    Description:
      Abstract:
This digital map database has been prepared from the published geologic map of the Skykomish River 30- by 60-minute quadrangle by the senior author.  Together with the accompanying text files as PDF, it provides information on the geologic structure and stratigraphy of the area covered.  The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S.  Geological Survey.  The authors mapped most of the bedrock geology at 1:100,000 scale, but compiled Quaternary units at 1:24,000  scale.  The Quaternary contacts and structural data have been much simplified for the 1:100,000-scale map and database. The spatial resolution (scale) of the database is 1:100,000 or smaller.
From the eastern-most edges of suburban Seattle, the Skykomish River quadrangle stretches east across the low rolling hills and broad river valleys of the Puget Lowland, across the forested foothills of the North Cascades, and across high meadowlands to the bare rock peaks of the Cascade crest.  The Straight Creek Fault, a major Pacific Northwest structure which almost bisects the quadrangle, mostly separates unmetamorphosed and low-grade metamorphic Paleozoic and Mesozoic oceanic rocks on the west from medium- to high-grade metamorphic rocks on the east. Within the quadrangle the lower grade rocks are mostly Mesozoic melange units. To the east, the higher-grade terrane is mostly the Chiwaukum Schist and related gneisses of the Nason terrane and invading mid-Cretaceous stitching plutons. The Early Cretaceous Easton Metamorphic Suite crops out on both sides of the Straight Creek fault and records it's dextral displacement.  On the south margin of the quadrangle, the fault separates the lower Eocene Swauk Formation on the east from the upper Eocene and Oligocene(?) Naches Formation and, farther north, its correlative Barlow Pass Volcanics the west. Stratigraphically equivalent rocks of the Puget Group crop out farther to the west. Rocks of the Cascade magmatic arc are mostly represented by Miocene and Oligocene plutons, including the Grotto, Snoqualmie, and Index batholiths. Alpine river valleys in the quadrangle record multiple advances and retreats of alpine glaciers. Multiple advances of the Cordilleran ice sheet, originating in the mountains of British Columbia, Canada, have left an even more complex sequence of outwash and till along the western mountain front, up these same alpine river valleys, and over the Puget Lowland.
      Purpose:
This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:100,000) scale.  The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults.  In addition, the report contains new information and interpretations about the regional geologic history and framework.  However, the regional scale of this report does not provide sufficient detail for site development purposes.
      Supplemental_Information
DIGITAL COMPILATION- The geologic map information was scanned from a stable ink-on-mylar author compilation at 1:100,000 scale. The scanned digital image was used produce color fill on the Scitex.  The digital image of polygons was vectorized and later edited by R.W. Tabor to produce an ARC/INFO coverage complete with faults etc.  Structural data was hand-digitized from scanned and georeferenced paper copy of the published map.
The original digital compilation was done in version 7.1.1 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991).  Export files for this release were edited and created in 9.1 ARC/INFO.
BASE MAP-The geology of this dataset was mapped on dimensionally stable chronflex prints of the Skykomish River 1:100,000 scale topographic quadrangle.  Although no base map material is included in this dataset, a vectorized version of the base can be downloaded from http://edcftp.cr.usgs.gov/pub/data/DLG/100K/S/. 
SPATIAL RESOLUTION- Uses of this digital geologic map should not violate the spatial resolution of the data.  Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data.  The fact that this database was edited for a scale of 1:100,000 means that higher resolution information is not present in the dataset.  Plotting at scales larger than 1:100,000 will not yield greater real detail, although it may reveal fine- scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

See Yeats (1958a, p. 116-119) for further discussion of that area.  Schistose ultramafite east of Weden Creek  consists of foresterite in mesh of antigorite.  Olivine is locally converted to phlogopite near Tertiary plutons.  In Sultan Basin area Dungan (1974, p. 40-41) describes peridotite hornfels on Red Mountain with assemblage of forsterite-talc-tremolite_chlorite within 2.5 km of contact with Index batholith.  North of quadrangle, ultramafic rocks on strike with this layer are serpentinized cumulus peridotite with relict olivine and orthopyroxene associated locally with layered gabbro (Dungan, 1974, p. 48-62).

