It contains all the linear landform features such as eskers, flutings and melt-water channels, etc. Part of the dataset was complied by air photo interpretations and followed by random ground-truthing (NTS73M) by AGS geologists. Dataset was then merged with other existing surficial geology maps (NTS 74D and 84A). Analysis of surficial geological materials, aspects of local relief, and morphological characteristics of surface landforms form an integral component in the evaluation of recharge fluxes to regional groundwater flow systems. To assist in the evaluation of groundwater recharge, terrain analysis maps were constructed in GIS format at a scale of 1:50 000 and 1:250 000 for most of the study area, including all of map NTS 73M (Winefred), the southern three-quarters of map NTS 74D (Waterways), and the southeast part of NTS 84A (Algar). Surficial geology maps of the portion of the study area that lies within map area NTS 83P (Pelican) were published by the surficial geology group in the Minerals Section of the Alberta Geological Survey. The terrain analysis maps in NTS 73M and NTS 84A were constructed almost entirely from the interpretation of 1:60 000 scale aerial photographs, supplemented with only a minor amount of ground verification. Terrain analysis maps in the area defined by NTS 74D were constructed from both aerial photograph analysis as well as from published surficial geology information (Bayrock, L. and Reimchen, T., 1973). Classification of the terrain was based on interpretations of landform types, tonal reflections of surface materials, differences in vegetative cover, and differences in drainage patterns and characteristics, all of which can be identified on aerial photographs. It is for this reason that the maps are referred to as aerial photograph terrain analysis maps, rather than surficial geology maps, which generally have a greater amount of ground verification. The reader is therefore cautioned that a higher degree of uncertainty exists regarding the information depicted on the terrain analysis map, compared to that on a surficial geology map.2020-04-30T03:25:56.944076+00:00https://open.alberta.ca/dataset/9ccff2af-10f7-4616-9ccc-429bf4039821Surficial Materials of the Athabasca Oil Sands (in Situ) Area, Northeast Alberta (GIS data, polygon features)2024-03-30T02:49:10.182399+00:00The surficial material dataset was developed as part of the Western Economic Partnership Agreement (WEPA) project covering all of NTS 73M, the southern three-quarters of 74D and southeast part of 84A. Part of the dataset was compiled by airphoto interpretations and followed by random ground-truthing by AGS geologists (NTS 73M). The dataset was later merged with other existing surficial geology maps (74D and 84A). The mapping scheme chosen for the 1:50 000 scale terrain classification is a variant of the scheme used in Alberta Geological Survey Bulletin 57 to map the surficial geology of the Sand River area (Map 178), NTS 73L, directly south of the study area. In this terrain classification scheme, each map unit includes a component of genesis, morphology and relief. Where available, additional information regarding the properties of the genetic unit was included as a genetic modifier. For example, the map unit 'sMh1' denotes hummocky (h), low relief (1), sandy (s) moraine (M). Genesis of geological material is considered to be the primary component of the map unit thus colours on the map depict differences in genesis. In the above example, the map unit colour would correspond to the legend colour chosen for moraine (M). An attempt has been made to reclassify the surficial geological units depicted in the surficial geology map of area NTS 74D (Map 148) using this mapping scheme, without significantly changing the polygon shapes of that previous work.2020-04-30T03:25:58.971955+00:00https://open.alberta.ca/dataset/29430344-0807-4b40-971d-4ad6f207427bCompilation of In Situ Stress Data from Alberta and Northeastern British Columbia (tabular data, tab delimited)2024-03-30T02:51:16.623462+00:00This digital dataset is the compilation of an analysis of the in situ stress regime in several regions of Alberta and northeastern British Columbia conducted by Dr. Sebastian Bell under a contract with the Alberta Geological Survey from 1999 to 2004. The dataset includes both new and previously published estimates for vertical stress gradients, minimum horizontal stress gradients, and stress orientation. Understanding the state of stress in the subsurface has always been important in the development of energy resources. The recent development of unconventional oil sand and low permeability hydrocarbon deposits, waste fluid disposal, greenhouse gas sequestration, and potential geothermal energy extraction all require knowledge of the state of stress to operate safely and economically. A lack of understanding of the state of stress in a given project area has the potential to negatively affect the economics of such projects and may expose operators to increased liabilities. Regional-scale studies of the stress regime indicate that in southern and central Alberta the vertical stress (Sv) is the largest principal stress. The Sv magnitude is determined from the overburdened load and is calculated by integrating the bulk density log from ground surface to the depth of interest. This dataset contains 724 vertical stress gradient measurements from 126 wells in Alberta. The minimum horizontal stress (Shmin) can be evaluated using a variety of tests. While leak-off tests and fracture breakdown pressures have been used in the past for estimating the magnitude of the Shmin, mini-fracture tests (also known as DFITS) are currently considered a more accurate and consistent method. This dataset includes only mini-fracture test data, consisting of 106 minimum horizontal stress gradient measurements in 83 wells. Alberta was one of the first regions in the world where stress mapping began, originating in the pioneering 'borehole breakout' developments of Dr. Bell from the Geological Survey of Canada in Calgary and Dr. Gough from the University of Alberta. The Shmin orientations can be determined from borehole breakouts, which are spalled cavities that occur on opposite walls of a borehole. This dataset contains 214 stress orientation measurements from 133 wells.2020-04-30T04:11:54.712665+00:00
