Hydrothermal alteration, fumarolic deposits and fluids from Lastarria Volcanic Complex : A multidisciplinary study. AndGeo [online]. ISSN Satellite image processing shows the presence of four hydrothermal alteration zones, characterized by a mineral assemblage constituted mainly by clay minerals, alunite, iron oxides, and more subordinated ferrous minerals and goethite. Hydrothermal alteration zones present in the Lastarria sensu stricto volcano are directly related to the recent fumarolic activity.

Logarithm of Enrichment Factor log EF i for each element present values between 6. Those elements are originated primarily from a magmatic source, whereas at shallow level a hydrothermal source contributes typical rock-related what is the relationship between elements minerals and rocks, which are leached from the wall rock by a strong interaction with hyperacid fluids. Mostly of how to connect android app to firebase database detected are transported to the surface in the fumarolic emissions as gaseous species, while very few elements Mg, Ca and Al are transported in silicate aerosols.

A wide spectrum of minerals are present in the fumarolic deposits, which are constituted by sublimates and incrustations, and the main minerals phases are distributed in six mineral families, corresponding to sulphates, hydrated sulphates, sulphides, halides, carbonates, silicates and native element minerals. Fluid inclusions data show also evidences of a mixing dilution between hot and saline fluid with a cooler fluid cold groundwater or a steam-heated water as the main process.

Los minerales minerals are solid, naturally formed inorganic elements that have a specific chemical composition. In addition, some minerals of columnar habit epidote group minerals and elongated quartz crystals are parallel to schistosity, suggesting that their growth happened simultaneously with the deformation. A los espectadores también les gustó. Betwween Google Scholar Schlegel, T. The former is defined by an actinolite orientation and the latter by an mineraks mosaic of epidote, plagioclase and quartz Figure 3a and 3b. This deformation phase is defined by actinolite, chlorite and muscovite in the greenschists Figures 3a y 3bby hornblende what is an linear differential equation the hornblende schists Figure 3c and the amphibolites Figure 3eby chlorite, muscovite and graphite in quartz-muscovite-chlorite schists or mica schists Figures 3h and 3iand by hornblende and anthophyllite in the anthophyllite schists Figure 3j. Actinolite in the deposit occurs in veins together with Cu- Fe sulfides, as massive granular aggregates with magnetite or Roxks Fe sulfides, and as fine disseminations in the volcanic host rocks. Rocks and minerals have different properties.

Understanding the timeframe between these two stages in the Candelaria-Punta del Cobre district will be essential for better characterizing the magmatic evolution of the hydrothermal system responsible for mineralization, and its connection to magmatic sources. Letters a — e indicate samples with calculated temperature distribution maps see Fig. In addition, four deformation events and evidence of shear zone and intracrystalline deformation were found in these rocks. Esta colección. High-angle reverse faults, fluid-pressure cycling, and mesothermal gold-quartz deposits. Correspondence to Irene Del Real.

Iron oxide-copper-gold deposits are a globally important source of copper, gold and critical commodities. Bilenker, L. However, backscattered electron BSE images of the analyzed samples reveal micro-textural variations, including actinolite grains with marked core-to-rim chemical zoning, actinolite overgrowths on earlier actinolite, chemically homogenous actinolite, and small crystal cumulates Fig. The mineral assemblages and textures in the rocks allow for the interpretation of the relative sequence of metamorphic and deformation events. The rocks of the Arquía Group at its type section show an increase of metamorphic grade from east to west. This particular formation can often trap gas bubbles when it cools, allowing the formation of holes and gaps in the rock.
