摘要

铀矿床存在于各种地质环境中,因此几乎存在于所有地质阶段:高度变质、变质、变质、表层和火山至沉积围岩。在本研究中,采用片断回归和蒙特卡罗模拟法,在 90% 的置信水平上预测了巴格哈克矿区(作为案例研究)的铀含量。为此,对研究区域的 151 个地球化学样本进行了分析,稀土元素、钍和钇因与铀的相关性最高而被选为独立参数。得出了一个估算铀含量的等式,显示出与实际数据的高度相关性(86%)。根据最终模型,生成了 2,200 个铀的随机数据点,平均值与实际值仅相差 0.1(浓度的对数单位)。这表明该模型模拟实际值的准确性很高。根据密度函数,模拟值与实际值非常吻合,证实了模型的有效性。在这一区域,根据对数计算,铀的置信区间为 1.8 至 2.6。最后,根据独立参数对预测铀含量的影响,对其进行了优先排序。这项研究可被视为评估和预测不同地区铀浓度的实用工具,有助于改善矿产资源管理。

Possibility of Monte Carlo simulation for predicting radioactivity in the Baghak, NE Iran

Possibility of Monte Carlo simulation for predicting radioactivity in the Baghak, NE Iran

Uranium deposits are found in various geological environments; therefore, these exist in almost all geological phases: in high degree of metamorphic, metasomatic, Metamorphism, Surficial and Volcanic to Sedimentary perimeters. In this study, the amount of uranium in the Baghak mine (as a case study) was predicted using piecewise regression and Monte Carlo simulation at a 90% confidence level. To this end, 151 geochemical samples from the study area were analyzed, with rare earth elements, thorium, and yttrium selected as independent parameters due to their highest correlation with uranium. An equation was derived for estimating uranium levels, showing a high correlation (86%) with actual data. Based on the final model, 2,200 random data points for uranium were generated, with the mean differing by only 0.1 (logarithmic unit of concentration) from actual values. This indicates the model’s high accuracy in simulating real values. The simulated values closely matched actual values based on the density function, confirming the model’s validity. In this area, the confidence interval for uranium is from 1.8 to 2.6 based on logarithmic calculations. Finally, the independent parameters were prioritized based on their impact on predicting uranium levels. This research could be considered a practical tool for assessing and predicting uranium concentrations in various regions and could aid in improving mineral resource management.

期刊介绍: Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth: Water and soil contamination caused by waste management and disposal practices Environmental problems associated with transportation by land, air, or water Geological processes that may impact biosystems or humans Man-made or naturally occurring geological or hydrological hazards Environmental problems associated with the recovery of materials from the earth Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials Management of environmental data and information in data banks and information systems Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
