Solar radiation may have an impact on Earth's deep interior, according to a collaborative study by researchers from China and Romania. According to the researchers, solar radiation varies with latitude, creating temperature gradients on the sea surface that influence the distribution of marine life. This process significantly affects the redox state of arc magma. They examined tiny melt inclusions within olivine minerals and bulk rock data to determine the redox state of arc magma. Understanding the spatial and temporal distribution of redox state at global subduction zones has significant implications for predicting the locations and availability of these critical resources.
