Background technology
It is usually covered above sandstone-type uranium mineralization with respect by thicker Quaternary Strata, using soil geochemical prospecting extraction URANIUM DEPOSITS IN THE DEPTHization letter
Breath is one of main method of exploration of sandstone type uranium deposits.Majority is not that ore deposit causes exception in the element uranium exception usually extracted, former
Because being exactly that the uranium element from deep orebody is vulnerable to the influences of many factors when earth's surface is enriched with, including Landscape difference,
Earth's surface flowing water washes away, mankind's activity, geologic body difference etc..These factors can dramatically change uranium abnormal morphology, cause compared with
More false anomalies, if without objective screening anomaly, it can be to miner be looked for cause larger interference.
Invention content
The technical problem to be solved in the present invention is to provide a kind of sandstone-type uranium mineralization with respect soil element uranium exception screening technique, purposes
It is the screening anomaly flow by complete set, the influence of the quick many-sided disturbing factor of removal, extraction ore deposit cause is abnormal, is into ore deposit
Prediction work provides advantageous foundation.
In order to solve the above technical problems, a kind of screening technique of sandstone-type uranium mineralization with respect soil element uranium exception of the present invention, including
Following steps:
Step 1: excluding Landscape interference, research area's high-resolution remote sensing image is obtained, interprets surface vegetation type,
And combined ground sample record divides research area's Landscape, and the original discrete data of uranium is carried out between different landscape area
Leveling;
Step 2: the discrete data after leveling in step 1 is carried out gridding, threshold is set, with drawing uranium element
Geochemistry Abnormal Map;
Step 3: differentiating that non-ore deposit causes exceptions area caused by mankind's activity, the uranium exceptions area for excluding mankind's activity interference is obtained;
Step 4: non-ore deposit caused by differentiating landform in the uranium exceptions area for excluding mankind's activity interference obtained in step 3 causes
Exceptions area obtains the uranium exceptions area after excluding landform interference;
Step 5: non-ore deposit caused by differentiating geologic body in the uranium exceptions area after the exclusion landform of step 4 acquisition is interfered causes
Exceptions area;The uranium exceptions area obtained in step 4 and research area's geologic map are overlapped, if uranium exceptions area and geological epoch
Stratum before Neogene System overlaps, then this differentiates abnormal for the cause of non-ore deposit extremely, obtains the uranium exceptions area for excluding geologic body interference;
Step 6: the uranium exceptions area obtained in step 5 is classified.
In described three, the uranium exceptions area for excluding mankind's activity interference is obtained, is specially interpreted using high resolution image
Factory, village and the road information in area to be studied, factory and village are labeled as dot file on the diagram, pavement marker is line file,
Buffer zone analysis is made to point, line file respectively, the uranium exceptions area that buffering area and step 2 obtain is overlapped analysis, with buffering
The uranium exceptions area that area overlaps differentiates causes exceptions area for non-ore deposit.
In the step four, differentiate that the method that non-ore deposit caused by landform causes exceptions area is high by acquisition research area ground
Number of passes word model data calculate flow direction, flow, gradient index, surface drainage distribution map are established on this basis, to water-based line
File makees buffer zone analysis, and the uranium exceptions area obtained in water system buffering area and step 3 is overlapped analysis, will be delayed with water system
It rushes the consistent uranium exceptions area of area's distribution and extension direction and differentiates and cause exceptions area for non-ore deposit.
In the step six, for uranium exceptions area and geology ore factor are overlapped, grade scale is classification method:
It is abnormal labeled as A classes with the uranium exceptions area that 3 kinds of geology ore factor ranges overlap;With 1-2 kind geology ore factor range weights
The uranium exceptions area of conjunction is abnormal labeled as B classes;It is abnormal labeled as C classes with the uranium exceptions area that geology ore factor range does not overlap.
In the step six, geology ore factor includes ore-bearing formation sedimentary system, secondary grand recessed construction, oxidation-go back
Former three kinds of intermediate zone range.
The advantageous effects of the present invention are:A kind of sandstone-type uranium mineralization with respect soil element uranium exception screening proposed by the present invention
Method can largely reduce the influence of interference information, reject non-ore deposit and cause abnormal, and ore deposit range is looked in diminution, saving look for ore deposit into
This.
Specific embodiment
