| 摘 要： | Biogeochemical investigation of Tamarix aphylla,a plant species, of the Las-bela area has been made.This area mainly consists of ophiolites associated with sed-imentary rocks of Jurassic and Cretaceous age .Quantitative estimations of important biogenic trace elements such as Fe,Mn,Pb,Zn,Cu,Cr,Ni, and Co have been carried out .Anomalous concentrations of these elements in plant species of certain regions can be used to locate possible occurrences of ore deposits in the area.The comparative strdy also reveals appreciable variations in the composition of trace elements in plants.The possible causes of variation in the constitrents of Tamarix aphylla from different localities have been discussed in the light of bed rock nature, mo-bility of element and average abundance in the plant.

| Abstract: | Biogeochemical investigation ofTamarix aphylla, a plant species, of the Lasbela area has been made. This area mainly consists of ophiolites associated with sedimentary
rocks of Jurassic and Cretaceous age. Quantitative estimations of important biogenic trace elements such as Fe, Mn, Pb, Zn,
Cu, Cr, Ni, and Co have been carried out. Anomalous concentrations of these elements in plant species of certain regions can
be used to locate possible occurrences of ore deposits in the area.
The comparative study also reveals appreciable variations in the composition of trace elements in plants. The possible causes
of variation in the constituents of ash ofTamarix aphylla from different localities have been discussed in the light of bed rock nature, mobility of element and average abundance
in the plant. |
