Discussion on Metallogenic Geological Characteristics and Genesis of Shuanghe Barite-Fluorite Deposit in Wuchuan, Guizhou Province
Fluorite is mainly used in the steel and chemical industries. The market demand for fluorite has been growing, and fluorite has become a strategic mineral in China. With the exhaustion of fluorite resources in the main producing areas (Zhejiang, Hunan, etc.), the barite fluorite deposit has been paid more attention and utilized in Wuling Mountain area (the adjacent place of Chongqing, Guizhou and Hunan). Through field geological work, the geological characteristics of shuanghe Barite-fluorite deposit in Wuchuan were studied, it is considered that the Shuanghe Barite-fluorite deposit in Wuchuan is controlled by the lower Ordovician Honghuayuan formation and the NW trending development of tensile fractures, the ore-bearing horizon is the Lower Ordovician Honghuayuan group, It is proposed that the ore-prospecting direction of the barite-fluorite ore body is controlled by the Lower Ordovician Honghuayuan Formation and the NW direction structure, It is helpful for further prospecting work in Wuling Mountain area of Guizhou province, it will actively support the development of mining industry in the region and provide services for poverty alleviation.
Metallogenic Regularity and Prospecting Potential of Dachang gold Ore Concentration Area in Qinghai Province
Dachang gold ore concentration area is located in Maduo township, Qumalai County, Qinghai Province. It is located in the middle of the gold and antimony metallogenic belt in the north Mount Bayankala , whichis known as the "gold belt" in Qinghai Province. The estimated gold resource amount has exceeded 190 t.Based on the systematic collection and analysis of the previous research results, the metallogenic rules of the gold ore concentration area are analyzed and summarized to evaluate the regional ore-prospecting potential.Research shows that gold deposits mainly occur in the Triassic strata and is controlled by Gande-Maduo deep fault belt, Dachang, Zhajiatongna, Jiageilongwa, Shaorio and Zhalayi gold deposits are distributed on both sides of the fault in a beadlike manner, and the type of deposit is "middle-low temperature hydrothermal tectonic-altered rock type" gold deposit, the metallogenic epoch of the late Indosinian. The ore-forming materials are mainly derived from the initial ore-bearing hydrothermal fluid, and some of them are extracted from the surrounding rock strata. There are good metallogenic potential in the overburden area and the deep part of the gold deposits, including Apengeyiand Geyonggamakao gold point, which are important prospecting areas in this area.
