Geochemical And Mineralogical Studies Of Sedimentary Alluviums - A Case Study In The City Of Omidiyeh In The Southwest Of Iran.
Main Article Content
Abstract
Alluvial fans are cone-shaped deposits that are known to be important deposits of minerals and water resources. An accurate knowledge of alluvial deposits not only provides access to many natural resources, but also prevents various environmental risks, including the transfer of various toxic elements. To date, many methods have been introduced for the investigation of alluvial deposits, but this study presents for the first time geochemical methods that can significantly reduce costs and investigation time in areas associated with alluvial deposits.
This study was carried out in the southwest of Iran and near the city of Omidiye on 120 sediment samples from various alluvial conifers. In this study, the samples collected through petrographic and geochemical studies were carefully analyzed, and in addition to determining the major and minor elements in these samples, the primary origin of the sediments, the primary tectonic position of these sediments, and the nature of the constituents were also determined for the first time using geochemical data. In addition to the geochemical investigations, detailed hydrochemical studies were carried out to determine the relationship between the properties of the groundwater and the type of sediments on the surface. These studies can be seen as a model for similar studies around the world.