          Enumerated_Domain_Value_Definition: PRE-TERTIARY BEDROCK: Tonga Formation of Yeats (1958b) (Late Cretaceous): Phyllite, semischist, schist, and biotite-hornblende gneiss and amphibolite-South of Tye River, mostly graphitic chlorite-sericite-quartz phyllite and high-rank semischist.  To the north, mostly fine-grained graphitic garnet-staurolite-biotite schist, fine-grained biotite-hornblende gneiss, and local metaconglomerate and metaporphyry (fine-grained two-mica gneiss).  In many outcrops from Jack Pass  south, relict bedding and other sedimentary structures in metapelite and metasandstone are prominent despite well-developed penetrative foliation.  Northward and northeastward from Jack Pass, schistose texture and recrystallization increase until recrystallization has produced fine-grained staurolite-garnet-mica schist, and sandstone is recrystallized to fine-grained hornblende-biotite schist and gneiss, locally with randomly oriented or sheaflike poikiloblastic amphibole blades (garbenschiefer); cummingtonite is locally intergrown with hornblende.  Staurolite and garnet are usually porphyroblastic; biotite is porphyroblastic to strongly aligned.  Many of the higher grade rocks show some degree of retrogression: garnet altered to chlorite, staurolite to sericite.  Grade and coarseness of recrystallization increase markedly adjacent to gneissic granodiorite of the Beckler Peak stocks, but hornfelsic textures are not developed.  Rocks are recrystallized to pyroxene hornfels near the Goblin Creek stock.

          Enumerated_Domain_Value_Definition: PRE-TERTIARY BEDROCK: Rocks of the western melange belt (early Tertiary to mid-Cretaceous): Argillite and graywacke-Pervasively sheared, scaley matrix of mostly argillite containing steep-sided, outcrop- to mountain-sized phacoids of purplish, reddish, gray, and black, fine- to coarse-grained and pebbly, lithofeldspathic, volcanolithic, and subquartzose sandstone interbedded with black argillite.  Sandstone has clasts mostly of plagioclase, chert, volcanic rocks, and quartz.  Also abundant are grains of sandstone, siltstone, phyllite, biotite, muscovite, and epidote.  Where more strongly deformed, unstable grains are broken down into anastomosing shear zones or smeared out into indistinct chloritic matrix.  Alteration minerals are calcite, chlorite, sericite, limonite, epidote, and prehnite.  Near Tertiary plutons the rocks have become hornfelsic, commonly with conspicuous biotite.  Sedimentary features such as graded bedding and load casts are locally well preserved.  Unit includes minor chert, polymictic and quartz-pebble conglomerate, and shale-chip breccia; also very minor chert, limestone, metavolcanic rocks, metagabbro, and metatonalite.  Locally cut by greenstone (metadiabase) dikes, Potassium-feldspar-bearing sandstone-Lithologically similar to sandstone of unit TKwa but having 2-20 percent potassium-feldspar clasts and commonly more plagioclase, muscovite, and biotite, Marble-Black to bluish-gray marble and, in part, interbedded chert and shale occurring as steeply dipping pods and lenticular beds.  Thin, green tuffaceous chert beds crop out in marble at Haystack quarry on Proctor Creek, Rocks of the eastern melange belt (early Tertiary to mid-Cretaceous): Chert and metachert-Intensely folded, white to cream or gray, ribbon chert and medium- to fine-grained banded quartzite (metachert); alternating with thin to thick, dark-brown to black layers of calcareous argillite, AND Marble-Lenticular beds and pods of banded, white to grayish, medium- to fine-grained crystalline marble intercalated with metachert and greenstone; in part, shaly laminations or graphitic impurities mark bedding planes.  Silicified replacement masses (Danner, 1966, p. 374; Yeats, 1958a, p. 103).
