Abstract

HIGHLIGHTS
(1) Fenitization can be used to fingerprint carbonate-related REE deposits.

(2) In situ trace element data of aegirine-augite in fenitization veins can be used as a geochemical index for mineralization.

(3) High REE flux in the fenitization vein was one of the factors forming a number of REE minerals.

(4) Combining whole rock trace, in situ trace and photomicrograph analysis improved the understanding of geological phenomena.

ABSTRACT

BACKGROUNDIn recent years, whole-rock inductively coupled plasma-mass spectrometry (ICP-MS) trace and in situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) trace element analyses have been increasingly more widely used in the field of earth sciences. Fenitization is a common type of alteration in carbonate-type rare earth deposits, but the relationship between the trace element characteristics of altered minerals and rare earth mineralization is not clear.
OBJECTIVESTo better understand the relationship between fenitization and REE mineralization in the Maoniuping deposit as well as to provide references for prospecting carbonate-related (including alkaline rock) REE deposits.
METHODSTrace elements for aegirine-augite and arfvedsonite in different stages of fenitization veins (ore-bearing or barren rocks) from the Maoniuping deposit, Dagudao area were analyzed by ICP-MS and LA-ICP-MS.
RESULTSIn situ trace elements of aegirine-augite in different stages of fenitization veins showed that La/Nd (0.19-0.23), LREE/HREE (6.58-7.79), Ce/Nd (0.95-1.11), (La)_N/(Yb)_N (2.07-2.33) values of aegirine-augite in ore-bearing veins were higher than those of barren veins.
CONCLUSIONSCompared with whole rock trace elements, high contents of La, Ce, LREE, ΣREE in mineral veins, strong differentiation of light and heavy rare earths may represent fenitization-related fluid with high rare earth flux. The occurrence of fenitization veins and the whole-rock trace and in situ trace geochemical indicators of aegirine-augite in veins may provide references for the prospecting and exploration of carbonate-type rare earth deposits.
