Much of Europe, from Northern Scandinavia and Iceland to the Southern Iberian Peninsula, has been covered by valley glaciers and extensive ice sheets during long periods of the Pleistocene. Consequently, in both highlands and wide areas of the lowlands (particularly in Sweden, Finland, Northern Russia, and Central Europe) deposits of glacial origin (frontal moraines, different types of tills, lateral moraines, drumlins, and eskers) and other deposits indirectly related to glaciers (fluvioglacial terraces, lacustrine deposits, kames, and outwash plains) can frequently be found.

Mining and metals continue to be among the best performing global equity sectors, but conflicting issues – from “pricing bubbles”, “imminent recessions”, “demand destruction” to “resource scarcity”- are confusing investors. Nevertheless, the importance of mining to the world has become very apparent in recent years, as commodity and equity prices have exceeded most expectations. Therefore, investments in commodities become more attractive as a long-term investment as they are a safe haven in times of economic crisis and provide a protection against currency devaluation. Thus, it is useful to know how to value metals and mining companies <...>
A variety of techniques have been used in attempts to date the mineralization in Carlin-type deposits in the Great Basin, with highly variable results. These techniques and results are reviewed in this paper, along with presentation of two new dates, for the Rodeo deposit on the Carlin trend and for the Barneys Canyon deposit in Utah. Complete resetting of sericite by hydrothermal fluids of the temperature and duration of hydrother-mal activity that form Carlin-type deposits is considered highly unlikely. Therefore, dates from sericite are generally of questionable value unless that sericite can be shown to have formed during the same hydrothermal event during which Au was deposited. For the deposits that have been investigated to date, sericite dates rarely, if ever, record the age of Au mineralization. However, sericite ages do appear to record pre-Au events in some districts. Such events may have contributed to ground preparation and, to a much lesser extent, to the tenor of the ore. Fission-track and U/Th-He techniques provide important age constraints on mineralization in some districts but also suffer from a less than clear association with Au. Rb-Sr dating of galkhaite, an Hg sulfosalt, provides the only direct age of mineralization, but galkhaite has been recognized in only a few locations (and dated in only two deposits). In a similar manner, adularia is contemporaneous with Au at Twin Creeks, but Twin Creeks is the only Carlin-type deposit where adularia has been reported. Several other techniques (U-Pb, Re-Os, Sm-Nd) have been used in attempts to date the deposits but with limited success.
I define an evaporite as a salt rock that was originally precipitated from a saturated surface or nearsurface brine by hydrologies driven by solar evaporation (Figure 1.1). This simple definition encompasses a wide range of chemically precipitated salts and includes alkali earth carbonates (Table 1.1). Some workers restrict the term evaporite to those salts formed directly via solar evaporation of hypersaline waters at the earth's surface.

In 1992, 13 companies operated 23 primary aluminum reduction plants. Based on published market prices, the output of primary metal in 1992 was valued at $5.2 billion. Packaging accounted for an estimated 35% of domestic consumption; transportation, 20%; building, 17%; electrical, 9%; consumer durables, 8%; and other uses, 11 %. Aluminum recovered in 1992 from purchased scrap was about 2.6 Mt, of which about 40% came from new (manufacturing) scrap and 60% from old scrap (discarded aluminum products). Aluminum recovered from old scrap was equivalent to about 30% of apparent consumption.
This book is dedicated to curious individuals and explorers of knowledge and technologies that have not been awarded a Nobel prize (yet). It has been written for tinkerers who want to employ tools to analyze the near subsoil (less than 20 m) with what is at hand.
