37 greywacke samples of Middle and Late Triassic collected from Hongcan well in Zoige were analyzed by ICP-MS for REE and trace elements.
对若尔盖地区的红参一井内中三叠世中期和晚三叠世中期的37个杂砂岩样品进行了ICP-MS微量元素分析,其结果显示这些砂岩样品具有Cs、Rb、Th等元素富集,Sr、Nb和Ta亏损,稀土元素总量较高,且负Eu异常和轻重稀土分异明显等壳源物质的特征;而微量不活动元素的含量及比值特征以及构造环境判别图解的判别结果表明:若尔盖盆地中三叠世中期到晚三叠世中期的沉积构造环境为大陆岛弧,沉积物源受到大陆岛弧的强烈影响。
