Geochemistry of the Catheart Mountain Porphyry Copper Deposit, Maine
Maine Geological S urvey Studies in Maine Geology: Volume 4 1989 Geochemistry of the Catheart Mountain Porphyry Copper Deposit, Maine Robert A. Ayuso U.S. Geological Survey Reston, Virginia 22092 ABSTRACT The Ordovician Catheart Mountain pluton is the best example ofa porphyry copper system in the New England Appalachians. It intrudes the Ordovician Attean quartz monzonite in the Proterozoic Chain Lakes massif. The pluton consists of equigranular granodiorite intruded by porphyritic dikes of granite and granodiorite which contain up to 4% sulfides (pyrite, chalcopyrite, and molybdenite). The equigranular host rocks and the porphyritic dikes are generally chemically similar, showing scattered compositional variations which reflect changes imposed on the pluton during crystallization and hydrothermal alteration. Most rocks are hydrated, containing high C02 and high S. The most intensely altered parts of the pluton are potassic (up to 6.9 wt % KiO) and highly mineralized, especially with Cu (up to 3900 ppm), but also with Mo (up to 320 ppm). The host granodiorite and porphyritic dikes are depleted in Ca, Na, Fe2+ and Sr as a function of increasing Cu; the sulfide-rich rocks are enriched in Rb and they have high Fe3+/Fe2+, K/Na, and Rb/Sr values. Abundances and ratios of the highly-charged cations (e.g. Zr, Hf, Ta, and Th) in the Catheart Mountain pluton resemble those in the Devonian granodiorites in the northern Maine plutonic belt. Abundances and ratios of the highly-charged cations in the Sally Mountain pluton, a nearby body also containing Cu and Mo mineralization, differ significantly from those in the Catheart Mountain pluton suggesting that the two plutons are not comagmatic. -

It serves particularly two of California's most important industries, aprieulture and construction. In Bulletin 163 the author, W. p]. Xev Phinek, a member of the staff of the Division of Mines, has prepared a comprehensive treatise cover- ing all phases of the subject : history of the industry, geologic occurrence and origin of tlie minoi-al, mining, i)rocessing and marketing of the com- modity. Specific g3'psum i)roperties Avere examined and mapped. The report is profusely illustrated by maps, charts and photographs. In the preparation of the report it was necessary for the author to make field investigations, laboratory and library studies, and to determine how the mineral is used in industry as Avell as how it occurs in nature and how it is mined. -

Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. iu.S.G.S., Menlo Park, California 94025 2U.S.G.S., University of Washington, AJ-20, Seattle, Washington 98195 3SWMD, King County Department of Public Works, Seattle, Washington, 98104 ^Department of Geology, Western Washington University, Bellingham, Washington 98225 INTRODUCTION The Mount Baker 30- by 60-minute quadrangle encompasses rocks and structures that represent the essence of North Cascade geology. The quadrangle is mostly rugged and remote and includes much of the North Cascade National Park and several dedicated Wilderness areas managed by the U.S. Forest Service. Geologic exploration has been slow and difficult. In 1858 George Gibbs (1874) ascended the Skagit River part way to begin the geographic and geologic exploration of the North Cascades. In 1901, Reginald Daly (1912) surveyed the 49th parallel along the Canadian side of the border, and George Smith and Frank Calkins (1904) surveyed the United States' side. Daly's exhaustive report was the first attempt to synthesize what has become an extremely complicated geologic story.
