国内资源的开发大区域地质构造调查:日本的矿床赋存形态复杂,且大多数是不出露地表的盲矿床。所以,各个企业不能实施有效的探矿。因此,日本在谋求以大区域调查、详细调查和企业探矿的三阶段方式的探矿。作为三阶段方式探矿的一环,大区城地质构造调查,是对于需要迅速推进国内金属矿物探矿的区域,为了在总体上查明地层状 Development of Domestic Resources Large regional geological structure survey: Japan’s ore deposits are complicated in shape and most of them are blind deposits that do not reveal the surface. Therefore, all enterprises can not implement effective prospecting. Therefore, Japan is pursuing a three-phase prospecting program involving large-area surveys, detailed investigations and business prospecting. As a part of the three-phase prospecting, the investigation of the geological structure of the Great Wall City is an area that needs to promptly promote prospecting of domestic metal minerals. In order to ascertain generally the stratiform
