Mafic magmatic enclaves in flow-banded rhyolite, western Zarembo Island. The ovoid shape and preferred orientation of the inclusions suggest that the mafic enclaves were transported as plastic droplets of magma in the rhyolite flow. White specks on the outcrop are barnacles. Hammer for scale.

Plot of alkali oxides versus SiO2 (in wt.%) comparing magma compositions represented in the Zarembo Island volcanic suite and in the Deer Island – Etolin Island intrusive complex. Descrimination style from LeBas et al. (1986). Rocks from the Zarembo Island – Burnett Inlet volcanic–plutonic complex define a generally bimodal suite with a gap in silica concentrations at 60–65 wt.%.

(A) through (N). Photographs of outcrops and polished rock slabs from mineral occurrences of the Alexander Triassic metallogenic belt. A. Pervasive orange-black, hydrothermal iron and manganese alteration of the Nehenta limestone and carbonate debris flows in Nehenta Bay, southern Gravina Island. Note the pod-shaped occurrence of bladed white barite and minor sulfides to the right of the hammer. B. Altered gabbroic sill beneath barite-sulfide pod. Berg 17 occurrence, Sylburn peninsula, Annette Island. C. Massive vein of pink and white barite cutting clastic sedimentary rocks and limestone at the top of the Keku rhyolite. Note the botryoidal banding defined by fine galena. Northeastern shoreline of the Cornwallis peninsula on Kuiu Island, Keku Strait area, central southeastern Alaska. D. Mineralized Cornwallis limestone breccia from the Kuiu Zinc deposit on the Cornwallis peninsula. The matrix to the clast is composed of sphalerite, galena, and Fe-Mn carbonate. E. Mineralized limestone from the top of the open cut at the Taylor Creek occurrence, Duncan Canal, central southeastern Alaska. The sample contains pyrite, sphalerite, galena, and tetrahedrite in irregular veins and as replacements of limestone, with a white dolomite gangue. F. Nodular pyrite in limestone near the Taylor Creek open cut. This texture is interpreted to be the result of early diagenetic replacement of carbonate mud. G. Barite-galena–rich material from the Castle Island barite mine in the Duncan Canal area, central southeastern Alaska. H. Glacier Creek (Main) deposit in the Mount Henry Clay area, northern southeastern Alaska. The central, orange-white zone consists of quartz-sericite-carbonate schist with lenses of massive barite and lesser sulfides. The outcrop above and below consists of massive and pillowed basalt flows. I. Barite-sulfide lens at the Upper Cap occurrence in the Mount Henry Clay area, northern southeastern Alaska. Rocks overlying the lens are massive basalt flows. J. South side of Windy Peak at the Windy Craggy deposit in northwestern British Columbia. Light and dark subhorizontal layering comprises intercalated mafic sills and flows with calcareous black argillites. K. Typical pyritic massive sulfide with minor pyrrhotite and chalcopyrite in a quartz-carbonate gangue, from the north crosscut of the Windy Craggy deposit in northwestern British Columbia. The black elongate inclusion in the lower right part of the sample is an argillite clast. L. Pyrite- and sphalerite-rich massive sulfide from a boulder found at the Mount Henry Clay (Boulderado) occurrence in northern southeastern Alaska. M. Massive sulfide lens at the Frenchie deposit on Zarembo Island, central southeastern Alaska. Timbers in the adit are ~2 m high and are holding up a hanging wall of graphitic quartz-sericite schist. N. Samples from the Frenchie deposit. Left sample is dominantly pyritic with some chalcopyrite and characterizes the majority of the sulfide lens. The center sample is more sphalerite and galena rich; the right sample has significant barite typical of the distal portion of the lens.
