| 摘 要： | Background ＆ objective： Medical geology is a discipline of environmental health dealing with the impacts of geological relationship between loess deposits and certain endemic diseases such as esophagus cancer. This article deals with loess deposits with medical geology aspect toward diagnosis and prognosis. Materials ＆ Methods： In this study sampling from loess deposits from East towards West has been done. Collected samples have been undergone X-ray diffraction （XRD）, scanning electron microscopy （SEM） and Energy dispersive X-ray analysis （EDAX） for determination of minerals, surface morphology of minerals and chemical analysis for further studies, respectively. Results： In mineralogical studies dominated minerals are quartz, feldspar and calcite. Clay minerals are illite and chlorite, which are about 9.3%. The amount of quartz is variable from 56.3 to 45.4. The grains sizes are decreasing from northeast to southwest. Chemical analysis showed that loess deposits contain Si, Al, K and Ca, which are related to the presence of quartz, feldspar, calcite, illite and chlorite minerals. Conclusions： According to medical geology evidence, loess deposits of Gloestan Province could be closely related to the incidence of esophagus cancer due to effect of clay minerals on biochemical cycle, direct relation of grain size with the incidence of esophagus cancer and chemical composition of loess deposit for its high silica are also taken into consideration. As the esophagus cancer belt coincides with the loess deposits belt of the world.
