Products Projects Offices Who We Are ... Newsletter Porphyry Copper Deposit Life Cycles - A Regional Approach Staff Planned products Project summary: Arizona and adjacent areas of New Mexico and Sonora account for about 10% of world copper production. Within this copper-rich province, issues of urbanization, habitat preservation, and mining are becoming increasingly important. Studies of porphyry copper deposits, their regional geologic and geochemical context, and economic and production history will have a significant positive impact on land-use planning, mineral development, and environmental issues. With a few notable exceptions (e.g. Titley, 2001; Lang and Titley, 1998), past studies of porphyry copper systems in Arizona and adjacent parts of New Mexico and Sonora have focused on individual deposits or districts at map and temporal scales appropriate only to the deposit in question. In this project, we propose to work simultaneously at three principal map scales: province, regions (clusters of mining districts), and deposits, with an emphasis on the provincial and regional scales. Strategy and Approach: The project team will work simultaneously at three scales of investigation: province scale; regional scale (focus starting in the Ray-Globe-Miami-Superior area, but branching out over time to the Sierrita-Tucson Basin and Safford-Morenci areas); and deposit scale (Ray at first and then shifting to Dos Pobres and possibly other deposits). The methodologies are organized into five tasks that cut across the scales of investigation and sites: (1) Mesozoic and Cenozoic crustal framework, (2) regional distribution of chemical elements, (3) characteristics and evolution of hydrothermal systems, (4) dispersion and concentration of materials from porphyry copper and related deposits in the region, and (5) historic lifecycle analysis of porphyry copper exploration and mining.

He later lectured in Rome on the philosophy of Plotinus and was the teacher of the Neoplatonist Iamblichus . He wrote lives of Pythagoras and of Plotinus and edited the Enneads of Plotinus. He wrote extensively against Christianity and on rhetorical and literary themes.

World Tibet Network News Published by the Canada Tibet Committee Friday, December 6, 2002 5. Bay Resources Ltd Announces Major Porphyry Copper-Gold Exploration Deal in Tibet MELBOURNE, Australia(BUSINESS WIRE)Dec. 4, 2002Bay Resources Ltd (a Delaware Corporation listed on the over the counter market OTC:BYRE) announces that it has now signed the contract for a co-operative joint venture with the Tibet Bureau of Geology and Minerals Exploration and Development ("Tibet BGMR"), China, previously announced on October 31, 2002. Bay Resources can earn a minimum 51% interest, with the right to earn up to 70% interest by a further capital investment, in two drill tested porphyry copper-gold deposits (Chong Jiang and Qu Long). Bay Resources can earn a 70% interest in the surrounding exploration area of approximately 15,000 square kilometres, where previous exploration by the Tibet BGMR has defined a further six porphyry targets, which have not yet been drill tested. These additional six porphyry targets were defined by regional geochemical surveys, with anomalous areas being further refined with ground geophysics

Porphyry Laura Fiora Department of Mineralogical Sciences and Petrology, University of Torino (Italy) The scientific name Porphyry, in the modern scientific classification of rocks, it is used only as a commercial term to indicate a volcanic rock with peculiar characteristics and susceptible to particular uses. The classic porphyry and trentine is the volcanic rock coming from the Italian region of Trentino- Alto Adige. This stone has always had a great symbolic value, apart from aesthetic: the emperors, personifying divinity, lived surrounded by porphyry, they were born in rooms cladded with porphyry and many Roman emperors were even buried in sarcophagus made of porphyry. Another famous porphyry of ancient times is the Green Porphyry, found in Greece, in the province of Laconia, close to the city of Sparta; it was also called Serpentine Porphyry. This porphyry is easily recognisable by the presence of crystals of light green feldspar in an olive green matrix. In more recent times the more famous porphyry is from Trentino, a volcanic rock which is extracted in the region Trentino- Alto Adige (Italy), characterised macroscopically by felsic phenocrystals immersed in a mass of red colour or pinkish grey. In the region of the meridian Dolomites, around 260 million years ago, there were important flow of lava (Brondi et al.1974) which formed volcanic rock on becoming solid, the steady characteristic of which is the presence of diverse fracture systems developed during the cooling of the lava and / or during the formation of the Alpine orogenic belt that conditions the natural splitting of porphyry in slabs (fig.1).
