摘要

油气微渗漏能造成地表植物体内微量元素含量异常。塔北雅克拉和藏北伦坡拉地区油气藏上方地植物与相邻的非油气区地植物相比

具有发育不良

体内微量元素Li

Ni等丰度高

Ba等丰度低的特征。这种异常特征与化探异常有好的对应关系。

Abstract

Hydrocarbon microseepage could result in trace element content anomaly of ground plant.The ground plants above the hydrocarbon pools of Yakela in North Tarim and Lunpola in North Tibeit grow poorer than those of the neighbouring areas

and their abundances of Li

Ni are usually higher than those of the later

but their abundances of Rb

Ba are lower than those of the later.This correspounds well with the geochemical exploration anomaly in the study areas.
