用法例句

In sedimentary environment discrimination diagrams such as 100×Fe2O3/SiO2-100×Al2O3/SiO2,Fe2O3/(100-SiO2)-Al2O3/(100-SiO2) and Fe2O3/TiO2-Al2O3/(Al2O3+Fe2O3),chert samples fall into the areas of the mid-ocean ridges or deep-sea.

研究表明,呈厚层状产出的绿色、棕褐色硅质岩具有较高的SiO2含量,局部受Fe、Mn矿化,Al/(Al+Fe+Mn)比值小,在Fe-Mn-Al三角成因判别图解中,大部分硅质岩样品落入热水沉积区域,微量元素Sr、Zr、Cu、Zn和Ba含量较高,稀土元素∑REE较低,Ce负异常,Eu正异常,北美页岩标准化后配分模式稍向左倾,体现出热水沉积特征;在沉积环境判别图100×Fe2O3/SiO2-100×Al2O3/SiO2、Fe2O3/(100-SiO2)-Al2O3/(100-SiO2)和Fe2O3/TiO2-Al2O3/(Al2O3+Fe2O3)中,硅质岩样品投影到洋中脊和深海区域,说明形成于大洋中脊和深海盆地环境;硅质岩常量和稀土参数变化特征图显示,在剖面中PCL-1、PCL-5和PCL-7采样位置更接近热液中心;硅质岩的形成与板块的汇聚消减产生的以洋中脊和海底热点为中心的洋壳热水系统有关。
