Bayan Obo Rare Earth Mine Inner Mongolia China

The unique giant rare earth element REE deposit at Bayan Obo northern China is the worlds largest REE deposit.

Bayan obo deposit geology. The plate tectonic setting regional geology and certain aspects of the economic geology of the iron-rare-earth-niobium ore bodies at Bayan Obo Inner Mongolia China were studied by a team of geologists from the Tianjin Geologic Research Academy and the US. 2015-06-02 The known CARDs include Bayan Obo the worlds largest LREE-Fe-Nb deposit 4 Maoniuping the giant LREE deposit 5 and numerous medium-large LREE deposits 6 7 which are all located along. Geology in China 302 130-137.

Among them is that the Bayan Obo ore deposit is correlated with and has the same origin as the Sailinhudong micrite mound in the southern limb of the Bayan Obo synclinorium. 2013-05-07 Bayan Obo located at the northern margin of the North China Craton Fig. Bayon Obo is the worlds largest known REE deposit.

1 is the largest light rare earth element LREE deposit in the world Supplementary Figure S1. Bayan Obo is a stratabound ore deposit hosted by Proterozoic marble of the Bayan Obo Group. Geological Survey between 1987 and 1989.

2008-01-31 The Bayan Obo ore deposit is a famous world-class giant Nb-REE-Fe deposit located in Inner Mongolia China situated approximately 80km south of the border between China and Mongolia at 10957E and 4146N. Age of the west orebodies of the Bayan Obo deposit with a discussion. Information about ore deposit formation in different epochs.

Here we report in situ Th-Pb dating and Nd isotope ratios for monazite and Sr isotope ratios for dolomite and apatite from fresh drill cores. The deposit occurs in an eastwest trending Mesoproterozoic rift zone along the northern margin of the Sino-Korean Craton. Zongqing Zhang Suohan Tang Jinhuai Wang Zhongxin Yuang and Ge Bai 2003.

To test this model the Bayan Obo ore deposit. They are stratiform deposits hosted by the Middle Proterozoic Bayan Obo Group metasediments mostly in the H8 member consisting of dolomite marble. Abstract The Bayan Obo ore deposit in Inner Mongolia North China the largest-known rare earth element REE deposit in the world is closely associated with carbonatite dykes.

Super large polygenic REE-Fe-Nb deposit Bayan-Obo type discovered as an iron deposit in 1927. However its genesis is still highly debated largely due to pervasive post-ore modifications Smith et al 2015. Baiyunebo deposit Bayan Obo Bayan Obo mining district Baotou City Baotou Prefecture Inner Mongolia China.

Acta Geologica Sinica v. Learn more about the change. The fluorite content of the ores also makes it the worlds largest fluorite deposit.

Bayan Obo ore deposit is the largest rare-earth element REE resource and the second largest niobium Nb resource in the world. Due to the complicated elementmineral compositions and involving several geological events the REE enrichment mechanism and genesis of this giant deposit still remains intense debated. Host strata are quartzite slate limestone and dolomite.

Scarce zircon grains with a wide range of ages and diverse origins have been extracted from the Wu dyke a REE-enriched calcitic carbonatite dyke 2 km from the East Ore Body of the Bayan Obo deposit. It is geologically complex and its genesis is still debated. The Bayan Obo deposit is the largest rare earth element REE accumulation in the world and also an important iron and niobium resource in China Xie et al 2016.

In this deposit the REE ores are mainly hosted in a suite of dolomite which is divided into fine-grained and coarse. The origin of the Bayan Obo ore deposit the largest REE deposit in the world has long been debated and various hypotheses have been proposed. Evidence for magmatic-hydrothermal mineralization related to a carbonatitic complex.

1992-09-01 GEOLOGICAL FEATURES Geotectonically the Bayan Obo REE deposit is situated on the northern margin of the Inner Mongo- lian platform and in the transitional zone between the platform and the Mongolian-Hercynian folded belt with a deep-seated fracture separating the two tec- tonic units. Yuan Zhongxin Bai Ge and Zhang Zhongqin 2000 Trachytic rock and associated fenitization in the Bayan Obo ore deposit Inner Mongolia China. 2008-11-02 The Bayan Obo deposits are divided into the Main East and West orebodies which lie along an eastwest zone more than 18km long.

The regional distributions of the Proterozoic Bayan Obo Group the Archean metamorphic rocks of the Wutai Group which unconformably underlies the Bayan Obo Group and granitic rocks of Archean Caledonian early to late Paleozoic and Hercynian Permian ages in the region are. REE minerals were discovered in 1936 and Nb-bearing ores in the late 1950s.
