In Ecuador and Colombia there is a belt of crystalline rocks of the Jurassic age, in which discoveries of copper porphyry-type mineral deposits have been made during the last decades. The reason for carrying out the present study is in the northern part of the Putumayo department, a prospective area for the discovery of porphyry-type mineral deposits of Cu-Mo, like Mocoa. For the identification of geochemical anomalies from the regional exploration stage, geostatistical modeling is used through the conditioned turning bands simulation tool, using data from 443 fine current active sediment samples, taken in basins within the study area draining mainly Jurassic age rocks. The automatic cartography of turning bands carried out for each of the elements under study identified four anomalies of regional importance, corresponding to geochemical signatures in the identification of copper porphyry systems on the surface.

Since the middle of the 20th century, the evidence of porphyritic Cu-Mo mineralization occurrence has been known in the Sierra Maestra (Cuba). Despite large outcrops have been described, as well as the presence of an intense hydrothermal alteration and the mineralization of veins with associated precious metals, these manifestations have not been fully evaluated due to their low Cu content. In order to clarify the characteristics of this kind of mineralization and evaluating its perspectives, the available information in geological reports was reviewed and systematized, and geochemical and geophysical criteria were applied. As a result, were characterized and delimited six new areas with perspectives to develop prospecting work for porphyritic copper and two previously reported were incorporated. [ABSTRACT FROM AUTHOR]

Section 32 of Iamblichus' De anima begins with the analysis of three possible explanations about the way the soul enters the body. The first two are anonymous while the third one is attributed by the philosopher of Chalcis to Plotinus's followers. The theme is announced in the previous section (31) where from the beginning a reference to "Hippocrates, the Asclepiade" can be read connected to a previous lost sentence which would mark the argument's outset. As a possible source for Iamblichus, Porphyry is often cited. Porphyry includes views from Hippocrates, from an anonymous philosopher, and from Numenius of Apamea about the moment when life begins and the soul naturally becomes associated with the body. In the development of the aforementioned sections 31 and 32, an implicit knowledge of the embryological hypotheses of the time is appraised. [ABSTRACT FROM AUTHOR]

Plotinus’ last words uttered to his physician and disciple Eustochius (V.P. 2.25-27) are an exhortation to philosophy, expressed as a last piece of advice, which connects with the Platonic theme of the ascent and return of the soul. It is necessary to flee from the world here to the world over there, to return, like Odysseus, to the true homeland. In the Plotinian architecture, the three divine hypostases as well as constituting the structure of the transcendent reality are also latently present in man. How to explain in words that effort to elevate what is divine in us to what is divine in the universe? Beyond Eustochius, the only immediate recipient, this exhortation-recommendation extends to all humanity. [ABSTRACT FROM AUTHOR]

From the texts of authors of Classical Antiquity (De abstinentia by Porphyry and De re coquinaria attributed to Apicius, among others), this paper analyzes the notion of pure food and their implication in the diet and over it. First, it studies the concept of diet, as a part of the therapeutic, that is, one of the medical instruments to restore health. For ancient Greeks and Romans, in addition to healthy eating, rest and exercise, the diet includes baths and purges; both elements are related to the idea of purity. Secondly, this paper shows the Latin terms that are used to describe pure food, crudus, recens, viridis and purus, specifically in the cases of olive oil and honey, which are considered the pure foods most characteristics. To conclude, pure food requires neither cooking nor preservation for consumption, and also can be consumed without mixing or adding any element to the product itself. In consequence, the notion of purity is associated not only with a dietetic domain, but this notion also reaches ethical and metaphoric dimensions. [ABSTRACT FROM AUTHOR]

The Sentences of Porphyry, that are a compendium of the Plotinus Enneads, include a review of the locus vexatus of the third century Platonism, which has its origin in the interpretation of a controversial passage of Timaeus, 39e. We will review the historical causes of Porphyry, under Longinus influence, and the controversy with Amelius and Plotinus on his arrival in Rome. His subsequent "retraction" takes him to accept that Intellect is identified with the multiplicity of intellections that intelligizes. Intellect is an intelligent subject and, at the same time, an intelligized object, that is, itself exerts on its own intellectual activity. Our analysis will seek to bring together texts of the Sentences, particularly from the 43, with excerpts from Plotinus treaties. [ABSTRACT FROM AUTHOR]

The La Caridad mine is located in Sonora and it is the largest mine in Mexico. This is a porphyry type ore deposit dated at 54 Ma. Beautiful green centimetric size crystals of vivianite (Fe3(PO4)2·8H2O) have been discovered at Mercator coordinates 638232 N and 3354816 E, and between benches 1305 and 1410. The identification was confirmed using X ray diffraction and fluorescence. The mineral is in the core of the orebody, in the potassic hydrothermal alteration zone, but in the transition from the supergene enrichment to the primary sulfide zone. The origin of the vivianite is probably meteoric, during supergene enrichment. The La Caridad mine is the second locality in Mexico where the presence of vivianite has been reported.
