The United States has a rich history of mining including uranium (U)-mining, coal mining, and other metal mining. Cardiovascular diseases (CVD) are largely understudied in miners and recent literature suggests that when compared to non-U miners, U-miners are more likely to report CVD. However, the molecular basis for this phenomenon is currently unknown. In this pilot study, a New Mexico (NM)-based occupational cohort of current and former miners (n = 44) were recruited via a mobile screening clinic for miners. Serum- and endothelial-based endpoints were used to assess circulating inflammatory potential relevant to CVD. Non-U miners reported significantly fewer pack years of smoking than U-miners. Circulating biomarkers of interest revealed that U-miners had significantly greater serum amyloid A (SAA), soluble intercellular adhesion molecule 1 (ICAM-1, ng/mL), soluble vascular cell adhesion molecule 1 (VCAM-1, ng/mL), and VCAM-1 mRNA expression, as determined by the serum cumulative inflammatory potential (SCIP) assay, an endothelial-based assay. Even after adjusting for various covariates, including age, multivariable analysis determined that U-miners had significantly upregulated VCAM-1 mRNA. In conclusion, VCAM-1 may be an important biomarker and possible contributor of CVD in U-miners. Further research to explore this mechanism may be warranted.

The Iberian Peninsula is one the most mineralized parts of Europe, with a long history of metal mining from prehistoric and Roman to modern times. The earliest evidence for copper metallurgy dates to the fifth millennium BC; however, distinctive Chalcolithic metalworking traditions did not emerge in most regions until 3000 BC onwards. There are widespread occurrences of copper mineralization in Spain and Portugal, including many areas with deposits of lead, tin, silver, and gold. Copper deposits occur in the Galician and Cantabrian mountain ranges of northern Spain, extending east to the Pyrenees. They are also numerous in central Spain, in the provinces of Madrid, Avila, Salamanca, and Segovia in the Central Range, and also in the Toledo and Betic mountains of Cordoba. Farther south, there are major copper deposits in the so-called Pyrite Belt, extending from Seville to Huelva into southern Portugal, and also in the Penibetic range from Cartagena to Malaga crossing the sierras of Almeria (Rovira 2002: fig. 3c; see Delibes de Castro and Montero Ruiz 1999 for regional surveys of copper deposits and indications of early mining; also Gómez Ramos 1999; Hunt Ortiz 2003). The widespread availability of ore deposits was a significant factor in the establishment of copper metallurgy in Iberia. How early is contentious, as is the means by which the new technology first developed in different parts of the peninsula. The older explanation of metal-seeking colonists from the east Mediterranean introducing this technology to southern Spain was replaced in the 1960s by a model that emphasized autonomous development (Renfrew 1967, 1973; Montero Ruiz 1994). This was based on the apparent antiquity of copper mining and metallurgy in Iberia and the distinctive technological processes that developed there relative to other parts of Europe. The earliest indication of copper metallurgy in Iberia may come from the settlement of Cerro Virtud in Almeria, south-west Spain. A single sherd from a metallurgical crucible used to reduce oxidized copper ore was discovered in a layer dated to the early fifth millennium BC (Montero Ruiz and Ruíz Taboada 1996; Ruíz Taboada and Montero Ruiz 1999).

The history of exploration of the Ilímaussaq alkaline intrusion is briefly reviewed. Geological and mineralogical investigations were first carried out by K.L. Giesecke in 1806. Later K.J.V. Steenstrup, N.V. Ussing, C.E. Wegmann and a number of others have undertaken studies in and around the intrusion. The intrusion is mainly composed of peralkaline (agpaitic) nepheline syenites and is rich in rare elements and rare minerals. A number of minerals were first discovered in this intrusion, viz. ænigmatite, arfvedsonite, britholite, chalcothallite, epistolite, eudialyte, igdloite (= lueshite), ilimaussite, naujakasite, polylithionite, rinkite, schizolite, sodalite, sorensenite, steenstrupine, tugtupite and ussingite. Renewed geological and mineralogical activity has taken place in Ilímaussaq during the last few years in connection with an examination of the economic geology of the area. A series of publications is in preparation. It was therefore considered to be of some value to present an account of the work until now and to prepare a list of the minerals so far identified and of the papers dealing with the intrusion. The bibliography, together with that prepared by Bøggild (1953), contains the titles of all the papers on the mineralogy, geochemistry and geology of the intrusion known to the writer.

Abstract The porphyry deposit name has a long and fascinating etymological history of over 3,000 years. “Porphyry” is derived from the ancient Greek word porphyra (πoρϕύρα), or purple. It was originally applied to a rare purple dye, Tyrian purple, extracted by the Phoenicians from murex shells. It was later applied to a prized purple porphyritic rock, Imperial Porphyry or Porfido rosso attico, quarried by the Romans from Mons Porphyrites in the Eastern Red Sea hills of Egypt from the first to fifth centuries A.D., and used as a monumental stone in Imperial Rome and Byzantium (Istanbul). The name evolved in the field of igneous petrology to include all rocks with a porphyritic texture, regardless of their color. Mining of the first porphyry copper deposits, which were originally called disseminated or low-grade copper deposits, started in 1905. As a result of the close spatial and genetic relationship to porphyry stocks, they became known as porphyry copper deposits. The term was first used by W. H. Emmons in his 1918 textbook The Principles of Economic Geology, but it was originally used more as an engineering and economic description, as in Parsons’ 1933 book The Porphyry Coppers. It was slow to catch on in the geological literature. It was first used in the title of a paper in Economic Geology in 1947 but did not gain widespread use until the 1970s, following the publication of seminal papers on porphyry models and genesis by Lowell and Guilbert (1970) and Sillitoe (1972, 1973).

Chemical Conditions

The history of Atlantic salmon (Salmo salar) runs of the Northwest Miramichi from 1950 to 1973 is reviewed. Decreases in these runs are related to degrading of ecological conditions in the river's rearing reaches as a result of adverse chemical conditions attributable to recent developments in forest management and to base metal mining. Diversion of indigenous adult stocks into other streams of the system as a result of pollution of the home stream by mining, pulpmill, and other human activities is examined and evaluated. Increase of commercial catches as a result of pollution-caused delay in the estuary of migrating adults is analyzed. Grave depletion of stocks as a result of the combined effects of these factors plus distant-water fishing is identified, as is incipient recovery of stocks when home-water commercial fishing was eliminated and pollution abatement measures were introduced to the river. A suppressing effect of heavy angling pressure on stock abundance when stocks are low is noted.
