Abstract

HIGHLIGHTS
(1) Uranium minerals in the Huanglongpu deposit are dominated by titanblende, niobium titanblende, and uraninite.

(2) Uranium minerals are mostly modified by oxidizing fluids which are possibly derived from meteoric water during post crystallization.

(3) The μ-XRF technique has an obvious advantage and widespread application potential in uranium mineralogy.

ABSTRACT

BACKGROUNDThe carbonatite-type molybdenum metallogenic belt in East Qinling is the largest molybdenum metallogenic belt in the world. The Huanglongpu deposit is one of the earliest discovered carbonatite-type molybdenum deposits in China. Our field survey found that the uranium grade of ores in this deposit was higher than the industrial uranium grade, being similar to the Huayangchuan U-Nb-Pb-REE deposit in the Qinling Orogenic Belt. However, the occurrences and mineralogical characteristics of radioactive elements are still unclear.
OBJECTIVESTo explore the main mineral assemblages, U occurrences and other characteristics of uranium ores in the Huanglongpu deposit.
METHODSThe detailed geological survey, μ-XRF, SEM and EDS analyses were carried out on the high-radioactivity ore from the Huanglongpu deposit.
RESULTSThe results showed that major uranium minerals in the Huanglongpu deposit were brannerite, betafite and uraninite, which were associated with calcite, feldspar, pyrite, molybdenite and chalcopyrite. Significant alteration and replacement of uranium minerals were observed in the studied ore sample. The betafite was transformed into Nb-rich Ti-Fe oxides after alteration. After alteration of brannerite and uraninite, a large number of cavities were formed within those minerals. The post-ore fluids were possible from meteoric water. The textural differences of altered brannerite and uraninite on BSE images suggested the variable chemical composition.
CONCLUSIONSμ-XRF technology has a great application prospect in the future research of uranium deposit genesis and prospecting prediction.
