Cross-Section Formation of Magnetic Anomalies with Geologic Timescale
This block diagram illustrates the formation of magnetic anomalies for the last four epochs in the earth's magnetic reversal history. The first block diagram shows how mantle upwelling in response to ocean floor spreading produces magmas that form the oceanic crust during the reversed Gilber ...
