چکیده مقاله:

The evaporite chemical sedimentary rocks are rare, but extremely important commercially as the raw materials for the chemical industry. As the name suggests, the evaporites consist of a suite of minerals formed from the evaporation of sea water. Tees area was located of the northern coast of the Oman Sea is located in the northern Chabahar in southern Sistan and Baluchestan province. In this research, evaporite deposits of region by used investigation of geochemical, mineralogical and sedimentological and were taken ۱۵ samples of sediments. The samples analyzed by Geological Survey and Mineral Exploration of Iran. Was calculated Correlation coefficients, cluster and Factor analyses. According to the results of chemical analysis and field observations, the study area is located in Supratidal and are directly affected by sea water. The amount of B and Li in the sediments show significant correlation (average between ۳۳۸.۸ and ۷۳۸.۵) that the correlation is similarly changed. There are also significant differences between the amount of Li and B (average between ۳۹۹.۷ and ۷۳۸.۵), probably affected by coastal erosion and transport margins have been deposited by flowing water and this makes B from earlier upland areas Na and Li stacked in margins of areas. Evaporite minerals that are mainly halite. In study area for all three categories evaporite minerals Contains of chloride, sulfates and carbonates Of course is in low amount. According to cluster and factor analysis, three sources were identified included biogenic, geogenic (continental) and environment.
