摘要：During feld work in 2014, we investigated a suite of igneous intrusions in south-eastern Greenland between 65° and67°N. Many of the intrusions show widespread evidence forjuxtaposition of different magmas in the liquid state and subsequent mixing, mingling and hybridisation. Here we present feld evidence for these processes from three areas thatdiffer in age and geological setting. We discuss the signifcance of mingling, mixing and hybridisation features in thefeld area, motivated by their abundance in the area, the morphological variation between intrusions that were emplacedat different crustal levels, the implications for magma genesisin collisional and rif settings, and the implications for theinterior dynamics of igneous bodies.
