Analysis of genetic model of siliceous rocks of the Middle Jurassic Jiulongshan Formation in Ming Tombs area in Beijing and their geological significance

doi:10.7605/gdlxb.2021.05.062

Abstract

Abstract: The terrestrial sedimentary strata developed in northern China during the Late Mesozoic. The Middle Jurassic Jiulongshan Formation is a typical representative of this period. A set of siliceous rocks emerged from the Jiulongshan Formation in the Changping Tombs area. The Ge/Si value of the siliceous rocks is about 3-4 μmol/mol, between the hydrothermal fluid(~11 μmol/mol) and the river(~0.7 μmol/mol), except for a few samples with high values. The REE distribution has obvious positive Eu anomalies(1.2~2.4,with an average of 1.58),and is relatively stable overall,without obvious Ce anomalies. It has both the characteristics of rivers and hydrothermal fluids. Through semi-quantitative analysis of REE characteristics and Ge/Si value,we believe that the source of siliceous rocks in the Jiulongshan Formation came from a mixture of hydrothermal fluids and rivers,of which the hydrothermal contribution is about 30%.

摘要： 中生代晚期中国北部陆相沉积地层发育,中侏罗统九龙山组是本时期沉积的典型代表。北京十三陵地区九龙山组出露有一套硅质岩,其Ge/Si值介于热液流体(~11 μmol/mol)和河流(~0.7 μmol/mol)之间,整体为3~4 μmol/mol,少数样品的Ge/Si值较高;其REE分配具有较明显的Eu正异常(1.2~2.4,平均1.58),整体比较平稳,无明显Ce异常,兼具河流和热液的特征。通过对REE特征和Ge/Si值进行半定量分析,本研究认为九龙山组硅质岩的物源来自热液和河流的混合,其中,热液贡献约为30%。
