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,Fe,Mn,Ni are usually higher than those of the later,but their abundances of Rb,Ca,Sr,Ba are lower than those of the later.This correspounds well with the geochemical exploration anomaly in the study areas.
