Silicon is an element throughout our crust. Mass calculation accounts for 27.7% of the crust, second only to oxygen, and is the second most abundant element in our crust. Si is a fusible component, and Si tends to enter the melt during the melting process. Therefore, during the partial melting of the crust or mantle, Si is easily enriched in the melt, which eventually makes the crust richer in Si.
