Johnson Geo Centre
The Johnson Geo Centre is a geological interpretation centre, within a small park, located on Signal Hill in St. John's, Newfoundland and Labrador, Canada. The museum is named for philanthropist Paul Johnson and opened in 2002. Building Design Most of the centre is located underground, in an excavated glacial formation that shows the exposed bedrock of the hill. The building is designed to take advantage of the geological features of Signal Hill where most of the structure is below ground exposing natural rock formations. The area was originally a peat filled area that was stripped of overburden and a glass-encased structure of 2.5 stories was built atop the excavation. The building was built through the Johnson Family Foundation at a cost of $11 million. The building utilizes a heating and cooling system via six geothermal wells drilled to a depth of 500 feet. Museum Content Visitors travel a 3.7 billion year timeline, exploring themes such as continental drift, glaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with 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. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their Geochronology, absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Museum Of Canada
Digital Museums Canada (DMC; , ''MNC'') is a funding program in Canada "dedicated to online projects by the museum and heritage community," helping organizations to build digital capacity. Administered by the Canadian Museum of History (CMH) with the financial support of the Government of Canada, DMC provides investments of CA$15,000 to $250,000 for audience-engaging online projects by Canadian museums and heritage organizations. History The Digital Museum of Canada was preceded by the Virtual Museum of Canada (VMC), which existed from 2001 to 2021. The VMC was launched by the Canadian Heritage Information Network (CHIN) of the Department of Canadian Heritage as a major collaborative online initiative to allow Canadian museums and heritage organizations to connect with online visitors. In February 2014, the Government of Canada announced its intention to transfer the VMC and the Online Works of Reference to the Canadian Museum of History (CMH). Bill C-31, an ''Act to impl ...

Museums In St
A museum is an institution dedicated to displaying or preserving culturally or scientifically significant objects. Many museums have exhibitions of these objects on public display, and some have private collections that are used by researchers and specialists. Museums host a much wider range of objects than a library, and they usually focus on a specific theme, such as the arts, science, natural history or local history. Public museums that host exhibitions and interactive demonstrations are often tourist attractions, and many draw large numbers of visitors from outside of their host country, with the most visited museums in the world attracting millions of visitors annually. Since the establishment of the earliest known museum in ancient times, museums have been associated with academia and the preservation of rare items. Museums originated as private collections of interesting items, and not until much later did the emphasis on educating the public take root. Etymology The ...

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as ''tuffaceous'' (for example, ''tuffaceous sandstone''). A pyroclastic rock containing 25–75% volcanic bombs or volcanic blocks is called tuff breccia. Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called t ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility. Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock (clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined as grains 2–62 μm in diam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formation (geology)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob ...

Precambrian
The Precambrian ( ; or pre-Cambrian, sometimes abbreviated pC, 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 Latinized 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.

Signal Hill, Newfoundland And Labrador
Signal Hill is a hill which overlooks the harbour and city of St. John's, Newfoundland and Labrador, Canada. The majority of Signal Hill, including Cabot Tower, is designated a National Historic Site. The highest point, Ladies' Lookout, is high. Due to its strategic placement overlooking the Narrows, the only entrance to the harbour, fortifications date back to the mid 17th century. On 12 December 1901, the first transatlantic wireless transmission was received there by Guglielmo Marconi. Adjacent to the National Historic site is the Johnson Geo Centre and Johnson Geo Vista Park. The community of The Battery lies on the slope of the hill overlooking the harbour, and Memorial University of Newfoundland has a campus on the lower slopes, in the former Battery Hotel. History The final battle of the Seven Years' War in North America was fought in 1762 at the Battle of Signal Hill, in which the French surrendered St. John's to a British force under the command of Lieutena ...
