七十年代初,原地质十二队,在桐柏吴城中、新生代盆地下第三系地层中,发现了天然碱矿,经过勘探证明属于大型天然碱矿床,为改变我国严重缺碱状况,作出了很大贡献。事后,许多同志研究了我省,特别是予南地区中新生代盆地的成矿地质条件,曾预测南阳盆地中的泌阳凹陷,成矿条件较好,有利于形成盐类矿产。一九七六年,在安棚 In the early seventies, the original geological 12 team, in the Tongbai Wucheng, Cenozoic basin in the Tertiary stratigraphy, discovered the trona ore, after exploration proved to belong to large trona deposits, in order to change the situation of China’s severe lack of alkali, Made a great contribution. Afterwards, many comrades studied the mineralization geological conditions in the province, especially the Mesozoic and Cenozoic basins to the south, and predicted the Biyang sag in the Nanyang Basin. The conditions for metallogenesis are good, which are conducive to the formation of salt minerals. In 1976, Anpeng
