新疆喀拉通克铜镍矿区植物地球化学特征及找矿有效植物和元素的选择
Characteristics of phytogeochemistry and prospecting choices of effective plants and elements in Kalatongke Cu-Ni ore field,Xinjiang
摘要
Abstract
The vegetation in Kalatongke Cu-Ni ore field belongs to a type of soil gravel hungriness one.Seriphi-dium terrae-albae(Krasch.)Poljak.is a dominant floral community and Nanophyton erinaceum(Pall.)Bunge and Artemisia frigida Willd.,etc.major associated plants in the ore field.The main geochemical type of plants in this region are rich in Ca and Mg,but poor in K and Na.From the region background area,the mining area to the upper part of the deposit,contents of ore-forming elements and associated elements increase gradually and probability distribution curve changes from single peak normal distribution to multi peak distribution in plant community and most plant species.Distribution of elements in different plant species is uneven.Contents of Cu and Ni in plants have positive correlation relationships with most elements in the background area,but their pos-itive correlation degree with other elements decreases and even appears negative correlation in the upper part of the deposit.Plant absorption of elements has selective and shielding effects.When the accumulation coefficient of elements is large,their contrast decreases,but the accumulation coefficient of elements is relatively small, their contrast increases in plants.In this ore field,Seriphidium terrae-albae(Krasch.)Poljak.,Nanophyton eri-naceum(Pall.)Bunge and Artemisia frigida Willd.,etc.can be used as important sampling media and Cera-toides latens (J.F.Gmel.)Reveal &N.H.Holmgren and Ceratocarpus arenarius L.,etc.can be used as auxilia-ry sampling medium in phytogeochemistry prospecting.Cu,Ni and Ag can be used as preferred indicator ele-ments,Pb,As,Bi,Co and Au can be used as general indicator elements and Zn,Cr,Mn and Mo should not be used as indicator elements.关键词
