Glacial Erratic On Wolności Square In Racibórz
The glacial erratic on Wolności Square is a glacial erratic composed of granite (with numerous inclusions) from the Ice age, located on Wolności Square in Racibórz. It is the largest of all erratics found in the and the largest commemorative erratic in the Silesian Voivodeship and all of Silesia. In 1960, it was designated a natural monument. Characteristics The glacial erratic is composed of granite, featuring red feldspar and quartz. It weighs 42.5 tons, has a volume of 16.5 m³, a length of 3.25 m, and a height of 2.25 m. It is situated in the middle of Wolności Square on plot number 843/175. Two hiking trails pass by the erratic: the yellow and the red . History This boulder originated from Scandinavia and was transported to the by glaciers during the Mindel glaciation. It was discovered in 1927 in a sand pit owned by Karol Popelli in Wojnowice. The boulder was fully exposed in 1929, and in 1934, following the advice of a local teacher, Alfons Nentwig, it was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racibórz
Racibórz (, , , ) is a city in Silesian Voivodeship in southern Poland. It is the administrative seat of Racibórz County. With Opole, Racibórz is one of the historic capitals of Upper Silesia, being the residence of the Duchy of Racibórz, Dukes of Racibórz from 1172 to 1521. Geography The city is situated in the southwest of the voivodeship on the upper Oder river, near the border with the Polish Opole Voivodeship and the Czech Republic. The Racibórz Basin (''Kotlina Raciborska'') forms the southeastern extension of the Silesian Lowlands, surrounded by the Opawskie Mountains in the west (part of the Eastern Sudetes), the Silesian Upland in the north, and the Moravian Gate in the south. The town centre is located about southwest of Katowice and about southeast of the regional capital Wrocław. As of 2019, the city has a population of approximately 55,000 inhabitants. From 1975 to 1998, it belonged to Katowice Voivodeship. History Until the end of the 5th century AD, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mindel Glaciation
The Mindel glaciation (, also ''Mindel-Glazial'', ''Mindel-Komplex'' or, colloquially, ''Mindel-Eiszeit'') is the third youngest glacial stage in the Alps. Its name was coined by Albrecht Penck and Eduard Brückner, who named it after the Swabian river, the Mindel. The Mindel glacial occurred in the Middle Pleistocene; it was preceded by the Haslach-Mindel interglacial (often regarded as part of Günz) and succeeded by the Mindel-Riss interglacial ( Holstein interglacial). The Mindel glaciation is commonly correlated with the Elster glaciation of northern Europe. The more precise timing is controversial since Mindel is commonly correlated to two different marine isotope stages, MIS 12 (478–424 thousand years ago ) and MIS 10 (374–337 thousand years ago). This ambiguity is much related to the correlation problem described in more detail in the article ' Elster glaciation'.

Glacial Erratics
A glacial erratic is a glacially deposited rock (geology), rock differing from the type of country rock (geology), rock native to the area in which it rests. Erratics, which take their name from the Latin word ' ("to wander"), are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Okotoks Erratic, Big Rock (16,500 metric tons) in Alberta. Geologists identify erratics by studying the rocks surrounding the position of the erratic and the composition of the erratic itself. Erratics are significant because: *They can be transported by glaciers, and are thereby one of a series of indicators which mark the path of prehistoric Glacial motion, glacier movement. Their lithographic origin can be traced to the parent bedrock, allowing for confirmation of the ice flow route. *They can be transported by ice rafting, which allows quantification of the extent of glacial flooding resulting from ice dam failure ...

Opole
Opole (; ; ; ) is a city located in southern Poland on the Oder River and the historical capital of Upper Silesia. With a population of approximately 127,387 as of the 2021 census, it is the capital of Opole Voivodeship (province) and the seat of Opole County. Its metropolitan area was home to 146,522 inhabitants. It is the largest city in its province. Its history dates to the 8th century, and Opole is one of the oldest cities in Poland. An important stronghold in Poland, it became a capital of a Duchy of Opole, duchy within medieval Poland in 1172, and in 1217 it was granted city rights by Duke Casimir I of Opole, the great-grandson of Polish Duke Bolesław III Wrymouth. During the Medieval Period and the Renaissance, the city was known as a centre of commerce; several main trade routes intersected here, which helped to generate steady profits from transit trade. The rapid development of the town was also caused by the establishment of a seat of regency in Opole in 1816. The fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kietrz
Kietrz (; ) is a town in Głubczyce County, Opole Voivodeship, in southern Poland, near the border with the Czech Republic. As of 2019, it has a population of 6,005. History It was granted town rights in 1321. During World War II, in 1941, Nazi Germany established the Stalag 338 and Stalag 348 prisoner-of-war camps for Polish and French POWs, which, however, were soon relocated to Kryvyi Rih and Rzeszów, respectively. From 1942 to 1945, the Germans operated a '' Polenlager'' forced labour camp for Poles in the town. In January 1945, a German-conducted death march of prisoners of the Auschwitz concentration camp and its subcamps passed through the town.

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Feldspar
Feldspar ( ; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust and 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Etymology The name ''feldspar'' derives from the German , a compound of the words ' ("field") and ("flake"). had long been used as the word for "a rock easily cleaved into flakes"; was introduced in the 18th century as a more specific term, referring perhaps to its comm ...

Natural Monument
A natural monument is a natural or cultural feature of outstanding or unique value because of its inherent rarity, representative of aesthetic qualities, or cultural significance. They can be natural geological and geographical features such as waterfalls, cliffs, craters, fossil, sand dunes, rock forms, valleys and coral reefs. Locations important to faith groups may be considered natural monuments. Archeological and historical sites linked to the natural environment are also included, such as cave art. This is especially true when relevant to the land of Indigenous Peoples. Protections Under the International Union for Conservation of Nature and Natural Resources guidelines, natural monuments are level III, described as: :"Areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine cavern, geological feature such as a cave or even a living feature such as an ancient grove. They are generally quite small protected areas and often ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
