Description
Technical field
The invention belongs to technical field of geological exploration, and in particular to a kind of interlayer oxidation zone type sandstone
The preliminary recognition methods of uranium ore oxidized zone.
Background technology
Interlayer oxidation zone type SANDSTONE URANIUM DEPOSITS has distinctive geochemical characteristics, and such uranium deposit is produced
Near distinctive oxidationreduction geochemical barriers, mineral deposit is in roll, and ore deposit volume is located at oxidized zone
Near preceding forward line, find and prediction front of the oxidation zone line is that interlayer oxidation zone type uranium deposit looks for ore deposit prompt
Footpath.And active uranium element to be one kind come from interlayer oxidation zone type uranium deposit deep earth chemistry ring
The good instruction element in border, mobile uranium geochemical anomaly can indicate interlayer oxidized zone molding sand rock
Uranium ore deep oxidation-reduction geochemical environment.In oxidized zone, uranium element is presented sexavalence in work
Dynamic is dissolved in the underground water migrated along sand body, and uranium is easy to carry out Vertical Migration, therefore, oxidation
Height with mobile uranium is presented is abnormal, with the consumption of underground water oxygen, meets reductant,
Formed oxidationreduction geochemical barriers, herein uranium from sexavalence be changed into tetravalence precipitate and by beam
Binding decrease uranium significantly carries out the possibility of Vertical Migration to earth's surface, so, in oxidationreduction
Nearby mobile uranium is reduced rapidly geochemical barriers, and to primary zone, mobile uranium greatly reduces so as to drop
To background value.Therefore, using mobile uranium geochemical anomaly to interlayer oxidation zone type SANDSTONE URANIUM DEPOSITS
The preceding forward line of deep oxidation band carries out primary election, then needs with reference to geology, Geophysical-chemical and further surveys
Spy data is modified to front of the oxidation zone line, the primary election of front of the oxidation zone line, for mobile uranium
Prediction of the data in favourable U metallogeny area is of practical significance.
