Mantle Composition Insights
The mantle consists of two main layers: the upper and lower mantle, each with distinct compositions and properties. The upper mantle, rich in mafic minerals like olivine and pyroxene, is better understood due to surface samples, while the lower mantle's complex makeup remains largely a mystery. Understanding these layers is crucial, as they influence the Earth's geology and behavior under extreme conditions.In this clip
