Ge­o­log­i­cal Por­trait - The AlpsThe Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately 1,200 km across eight Alpine countries from Austria and Slovenia in the east, Switzerland, Liechtenstein, Germany, and France to the west, and Italy and Monaco to the south. The Caucasus Mountains are higher, and the Urals longer, but both lie partly in Asia. The Alps were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at 4,810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4,000 m known as the "four-thousanders".

Al­ten­berg Tin MineThe Altenberg tin mine is well known for its huge surface break left by the mining activities. Among mineral collectors the mine is famous as well for its unique Pycnite deposit, a variety of topaz occurring in massive columnar aggregates up to a length of 30 cm.

The mining started in 1440 and continued, with several ups and downs and some total shut-down periods, until 1991. The mining activities aimed for a plutonic granite body (350 to 400 metre in diameter and hydrothermally mineralized mainly with cassiterite and smaller amounts of wolframite, molybdenite, arsenopyrite, bismuth and others) and managed to extract a total sum of 37 million tons of ore. The huge surface break, called "The Altenberger Pinge", is the result of several roof collapses caused by excessive ore excavation and later on the continued drawing of caved material from the bottom of the fracture zone.

Collectible minerals were rare and small, so the Altenberg tin mine became never as famous as the Freiberg or Ehrenfriedersdorf districts, but its unique geology and mining technology made it quite interesting and worth a closer look.

Min­er­alien­por­trait GipsDer Gips und seine große Verwendbarkeit zu plastischen Anwendungen, zur Innenraumgestaltung und als (kalkhaltiger) Gipsmörtel waren schon seit dem Altertum bekannt. In den Keilschriften der Sumerer und Babylonier finden sich Hinweise für die Verwendung von Gips, ebenso in Jericho (6000 v. Chr.). Ab 3000 v. Chr. wurde in Uruk und später in Ägypten Gips auch als Mörtel verwendet, dem Kalk oder Steine als Verunreinigung oder zur Streckung beigemengt waren, u.a., um die Blöcke der Sphinx (2700–2600 v. Chr.) sowie der Großen Pyramide von Gizeh in Form kalkhaltiger Gipsmörtel zu verbinden, bzw. zu verfugen. Der Mörtel der großen Cheops-Pyramide besteht zu 83 Proz. aus Gips. Auch lichtdurchlässige Scheiben aus Alabaster waren bei den Ägyptern bekannt.

Die minoische Kultur verwendete Gipsmörtel und Alabaster anstatt von Marmor als Fußboden oder Wandbelag und als Baustein (Palast von Knossos, 2100–1800 v. Chr. und Palast von Phaistos) und der griechische Naturforscher Theophrastos von Eresos beschrieb in einer Abhandlung die Herstellung von Gips. In Griechenland wurde Gips wegen seiner leichten Bearbeitbarkeit auch für Bauornamente an den Häusern genutzt. Der griechische Geograph Herodot (490/480 - 424 v.Chr.) erzählt von den Äthiopiern, daß sie ihre getrockneten Leichname übergipsten und schön anmalten. Der römische Architekt Vitruv (1. Jh. v.Chr.) und Plinius d.Ä. (23 - 79 n.Chr.) sprechen von der Benutzung des Gipses zu Bauzwecken, und letzterer erzählt, daß der griechische Bildhauer Lysistratos (2. Hälfte des 4. Jh. v.

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.

Min­er­al por­trait Baryt (in ger­man)In the late Middle Ages massive amount of Baryt which phosphoresced when it was gently heated, were discovered in Italy. This stone was named after its place of discovery "Pietra fosforica di Bologna" (phosphorescent Bologna stone) and was of great interest to alchemists. Although the name baryte has been assigned centuries later, it may be assumed that the Bologna stone is the first description in the literature. A portrait about this famous mineral by Peter Seroka.

Cop­per - one of the old­est me­t­als of mankindCopper was one of the first metals ever extracted and used by humans, and it has made vital contributions to sustaining and improving society since the dawn of civilization.
The metal and its alloys have been used for thousands of years. Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum.

The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a result, copper was important to early humans and continues to be a material of choice for a variety of domestic, industrial, and high-technology applications today.

Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite and malachite and have been widely used historically as pigments. ... a contribution by Peter Seroka
