Cerro del Agua scoria cone m. Dos Cerros is a lava shield which covers an area of The Dos Cerros eruption took place close to 14, yr BP as constrained by radiocarbon dating. Rocks teografia these three volcanoes are olivine-hypersthene normative basaltic andesites and andesites with porphyritic, aphanitic, and glomeroporphyritic textures.

Pelagatos rocks also present quartz xenocrysts. Due to their high Cr and Ni contents, and high Mg s, Pelagatos rocks are considered to be derived from primitive magmas, hence the importance of this volcano for understanding petrogenetic processes in this region. Major and trace element abundances and petrography of products from these volcanoes indicate a certain degree of crystal fractionation during ascent to the surface.

However, the magmas that formed the volcanoes evolved independently from each other and are not cogenetically related. Preparqtoria is no clear evidence of important crustal contributions in the compositions of Pelagatos and. The recent activity of NRV, as well as increasing seismic activity at other volcanic centers of the CBCMVC, were preceded by notable changes in various geophysical and geochemical parameters, that suggests renewed magmatic activity is occurring at the volcanic complex.

The onset of this activity started with seismicity located west of the volcanic complex, followed by seismicity at CBV and CMV.

Later instrong seismicity was observed at NRV, with two small eruptions in Local deformation was observed from at NRV, followed by possible regional deformation at various volcanic centers between and NRV shows changes in its activity that may be related to this new magmatic activity.

This suggests that over the coming years, there is a high probability of new unrest or an increase in volcanic activity of other volcanoes of the CBCMVC. This article describes and analyzes a highly significant archaeological context discovered in a late Paracas — BCE sunken patio in the monumental platform mound of Cerro Gentil, located in the Chincha Valley, Peru.

This patio area was used for several centuries for ritual activities, including large-scale feasting and other public gatherings. At one point late in this historical sequence preparatroia deposited a great deal of objects in what is demonstrably a single historical event.

This was quickly followed by a series of minor events stratigraphically immediately above this larger event. This entire ritual process included the consumption of liquids and food, and involved the offering of whole pottery, pottery fragments, botanical remains, bone, lithics, baskets, pyro-engraved gourds, mummies, and other objects.

Such a termination ritual signals parz reorganization in preparatiria regional political structure of Paracas society. Velafrons coahuilensis, a new labeosaurine haddrosaurid Dinosauria: Delgado; Zanno, Lindsay E. Although the holotype specimen is a juvenile individual—as evidenced by its incomplete crest development and relative size compared to other North American lambeosaurines—ontogeny independent autapomor-phies have been identified including quadrate with narrow quadratojugal notch and prepagatoria postorbital with well developed, dorsally positioned squamosal process.

Recycling of water, carbon, and sulfur during subduction of serpentinites: A stable isotope study of Cerro del Almirez, Spain. We use the concentrations and isotope compositions of water, carbon, geografa sulfur in serpentinites and their dehydration products to trace the cycling of volatiles during subduction. Antigorite serpentinites from the Cerro del Almirez complex, Spain, contain wt. The chlorite-harzburgites contain 5.

Dehydration of serpentinite resulted in loss of 5 wt.

Antigorite serpentinites from the Cerro del Almirez complex, Spain, contain 9—12 wt. The chlorite—harzburgites contain 5. Petrological evolution of subducted rodingite from seafloor metamorphism to dehydration of enclosing antigorite-serpentinite Cerro del Almirez massif, southern Spain. Rodingites are common rocks associated with serpentinites in exhumed terrains that experienced subduction and high pressure metamorphism. However, ayolon response of these rocks to devolatilization and redox reactions in subduction settings is not well constrained.

Metarodingites occur as boudin lenses, 1 to 20 m in length and 30 cm to 2 m in thickness. During serpentinization of peridotite host rocks, dolerites and basalts precursor of rodingites underwent intense seafloor metasomatism, causing the parz in Ca and remobilization of Na and K.

Subsequent metamorphism during subduction transformed the original igneous and seafloor metamorphic mineralogy into an assemblage of garnet Ti-rich hydrogrossulardiopside, chlorite, and epidote.

During prograde metamorphism, garnet composition changed towards higher andradite contents. High-pressure transformation of enclosing antigorite-serpentinite to chlorite-harzburgite released fluids which induced breakdown of garnet to epidote in metarodingites. Ti preparatoris by this latter reaction produced abundant titanite. Released fluids also triggered the formation of amphibole by alkalis addition. This garnet has titanite inclusions in the core and rutile inclusions in the rim.

The contact between metarodingites and ultramafic rocks consists of a metasomatic zone blackwall with variable thickness 7 to 40 cm constituted by chlorite, diopside, and titanite. The dynamics of serpentinite dehydration reactions in subduction zones: Dilissen, Nicole; Garrido, Carlos J. Arc volcanism, earthquakes and subduction dynamics are controlled by fluids from downgoing slabs and their effect on the melting prepagatoria rheology of the overlying mantle wedge.

High pressure dehydration of serpentinite in the slab and the subduction channel is considered as one of the main sources of fluids in subduction zones. Even though this metamorphic reaction is essential in subduction activities, the behavior of the fluids, the kinetics and thermodynamics during the breakdown reaction are still poorly understood.

A key to the understanding of the metamorphic conditions prevailing during serpentinite dehydration is to study the two prominent textures -granofels and spinifex-like chlorite harzburgite- occurring in this reaction product. The detailed texture differences in the Chl-harzburgite can provide insights into diverse kinetic and thermodynamic conditions of this dehydration reaction due to variations in effective pressure and drainage conditions.

It has been proposed that difference in overpressure Geografi and deviation from growth equilibrium, i. The magnitude and duration of P’ is highly dependent on dehydration kinetics [Connolly, ]. The fast pressure drop, with spinifex-texture as a product, can be linked to draining events expected after hydrofracturing, which are recorded in grain size reduction zones in this massif.

According to this hypothesis, mapping of textural variation in Chl-harzburgite might be used as a proxy to. Subduction zones are dynamic convergent plate boundaries associated with arc volcanism and earthquakes, which are believed to be controlled by fluids released during devolatilization reactions from the downgoing slab. The high-pressure breakdown of antigorite serpentinite to prograde chlorite-harzburgite is considered to be the most significant source of water in subduction zones.

The Cerro del Almirez ultramafic massif Betic Cordillera, SE Spain is a unique exhumed subduction terrane that preserves this dehydration reaction as a sharp front. Chl-harzburgite in this massif displays two oara textures-granofels and spinifex-like- indicating that antigorite breakdown occurred at different overstepping of the dehydration reaction.

Detailed mapping of textural variations in chl-harzburgite unveils a network of granofels and spinifex-like lenses. These lenses have triaxial ellipsoid shapes with average axial ratios of The growth time and water flux per lens was computed using experimental olivine growth rates for granular and dendritic, spinifex-like olivine. Preliminary results show that formation of spinifex and granofels lenses imply temporal variations of the volumetric water fluxes ranging from 0.

If the time of formation of lenses is inversely proportional to its relative distance to the dehydration front, the 52m thick, chl-harzburgite lens network in Almirez records ca. Our results show that antigorite dehydration in subduction zones occurs in a pra non-steady regime with yearly to decadal geografiq of water fluxes that record variations in the dynamics of slab and fluid.
