Beiya mine, where gold and other minerals are dug up in Heqing county in Yunnan, is just one of the main areas operated by the Yunnan Gold and Mineral Group and
2019. 9. 1.· Simultaneously, we consider the Beiya gold mine in Yunnan as an example. The nonlinear 3D density-difference inversion technology, which is restricted by geological information, is explored to obtain the 3D density body structure below 5 km in the mine area, and the 3D structure of the deep and concealed rock masses are obtained using the density constraints of the intermediate-acid-complex

A handful of gold mines are known, but these were relatively small exploitations. We therefore pay attention to gold mining mainly where it was co-exploited alongside other metals, such as at the Beiya 北衙 Mines in Heqing 鹤庆.
The Heqing area, located in the Sanjiang ore belt, China, consists of the Beiya gold orefield related to the alkaline porphyry, the Emeishan volcanic mafic rocks and a series of sedimentary rocks
2019. 3. 1.· Robust dating of hydrothermal deposits is critical to understand ore genesis, which depends on judicious selection of mineralization-related chronometers, especially for complex polymetallic mineral systems. The Beiya deposit in southwest China is a world-class polymetallic gold system (11.9 Moz Au at a grade of 2.52 g/t) and the main mineralization is considered as skarn-type.

The Beiya skarn gold deposit is located in the eastern Tethyan orogenic belt in western Yunnan province,China. It is one of the largest gold deposits in China, with significant amounts of silver
2016. 3. 1.· The Beiya gold deposit is located in Heqing County in Yunnan Province, SW China, between the Qinghai–Tibet plateau and the Yangtze plate ().The deposit and associated alkaline porphyries are hosted in stratigraphy belonging to the upper Permian Emeishan Formation, the lower Triassic Qingtianbao Formation, the middle Triassic Beiya Formation, the upper Triassic Zhongwo
2017. 6. 1.· 1. Introduction. Recent exploration conducted by Yunnan Gold & Mineral Group Co., Ltd in the Beiya orefield in western Yunnan province, southwest China, indicates that has proven reserves of more than 370 tonnes (t) Au at an average grade of 2.52 g/t Au, approx. 200 million t Fe at an average grade of 33.92% TFe (total iron), 0.8 million t Cu at an average grade of 0.61% Cu, 1.55 million t Pb

The Yao’an vein-type gold deposit is located in the Ailaoshan-Jinshajiang alkaline intrusive belt, Yunnan Province, China, and is associated both in time and space with 33.5±1.0-Ma-old alkaline intrusions. The gold mineralization is associated with potassic wall-rock alteration. The REE distribution patterns of secondary K-feldspar are generally similar to those of the igneous perthite but
