The Mackenzie Delta is a large fine‐grained delta deposited in a cold arctic setting. subaerial delta plain is characterized by an anastomosing system of high‐sinuosity channels and extensive thermokarst lake development. This region is greatly influenced by the annual cycle of seasonal processes including winter freezing of sediments. His name first appears in the Mackenzie River journals in , as he was on his way out from Great Bear Lake with the returns for Fort Chipewyan. Alexander McKenzie the Emperor had the charge of the district that season, while Clarke served as his assistant at Great Bear Lake. The season of was McKenzie’s last.

Lake Mackenzie (Red River Basin) Lake Mackenzie, also known as Mackenzie Reservoir, is located about nine miles northwest of Silverton in Briscoe County, Texas on Tule Creek, a tributary of the Red River. The reservoir extends into Swisher County and has a drainage area of square miles.
The Mackenzie River basin is the 10 th largest river basin in the world (MRBB ), extending over 20° of longitude and 15° of latitude from the Rocky Mountains to the Arctic lowlands. The basin includes numerous different ecozones and landforms (MRBB ; see the images on the right). These images show a segment of the Mackenzie River about 1, kilometers (1, miles) upstream from the delta, where the river originates at Great Slave Lake in Canada’s Northwest Territories. The Operational Land Imager (OLI) on Landsat 8 captured natural-color views of the lake .

The mining and use of copper by prehistoric people on Michigan’s Keweenaw Peninsula is one of the oldest examples of metalworking. We analyzed the concentration of lead, titanium, magnesium, iron, and organic matter in sediment cores recovered from three lakes located near mine pits to investigate the timing, location, and magnitude of ancient copper mining by: Copper Content of Lake Sediments Bear-Slave Operation - District of MackenzieGeological Map of Canada Series, n.
map 3 Sheet 3, scalaGEOLOGICAL SURVEY OF CANADA Ubicazione Carta: Canada. The sediments of Torch Lake, located in Houghton County, MI, USA, have been impacted by copper mining activity. Remediation of the site has focused on immobilizing shoreline tailing deposits.
However, a large amount of copper remains in the mining-sourced sediment, and high copper concentrations persist in surface sediments. This study analyzes sediment core and sediment trap.

There are three main sources of minerals in lake sediments (Fig. 1): (1) detrital minerals from the catch-ment, which are transported into the lake by rivers and streams, (2) dust deposition.

Large grooves up to 33 m wide and m long have been inscribed in soft unconsolidated lake bottom sediments at Great Slave Lake, NWT. The grooves are probably formed by wind-driven ice floe gouging during each spring breakup.
Smaller grooves having a boulder at one end were formed by boulders pushed by floating lake ice. where copper exceeded the guideline more often since than it did in the s and 70s (Figure 7–3). Why is it happening. Much of the sediment carried in the Mackenzie River originates in the mountains of the Liard sub-basin or is carried downstream by mountain rivers draining the Mackenzie Mountains that lie west of the.
Lake - Lake - Sediments and sedimentation: Lake sediments are comprised mainly of clastic material (sediment of clay, silt, and sand sizes), organic debris, chemical precipitates, or combinations of these.
The relative abundance of each depends upon the nature of the local drainage basin, the climate, and the relative age of a lake. The sediments of a lake in a glaciated basin, for example. A meta-analytical approach is used to better understand controls on As distribution in lake sediments within a km radius of historic mineral processing activities.
