These will anlisessero carried through for the laboratory of electronic microscopy Observe occurrence of the species of the lixeira next the diggings to the region decangas that one becomes of easy distribution and identification. The referring work meets in execution, but with the partial one of results, in permitemconcluirque the biogeoqumica prospection, can be used as half efficient deamostragem in substitution to the prospection geochemistry of ground. Moreover, had ‘ ‘ American Curatella L’ ‘ to present ampladistribuio, occurring of this Mexico until the south of the state of SoPaulo, makes possible that the same one, can be used in futurostrabalhos of biogeoqumica prospection throughout all America doSul. Simplicity and the low cost in the collection of the plant (leves) represent financial economy and of time in the campaigns prospectivaspara gold, therefore it represents low cost to delimit areas deocorrncia of gold concentration in any region where lixeirapossa to be showed..
