the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

In this presentation questions are raised about a melt-restite unmixing model proposed by Barton and Sidle (1994) for the myrmekite-bearing Waldoboro granite complex along the southeastern coast of Maine (USA). This complex consists mostly of granite/granodiorite gneiss and granite, but smaller masses of quartz diorite, aplite, pegmatite, leucogranite, tourmaline granite, and granite porphyry o...

The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...

The Qulong porphyry copper and molybdenum deposit is located at the southwest margin of the Lhasa Terrane and in the eastern region of the Gangdese magmatic belt. It represents China’s largest porphyry copper system, with ∼2200 million tonnes of ore comprising 0.5 % Cu and 0.03 % Mo. The mineralization is associated with Miocene granodiorite, monzogranite and quartz-diorite units, which intrude...

Magmatic zircon tends to present characteristic trends in trace element compositions response magma petrogenesis and metallogenesis, such that may provide a window into melt evolution not accessible by whole rock chemistry. The Yangla large Cu deposit is located the central part of Jinshajiang Suture Zone, southwest China, constrained between Faults. In this study, elements hafnium isotopic zir...

The Dongxiang tungsten–copper deposit is a large W–Cu located in the northeast of Jiangxi province south China. Previous studies have mainly considered geochemical and isotopic attributes ore deposit, but information still lacking on genesis setting mineralization-related intrusive rocks. This paper presents systematic elements Sr–Nd–Hf data granodiorite porphyry. porphyry intermediate–acidic c...
