Tectonic controls and fluid evolution of auriferous quartz veins in the La Codosera area, SW Spain
No full textDuring the Hercynian orogeny in SW Spain, at the Southern Margin of the Central Iberian Zone, veins were formed during three different stages of the local transpressive deformation sequence: during early ductile deformation; through granite intrusion; to late brittle faulting. Fluid inclusions in seven vein types have been investigated and show a change in composition over time. Peak metamorphism coincided with early ductile folding and associated thrusting which formed the Central and Southern Ridges. Fluid inclusion data, combined with mineralogical constraints and vitrenite reflectance geothermometry, constrain this metamorphism to 410-425oC and 3.1-3.4 kbar. A low salinity aqueous fluid (c.6.4wt% equiv NaCl) of high density was in equilibrium with the peak metamorphic assemblage of quartz-albite-muscovite-chlorite. After emplacement of the Tres Arroyos Li Pegmatite, in the roof zone of the Alburquerque Granite, a high temperature (> 400oC) magmatic fluid of low salinity (c.6.6 wt% equiv NaCl) mixed with a lower temperature fluid derived from the contact metamorphic aureole at pressures in excess of 1.5 kbar. At an early stage the fluid unmixed into an aqueous phase and a carbonic phase with significant quantities of N2 + CH4, generated by fluid interaction with pelites. The fluid was locally buffered by a quartz-muscovite-albite assemblage within the pegmatites. Late kinematic pyrite-arsenopyrite-gold bearing quartz veins within the Central Ridge and Los Algarbes areas were formed on obliquely reactivated thrust faults and as structures related to high-angle right-lateral faults. This late right-lateral antithetic bookshelf faulting occurred along a releasing bend in the Badjoz-Cordoba shear zone. These structures provided favourable sites for fluid infiltration. Gold occurs within pyrites and arsenopyrites either as a lattice component or as finely disseminated particles. During the late brittle faulting, relatively reduced carbonic fluids (H2O-CO2-N2-CH4 with H2S as the dominant dissolved sulphur species) unmixed at c310o and 1.5 kbar and CO2-N2-CH4 were partitioned into the vapour phase. A late retrograde boiling event occurred at 250oC and > 750 bars after gold mineralisation. High contents of N2 (up to 8.7 mole%) are associated with the mineralised veins produced by fluid-rock interaction either locally or at the fluid source. The lack of extensive wallrock alteration and thermodynamic calculations suggest that the fluids were partially buffered by a quartz-muscovite-albite±k-feldspar assemblage in the wallrocks. Stable isotope data (δ18O, δD & δ^34S) are most consistent with a metamorphic source for the mineralising fluids deeper in the crust. Unmixing oxidised the fluid and preferentially partitioning H_2S into the vapour phase promoting the deposition of gold, by destabilisation of the reduced sulphur complexes.</p
AC-6-U.S. Naval Planes Flying in Formation, Langley Field, VA/Thank-You Card from Stephen Tury to the Hungarian Defense Council.
No full textThis postcard, which depicts U.S. Naval planes flying in formation, was sent to the Hungarian Defense Council by Private Stephen Tury. The Council was organized in New Brunswick by leaders of local Hungarian churches and societies. During the Second World War it sent supplies, such as the carton of cigarettes Tury is thanking it for, to members of the military of Hungarian descent from the New Brunswick area
John Dee and the Seven in Lancashire: Possession, Exorcism, and Apocalyse in Elizabethan Engand
No full textSTEPHEN BOWD, 'John Dee and the Seven in Lancashire: Possession, Exorcism, and Apocalypse in Elizabethan England'. In 1596 John Dee, warden of Christ's College of Manchester, was approached by Nicholas Starkey of Cleworth Hall for advice about some members of his household who had been possessed by the devil for almost two years. Dee's involvement with the exorcism of the 'Seven of Lancashire', as they were known, was closer than has been previously thought and it is reconstructed in this article on the basis of published and manuscript sources. Dee's longstanding interest in possession and exorcism is also described here and placed in the context of religious tensions in England, particularly in the north, at the end of the sixteenth century. <br/

Conversing with Angels: John Dee and His Quest for Divine Knowledge
No full textabstract: My honors thesis, entitled “Conversing with Angels: John Dee and His Quest for Divine Knowledge”, was a study of the Elizabethan scholar John Dee and the angelic conversations he is most known for. I decided to focus my work on the nature of the conversations, as well as looking for an answer to the question of why Dee spent years of his life figuring out how to contact, invoke, and converse with God’s divine beings. After extensive research I found five scholars whose works held six different arguments as to Dee’s motivations for the conversations.
