- Abstract
- The analysis of the geochemical characteristics of the sediments of Lake Porthibol, located in the northern part of the Murmansk region, revealed elevated concentrations of Mo, U, Th, REEs, and other elements compared to the upper crust. For Mo, the highest concentration coefficient was established at 92.5. Additionally, the studied sediments showed 39–86 times exceeding concentrations of Mo compared to the background levels of the element in the sediments of the lakes of Karelia. Age assessment of the sediment core from Lake Porthibol indicated that the upper 9 cm of sediments formed over 165 years, with sedimentation rates varying from 0.6: mm/year. Considering that the highest concentrations of Mo (up to 137.1 mg/kg) in the sediment core from Lake Porthibol were found in deeper layers, the anthropogenic influence of the last three centuries could not have affected its elevated level. It is suggested that the main source of Mo in the sediments of the studied water body is the rocks of the Litsevsky ore district, where, in addition to the primary uranium mineralization, elevated concentrations of Mo (up to 600 mg/kg) have been established.
