摘要
In this paper, the authors systematical researched the Rare-earth elements (REE) and trace elements of pyrite ores in the deposit. The authors obtained the date indicating that the total REE(ΣREE) of pyrite ores is relatively lower, with pyrite ores’ average ΣREE being 5.54×10-6 but the average ΣREE being only 0.25×10-6 in the single mineral. The result is that Y/Ho ratios are basically consistent with seawater and submarine hydrothermal. Those characteristics provided some new evidence about submarine volcanic exhalative sedimentary mineralization that existing in the Laochang ore deposit.
