Embodiment Construction

[0015] The present invention comprises the following steps in turn:

[0016] 1. Judging the volcanic rock, when the volcanic rock is light yellow, light red, light brown red or light brown yellow, it is preliminarily judged as acid rock;

[0017] 2. For volcanic rocks that are initially judged to be acidic rocks, perform a full analysis of rock silicates. When the SiO in the volcanic rocks 2 If the content is greater than 65%, it is judged that the volcanic rock is an acid rock;

[0018] 3. For volcanic rocks judged to be acidic rocks, carry out rock and mineral identification to find out granite porphyry;

[0019] 4. Along the boundary between granite porphyry and other acidic rocks, determine by tracing method, and outline the contact zone of granite porphyry;

[0020] 5. Judgment of fluoritic alteration in the contact zone, when the color of the altered minerals is yellow, green, blue or purple, and has vitreous luster, and its Mohs hardness is grade 4, it is judged as fl...

Abstract

The invention relates to a prospecting method for large and extra-large bertrandite-type beryllium ores, and the prospecting method comprises the following steps of (1) primarily judging volcanic rock to be acid rock when the volcanic rock is pale yellow, light red, light maroon or light isabelline; (2) judging the volcanic rock to be the acid rock when content of silicon dioxide (SiO2) in granite porphyry is more than 65 percent; (3) finding out the granite porphyry; (4) drawing a contact zone of the granite porphyry along a boundary of the granite porphyry with other acid rock; (5) judging whether altered minerals in the contact zone are the fluoritization alteration or not; (6) juding whether the fluoritization alteration is produced in a streak shape or not, and judging the fluoritization alteration to be near-ore alteration when the fluoritization alteration streaks produced in a streak shape are more than 3; and (7) judging volcanic rock to be the bertrandite-type beryllium ores when the volcanic rock simultaneously has the characteristics of the acid rock and the near-ore alteration. The prospecting method is applied to Poplar River beryllium deposit, an extra-large beryllium deposit is implemented, and more than 20 thousand tons of beryllium oxide resources are submitted.

Description

technical field [0001] The invention relates to a ore prospecting method for large-extra-large hydroxysilicon beryllium type beryllium ore, in particular to a large-extra large hydroxysilicon beryllium type beryllium ore prospecting for guiding beryllium ore prospecting in late Paleozoic volcanic rocks in northern my country method. Background technique [0002] In recent years, the beryl block ore used for the production of industrial beryllium oxide in my country has become increasingly scarce, and it is urgent to find other beryllium ore resources to replace the beryl block ore. Since 2006, the 216th Brigade of Nuclear Industry has carried out beryllium ore exploration in Xinjiang and Baiyanghe area of ​​Buxel County. At present, there is no set of formed prospecting model for hydroxysilicon beryllium type beryllium ore in China. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a large-to-extra-large hydroxysili...
