摘要: 燕山赤城地区中元古界(高于庄组和雾迷山组)硅质岩具低Al2O3和TiO2 (质量分数平均为0.06%和0.01%)，高TFe2O3 (质量分数平均为0.68%)，高Fe与Ti质量分数比和(Fe + Mn)与Ti质量分数比(分别平均为131和140)的特征。区内硅质岩中MnO与TiO2质量分数比大于远洋环境硅质岩，且Fe2O3与TiO2质量分数比较高，而Al2O3与(Al2O3 + Fe2O3)质量分数比较低，表明其形成于远离陆源碎屑干扰而受热液作用影响的远岸环境，硅质主要来源于海底热液。
Abstract: The content of Al2O3 and TiO2 (the mass fraction was 0.06% and 0.01%, respectively) of silicalite was low and the content of TFe2O3 was high (the average mass fraction was 0.68%) in Mesoprote-rozoic Erathem (Gaoyuzhuang and Wumishan Formations) in Chicheng Area of Yanshan Belt, and it had characteristics of high ratio of Fe/Ti, Fe + Mn/Ti (the average value was 131 and 140, re-spectively). The mass fraction ratio of MnO/TiO2 of silicalite in the area was higher than that of sil-icalite in the ocean environment, and it was characterized by high ratio of Fe2O3/TiO2, low ratio of Al2O3/(Al2O3+Fe2O3). All these characters indicate that silicalite is formed in the far shore envi-ronment of which keeps away from the disturbance of terrigenous detrital and is influenced by hydrothermal process. The siliceous matter mainly comes from the seafloor hydrothermal fluid.
