Field guide to the Mesozoic accretionary complex along Turnagain Arm and Kachemak Bay, south-central Alaska
Turnagain Arm, just east of Anchorage, provides a readily accessible, world-class cross section through a Mesozoic accretionary wedge. Nearly continuous exposures along the Seward Highway, the Alaska Railroad, and the shoreline of Turnagain Arm display the two main constituent units of the Chugach terrane: the McHugh Complex and Valdez Group. In this paper we describe seven bedrock geology stops a

Link between ridge subduction and gold mineralization in southern Alaska
40Ar/39Ar geochronology reveals that turbidite-hosted gold deposits in the southern Alaska accretionary prism are the same age as nearby near-trench plutons. These early Tertiary plutons and gold lodes formed above a slab window during subduction of an oceanic spreading center. Ridge subduction is a previously unrecognized tectonic process for the generation of lode gold.

Earthquakes in Alaska
Earthquake risk is high in much of the southern half of Alaska, but it is not the same everywhere. This map shows the overall geologic setting in Alaska that produces earthquakes. The Pacific plate (darker blue) is sliding northwestward past southeastern Alaska and then dives beneath the North American plate (light blue, green, and brown) in southern Alaska, the Alaska Peninsula, and the Aleutian

Possible active fault traces on or near the Castle Mountain fault between Houston and the Hatcher Pass Road: A section in RGeologic studies in Alaska by the U.S. Geological Survey, 1993
The Castle Mountain fault is one of several major east-northeast-striking faults in southern Alaska, and it has had historical seismicity and Holocene surface faulting. The Castle Mountain fault was delineated on a regional scale by Detterman and others (1974, 1976), who divided it into two physiographic segments. Mapping in a 30-km-long region between the two segments (from Houston to the Hatcher

Timing of early Tertiary ridge subduction in southern Alaska: A section in Geologic studies in Alaska by the U.S. Geological Survey, 1992
We present a new compilation of 158 isotopic ages from Tertiary plutons that intrude the accretionary prism (Chugach-Prince William composite terrane) of southern Alaska. Two broad plutonic age groups are present: Paleocene to Eocene (the Sanak-Baranof plutonic belt), and Oligocene to Miocene. Plutons of the Sanak-Baranof belt are broadly coeval with magmatism along the axis of an Andean-type arc

Structural evolution of the Chugach-Prince William terrane at the hinge of the orocline in Prince William Sound, and implications for ore deposits
The Chugach-Prince William terrane is a Mesozoic through Tertiary accretionary complex that lies along coastal southern and southeastern Alaska. In Prince William Sound, the regional structural fabric bends about 90°, forming an orocline. Rocks at the hinge of the orocline consist of turbidites, conglomerate, and minor volcanic rocks and limestone. The structural geology in the hinge region define

Tilting, burial, and uplift of the Guadalupe Igneous Complex, Sierra Nevada, California
It is often incorrectly assumed that plutons have a relatively uneventful structural history after emplacement. The 151 Ma Guadalupe Igneous Complex (GIC) in the Foothills Terrane, California, was involved in three post-emplacement events: (1) ∼30° of southwestside-up tilting during ductile regional faulting and contraction, (2) burial of the pluton from ∼4 to 12 km during crustal thickening of th
