Marcel Alexandre Bertrand
Marcel Alexandre Bertrand (2 July 1847 – 13 February 1907) was a French geologist born in Paris. He was the son of mathematician Joseph Louis François Bertrand (1822–1900), and son-in-law to physicist Éleuthère Mascart (1837-1908). He studied at the École Polytechnique, and beginning in 1869 he attended the Ecole des Mines de Paris. From 1877 he carried out geological mapping studies of Provence, the Jura Mountains and the Alps. In 1886, he became an instructor at the École Nationale Supérieure des Mines, and in 1896 became a member of the Académie des sciences. Bertrand, a founder of modern tectonics, originated an orogenic "wave theory" of mountain-building and introduced the nappe hypothesis (). His wave theory described a build-up of massive folds of earth taking place over successive geological eras, called the Caledonian, Hercynian and Alpine periods of orogeny. Bertrand later added a fourth event called the Huronian orogeny, which took place 2400 to 2100 mill ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Caledonian Orogeny
The Caledonian orogeny was a mountain-building era recorded in the northern parts of the British Isles, the Scandinavian Mountains, Svalbard, eastern Greenland and parts of north-central Europe. The Caledonian orogeny encompasses events that occurred from the Ordovician to Early Devonian, roughly 490–390 million years ago ( Ma). It was caused by the closure of the Iapetus Ocean when the continents and terranes of Laurentia, Baltica and Avalonia collided. The orogeny is named for Caledonia, the Latin name for Scotland. The term was first used in 1885 by Austrian geologist Eduard Suess for an episode of mountain building in northern Europe that predated the Devonian period. Geologists like Émile Haug and Hans Stille saw the Caledonian event as one of several episodic phases of mountain building that had occurred during Earth's history. Current understanding has it that the Caledonian orogeny encompasses a number of tectonic phases that can laterally be diachronous. The n ...

This edition was started on 23 March 2001, two months after the official creation of Wikipedia. It has articles as of , making it the -largest Wikipedia overall, after the English-, Cebuano-, Swedish- and German-language editions, the largest Wikipedia edition in a Romance language. It has the third-most edits, and ranks 6th in terms of depth among Wikipedias. It was also the third edition, after the English Wikipedia and German Wikipedia, to exceed 1 million articles: this occurred on 23 September 2010. In April 2016, the project had 4657 active editors who made at least five edits in that month. In 2008, the French encyclopaedia '' Quid'' cancelled its 2008 edition, citing falling sales on competition from the French edition of Wikipedia.

Saint-Gervais-les-Bains
Saint-Gervais-les-Bains () is a commune in the Haute-Savoie department in the Auvergne-Rhône-Alpes region, southeastern France. The village is best known for tourism and has been a popular holiday destination since the early 1900s. It has of pistes, the third largest domain exclusively in France, and is one of the least busy ski areas of its size. In 1892, two hundred people were killed when a water pocket in a glacier above the town suddenly burst open and caused flooding. Tourism St Gervais les Bains (also referred to as St Gervais or St Gervais Mont Blanc) is a traditional French market and spa town, not a recently purpose built resort, and so has a significant year round population, rather than just seasonal and is full of historical buildings giving it the traditional charm much sought after in the Alps. In winter, the main draw is of course snow sports, and the resort has a multi-national client base. It is increasing in popularity among British holiday-makers. The sum ...

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards. The Precambrian fossil ...
