The results show that the white thick-bedded siliceous rocks have high contents of SiO2 and Al2O3 and high ratios of Al/ and Al2O3/(Al2O3+ Fe2O3). The ∑REE are low, and the North American shale-normalized REE patterns are characterized by enrichment of LREE and absence of Eu and Ce anomalies, which suggest that the white thick-bedded siliceous rocks might have been formed in the continental margin environment and affected significantly by terrigenous constituents. The anatase-rich siliceous rocks have high contents of TiO2, Fe2O3, Cu and V but low Al/(Al + Fe+ Mn) and Al2O3/(Al2O3 + Fe2O3) ratios. The ΣREE are high, the North American shale-normalized REE patterns are obviously characterized by left-oblique to flat styles of curves and slight negative Ce anomalies, implying that they might have been formed in an oceanic ridge environment.
研究结果表明，呈厚层状产出的无矿白色硅质岩具较高的SiO2、Al2O3含量及Al/、Al2O3/(Al2O3+Fe2O3)比值，稀土元素总量很低，其北美页岩标准化配分模式为向右倾的曲线，无明显铈异常和铕异常，表明其形成于受陆源影响的大陆边缘构造环境；赋矿岩系中薄层状富钛硅质岩的TiO2、Fe2O3、Cu、V含量较高，但Al/、Al2O3/(Al2O3+Fe2O3)比值较低，稀土元素总量较高，北美页岩标准化曲线为明显左倾型－平坦型，具弱的负铈异常，表明其形成于洋脊及附近环境。
