QUATERNARY GEOLOGY OF THE ATLIN AREA (1041V/llW, 12E)

چکیده
This paper repom on the preliminary results of an investigation of the Quaternary and placer geology of the Atlin mining district in northwest British Columbia. The area was selected for study because it supports the second largest placer mining industry in the province and has a long history of placer gold production. In addition, dwindling reserves in recent :years have resulted in the shutdown of major mining operations such as the Queenstake mines on Spruce and Pine creeks. The Atlin area also offers good exposure of Pleistocene gold-hearing strata as well as dating control provided by interhedded basalts. Gold production from the district, recorded for the SO year period after discovery in 1897, was approximately 20 000 kilograms (Holland,1950). The locations of active mechanized mining and exploration projects are shown in Figure 3-9-1.

ACCESS AND PHY SIOGRAPIHY Large lakes at elevations ranging from 656 to 844 re t res provide boat access to about 30 per cent of the map area. These lakes are most easily reached by floatplane or hslicopter, both stationed in Atlin some 40 kilometres to the east. During high water (earl) July through to late Septenber) Tagish Lake can also he reached from Atlin by powerbolt via the Atlin River....

We report on the second and final year of geological mapping in the Nakina area, conducted under the Atlin Targeted Geoscience Initiative (TGI). Principal aims of the TGI are to create a legacy of high quality geoscience data that will stimulate geological resource exploration, and regional economic development (see Atlin TGI Part I). Geological maps produced as part of the project portray base...
متن کاملInvestigation of pedological criterion on land degradation in quaternary rock units (case study: Rude-Shoor watershed area)
To investigate pedological criterion on land degradation in Quaternary rock units, at first, a part of the shoor watershed area was selected. After distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. In this research three indices of erodibility, salinity and permeability of soils were considere...
متن کاملDiscrimination of Quaternary iron placer deposits by integrating remote sensing band ratio, magnetometry and geology data by weighted overlay index method compared to SAM and FCC methods in 1:100000 sheet of Hamedan
Abstract Quaternary placer deposits are becoming increasingly important. Remote sensing is a very powerful tool in discriminating altered areas related to intrusion deposits, which has significantly reduced the cost and time of exploration. In this study, to identify iron-bearing alluvial zones within the 1:100000 sheet of Hamedan, satellite image processing techniques such as band ratio (BR),...

The Gaza Strip constitutes the south-western part of Palestine. The loess deposits were observed in the Middle and Gaza Governorates in Gaza Strip. This study carried out in the Wadi Gaza where Quaternary loess well crops out. Twenty three samples were collected from nine observation sites in the study area, and performed a textural, calcium carbonate and organic matter content studies. The loe...
