五大连池药泉山矿泥区火山矿泥元素垂向变化趋势研究

Study on the Vertical Variation Trend of the Elements in Volcanic Mud in Yaoquanshan Mud Area of Wudalianchi

为研究五大连池药泉山矿泥区火山矿泥元素垂向变化趋势,通过ICP-OES法对五大连池药泉山矿泥区火山矿泥垂向不同分层的32种元素进行测量,并通过归一法和百分标准法对测量结果进行分析,研究了药泉山矿泥区土壤不同层的元素变化趋势及垂向波动变化。结果表明,矿泥中含量达到检出限的20种元素中,硅、钾、钛、钒、铬、硼、锂7种元素成先升后降趋势;铝、铁、钠、钙、磷、镁、钡、锰、锶、钴、铜、镍、锌13种元素成先降后升趋势;矿泥中各元素含量垂向波动变化从大到小依次为,钙、锶、锰、磷、钡、镁、铝、硅、硼、镍、铁、钴、钒、锌、锂、铬、铜、钛、钾、钠。可见,药泉山矿泥区矿泥元素垂向变化趋势明显,不同层之间的元素含量差异较大,表层(0~20 cm)和第二层(20~40 cm)元素含量变化最为显著。

In order to study the vertical variation trend of the elements in the volcanic mud in the Yaoquan mountain slime area of Wudalianchi,32 elements in different vertical layers of the volcanic mud in the area were measured by ICP-OES,and the results were analyzed by the method of normalization and percentage standard.The element variation trend and vertical fluctuation change in different layers of the soil in the area were studied.The results show that among the 20 elements that reach the detection limit,7 elements of silicon,potassium,titanium,vanadium,chromium,boron and lithium increase first and then decrease;13 elements of aluminum,iron,sodium,calcium,phosphorus,magnesium,barium,manganese,strontium,cobalt,copper,nickel and zinc decrease first and then increase;the vertical fluctuation of the contents of various elements in the slime is from large to small,followed by calcium,strontium,manganese,phosphorus,barium and magnesium,aluminum,silicon,boron,nickel,iron,cobalt,vanadium,zinc,lithium,chromium,copper,titanium,potassium,sodium.It can be seen that the vertical change trend of mineral mud elements in yaoquanshan mine mud area is obvious,the difference of element content among different layers is large,and the most significant change of element content is in the surface layer(0~20 cm)and the second layer(20~40 cm).
