Usage: geology; technical

Examples

• Epeirogenic movements shaped the stable interior of the North American continent over millions of years.
• The geologist studied epeirogenic processes to understand how vast plains were formed.
• Epeirogenic uplift gradually raised the elevation of the continental platform.
• Unlike orogenic mountain building, epeirogenic activity produces gentle, broad deformation.
• The epeirogenic subsidence of the basin allowed sediments to accumulate over time.
