简介：摘要：在中国支持干净的煤资源的合理发展和使用，数据在上地区性并且在中国煤的硫，砷和另外的有害元素的年龄分发广泛地被收集，为内容测试了，并且分析。在西北的中国的煤被描绘由对低极其硫的底层；在北中国的太原形成的煤主要有高硫的内容；山西形成的被低硫煤主要描绘；并且在南部的中国的晚二叠的煤有全面的更高的硫内容；另外的区域有低硫煤。在中国的煤的体积的有害踪迹元素的平均内容类似于在北美洲的煤和世界的其余部分的相应内容，而各种各样的元素的内容(Hg，Sb和Se)在到在外壳中的相应百分比的大小是不同的。元素Cr的平均内容，Se，公司，，U，而在对在N中国的早二叠的年龄近来含碳的煤的Hg和CI的平均内容最高，在在S中国的晚二叠的煤的Br在这个国家评价第一。在早、中间的侏罗记煤的Mn的平均内容在NW中国是更高的。在一些煤的有害元素的高内容应该在煤的发展和利用引起特别担心两个。

简介：源自陆地的siliciclastic的一个序列在Baxiandun外面摇庄稼，Qingdao，在在诺思中国之间的中生代collisional边界附近，块(网络控制块)和华南堵住(SCB)。这些低档变形了siliciclastic岩石被greywacke与页岩统治，manganiferous有细密纹理的沙岩，arkose和集团企业层。关于这些岩石的形成有二基本解释。一个人认为这个序列在网络控制块以内被形成，并且是白垩纪Laiyang组和Qingshan组的部分河的外形和暴烈的碎片外形出现在山东地区性的地质的地图上。另一条意见建议这些岩石表示在斜坡和盆外形的混浊depositional系统主要在奥陶纪被扔。重要地基于地观察，petrological分析，和大多数，在这的geochemical结果学习，在Baxiandun节的沉积阶层主要由siltstone，沙岩和mudstone岩性学组成。他们被深海的碎片和混浊存款在一个湖的斜坡和底统治。在Baxiandun节岩石标明日期的U-Pb由岩屑形成的锆石显示来源岩石是很复杂的，他们的年龄被改变从对早白垩纪太古代。源自陆地的岩屑的最年轻的年龄能代表沉积阶层的年龄。因此，我们推断沉积岩石属于早白垩纪深海的湖的沉积序列并且从SuluUHPorogen和华南块边缘的侵蚀有多重来源origined。
