in June p>1958, Jiangxi provincial party Committee issued the "decision on unifying and strengthening geological work", which unified the geological teams belonging to the Ministry of Geology, the Ministry of Metallurgical Industry and the Ministry of Coal Industry into Jiangxi Geological Bureau to lead the geological exploration work in the whole province.
since the establishment of the bureau in p>1958, according to the needs of the country in various periods and the possibility of geological conditions in Jiangxi, the general survey of minerals has been expanded to a number of minerals such as oil, sulfur, phosphorus, beryllium and manganese, and a number of achievements have been made in the 196s in rare and rare earth elements and rock salts. Before the Cultural Revolution, the metallurgical and coal departments were established separately. During the Cultural Revolution, the three departments were merged into the geological group of the Provincial Bureau of Heavy Industry again. In 1973, the Geological Bureau resumed its original organizational system. After the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, precious metals such as gold and silver and a large number of non-metallic minerals were included in the exploration plan of the Provincial Geological Bureau.
Since p>1958, the Provincial Bureau of Geology has mobilized the masses to carry out ore prospecting and reporting in the whole province, and through the 1: 2, regional geological survey, geophysical and geochemical exploration, and the exposure, inspection and verification of a large number of light and heavy mountain projects in the whole province, many important mineral bases have been discovered in Lianqian, and a number of metallogenic prospect areas and belts have been formed in the whole province, mainly including:
There are mainly (Jiujiang) Ruichang copper polymetallic ore fields in Jiangxi Province. This is mainly the area where the Paleozoic-dominated fold-fault zone was invaded by many Mesozoic intermediate-acid small intrusions. From the late 195s to the early 196s, the Geological Exploration Brigade of Jiujiang District of the Provincial Geological Bureau (now the predecessor of the Geological Brigade of Northwest Jiangxi) successively discovered promising copper and sulfur ore bodies in the lower part of the iron hat in Chengmen Mountain of Jiujiang and Wushan Mountain of Ruichang. After years of exploration, the reserves of copper reached more than 3.5 million tons, with more than 1 tons of associated gold and more than 4, tons of associated silver. Compared with other primary and secondary deposits or occurrences of copper, iron, gold, silver, lead and zinc, such as Tongling, Dingjiashan, Yangjishan, Dengjiashan, Wujia, Baiyangfan, Tongxichong, Tongjiangling, Dongleiwan, Lion Island, Jinjiwo and Chengmenba, which have been discovered successively, it constitutes an important ore concentration area of the copper belt in the middle and lower reaches of the Yangtze River in Jiangxi Province. In the past, limited by the production conditions, exploration means and capital conditions at that time, the deep prospecting and exploration work was not enough. In the future, the prospecting and evaluation work can be carried out in the deep and many ore occurrences, mineralization points and abnormal points, which can further expand the resource prospect of copper and polymetallic in this area.
2. Xianglushan-Pengshan tungsten-tin polymetallic metallogenic belt. This ore belt is mainly composed of the contact zone formed by the intrusion of the lower Paleozoic old strata into Yanshanian granite and the deposits formed at its outer edge. The west is dominated by Xianglushan Mountain in Xiushui, which constitutes a ore field dominated by skarn-like scheelite. Xianglushan tungsten mine and its surrounding mining areas such as Xingping, Zhangtianluo, Guantang and Gaohu have been working for years. Up to now, the reserves of tungsten trioxide resources have reached more than 3, tons, and there are associated gold, silver, copper, bismuth, gallium and other available resources. In the east is De 'anpengshan tin polymetallic ore field. In the mid-196s, when the regional geological survey brigade of the provincial bureau carried out the Ruichang map of 1: 2, regional geological survey, polymetallic exploration anomalies and skarn outcrops were found. In the winter of 1965, the geological brigade of northwest Jiangxi went up to the mountain to make a general survey for copper. In 1966, the No.52 team was formed to drill into the second-floor tin-rich mine in the No.1 borehole of Zengjialong mining area, and since 1967, it has been transformed into a general survey and exploration work mainly based on tin. Since 1973, the second detachment of the 916 brigade has continued the general survey and exploration of ore fields. Over the years, tin mines such as Zengjialong, Jianfengpo, Poxi, Honghuajian, Peijialong and Huangjinwa, as well as Zhangshiba lead-zinc mine, Baoshan antimony mine and Hongxiban fluorite mine have been discovered and explored. Since the new century, the September 16th Brigade has further expanded the Zhangshiba lead-zinc mine from medium-sized to large-sized, and discovered Dawutou large-sized fluorite mine and Baifunao medium-sized antimony mine, which made Pengshan ore field form a typical ore field with circular zoning according to metallogenic temperature from high temperature-medium temperature-low temperature, which greatly enriched the metallogenic regularity of deposits in the region.
3. Jiuling-Zhanggongshan tungsten, tin and gold polymetallic ore belt. This ore belt was formed by the intrusion of Yanshanian granite into the basement of pre-Sinian system. It can also be roughly divided into eastern and western zones. The W-Sn-Mo belt dominated by Dahukou-Yunshan-Yangchuling-Lianhuashan is in the west. Many mining areas were discovered by the heavy sand survey of the regional survey brigade in 1958 and explored by the northwest Jiangxi brigade. In 1978, the geophysical and geochemical exploration brigade discovered the Yangchuling tungsten deposit by geochemical exploration, and the third team of the 916 brigade was responsible for the exploration of a large tungsten and molybdenum deposit. In the 21st century, a number of small and medium-sized tin (tungsten) mines, such as Maopengdian, Xujiajian and Bazinao, have been discovered in the east by the Northwest Jiangxi Brigade, and new deposit types, such as eastern steep cliff vein wolframite, have also been discovered in the Dahukou area in the west. The 916 Brigade has also made new progress in tin prospecting in Yunshan area.
