1903 R. A. Daly in Amer. Jrnl. Sci. 165 272 (heading) The hypothesis of overhead stoping† by deep-seated magmas. [Note] †A technical mining term meaning to excavate upwards or sideways to remove ore.

1903 R. A. Daly in Bull. U.S. Geol. Surv. No. 209. 102 Magmatic stoping would tend to weaken the earth's crust immediately above the intruding body.

1939 E. B. Bailey & J. Weir Introd. Geol. xlii. 237 On the whole, stoping is probably the most important method of emplacement.

1977 A. Hallam Planet Earth 69/1 Intrusions are emplaced in various ways: for example,..by stoping, a process of gradual movement involving the dislodging of the blocks of country rock and their incorporation—perhaps even assimilation—into the magma.
