This file should be accompanied by brooks-west.gdb-ValidationErrors.html, brooks-west.gdb-vFgdcMetadata.txt, and brooks-west.gdb-vFgdcMetadataErrors.txt, all in the same directory.

This database is LEVEL 3 COMPLIANT, pending completion of a peer-reviewed Geologic Names report that includes identification of any suggested modifications to Geolex. The database-level FGDC metadata are formally correct. The metadata record should be examined by a human to verify that it is meaningful.

30 --- Note on mylonite ages. --- --- The original publication did not assign an age to these deformation-related metamorphic rocks. The age reported here, Permian-Ordovician, represents the range between the age of the original protolith rocks (Cape Elizabeth and Scarboro Formations) and superimposed mylonitic deformation. 05-01 DMUUnit1 --- --- --- --- DAS1 --- --- DMU12952 ---
31 whc Whitten Hill Complex Whitten Hill Complex Permian-Ordovician A wide variety of generally fine-grained rock types is present over a relatively short distance across strike in Halfmoon Stream, in the southwest corner of the quadrangle. Rock types include light gray mica-bearing quartzite; light to medium gray calc-silicate granofels interlayered with subordinate amounts of biotite granofels; rusty-weathering, dark gray sulfidic granofels (Photo 5); and rare hornblende gneiss. Outcrop exposure to the northeast of this stream is inadequate to map these various rock types separately along strike. In the central and eastern portion of the quadrangle the unit is thinner and is dominated by deeply rusty-weathering, dark gray, sulfidic, graphitic, quartz-rich granofels and minor schist. The lithologic variability within this unit is displayed in outcrops along Halfmoon Stream. Outcrops of the rusty-weathering granofels in the central portion of the quadrangle are found near the Route 139 crossing of the Belfast and Moosehead Lake Railroad. 05-01-01 DMUUnit2 whc 504 153,179,255 pattern-335 DAS1 Deformation-related metamorphic rock High: GeoMat DMU5792 156,177,255
32 rcm Ray Corner Mylonite Suite (Pollock, 2018) Ray Corner Mylonite Suite Permian-Ordovician This bedrock unit is a highly deformed structural complex, characterized by strongly sheared rocks which contain a steeply dipping mylonitic foliation. While there is lithologic variability, the most common rock type is a medium to dark gray, aphanitic to fine-grained, mylonitic gneiss. The very thin layering in the gneiss, defined by alternating shades of gray, typically ranges from 0.2 to 2 cm in thickness. Locally, the mylonite is cut by narrow veins of pseudotachylyte (< 2 cm), some of which are parallel to the mylonitic foliation, and some of which cut across it (Photo 8). In addition, some exposures are cut by complex networks of very thin (usually < 3 mm) white, chalky-weathering veins that cut across all other structural fabrics (Photo 6). Locally, these veins are much thicker (up to 30 cm across) and represent a lithified fault breccia, containing abundant clasts of mylonite with no obvious preferred orientation. Rocks along the northwestern margin of this unit are protomylonitic and contain abundant muscovite fish that show a dextral or right-lateral sense of shear. Rocks along the southeastern margin of the unit are also protomylonitic, but have a different composition, commonly containing thin, fine-grained calc-silicate layers. There are accessible exposures of the unit in a series of low outcrops along the south side of County Road, approximately 500 meters west of Ray Corner. 05-01-02 DMUUnit2 rcm 203 222,204,255 pattern-334 DAS1 Deformation-related metamorphic rock High: GeoMat DMU5808 223,201,255
33 bpm Basin Pond Mylonite Basin Pond Mylonite of the Ray Corner Mylonite Suite Permian-Ordovician Medium gray to dark gray, fine-grained mylonitic to ultramylonitic gneiss that commonly is interlayered with medium gray, fine-grained biotite granofels with subordinate amounts of calc-silicate granofels and rusty-weathering phyllite. Thin (< 2 cm) discordant pseudotachylyte veins and/or zones of light gray lithified fault breccia and cataclasite are present locally. This unit is exposed in large road cuts on Route 7, approximately 800 meters north of Brooks village (Route 139 intersection). 05-01-02-01 DMUUnit3 bpm 405 179,153,255 pattern-333 DAS1 Deformation-related metamorphic rock High: GeoMat DMU5805 191,145,255

35 my Mylonite Mylonite Permian-Ordovician Light to medium gray, fine-grained to medium-grained, porphyroclastic mylonite (Photo 7). Porphyroclasts are most commonly feldspar, but carbonate-rich clasts are abundant locally. Layering in the mylonites, where present, is generally on the order of 0.2 to 2 cm in thickness. The mylonitic foliation is steeply dipping. Kinematic indicators consistently show a dextral or right-lateral sense of shear. These mylonites are coincident with the Hill 806 fault originally mapped by Pankiwskyj (1996). There are good exposures of this unit approximately 300 meters north-northwest of Styles Cemetery near the east edge of the map. 05-01-04 DMUUnit2 my 6 255,128,255 pattern-335 DAS1 Deformation-related metamorphic rock High: GeoMat DMU5795 255,135,255
