The Huangyangshan super-large graphite deposit, located in the East Junggar area of the Xinjiang Province, is hosted in and has closely temporal, spatial, and genetic relationships with the Huangyangshan alkaline granites. There are such silicate minerals as amphibole, biotite, pyroxene, and plagioclase occurring in the graphite-bearing granites. T...

The Huangyangshan super-large graphite deposit is located in the Qitai area of East Junggar in Xinjiang Province, China. This deposit is well known for its distinguishing properties, including the alkaline granite complex that hosts the graphite ore, the dominantly orbicular structure developed in the graphite ore, and the association of graphite w...

The Sayashk tin (Sn) deposit is located within the southern part of the Eastern Junggar orogenic belt in Xinjiang Province and forms part of the Kalamaili alkaline granite belt. There are many Sn polymetallic deposits in the area. To constrain the age, genesis, and tectonic setting of the Sayashk tin deposit in the East Junggar region, we conducted...

The Zhangxuan district in North China, also known as Northwestern Hebei “Golden Triangle,” develops many intrusion-hosted lode-gold deposits. The Dongping gold deposit in the Zhangxuan district is well known for its unique hosting of rocks and ore mineral assemblages. Magnetite and pyrite are common minerals that widely exist in ores of the Dongpin...

The Haobugao Pb–Zn deposit located in the southern Great Xing’an Range (SGXR) is one of the most important deposits within the Huanggangliang–Ganzhuermiao polymetallic metallogenic belt. Xiaohanshan quartz monzonite porphyry and Wulandaba granodiorite are present in the ore area and are assumed to be closely related to the mineralization. In this s...

The Southern Great Xing'an Range (SGXR) hosts a number of Early Cretaceous Sn and associated metal deposits, which can be divided into three principal types according to their geological characteristics: skarn type deposits, porphyry type deposits and hydrothermal vein type deposits. Fluid inclusion assemblages of different types of deposits are qu...

The southern Great Xing’an Range (SGXR) is one of the most important non-ferrous metal ore concentrating areas in China, and a large number of Pb-Zn and associated metal deposits have been found and mined in this area. The Early Cretaceous deposits of SGXR can be divided into three principal types according to their geological characteristics: skar...

The Dacaoping and Sadaigoumen Mo deposits were recently discovered along the northern margin of the North China Craton. In this paper, we present new zircon U–Pb ages, Hf isotope data, and whole-rock major and trace element data for the monzogranite and granodiorite in the Dacaoping Mo deposit and the monzogranite in the Sabagaogoumen Mo deposit, a...

The Sadaigoumen Mo deposit is a typical porphyry‐type deposit which is located in the northern margin of the North China Craton (NCC), China. Mineralization of the deposit mainly occurs as finely disseminated within the host granites. To get a better understanding of the ore‐forming process of the deposit and the genetic link between mineralization...

The Dacaoping and Sadaigoumen Mo deposits were recently discovered along the northern margin of the North China Craton. The newly determined Re–Os isochronous age of molybdenite from the Dacaoping Mo deposit is ca. 147 Ma, and the Re–Os model age of molybdenite from the Sadaigoumen Mo deposit is ca. 248 Ma, which represents two of their respective...

The Zhuanshanzi gold deposit lies in the eastern section of the Xingmeng orogenic belt and the northern section of the Chifeng‐Chaoyang gold belt. The gold veins are strictly controlled by a NW‐oriented shear fault zone. Quartz veins and altered tectonic rock‐type gold veins are the main vein types. The deposits can be divided into four mineralizat...

The Meilin porphyritic biotite granite is located along the northern margin of the North China Craton and the northern central orogenic belt. The Meilin granite is complex but is dominated by a porphyritic biotite granite. Isotopic dating using zircon U-Pb LA-ICP-MS analyses indicates that the porphyritic biotite granite was emplaced at 1715.6 ± 9....

Discovered and mined in recent years, the Jinchangliang gold deposit has not yet been studied in its genetic type. In this paper, the geological features of ore deposit, S isotopic composition, metallogenic age and elements geochemical of the granite closely related to mineralization were discussed. The results of the geological features of ore dep...

In this paper, the authors propose a new magnetic control method for spiral-type wireless capsule endoscope (WCE). A cylindrical external permanent magnet (EPM) is used to generate rotational magnetic field to manipulate the synchronous rotation of a magnetic spiral-type WCE. To verify the feasibility of this method, a handheld actuator (HA) contro...
