The seacliff exposure at San Simeon, California, contains graphite‐schist blocks in a shale‐matrix, an undocumented lithology within the Franciscan mélange. Thirty graphite‐schist blocks were studied to discover all the varieties in this classic locality of mélange. Based on their mineralogical assemblage and composition, and textural characteristics the graphite‐schists in San Simeon are subdivided into two main types (Type I and II) with two subdivisions each (A and B). Type IA and IIA blocks…

Record of Jurassic mass transport processes through the orogenic cycle : understanding chaotic rock units in the high-pressure Zermatt-Saas ophiolite (Western Alps)

The eclogite facies Zermatt-Saas ophiolite in the Western Alps includes a composite chaotic unit exposed in the Lake Miserin area, in the southern Aosta Valley region. The chaotic unit is

Structure and origin of the gold mineralization in the Nacimiento Block: The Los Burros deposits (Central California)

Abstract The Los Burros gold deposit is located within the Franciscan complex of the Nacimiento block, California. Although this deposit was mined during the late 19th and early 20th centuries, its

Submarine Landslide Deposits in Orogenic Belts

Olistostrome and sedimentary melange are two synonymous genetic terms referring to the “fossil” products of ancient submarine mass‐transport processes exhumed in orogenic belts. Lithology,

Drainage from the Critical Zone: Lithologic Controls on the Persistence and Spatial Extent of Wetted Channels during the Summer Dry Season

In seasonally dry environments, critical zone drainage provides base flow that sustains river ecosystems. The extent of wetted channels and magnitude of base flow throughout the network, however, are



Low-temperature blueschist-facies mafic blocks in the Franciscan melange, San Simeon, California: Field relations, petrology, and counterclockwise P-T paths

Dozens of mafic blueschist blocks are found in the Franciscan melange, which is well exposed along 6+ km of nearly continuous sea cliffs and wave-cut benches near San Simeon, California. Thirty-four

Flow melanges: Numerical modeling and geologic constraints on their origin in the Franciscan subduction complex, California

In northern California, the central belt of the Franciscan subduction complex of late Mesozoic to early Tertiary age is largely a zone of chaotically mixed pelitic-matrix melange. The melange

Distribution and Age of High-Grade Blueschists, Associated Eclogites, and Amphibolites from Oregon and California

Isolated blocks of high-grade blueschist and amphibolite facies metamorphic rocks occur within the Jurassic and Cretaceous eugeosynclinal deposits of the Coast Ranges of southwestern Oregon and

Tectonic contact between the Franciscan Mélange and the Great Valley Sequence—Crustal expression of a Late Mesozoic Benioff Zone

Late Mesozoic Franciscan rocks of the California Coast Ranges, chaotically deformed and consisting of graywacke, micrograywacke, shale, chert, and mafic pillow lava, are considered to have been

First 40Ar-39Ar Ages from Low-T Mafic Blueschist Blocks in a Franciscan Mélange near San Simeon: Implications for Initiation of Subduction

The Franciscan Complex of California is a type example of an accretionary prism with widespread high-P/T subduction-zone metamorphism. Low-T, fine-grained, lawsonite-bearing mafic blueschists encased

Franciscan geologic history constrained by tectonic/olistostromal high-grade metamafic blocks in the iconic California Mesozoic-Cenozoic accretionary complex

Abstract Subduction generated a NW-trending Andean arc along the Californian margin beginning at ~175 Ma. Coeval high-pressure (HP) transformation of oceanic crust in an east-dipping, subduction zone

Chloritoid‐bearing rocks associated with blueschists and eclogites, northern New Caledonia

Chloritoid-bearing metasedimentary rocks occur in close proximity to blueschists and eclogites in the Tertiary high-pressure metamorphic belt of northern New Caledonia. The typical assemblage of

Detrital zircon U–Pb reconnaissance of the Franciscan subduction complex in northwestern California

In northwestern California, the Franciscan subduction complex has been subdivided into seven major tectonostratigraphic units. We report U-Pb ages of ≈2400 detrital zircon grains from 26 sandstone
