宁夏罗山地区区域地球化学特征及其生态意义

Regional Geochemical Characteristics and Its Ecological Significance in Luoshan,Ningxia

收集并分析了宁夏罗山地区区域地球化学资料,查明了该地区区域地球化学特征,同时,对罗山地区地球化学元素背景含量进行了评价。结果表明,罗山地区部分元素质量分数偏高与奥陶系地层有关,奥陶系深部可能存在中酸性岩体;罗山地区地球化学元素背景含量均处于安全范围内。

The regional geochemical data of Luoshan in Ningxia was collected and studied,and its geochemical characteristics was probed.Meanwhile,its background content of geochemical elements was evaluated.The analysis shows that some high elements content in Luoshan area may be related to the Ordovician strata,and moderate acidic rock mass may exist in the deep Ordovician.The background content of geochemical elements of Luoshan area was safe.
