Paragenetic and geochemical differences of mineral deposits between the Dinaric lherzolite and harzburgite-dunite ophiolite belts
Published in Adam Piestrzyński, Mineral Deposits at the Beginning of the 21st Century, 2001
Most parts of cumulates and non-cumulates were affected by low grade metamorphism. Gabbros, diabases and spilites from Mts. Kozara, Ozren, Konjuh and Višegrad are crosscut by numerous thin veinlets and veins filled mainly by zeolites: sodic (natrolite, analcite), Na-Ca zeolites (thomsonite), calcic zeolites (scolecite-desmine-stilbite, laumontite, and calcic-boric zeolite (datolite). These minerals are accompanied by prehnite, albite, epidote, clinozoisite, cal cite and serpentine.

The experimental study emphasized the high reliability of zeolites for soil remediation, as they decrease metal concentrations, even when used in a complex multi-component system. The results of the experimental study showed not only the efficiency of the zeolite mineralogical species used (thomsonite-mesolite-clinoptilolite), but also the affinity of these mineral species towards the investigated elements, with the following selectivity series: Cu > Mn > Fe > Zn.

In conclusion, Jatropha curcas L seed oil has been found to be non-edible because the physico-chemical characteristics do not comply with the specification of world health organization for edible oils. The higher oil content and non-editability of jatropha oil supports using it as biodiesel production resource. The biodiesel has been synthesized successfully via natural zeolite (96.6% Thomsonite and dicalcium 3.4%) because more of FFA trans-esterified to FAME.
