Found 10 records similar to Regional Geochemical Stream Water Sampling
Geochemical analytical data are reported for 123 Cretaceous rock samples from northwestern Alberta collected by Alberta Geological Survey (AGS) staff from 2001 to 2005. The values for one repeat analysis are included (5602R), making a total of 124 analytical records. The results include analyses of 57 mudstone, 29 shale, 13 ironstone, 6 pyrite (float), 5 kimberlite (including one till clast) and 5 sandstone (including one bioclastic sandstone) samples. Geochemical analyses were performed by Acme Analytical Laboratories Ltd. of Vancouver, British Columbia, for a wide range of elements and oxides using the following analytical methods.
Indexes of real expenditure per capita in the United States relative to those in Canada for categories of gross domestic income (GDI), Canada=100, on an International Comparison Project Classification (ICP) basis.
This data set is a geographic information systems (GIS) version of part of the results of Canada-Alberta Mineral Development Agreement project 'Geological mapping, prospecting and sampling of the Southern Alberta Rift.' The data represent elemental analyses of 415 stream sediment samples collected from the study area in 1992. Analytes include: Ag, Cd, Cu, Pb, and Zn by atomic absorption; Ag, As, Au, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, Ir, La, Lu, Mo, Na, Ni, Rb, Sb, Sc, Se, Sm, Sn, Ta, Tb, Te, Th, U, W, Yb, Zn, and Zr by neutron activation; and Hg by cold vapour extraction/atomic absorption. Results show that some of the stream sediments contain higher concentrations of mineral elements than normal.
Samples of rocks during reconnaissance geological mapping by Geological Survey of Canada field parties have been used to estimate the average abundance of some trace elements in the surface crystalline rocks of the Canadian Shield. The preferred values are as follows, in ppm: Ni, 19; Cu, 26; Zn, 60 ; Pb, 18; V, 59; Sc, 12 ; Y, 21; La, 71; Zr, 190 . Regional variations in trace element content of the rocks suggest that Pb is mobile under high grade regional metamorphism but that Ni , Co, Cu, Zn, V, and Scare relatively immobile and tend to be concentrated in rocks of granulite facies. Ni is more abundant and Pb and Zn less abundant in Archean rocks than in Proterozoic rocks.
Geochemical results are reported for a program that compared samples collected from eskers and adjacent till in permanently frozen terrain. Contrasting effects of disturbance on the well- and poorly sorted sediments within the active (seasonally thawed) zone are discussed. Trace element geochemistry of several textural and mineralogical fractions of each sample is reported, compared and explained. A previously known area of copper-nickel mineralization is clearly outlined by anomalies in various fractions of both till and esker samples.
What? Water samples are collected in Cape Breton Highlands National Park in various freshwater lakes and streams. When? Water samples are taken in select park lakes biannually (ie.
2020 DATABASE (Excel): The joint federal-provincial Regional Geochemical Surveys (RGS) have been carried out in British Columbia since 1976 as part of the National Geochemical Reconnaissance (NGR) program to aid exploration and development of mineral resources. The British Columbia Geological Survey (BCGS) maintains provincial geochemical databases capturing information from multi-media surveys. This 2020 release of the most current and complete province-wide geochemical data set collected under the (RGS) program. The database was compiled from 116 original sources with 65,429 samples and about 5 million determinations analyzed using 18 methods in 18 laboratories.
The dataset contains the results of analyses of surface water samples collected by AGS in the summer of 1999. Three lakes, three creeks, one stream and two rivers were sampled as part of a water sampling program carried out by AGS in the Athabasca Oil Sands in-situ area of Alberta. This area extends from approximately 55.34 degrees north latitude to 55.96 degrees north latitude, and 110.5 degrees west longitude to 111.8 degrees west longitude. The datum is NAD83.
Terra Nova National Park employs a kicknet sampling procedure to monitor the species richness and relative species abundance of stream invertebrates. Streams chosen for sampling are randomly selected within second order watersheds.
In order to assess long-term changes in streams Thousand Islands NP monitors their water quality yearly in July. Samples are analyzed for multiple parameters including: total phosphorus, ammonium, nitrate, turbidity, and specific conductivity.
