ABSTRACT: The method of biogeochemical prospection, with aim of exploring unknown mine ores, baseson the principle of chemical analysis of plant samples, for the purpose that are called indicator,accumulator and hyperaccumulator. Accumulator plants have the ability to take up large amountsof metals from soils. Because of this , three species ( Alyssum murale Waldst & Kit, Alyssumfloribundum Boiss & Ball, Alyssum peltarioides, Boiss, subsp, virgatifarme (Ngar)) of Alyssum(in leaves ,twigs and flowers) and soil samples were collected from 42 sites in the FındıkpınarıErdemli/Mersin) area, were chemical analysed for their Ni, Co, Fe, Cu, Mn ve Zn contents .Theseelements of samples were determined by flame atomic absorpsiyon spectrofotometer. Data for thestatistical significance of plant/soil relationship for Ni are summarised. The A. murale (n: 20,r: 0.8879 and for extreme Ni , n: 4, r: 0.9873, P<0.05, %95 , in flowers) species for Ni showedhighly significant, (P<0.01, %99 with reliability.) relationships. This plant species is apparentlygood accumulator for Ni element and could be succesfully used for the further biogeochemicalprospecting and environmental monitoring.
