Thermal Model of Changes in the Thickness of the Continental Lithosphere over Time

The results of numerical modeling for the increase and decrease in the thickness of a highly viscous continental lithosphere under whole-mantle convection on a time interval of 3.5 Ga were considered. It was found that the initial period of lithosphere growth took about 1.1 Ga, followed by a period...

Summary:The results of numerical modeling for the increase and decrease in the thickness of a highly viscous continental lithosphere under whole-mantle convection on a time interval of 3.5 Ga were considered. It was found that the initial period of lithosphere growth took about 1.1 Ga, followed by a period of its slow thinning because of gradual heating of the mantle by several hundred degrees from the thermal insulation effect of the lithosphere.
