摘要：

This bauxite deposit lies within the Maranhao basin and appears to have developed in late Tertiary and early Quaternary sediments. The elements (F, S, Cl, Sc, V, Ga, Se, Nb, Cd, In, La, Sm,Gd, Tb, Ho, Er, Tm, Yb, Pb, U) with concentrations similar to those in the earth's crust number approximately the same as those (Cr, Co, Ni, Cu, Zn, Br, Rb, Sr, Y, Ag, Cs, Ba, Ce, Pr, Nd, Eu) whose levels are depleted. Enriched elements (B, As, Zr, Mo, Sn, Sb, I, Hf, Th, Bi) include those having refractory oxides and those exhibiting biological affinity. -from Authors
