X-ray analyses indicate that lattice parameters decrease due to Cu-doping; while XPS results show that Cu-doping leads to positive chemical shifts of the Cu 2P1/2 and La 3d5/2 and 3d3/2 levels, implying that Cu-O and La-O bondings are strengthened and their bond lengths are shortened; while magnetization measurements show that after 8 hours' Arannealing, the Neel temperature of Cu-rich sample is about 31K higher than that of the sample without Cu doping, indicating that the three-dimensional antiferromagnetic correlation is enhanced.

Greywacke samples of Middle and Late Triassic collected from Hongcan well in Zoige were analyzed by ICP-MS for REE and trace elements. The result shows that these samples were originated continental crust because they enriched in Cs,Rb,Th and high REE contents and depleted in Sr,Nb and Ta. Negative Eu anomalies and strong differentiation between heavy and light REE are significant. Both the contents and ratios of the inactive trace elements and the results based on discriminant diagrams indicated that the sedimentary tectonic setting of Zoige Basin was dominated by continental island arc and the sediment in this basin was strongly affected by continental island arc between Middle and Late Triassic.

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。
