Abstarct: This thesis is an idea indicating that there's a logic relation between the Bauxite thickness variation and upright laxyers and constituents in Bauxite. If so, it would be predicted to estimate the mineral trend in the unexplored regions. Consequently, a model can be presented to prevent the unnecessary exploration excavations. Furthermore, designing and mine inclination determination as well as the appropriate degree of purity in daily extraction planning may be taken into attention. To do these, all information and data extracted from Jajarm Bauxite included [collar sheet data file (geographic coordinate,DIP, Azimuth and their deeps,step of digging, type of borehole and ...)geologic sheet data file(boreholename,litlogy,sample number of each deep, litology changing) and assay sheet data file,(borehole name litology sample number of each deep,refer to our assay,assay data and ...)] have been studied. The amount of the Bauxite components such as Al2O3, SiO2, Fe2O3, TiO2, CaO, MgO, K2O and those elements lacking the analytical information are estimated. Investigation showed that the estimation of Fe2O3, TiO2, CaO, and MgO is possible but this is not applicable for K2O. Consequently, data file of the above mentioned components has been taken into account as the main file. Relation between the different components purity and hard bauxite laxyer in all regions is studied and no meaningful relationship was detected. Furthermore separating the mineral in two profile with up and down thickness, repeatedly no relationship was found. Finding a relation between purity and thickness in various profiles had no result. Contrary to what we expected, there is no meaningful relation between the thickness and different components in the Bauxite. So the hypothesis of the relation between Bauxite thickness various laxyers in the hanging wall of the mineral was rejected.
