Mont Terri
Mont Terri (804 m) is one of the mountains of the Jura Mountains range. It is located south of Cornol in the Canton of Jura. The mountain can be located 140 km west of Zurich. A prehistoric site, Mont-Terri Castle, is located on the summit. Geological structure The Mont Terri has an anticline structure and is the northernmost anticline of the folded Jura. The sedimentary rock layers of Jurassic age dip 42° into the direction of SSE. The Mont Terri anticline hosts different tunnel infrastructures. A limestone underground quarry was first exploited by room and pillar mining for the "Fabrique de chaux" of Saint Ursanne until the 1980s. The Mont Terri tunnel (4 068 m length) was excavated and constructed between 1988 and 1998 for the Transjuranne A16 motorway. It consists of one single main tube hosting two circulation ways in opposite direction and one security gallery for emergency interventions and escape route in case of fire. The security gallery of smaller diameter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudrock
Mudrocks are a class of fine-grained siliciclastic sedimentary rocks. The varying types of mudrocks include siltstone, claystone, mudstone, slate, and shale. Most of the particles of which the stone is composed are less than and are too small to study readily in the field. At first sight, the rock types appear quite similar; however, there are important differences in composition and nomenclature. There has been a great deal of disagreement involving the classification of mudrocks. A few important hurdles to their classification include the following: # Mudrocks are the least understood and among the most understudied sedimentary rocks to date. # Studying mudrock constituents is difficult due to their diminutive size and susceptibility to weathering on outcrops. # And most importantly, scientists accept more than one classification scheme. Mudrocks make up 50% of the sedimentary rocks in the geologic record and are easily the most widespread deposits on Earth. Fine sedi ...

Argillaceous Minerals
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2 Si2 O5( OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans since ancient times in agriculture and manufacturing. Properties Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. It is a very common material, and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. Because the individual particles in clay are less than ...

Geotechnical Investigation
Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is called a site investigation. Geotechnical investigations are also used to measure the thermal resistance of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved. Geotechnical investigations are very important before any structure can be built, ranging from a single house to a large warehou ...

Geochemistry
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology. History The term ''geochemistry'' was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838: "a comparative geochemistry ought to be launched, before geognosy can become geology, and before the mystery of the genesis of our planets and their inorganic matter may be revealed." However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. Geochemistry emerged as a separate discipline after ...

Hydrogeology
Hydrogeology (''hydro-'' meaning water, and ''-geology'' meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers). The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably. Hydrogeology is the study of the laws governing the movement of subterranean water, the mechanical, chemical, and thermal interaction of this water with the porous solid, and the transport of energy, chemical constituents, and particulate matter by flow (Domenico and Schwartz, 1998). Groundwater engineering, another name for hydrogeology, is a branch of engineering which is concerned with groundwater movement and design of wells, pumps, and drains. The main concerns in groundwater engineering include groundwater contamination, conservation of supplies, and water quality.Walton, William C. (November 1990). ''Principles of Groundwater Engin ...

Porrentruy
Porrentruy (, fc, Poérreintru , german: Pruntrut) is a Swiss municipality and seat of the district of the same name located in the canton of Jura. Porrentruy is home to National League team, HC Ajoie. History The first trace of human presence in Porrentruy is a mesolithic tool that was found in the back yard of the Hôtel-Dieu. Scattered, individual objects have also been found from the neolithic, the late Bronze Age and the Iron Age. The first known settlement in what became Porrentruy goes back to the Roman era. In 1983, the ruins of a Gallo-Roman temple were discovered in the cemetery on the north of town, and Roman coins were found there. Near the town, a kilometer long (0.6 mile) section of the Augst- Epomanduodurum (now Mandeure) Roman road was discovered. In the back yard of the Hôtel-Dieu the charred remains of a building from the 10th or 11th century were discovered. However, the first historical mention of the name occurs in 1136 as ''Purrentru''.

Delémont
Delémont (; fc, D'lémont; german: Delsberg, ) is the capital of the Swiss canton of Jura. The city has approximately 12,000 inhabitants . History The area of the municipality was already settled in the middle Bronze Age. Fifteen urn burials have been discovered in the municipality. There were late Bronze Age settlements south and west of the modern city. Several Iron Age buildings have been discovered south of town. There is also evidence of a Roman settlement, including a Gallo-Roman mausoleum and a small cache of coins. One or possibly several villas in the area may indicate the existence of a vicus near the town. The first historic mention of the name dates from 736 to 37 as ''Delemonte''. In 1131, the first mention of the German name ''Telsperg'' was recorded. It is also mentioned as Laimunt (1181) and Deleymunt (1225). The name is a combination of the Germanic ''Tello'' or ''Dagili'' with the Latin word ''mons'' for ''mountain''. Since the 7th century, the region bel ...
