520 3 a| The Coronaca pluton is a late Paleozoic, postkineraatic composite stock which intrudes regionally metamorphosed meta-igneous rocks of the Charlotte belt. Lithologies include granite, quartz syenite, monzonite, monzodiorite, syenite, quartz monzonite, quartz monzodiorite, norite and small, alaskite satellite stocks. Field evidence suggests that contacts are gradational. The Coronaca suite can be divided into three phases on the basis of chemistry and petrology: 1) a felsic phase (granite, quartz syenite); 2) an intermediate phase (quartz monzonite, quartz monzodiorite, syenite, monzonite and monzodiorite) and 3) a mafic phase (norite). Whole-rock chemical analysis of major and trace elements of 30 samples show Si02 concentrations from 46-75 weight percent. Harker plots of CaO, MgO, Fe203, Sr, Rb and Y show curvilinear trends. Aluminum, Ti02, MnO, Zr and the alkalis do not show curvilinear trends, but the plots for these elements are biased by rocks of intermediate composition (53-62 wt. % Si02). Curvilinear trends are enhanced in variation diagrams where major and trace elements are plotted against the Differentiation Index. Modal and normative mineralogical data suggest an I-type parent magma. Petrological and geochemical data suggest that the diverse lithologies are comagmatic. Gravity, magnetic and radioactivity anomalies associated with the pluton suggest that the felsic lithologies of the Coronaca may be a cap, covering a larger, more mafic body at depth.;

Summary	The Coronaca pluton is a late Paleozoic, postkineraatic composite stock which intrudes regionally metamorphosed meta-igneous rocks of the Charlotte belt. Lithologies include granite, quartz syenite, monzonite, monzodiorite, syenite, quartz monzonite, quartz monzodiorite, norite and small, alaskite satellite stocks. Field evidence suggests that contacts are gradational. The Coronaca suite can be divided into three phases on the basis of chemistry and petrology: 1) a felsic phase (granite, quartz syenite); 2) an intermediate phase (quartz monzonite, quartz monzodiorite, syenite, monzonite and monzodiorite) and 3) a mafic phase (norite).
