The Western Qinling orogenic belt (WQOB) is one of the most important prospective gold districts in China, with widely distributed Indosinian intermediate–acidic intrusions. Liziyuan Au deposit a representative northern WQOB, hosting several sections spatially associated igneous rocks. hosted by meta-sedimentary volcanic rocks Cambrian–Ordovician Group and Tianzishan monzogranite. Two periods, ...

the area is located 20 km northwest of kashmar and about 4 km of kalateh taimour in khorasan razavi province. the study area is part of tertiary volcanic-plutonic belt north of daruneh fault and its situation in tectonic inliers between two important active faults, doruneh and taknar. volcanic rocks are mainly intermediate to acid pyroclastic type. they formed during early tertiary. the volcani...

The Big Jim complex is a concentrically zoned ultramafic to felsic plutonic complex which intruded the pelitic Chiwaukum schist. Most of the major plutonic rock types (from websterite through hornblendite, gabbronorite, hornblende gabbro and diorite, to granodiorite) enclose harzburgite and metaperidotite xenoliths similar to foliated metaperidotite lenses included in the Chiwaukum schist. The ...

Jinling complex pluton is a key part of the Mesozoic magmatic belt in eastern North China Craton. However, its petrogenesis still being debated. The complex, mainly composed biotite diorites, hornblende diorite, augite (quartz) monzonites, and quartz outcropped Huashan Heitieshan. This paper studies zircon geochronology, Hf isotope, Sr-Nd-Pb isotope monzonites. samples have high contents Cr, Ni...