I began my thesis discussing the conversations themselves, starting with Dee’s scryer, Edward Kelly, and the ways in which he was able to contact the angels. I also went into detail about the prayers and psalms Dee used to invoke the angels, as well as the multiple topics discussed throughout the conversations. I found that Dee’s transcriptions of the conversations were written in a form of short hand, and often included his own commentary to go along with what the angels told him. After the general overview of the process that let to the conversations, as well as the conversations themselves, I moved on to discussing the six different arguments from the five scholars: Deborah Harkness, Nicholas Cluelee, Stephen Clucas, György Szönyi, and Stuart Clark.
A quick rundown of each argument is as follows. Deborah Harkness argued that Dee’s conversations found their root in apocalyptic concerns, while Harkness and György Szönyi believed he was trying to bring religious reformation to the world. Stephen Clucas felt Dee was doing everything to bring glory to God, and Nicholas Cluelee claimed Dee was conversing with angels for a purely scholarly reason. Finally, Stuart Clark played devils advocate and argued that Dee was not actually talking to angels, but rather to demons.
After much consideration, taking each of the six interpretations into account, I concluded my thesis by arguing in agreement with György Szönyi and Nicholas Cluelee. I believed, like Szönyi, that Dee was doing all of this work to bring glory to God. But that was most likely only to a lesser extent, for when it comes to Dee’s main reasoning behind the conversations, I argued, like Cluelee, that Dee was a scholar through and through. He had spent his whole life chasing after the idea of omniscience, finally looking to the heavens in hopes that God would share his divine knowledge. Therefore, while Dee might have been conversing with angels for many different reasons, I believe that the main reason was somewhat selfish. He was a scholar with the chance to learn the secrets and knowledge of the divine, there was no other motivation needed

‘This paradoxall Restitution Iudaicall’: the apocalyptic correspondence of John Dee and Roger Edwardes
No full textDespite the later prominence of apocalypticism in John Dee’s ‘angelic conversations’ in the years 1583–85, his correspondence with Roger Edwardes in 1580 about the correct interpretation of eschatological passages in the bible has received surprisingly little attention in Dee scholarship. In this article I give an account of Edwardes’s ill-fated political career (as the author of manuscripts which he circulated in 1568 and 1579 relating to the Elizabethan Succession issue, for which he was imprisoned), and the apocalyptical writings (concerning the restitution of the Jews) which he sent to divines in England and Germany for validation. These apocalyptical reflections, which Dee called ‘the boke of Domes Day’, were the subject of the Dee–Edwardes correspondence. Whereas the divines with whom he corresponded were largely lukewarm, Edwardes found a sympathetic reader in Dee. I conclude by considering the significance of the Dee–Edwardes correspondence for Dee’s increasingly apocalyptical outlook, which began in 1564 with prophecies concerning the Habsburg dynasty in his Monashieroglyphica, and reached a fever pitch in the 1580s when he began working with the ‘skryer’ Edward Kelley. The careers of Dee and Edwardes have in common a belief in inspired exegesis and prophetic singularity, and I show that one can detect traces of Edwardes’s concern for the redemption of the Jewish people in Dee’s angelic writings
