Major element and isotopic studies on the James Run/Port Deposit association, Maryland: tectonic analogues and Taconic deformation
… Run metavolcanics bear a fault relation with the Wissahickon metasediments of the Glenarm terrane of the northeastern Maryland Piedmont, USA. Bulk chemical and mineralogical data classify the meta-igneous rocks as a bimodal tholeiite-dacite/tonalite suite with trondhjemitic affinities and indicate …
