通过引进中亚地区系列编图的先进理论和技术,在新疆及其邻区开展了地浸砂岩型铀矿1:200万成矿预测。在对前人资料的二次开发和对工作区及国外邻区现场调研的基础上,结合我国实际,提出最后一场大规模造山运动中度构造活化作用控矿的指导理论;建立了中、新生代沉积盆地表生后生水成成矿体系;揭示了控矿的喜玛拉雅造山运动的时空演化规律,创立了古构造和古水动力系统重塑的新技术;阐明了该区与中亚地区成矿条件及远景的主要差异和该区渗出型油气还原作用对砂岩型铀矿成矿的正反面影响;在编制系列图件和总结评价准则的基础上圈定了2个成矿省、12个远景区,为领导和生产部门战略决策提供了科学依据;编写了方法指南以利于该技术方法的推广。
Through the introduction of advanced theories and techniques of series of maps in Central Asia, a 1: 2 million ore-forming prediction of in-situ leaching sandstone-type uranium deposits was carried out in Xinjiang and its neighboring areas. On the basis of the secondary development of forefathers’ data and on-site investigation in the work area and in the neighboring areas in our country, combined with the reality of our country, we put forward the guiding theory that the last large-scale orogeny controlled the activation of ore- The epoch-epicenter water system of the Cenozoic sedimentary basins reveals the temporal and spatial evolution of the Himalayan orogeny and the establishment of a new technique of paleo-tectonics and paleohydrodynamic system remolding. The main differences of metallogenic conditions and prospect in the sub-region and the positive and negative effects of exudative hydrocarbon-depletion on the metallogeny of sandstone-type uranium deposits in the area; and delineated two mineralization provinces on the basis of compiling series of maps and summarizing the evaluation criteria , 12 vistas for the strategic decision-making leadership and production departments provide a scientific basis; the preparation of methodological guidelines to facilitate the promotion of the technical methods.
