Location predication method for deep favorable mineralization part of sandstone-type uranium ore

Abstract

The invention belongs to the technical field of basin uranium mineralization predication and mineralization potential evaluation, and particularly relates to a location prediction method for a deep favorable mineralization part of a sandstone-type uranium ore. The location prediction method comprises the following steps of a first step, according to area stratum information, defining a main ore finding target layer of the sandstone-type uranium ore; a second step, selecting devices and defining a depth range; a third step, defining a favorable deposit phase zone; a fourth step, overlapping the areas obtained in the second step and the third step in a layer manner, and numbering different layers; a fifth step, determining an undergone structure reconstruction function of the defined area; a sixth step, determining an underground water supplementing-path-discharging system of the defined area; and a seventh step, determining the result according to the fourth step, the fifth step and the sixth step, and finally defining the favorable mineralization part. The location prediction method settles technical problems of long time consumption and high cost in an existing prediction method, and furthermore can perform location prediction on the favorable mineralization part of sandstone-type uranium ore at deep portion of the basin quickly and efficiently in a low-cost manner.

Description

technical field [0001] The invention belongs to the technical field of basin uranium ore-forming prediction and ore-forming potential evaluation, and specifically relates to a method for locating and predicting favorable ore-forming positions in the deep part of sandstone-type uranium deposits. Background technique [0002] Sandstone-type uranium deposits occupy a very important position in the global resource structure, and are also one of the four traditional industrial types of uranium deposits in my country. Since my country focused on in-situ leaching sandstone-type uranium deposits in the 1990s, a large number of uranium deposits have been discovered in many basins in northern my country. However, with the rapid development of nuclear power in my country, higher requirements have been placed on the reserve of uranium resources. Since the prospecting work for sandstone-type uranium deposits began, uranium resources in the shallow part of the basin have been discovered on...
