山东地区中生代岩浆岩中放射性元素富集规律及其对大地热流异常的指示意义OACSTPCD

In this study,an investigation was conducted to better comprehend the relationship between the concentration of radioactive elements in magmatic rocks and anomalies in terrestrial heat flow.The research focuses on Mesozoic magmatic rocks in Shandong province,analyzing various aspects including rock type,element content,rock formation age,abundance of radioactive thermogenic elements such as Thorium(Th)and Uranium(U),and terrestrial heat flow.The findings indi-cate that syenite exhibits the highest concentration of Th and U elements,while acid and alkaline rocks also display relatively elevated level of these elements.Th and U elements are positively correlated with Silicon(Si)and Potassium(K)elements,but negatively correlated with major elements such as Fe and Mg.Additionally,there is a positive correlation observed with Nb,Ta,Pb,and rare earth elements.Moreover,a certain relationship is established between the abundance of radioactive elements and terrestrial heat flow,but this relationship is also influenced by various factors,including the crustal thickness.This study further reveals the relationship among radioactive elements,magmatic rocks,and geothermal energy.It serves as a valuable reference for the development and utilization of geothermal resources within Shandong province.
