14-627: The AGS is the official provincial geological survey of Alberta. It operates under the guiding principles of the Canada Intergovernmental Geoscience Accord, which identifies the provincial survey as being the principal steward, resident authority, and principal investigator for public geoscience. AGS is responsible for describing the geology and resources in the province and provides information and knowledge to help resolve land use, environmental, public health, and safety issues related to geosciences. Geological surveys exist at

28-518: A cross section can include rock units , faults , topography , and more. They often accompany geologic maps , complementing the overhead view with a side-on view, which can help to visualize the three-dimensional structure of the region and clarify the relationships between features. A cross section is drawn as a vertical map , as if the ground had been cut open and exposed along a given line. Various lines, colors, patterns, and symbols are used to represent different rock sections and features. Because

42-430: A geological survey. Examples include: This geology article is a stub . You can help Misplaced Pages by expanding it . Cross section (geology) A cross section or cross-section , in geology , is a diagram representing the geologic features intersecting a vertical plane , and is used to illustrate an area's structure and stratigraphy that would otherwise be hidden underground. The features described in

56-562: Is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model . Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms , to intrusive methods, such as hand augering and machine-driven boreholes , to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery . Such surveys may be undertaken by state, province, or national geological survey organizations to maintain

70-620: The Alberta Research Council (ARC). In the late 1990s, AGS was transferred to the Alberta Energy and Utilities Board (a predecessor to the AER) to provide geoscience expertise to support the regulatory process, to provide necessary geoscience information and knowledge to the Government of Alberta, and to fulfill the need for unbiased, credible public geoscience information. AGS resides within

84-774: The Geological Atlas of the Western Canada Sedimentary Basin . Subsurface maps typically depict the three-dimensional form of geological surfaces by means of contours and cross sections. Computer-based models are increasingly used to provide more comprehensive information storage and greater flexibility of presentation. In the United States, the 50 state surveys are coordinated by the Association of American State Geologists . Some examples of national geological surveys are: Individual states or provinces may also have

98-522: The geology of Alberta needed by government, industry and the public for earth-resource stewardship and sustainable development in Alberta. Geological processes, like sedimentation , glaciation , mountain building and landslides , have shaped Alberta and provided Albertans with a wealth of Earth resources. Mapping and documenting these processes are key to understanding Alberta's current and untapped resources. Geological survey A geological survey

112-581: The Legislative Assembly of Alberta the first government report on the mineral resources of the province. Dr. Allan reported on 18 different mineral resources known to occur in the province at that time. That report marks the beginning of AGS. The Alberta Geological Survey was created in 1921, by Order in Council of the Alberta government, as a core part of the Scientific and Industrial Research Council, later

126-516: The founding of the University of Alberta . Dr. Henry Marshall Tory , then president of the university, appointed Dr. John Allan to initiate the teaching of geology and establish a new Geology Department at the U of A. Dr. Allan took up the challenge and stayed on as Professor of Geology for nearly 40 years, with 37 of those years as head of the Geology Department. In 1920, Dr. Allan delivered to

140-523: The geological inventory and advance the knowledge of geosciences for the benefit of the nation. A geological survey map typically superimposes the surveyed extent and boundaries of geological units on a topographic map, together with information at points (such as measurements of orientation of bedding planes) and lines (such as the intersection of faults with the land surface). The maps and reports created by geological survey organisations generally aim for geographic continuity and completeness in establishing

154-462: The length of the studied area is often much greater than the depth, the diagram's scale can be vertically exaggerated to emphasize the depth or height of features and make them more visible. The plane a cross section illustrates is typically labeled as a line on a map of the surrounding region. Cross sections are made by interpreting and extrapolating a broad range of information about a region's geological characteristics. This can include data from

168-677: The provincial regulator to this day, providing geoscience support for Alberta's regulatory process. The manager of the AGS represents Alberta on the National Geological Surveys Committee, which governs the implementation of the Intergovernmental Geoscience Accord and fosters cross-jurisdictional survey co-operation in Canada. The specific mission of the AGS is to provide data, information, knowledge and advice about

182-621: The provincial/territorial and federal levels of government in Canada . The complementary roles and responsibilities of provincial geological surveys and the federal survey, the Geological Survey of Canada (GSC), are defined in the Intergovernmental Geoscience Accord, which was signed by Ken Hughes , Alberta Minister of Energy, at Canada's Annual Energy and Mines Ministers' Conference in September, 2012. The roots of AGS go back to 1912, one year after

196-480: The spatial patterns of near-surface rock units. The map may include cross sections to illustrate the three-dimensional interpretation. Subsurface geological and geophysical maps, providing limited coverage of deeper geology (known, for example, from drilling for oil or gas), are maintained internally by major oil companies and regulators. Some geological survey organisations have collaborated with them to include subsurface geology in their systematic surveys, for example,
