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 maroon or light brown yellow, it is initially judged as acidic rock;

[0017] 2. For volcanic rocks that are preliminarily judged as acidic rocks, conduct a full analysis of rock silicates. When SiO in volcanic rocks 2 If the content is greater than 65%, it is judged that the volcanic rock is acidic rock;

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

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

[0020] 5. Judgment of fluoritization alteration in the contact zone. When the color of the altered mineral is yellow, green, blue or purple, with glass luster, and its Mohs hardness is 4, it is judged as fluoritization alteration;

[0021] 6. De...

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 method for prospecting hydroxysilicate-type beryllium ore, in particular to a method for prospecting hydroxysilicate-type beryllium ore for guiding the prospecting of beryllium ore in Late Paleozoic volcanic rocks in northern my country. Background technique [0002] In recent years, the beryllite lump ore used to produce industrial beryllium oxide in my country has been in short supply, and there is an urgent need to find other beryllium ore resources to replace beryl lump ore. Since 2006, the No. 216 Brigade of the Nuclear Industry has carried out beryllium ore exploration in Xinjiang and the Baiyanghe area of ​​Buxar County. At present, there is no established ore prospecting model for hydroxysilicate-type beryllium ore in China. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for prospecting hydroxysilicate-type beryllium ore that successfully realize...
