[0002] Black rock series are important ore-hosting formations of rare metals, non-metals and oil and gas source rocks in my country. Common ore-forming elements include platinum group elements, rare earth elements, phosphorus, vanadium, nickel, molybdenum, uranium, gold, silver, manganese, etc. There are more than 30 types of elements, and black rock series are widely distributed in my country, such as Qinghai, Xinjiang, Tibet, Inner Mongolia in the north, Guizhou, Hunan, Guangxi, Zhejiang, Jiangxi, Anhui and other provinces in the south. But not every genetic type of black rock series in every area contains mineral resources, so it is very efficient to use traditional geological prospecting methods to select areas with better ore-bearing properties in such a wide-distributed black rock series. At the same time, it will cause a lot of loss of manpower, material resources and exploration funds

Embodiment Construction
[0026] The present invention is described in further detail below in conjunction with embodiment.
[0027] Below, the present invention will be further described in detail by taking the black rock series developed in a large area in the northwestern part of Hunan Province as an example.
[0028] A method for quickly judging whether black rock series has uranium polymetallic mining value provided by the present invention, the method specifically includes the following steps:
[0029] Step 1: Black rock series sample collection
[0030] Select the black rock series strata that need to be judged, and collect a rock sample with a weight greater than or equal to 200 grams at a thickness of 3 cm from bottom to top in the direction perpendicular to the black rock series rock bedding. The total number of samples is judged according to the needs. It depends on the thickness of the system.
[0031] In this example, three areas with developed black rock series in the northwestern part ...

Abstract
The invention belongs to the technical field of uranium mines, and particularly discloses a method for quickly judging whether a black rock series has uranium-free multi-metal mining value or not. Themethod comprises the steps of: step 1, acquiring a black rock series sample acquisition; step 2, measuring P2O5 content, V, Ni, Cu and Zn element content and the U-Pb isotopic age of black rock series samples acquired in the step 1; 3, judging the phosphorus content of the black rock series sample; 4, judging mineralization elements of the black rock series sample; step 5, and judging the whole rock age of the black rock series sample so as to judge whether the black rock series in the sample collection area has a mining value or not. By means of the method, whether the black rock series of the target area or not can be rapidly judged, so that the prospecting efficiency in the black rock series is improved, and time and capital cost are saved.
