Cheap Web Site Hosting PORPHYRY COPPER DEPOSITS Mineral Deposits... Earth Science Australia... Based on Notes From The Prospecting School on the Web Introduction Distribution and age Classification What to look for in the field ... Conclusion INTRODUCTION The major products from porphyry copper deposits are copper and molybdenum or copper and gold. The term porphyry copper now includes engineering as well as geological considerations; It refers to large, relatively low grade, epigenetic, intrusion-related deposits that can be mined using mass mining techniques. Geologically, the deposits occur close to or in granitic intrusive rocks that are porphyritic in texture. There are usually several episodes of intrusive activity, so expect swarms of dykes and intrusive breccias. The country rocks can be any kind of rock, and often there are wide zones of closely fractured and altered rock surrounding the intrusions. As is described following, this country rock alteration is distinctive and changes as you approach mineralization. Where sulphide mineralization occurs, surface weathering often produces rusty-stained bleached zones from which the metals have been leached; if conditions are right, these may redeposit near the water table to form an enriched zone of secondary mineralization. top of page..

PORHYRY (233-304 A.D.) P orphyry , the head of the Syrian school, was the most important among the disciples of Plotinus . Porphyry was born at Batanea , Syria in A.D., and he died in Rome in A.D.. He wrote lives of Plotinus and Pythagoras , treatises De abstinentia and De antro nymphartim , a letter to Marcella , another De diis doemonibus ad Anebonem , a brief compendium of the doctrines of Plotinus entitled Aphormai pros ta noeta . he also authored an introduction to the " Categories " of Aristotle , besides a number of other works no longer in existence. The work last named, Aphormai pros ta noeta, is of considerable importance in the history of philosophy, as it contains the germ of the whole controversy between realism and nominalism . The religious character of Porphyry's philosophy is shown by his placing its aim in the " saving of the soul ." He mentions four kinds of virtues: the political , which make an ordinary good man; the purifying , which make him a "daemonic" man; those which look up to the nous, their cause, constituting the rational activity of the soul ; and the virtue of the nous itself, the

Porphyry Copper Deposits of the World: Database, Maps, and Preliminary Analysis By Donald A. Singer, Vladimir I. Berger, and Barry C. Moring INTRODUCTION This publication contains a computer file of information on porphyry copper deposits around the world. It also presents new grade and tonnage models for three subtypes of porphyry copper deposits, maps showing locations and general ages of these deposits, and a preliminary analysis with a number of figures summarizing many of the properties of these porphyry-style deposits. These summaries can be considered a new, quantified, form of most parts of descriptive models such as those in Cox and Singer (1986). The value of this information and analyses depends critically on the consistent manner of data gathering. For this reason, we first discuss the rules used in this compilation. Next the fields of the data file are considered. Finally, we discuss some of the things that can be done with the data.

U.S. Geological Survey Open-File Report 99-556, Online Version 1.0 Giant Porphyry-Related Metal Camps of the By Felix E. Mutschler , Steve Ludington , and Arthur A. Bookstrom INTRODUCTION Porphyry-related metal deposits are large-tonnage, generally low-grade, hydrothermal deposits related to igneous intrusions emplaced at high crustal levels. Mineralization may be confined to pluton-hosted disseminations, stockworks, vein sets, and breccias and (or) occur in skarns, replacements, veins, and disseminated deposits peripheral to the inferred source pluton. Coeval epithermal precious metal-dominated deposits may occur above, or be telescoped onto, porphyry systems. This spectrum of deposit types includes many of the world's largest accumulations of Cu, Mo, Au, Ag, Sn, and W. As such the deposits represent critical economic resources and important exploration targets (Gilmour et al., 1995; Kirkham and Sinclair, 1996; Singer, 1995). To prospect efficiently for undiscovered mineral deposits, or to speculate about future metal supply, it is useful to define the size, distribution, and geologic characteristics of known deposits. It is to that end that we have compiled this database, the release of which is part of a larger effort to characterize the world's largest and most important porphyry-related deposits. We hope that this compilation can be of aid to researchers, explorationists, and students alike. We also recognize that any compilation effort is, by its very nature, incomplete, as well as out-of-date as soon as it is released. Thus, we welcome any corrections or updates to the data presented here and request that you direct any communications to Felix Mutschler at 509-359-2854 or Steve Ludington at 650-329-5371.

