富铌的岛弧玄武岩则是中等到高碱的镁铁质熔岩，它们相对于正常的岛弧玄武岩含有较多的高场强元素（HFSE）。
Niobium-enriched arc basalts are mildly- to highly-alkalic mafic lavas that contain relatively higher amount of high field-strength elements (HFSE) than normal arc lavas.
微量元素含量变化大，但总体变化趋势一致，即表现出大离子亲石元素(LILE)富集而高场强元素(HFSE)亏损。
The intermediate rocks contain variable contents of trace elements, but generally have a similar variation trend such as systematic enrichment of LILE and depletion of HFSE.
毒砂、黄铁矿微量元素含量呈现出随着成矿流体从早期到晚期的演化而减少，并普遍亏损高场强元素，富集LREE的特征；
The ore-forming fluid had weak reducibility. Race elements of arsenopyrite and pyrite were reduced by ore-forming fluid with the evolution. There were relatively high LREE and low HREE.
