中文摘要:

贵州位于上扬子陆块，1992年王砚耕率先提出“一块两带”地质构造单元，即扬子陆块、江南造山带、右江造山带，已为地学界公认。随地学理论实践和研究程度深入，1996年又将“一块两带”细分为“一盆三带”，包括:四川前陆盆地(属扬子陆块)、鄂渝黔前陆盆地褶皱冲断带(属扬子陆块)、江南造山带、右江造山带。贵州学者曾对深部断裂进行过研究，并试图划分地质构造单元及确定深部分界线位置，推测结果多数表现为地表断裂变形特征，可能存在一定局限性。因此，科学应用地质、物探相结合方法，研究造山活动后隐伏的地质问题具有重要意义。依据重力、航磁、地质等区域资料，推断了深部的隐伏断裂和“一盆三带”分界线，研究了基底构造变形特征，以服务深部的地质找矿预测、成矿规律研究。

英文摘要:

Guizhou is located in the Upper Yangtze continental blockIn 1992，Wang Yangeng first proposed the “one block and two belts” geological tectonic unit，namely the Yangtze continental block，the Jiangnan orogenic belt，and the Youjiang orogenic belt，which have been recognized by the geoscience communityWith the improvement of the theory and practice of geography，in 2011，the “one block and two zones” was subdivided into “one basin and three zones”，including:the Sichuan foreland basin(belonging to the Yangtze block)，and the fold thrust belt in the foreland basin of Hubei，Chongqing and GuizhouIt belongs to the Yangtze block，the Jiangnan orogenic belt，and the Youjiang orogenic beltMany scholars in Guizhou have studied the deep faults and tried to determine the location of the tectonic units and the boundaries of the deep partsThe results are mostly deformation features of surface faults，which may have certain limitationsTherefore，it is of great significance to apply scientific methods of geology and geophysical exploration to effectively solve deep geological problems and study the hidden distribution of different geological bodies after orogenic activitiesAccording to the existing regional data of gravity，aeromagnetic，geology，etc，the deep faults are jointly inferred，and the structural deformation characteristics of the basement are studied to serve the deep geological prospecting prediction and mineral distribution research