Porphyry, Macarius Magnes, and Hoffmann A Review of R.Joseph Hoffmann, Porphyry's Against the Christians The literary remains , Prometheus Books (1994) The 16-book work by the Neoplatonist Porphyry Against the Christians is lost. Constantine ordered that all copies should be destroyed ; a century later Theodosius tacitly acknowledged that this had not occurred by issuing a similar edict in 448 . Although Christians were generally interested in Neoplatonism, and many of Porphyry's major philosophical works still survive , it is hard to see who would have copied a work calculated to offend everyone reading or writing books between 550 and 1450, even without such a edict. Books that insult their readers and copyists have few chances of survival. In 1867, a 15th century manuscript containing an unknown work with the title the Apocriticus of Macarius Magnes was discovered in Epirus and taken to Athens by C. Blondel. The work had been written in 5 books; the Athens MS contained only the portion from the middle of book 2 to the middle of book 4. Blondel made an edition of the text from the MS, which was very corrupt, but died before he was able to publish. The book was published by his friend Foucart in 1876, but without an introduction, and this edition is itself now very rare . This remains the only edition of this work. In 1877 Duchesne examined the manuscript again, and provided a description

PORPHYRY ON CHRISTIANITY (270CE) Porphyry of Tyre (232-305CE) Was one of the more prominent pagan intellectuals to question the claims of the early Christian church. He had been a student of a school run by Plotinus in Rome. After Plotinus' death, Porphyry developed a distaste for what he thought of as the superstitions of the empire. He wrote a book discussing the defects of the cults called Pro Anebo. Porphyry was said to have heard Origin's preaching in his youth, and to have found him lacking in philosophical consistency. He is also known to have studied the Hebrew scriptures, especially the prophets. His book, Against the Christians, (Kata Christian), was written some time after 270CE and remained popular until 448, when his fifteen-book Kata, along with various books from other authors, were sentenced to be burned. What very little we know of his work come to us preserved in the writings of Eusebius, Apollinarius, and, primarily, the Apocritus of Macarius Magnes. The following excerpts are taken from Porphyry's Against the Christians: The Literary Remains , translated by R. Joseph Hoffman, Prometheus Books, 1994.

Both Porphyry's parents were Phoenician and he would only get the nickname Porphyry later in his life as we shall explain below. Porphyry was named after his father so for many years he was known as Malchus. As a young man Porphyry tried to gain as broad a knowledge as he possibly could by studying many languages and religions. At that time Athens was the main centre for learning, so it was natural that someone with a thirst for knowledge as Porphyry had should travel there to continue his studies. In Athens Porphyry became a student of Longinus who [8]:- ... was a 'living library and walking museum' and the academic's critical attention to detail, clarity of style and erudition left their permanent mark on the keen student.

In this patch Triassic (Ladinian, according to ) effusiva occur that are so amorphous they can be used as a raw material for knapped lithics. Material and colour: There is hardly any other lithic that is know by as many names as this stuff. As the material was recognized as something typical, which was at the end of the 19th century, it was misidentified as "grey chalcedony" and its origin given as the Avas Hill near Miskolc. This was only to be the start of a long history of local names which include "Szeletian quartz porphyry", "glassy quartzporphyry", "felsitic quartzporphyry", "striped felsitic rhyolite tuff" and "ash-grey porphyry".

SOME PORPHYRY HISTORY 2 000 B.C. The Pharaohs worked porphyry. 300 B.C To the Ptolemies in Egypt and the Greeks purple was the royal colour, and therefor porphyry (from Greek porfyreos, purple) suited them best of all minerals. Production of porphyry objects increased. 200 B.C Cleopatra made red the royal colour instead of blue. The emperors alone were privileged to use the purple colour. Of red porphyry from the Red Sea area lots of porphyry objects such as wainscoting, flooring, sarcophagi, baths etc. were manufactured. Once again the difficulty working the hard porphyry was overcome. E.g. porphyry was used by Louis XIV in Versailles and by the cardinals Richelieu and Mazarin as a symbol of power. Porphyry for the first time was mentioned in writing in Swedish. Experiments polishing porphyry were carried out. Councillor Nils Adam Bielke showed samples of porphyry to Gustaf III. The king was interested and wanted to decorate the Haga Palace with porphyry. Karl XIV Johan bought the works in the name of his son Oscar (Oscar I). The sarcophagus was ready to be delivered but had to wait for suitable surface for sledging for four years.
