS) results t...

the asinawa iron ore is located about 3km to the southeast of penjween town, sulaimaniya governorate, kurdistan region, northeastern iraq near the iraq-iran border. the exposed iron ore deposit is about 60 and 400m wide and long respectively. the present study is the re-study of the geology and geochemistry of the asnawan iron ore deposit  and concluded that the country rocks are consist of hor...

Abstract Chemical exchange between silicate magmas and carbonate rocks has major implications for igneous fractionation, atmospheric CO2 flux, formation of mineral deposits. However, this process is only partly understood, long-standing questions whether, where, how can be digested by melts remain controversial. We describe evidence pervasive chemical melt rock in a shallow porphyry setting dri...

zafarabad iron deposit is located northwest of divandareh, in the northern margin of sanandaj-sirjan plutonic-metamorphic zone. the deposit is in lentoid to tubular shape, within a shear zone and occrrued in host rocks of calc-schist and limestone. magnetite with massive, cataclastic and replacement textures are the main phases, while pyrite and other sulfide minerals are found. major and trace...
