The aim of ARTCADHi, the transdisciplinary research network which designed Porphyry and Steatite software, is to experiment the feasibility of a digital hermeneutics. The main idea is to offer a digital place where scholars could build their interpretation about document corpora and confront it with the viewpoints of other scholars. In order to be easily confronted the viewpoints are modeled th...

Porphyry is a stone material, volcanic in origin, characterised by its development along parallel planes (photo n. ). This characteristic allows for it to be used as a semi-finished product (untreated photo n. ) as well as after “splitting”. Porphyry’s considerable resistance to wear and tear, due to atmospheric agents, is the feature that has consented to its diffusion in street furniture but ...

a high percentage of world copper production is obtained from porphyry copper reserves, these reserves are characterized by: very high tonnage, greater horizontal dimensions than vertical, association with stock like intrusion masses, dispersed minerals in the porphyry mass and in its neighbor rocks, intense sericitization and inplace silicification. the porphyry coppers are concentrated by flo...

Nos travaux s’insèrent dans un projet du réseau ARTCADHi visant à offrir aux chercheurs en Sciences Humaines des assistants à la construction du sens dans des bibliothèques numériques spécialisées. Dans ce cadre, limiter la description des documents à une indexation unique, fixe et effectuée par un tiers, revient à nier leur expertise. Porphyry propose l’instrumentation du travail des chercheur...

To reconstruct the magmatic–hydrothermal processes leading to porphyry Mo ore formation at the Climax Mo mine, Colorado, four magma units that were emplaced before, during and shortly after the mineralization events were investigated: (1) a pre-mineralization white dike of the Alma district; (2) the syn-mineralization Chalk Mountain Rhyolite; (3) a lateto post-mineralization rhyolite porphyry d...

The Baghuo gold mine (Kuhzar) is located about 100 km S-SE of Damghan. The area is part of Torud- Chahshirin volcano- plutonic belt. The hosts of quartz – tourmaline veins are mainly granite, granodiorite and volcanic rocks such as andesite and dacite.  Mineralization occurs as a copper- gold bearing silica vein. Quartz, pyrite, chalcopyrite, gold, hematite, malachite, azurite, covellite and Fe...

Geochemical signatures throughout the layered Earth require significant mass transfer through the lower crust, yet geological pathways are under-recognized. Elongate bodies of basic to ultrabasic rocks are ubiquitous in exposures of the lower crust. Ultrabasic hornblendite bodies hosted within granulite facies gabbroic gneiss of the Pembroke Valley, Fiordland, New Zealand, are typical occurrenc...

Eoarchean [3.6 to 4.0 billion years ago (Ga)] tonalite-trondhjemite-granodiorite (TTG) is the major component of Earth's oldest remnant continental crust, thereby holding the key to understanding how continental crust originated and when plate tectonics started in the early Earth. TTGs are mostly generated by partial melting of hydrated mafic rocks at different depths, but whether this requires...

Jiama is a super-large porphyry copper–polymetallic deposit located in the Gangdese metallogenic belt of southern Tibet. The consists combination polymetallic skarn, Cu–Mo mineralization at contact between Porphyry and hornfels, distal Au fault. current metal reserves are 7.4 Mt Cu, 0.6 Mo, 1.8 Pb–Zn, 6.65 Moz Au, 360.32 Ag, with skarn to porphyry–hornfels host-rock ratio ~3:1. Based on detaile...
