A trondhjemite vein in the Sulitjelma Gabbro, Norway, and its implications for the age of the Sulitjelma Ophiolite

Summary The Sulitjelma Gabbro, occurring as a member of the Sulitjelma Ophiolite Complex, and typical of the ophiolite suite in its petrography and geochemistry, is cut by a vein of trondhjemite (plagiogranite). The previous identification of the vein as an offshoot of a continental potassium-rich g...
