چکیده انگلیسی
⺠New radiogenic isotope data are presented for intrusive rocks of the Midcontinent Rift. ⺠Negative ÉNdT are consistent with contamination of a plume-related source by older crustal material. ⺠Contamination by subcontinental lithospheric mantle is thought to have occurred in all units. ⺠Selective contamination by host country rocks during emplacement has occurred in some units.
