%X 采用ICP-MS测试分析技术,对博格达山北麓油页岩中能指示沉积环境的敏感微量元素做了系统测试分析,采用GB/T 14506.28—2010《硅酸盐岩石化学分析方法》和X射线荧光光谱法测定主要元素和微量元素含量,并探讨了相当硼含量、Sr/Ba、V/Ni比值与沉积环境的对应关系。研究认为:研究区油页岩总体发育于深水湖泊中,该区油页岩磷含量普遍较高,可能由湖盆周围火山喷发后的火山灰带来。磷元素的输入为藻类提供了良好的生长环境,消耗了水体中大量的氧气,形成还原环境,有利于有机质的保存。 Systematacially tested and analyzed the sensitive elements which can indicate sedimentary environment in oil shale using ICP-MS(Inductively Coupled Plasma-Ms Spectrometer) technique,the oil shale samples were collected from southern Bogda Mountain.Major elements and trace elements were examined by silicate rock chemical analysis(GB/T 14506.28—93) and X-ray fluorescent spectroscopy.Meanwhile,The corresponding relationships between the contents of equivalent boron、tatio of Sr/Ba、V/Ni and sedimentary environment were discussed.The results show that the oil shale in study area generally develop from deep lake.The content of phosphate is commonly high,which may be from volcanic ash after volcanic eruption around the lake.This phosphate provides a good environment for algae,which consume lots of oxygen in the water,form reductive environment and is beneficial for the preservation of organic substance
