Gros Caillou
Gros Caillou (literally "big pebble") is a landmark of the French city of Lyon in the neighborhood Croix-Rousse. The rock's mineralogical composition suggests it is a glacial erratic, and would have been transported from the nearby Alps by slowly moving glaciers. Localization Originally, Gros Caillou was located at the end of Boulevard de la Croix-Rousse, constructed in 1865, and the boundary between the 1st arrondissement (Croix-Rousse hill) and the 4th arrondissement (Croix-Rousse plateau). Until it was annexed in 1852, the Croix-Rousse Plateau was a separate city. Thus, the location of Gros Caillou at that intersection became a unifying symbol. At the beginning of the 21st century, an underground parking lot and green area took over this area and Gros Caillou was relocated 30m into the 1st arrondissement. History Gros Caillou is a metamorphic Triassic quartzite, typical of the alpine regions of Haute-Maurienne and Haute Tarentaise. It is rock that was displaced by glaci ...

Croix-Rousse
La Croix-Rousse is a hill high in the city of Lyon, France, as well as the name of a neighborhood located on this hill. The neighborhood is divided into les pentes (slopes, belonging to the city's 1st arrondissement) and le plateau (atop the hill, part of the 4th arrondissement). This zone is served by Metro line . With 18th century architecture, including unique dwellings for labourers, La Croix-Rousse was inscribed on the UNESCO World Heritage List in 1998 (along with other districts in Lyon) to protect Lyon's long history as an important European city. Names and etymology The name "La Croix-Rousse" ('the russet/red cross') comes from a reddish-brown stone cross erected there in the 16th century. In Lyon, La Croix-Rousse is nicknamed ''la colline qui travaille'' ('the hill that works') in contrast to the better-known hill to the southwest, Fourvière, which is known as ''la colline qui prie'' ('the hill that prays').

Glacial Erratic
A glacial erratic is glacially deposited rock differing from the type of 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 Big Rock () 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 they are thereby one of a series of indicators which mark the path of prehistoric 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. This allows quantification of the extent of glacial flooding resulting from ice dam failure which release the waters stored in proglacial lakes such as Lake Missoula. Erratics ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains 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 is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boulevard De La Croix-Rousse
is a boulevard that marks the border between the 1st and the 4th arrondissements of Lyon, in the neighborhood Croix-Rousse. Location The boulevard runs east–west and is the border between the 1st and 4th arrondissements and the neighborhoods and Plateau de la Croix-Rousse. History The Croix-Rousse ramparts were reconstructed in 1834 on the remains of 16th century ramparts, which had been demolished during the revolt of Lyon against the National Convention in 1793. In 1852 when Croix-Rousse became a quarter of Lyon the ramparts were destroyed to facilitate the integration of the new quarter. was constructed on the former site of these fortifications in 1865. A town hall was built and trees were planted along the boulevard at this time. The Croix-Rousse Market and the Vogue fair (formerly the Parish Festival of the church of Saint-Denis) began to take place on the boulevard soon after its construction. From 1863 to 1914, the boulevard functioned as a single-lane roa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Maurienne
Maurienne ( frp, Môrièna) is one of the provinces of France, provinces of Savoy, corresponding to the arrondissement of Saint-Jean-de-Maurienne in France. It is also the original name of the capital of the province, now Saint-Jean-de-Maurienne. Location The Maurienne valley is one of the great transverse valleys of the Alps. The river which has shaped the valley since the last glaciation is the Arc (Savoie), Arc. The valley begins at the village of Écot (in the ''Communes of France, commune'' of Bonneval-sur-Arc), at the foot of the Col de l'Iseran, and ends at the confluence of the Arc and the Isère (river), Isère in the ''commune'' of Aiton, Savoie, Aiton. The mountains on the southern side are the Dauphiné Alps and the Cottian Alps. On the northern side are the part of the Graian Alps known as the Vanoise Massif, Vanoise.

Riss Glaciation
The Riss glaciation, Riss Glaciation, Riss ice age, Riss Ice Age, Riss glacial or Riss Glacial (german: Riß-Kaltzeit, ', ' or (obsolete) ') is the second youngest glaciation of the Pleistocene epoch in the traditional, quadripartite glacial classification of the Alps. The literature variously dates it to between about 300,000 to 130,000 years ago and 347,000 to 128,000 years ago. It coincides with the glaciation of North Germany. The name goes back to and who named this cold period after the river in Upper Swabia in their three-volume work ' ("The Alps in the Ice Age") published between 1901 and 1909. Boundaries and division The Riss glaciation was defined by Penck and Brückner as the Lower (''Niedere'') or Younger Old Moraines and Old Terminal Moraines High Terraces (''Jüngere Altmoränen und Alt-Endmoränen-Hochterrassen''). The type locality lies near Biberach an der Riß where the end of the northeastern Rhine Glacier stood. Results gained from over a century of resea ...
