南岭及其邻区多金属成矿条件与开发方向

本文在前人工作的基础之上,对南岭及其邻区的地层、岩浆岩、变质岩和构造综合研究与对比分析后认为,该区成矿条件优越,成矿条件复杂,表现出多金属矿产的共生性与伴生性。开发方向应该充分利用这两个特性,依靠科技,实行投资倾斜,减少资金沉淀,加强综合找矿、综合开采、综合冶炼、综合加工。在提高资源增值率,扩大经济效益的同时保护生态环境,完善产业结构与生产力布局,尽快地把该地区建成有色、稀有、黑色金属工业基地。

CONDITIONS OF THE ORE GENESIS AND THE EXPLOTTIVE DIRECTION OF METAL MINERAL RESOURCES IN THE NANLING RANGE AND ITS SURROUNDING AREA

Through typical surrey and scientific investigation of the exploitive state of metal mineral resources in the Naling area and considering the economic geology, economic geography, advances of science and technology, and market forecast of the area, we think that the conditions of ore genesis in the area are excellent. The exploitive direction should be:1.Concentrate funds, deploy qualified personnel and adopt advanced industrial methods to form a joint management group of nonferrous- metals in the Nanling area; carry out a systema-lized production system of looking for minerals -exploration-exploiting-smelting-industrial products; carry out a policy of looking ahead and behind; and establish various industrial bases of the nonferrous metals in the Nanling area on the basis of the large and medium cities which lie along the trank lines of the Zhejiang-Jiangxi, Hunan-Guangxi and Beijing-Guangzhou railways.2.Bring into full play the superiority of local rich natural resources and cheap labour and make use of the characteristics that by processing the primary products of rare metals, rare-earth metals and dispersed element minerals it is relatively easy to build up the industrial bases of rare metal raw materials in large and midium cities along the Zhejiang-Jiangxi railway and the industrial bases of rare-earth metal raw materials in large and medium cities along the Guang-dong-Jiangxi railway.3.Develop the existing medium and small iron and steel enterprises steadily and take as the direction the creation of new iron and stell industry materials and products by comprehensive processing and utilization of ferrous metals, nonferrous metals, rare metals, rare-earth metals and dispersed elements. Another direction is to strengthen the study of geologically basic theory and prospecting work to expand deposits and increase the iron ore reserves for the development of the iron and steel industry.
