Description

Method for confining sandstone-type uranium ore body output part of oxidation zone between basin floors
Technical Field
The invention belongs to the technical field of sandstone-type uranium ores in basins, and particularly relates to a method for delineating output parts of sandstone-type uranium ore bodies in oxidation zone between basins.
Background
The formation of the interlayer oxidation zone type uranium ore is closely related to the after-oxidation action, shallow uranium-bearing oxygen-bearing underground water penetrates along the exposed part of a basin edge target layer and seeps downwards along a sandstone water-bearing layer sandwiched between mudstone water barriers to the deep part, when oxygen ions in the shallow uranium-bearing oxygen-bearing underground water are continuously and gradually consumed by reducing media such as plant stems, carbon scraps or pyrite and the like contained in target layer gray sandstone, the pyrite can be gradually oxidized and corroded to become limonite (goethite ) and hematite, the color of the gray sandstone also gradually changes to red (yellow) sandstone, the geochemical environment of the water-bearing layer gradually changes from oxidation to reduction environment, and further hexavalent uranium is adsorbed, reduced, precipitated and enriched; along with the continuous penetration of the oxidized water source, the uranium ore body is continuously advanced by oxidation reduction again, and then a classic interlayer oxidation zone type roll-shaped uranium ore body is formed. Correspondingly, the ore-bearing target layer sand bodies can be divided into a red (yellow) oxidation zone, a light grey (green) oxidation-reduction transition zone and a grey (green) primary reduction zone from the basin edge to the basin in sequence; uranium ore is usually positioned in an oxidation-reduction transition zone and is controlled by an after-generated oxidation front line extremely obviously.
At present, the exploration thought of the uranium mine is as follows: drilling is gradually carried out from the basin edge to the basin, and when the drill hole reveals a yellow oxidation zone of a target layer, the drill hole can be determined as an oxidation hole; drilling towards the inner direction of the basin continuously, and determining the drilling hole as a reduction hole when the target layer gray proto-sandstone is exposed by the drilling hole; and then, drilling holes are continuously and repeatedly arranged in the oxidation-reduction transition zone between the oxidation holes and the reduction holes to trace the front edge of the oxidation zone, and the ore searching target area is further continuously reduced until the output position of the uranium ore body is positioned. However, the cost of drilling is about 800 yuan/m, and a 500m drill hole requires about 40 ten thousand costs; considering that the anabolic oxidation causes the pyrite in sandstone to be continuously oxidized and corroded into limonite and hematite and simultaneously accompanies the formation of uranium ore, the two are associated products formed by the same geological action event. Therefore, before further drilling deployment, the trivalent iron minerals in the sandstone samples in the drilled oxidation zone can be subjected to (U-Th)/He dating so as to obtain the time for forming the after-generation oxidation zone and the average rate of forward advancement of the front line, and finally, in the uranium mineralization combining area, the front line of the oxidation zone and the production range of uranium ore bodies can be accurately determined.

step 1.3, according to the basin region structure evolution history and the uranium mineralization dating result of predecessors, determining the main uranium mineralization time of the region as t0。
For example, the depressed west part of Kluyvern in the Heilall basin is selected as a research object, the following Chalk system major grinding crutch river group is used as a main ore-finding target layer, a plurality of drilling exploration lines are arranged and implemented by predecessors, and the red and yellow after-growth oxidation of sandstone at the layer is obviously developed is found in a drill hole; in addition, the U-Pb dating result of the ore sample of the uranium earth surface deposit in the ancient epoch of the region as a tectonic lift-denudation period is 67Ma, so that the main mineralization time t is determined0Is 67 Ma.
Step 2, drilling and selecting the ore exploration part in the step 1 according to the direction of a drilling exploration line in the basin from the basin edge, and numbering the selected drill holes in sequence: drilling 1, drilling 2, … … and drilling n, wherein n is more than or equal to 2; calculating the plane distance L from the drill hole 1 to other drill holes according to the geodetic coordinates of the drill holes by taking the drill hole 1 as a starting pointn-1As shown in fig. 2.
For example, the 3-hole drill hole of the exploration line 0 of the west of the kruse valley is taken as an example, the 3-hole drill hole is respectively numbered as a drill hole 1, a drill hole 2 and a drill hole 3, the orientation from the drill hole 1 to the drill hole 3 is SE130 degrees, and the plane distance from the drill hole 2 to the drill hole 1 is calculated to be L1At 10km, the borehole 3 is at a planar distance L from the borehole 12＝12km。
And 3, respectively collecting the drilling holes selected in the step 2 by using a secondary oxidized sandstone sample, and numbering the sample 1, the sample 2, the sample … … and the sample n.
For example, red and yellow anabolic sandstone stones from the large grinding corner river group in the borehole 1, the borehole 2 and the borehole 3 are respectively sampled, the weight of each sandstone is greater than or equal to 3kg, and the samples 1, 2 and 3 are respectively numbered.
Step 4, respectively carrying out mineral separation on the sandstone samples collected in the step 3, at least separating trivalent iron minerals (hematite, goethite or hydrogoethite) with the weight of more than or equal to 10mg, and sending the trivalent iron minerals (hematite, goethite or hydrogoethite) to a laboratory for (U-Th)/He dating year to obtain the time t formed by the subsequent oxidation of each samplenT is greater since the earlier the formation of the subsequent oxidation occurs closer to the basin rim, the greater the age1>t2>……>tn。
For example, the anagen oxidation times of the sandstone in the large grinding corner river group in the drill holes 1, 2 and 3 are respectively 80Ma, 72Ma and 69Ma measured in years.

Step 5.2, calculating the average rate of the forward propulsion of the after-oxidation in the region: v ═ L1/(t1-t2)+L2/(t1-t3)+……+Ln-1/(t1-tn)]/(n-1)。
For example, it is calculated that the rate of the after-oxidation of the borehole 2 relative to the borehole 1 is V110/(80-72) 1.25km/Ma, the rate of ex-situ oxidation of the borehole 3 relative to the borehole 1 is V212/(80-69) ═ 1.09 km/Ma; intoAnd the average rate of the advancement of the after-oxidation to the basin was calculated to be V ═ 1.25+1.09)/2 ═ 1.17 km/Ma.
