Sil­ver - min­er­al­o­gy, min­ing and his­to­rySilver and silver minerals are amongst the most desirabe objects since the beginning of mineral collecting. Silver wires and curls from Kongsberg and Freiberg are the coronation of each mineral collection. Beautiful pyrargyrites and proustites enhance each collector's heatbeat.

However, silver is not only the essence of high-end collecting but has contributed essentially to the history of mankind. Uncountable remain the millions of greek and phenician slaves, middle age european miners and millions of indios who have left their lives for silver.

Silver is one of the seven metals known since thousands of years, already been mentioned in the bible. Mountains of slag in Asia Minor, Arabia and on the agaen islands prove technologies to produce silver from lead ore; knowledges people had been acquainted with since at least 4.000 year B.C. Since the antiquity silver had been used to make finery and ornaments, however, most of this metal was used to stamp coins. The monetary system of many countries was based on silver; the one, who owned silver, was able to finance wars. One of the main pillars of power of Athens, Rome, the Phenicians, the church, the kings and queens of Castilia, the Austrian house of Habsburg and, last not least, of the Americans had been their control over the richest silver mines and the wars, which they made by paying their soldiery with silver coins.

San Ti­m­o­teo Mine at La Union min­ing area, Mur­cia, SpanienGypsum needels and blue Baryte have made this mine known for mineral collectors. A recent report from Sept. 2012 shows that good finds are still possible. To visit this mine is relatively easy. The evacuation of the gypsum needels on the other hand is more difficult. Unfortunately, vandals have left their mark, but read and see it yourself. A report by Stefan Schorn. (Article in German)

Flu­o­reszenz von Min­er­alienDie Fluoreszenz wurde zum ersten Mal beim Fluorit - einem Calcium-Fluorid - beobachtet (daher auch die Bezeichnung). Fluoreszenz beginnt sofort mit der Anregung durch die Lichtquelle und endet auch mit ihr (im Gegensatz dazu ist Phosphoreszenz ein Nachleuchten). Unter Tageslicht-Fluoreszenz versteht man eine Fluoreszenz, die durch den UV-Anteil im natürlichen Licht verursacht wird und z.B. manche Fluorite unter natürlichem bzw. künstlichen Licht andersfarbig erscheinen lässt.

Mag­ne­sitw­erk - Hoch­filzen1908 Entdeckung der Magnesitlagerstätte auf der Millstätter Alpe in Kärnten durch den Bergbauingenieur Josef Hörhager. Der Deutsch-Amerikaner Emil Winter erwirbt die Schürfrechte und gründet die Austro-American Magnesite Group, die in Radenthein mit der Errichtung eines beachtlichen Magnesitwerkes begann.
1925 wurden die Magnesit-Lagerstätten am Weißenstein und der Rettenwand bei Hochfilzen in Tirol entdeckt.
1928 sicherte sich die Austro-American Magnesite Group die Abbaurechte dafür und fusionierte mit der Allgemeinen Automobil G.m.b.H. in Wien zur Austro-American Magnesite Company. Im gleichen Jahr wurde mit dem Abbau im Untertagebetrieb begonnen.
bis circa 1930 konnte man von einem österreichischen Magnesit Monopol sprechen... Ein Beitrag von Michael Kommer

In­di­ca­tor stoneA Scandinavian indicator stone is a glacial erratic composed of a characteristic rock type derived from a small known source area in Scandinavia. This term not only applies to igneous and metamorphic rocks but also to some sedimentary rocks. The Jotnian Sandstone and most of the Palaeozoic limestones, and the Old Red Sandstone are not included in the definition, although the presence of these and other rocks provide some evidence about the source area(s) of erratics and should certainly not be neglected in a stone count. In all cases we recommend including the whole assemblage of erratics/stones in such account. This makes it possible to use several methods of Interpretation. However, it should be pointed out that the practise used in the past, whereby each researcher had her/his own method of interpreting stone counts, has proved to be unsatisfactory. We demonstrate on the bases of over 2000 counts of indicator stones that we have carried out on assemblages mostly from Lower Saxony and Schleswig-Holstein, but also from other N.German states and neighbouring countries, that the TGZ method (LÜTTIG 1958) yields the most reliable results. In addition to this method, the sources of individual indicator stones may be plotted on a so-called circle map and can be integrated with possible source data and the relative frequencies of other erratics in the assemblage. Some rock types are more suitable as indicator stones then others. It is unwise to use clearly unsuitable rock types; this would considerably reduce the reliability of the method and lead to erroneous results.

Ore leach­ing (in ger­man)The metal extraction by ore leaching (mostly copper) was about 1,000 years BC. known in the Mediterranean, but there are also barely no written records. The in the Middle Ages and in the following Renaissance well-known different procedures were first described in detail by Georg Agricola 1556 in his book "De Re Metallica Libri XII".

Kreide / Cre­ta­ceousKreide oder Kreidezeit nennt man die Zeitperiode der geologischen Zeitachse, die den obersten Teil des Mesozoikum bildet. Als solche folgt sie dem Jura und beginnt vor ca. 144,5 Mio. Jahren. Die Kreide endet vor ca. 65,5 Mio. Jahren mit dem Übergang zum Paläozän, dem ältesten Teil des Paläogen. Die Kreide wird grob in Unterkreide und Oberkreide geteilt. Diese gliedern sich wieder in weitere Stufen. Für eine genaue Unterteilung der Kreide siehe die Geologische Zeittafel.
