Related to epeirogenic: diastrophism


Movements which affect large tracts of the earth's crust.



slow secular uplifts and/or subsidences of vast areas of the crust that do not alter the crust’s structure. The term “epeirogeny” was introduced in 1890 by the American geologist G. Gilbert in contrast to the term “orogeny.” In the broad sense, epeirogeny corresponds to the concept of oscillatory movements of the earth’s crust (seeOSCILLATORY MOVEMENTS OF THE EARTHSCRUST).
