These terrane re-assignments have implications for the area¿s mineral potential. All of the major ophiolitic terranes (Angayucham, Tozitna, Innoko, Seventymile, and Goodnews terranes) in the northern and central Alaska belong to the Tethyan-type' of Moores () and were obducted onto Paleozoic and Proterozoic continental and continental margin terranes in Mesozoic time.
Thirty‐six samples from plutons of the Ruby batholith of central Alaska were collected and analyzed for 22 trace elements, and many were analyzed for the isotopic compositions of Sr, Nd, O, and Pb in order to delimit the processes that produced the diversity of granodioritic to granitic compositions, to deduce the nature of the source of magmas at about Ma, and to characterize the deep Cited by: Thirty‐six samples from plutons of the Ruby batholith of central Alaska were collected and analyzed for 22 trace elements, and many were analyzed for the isotopic compositions of Sr, Nd, O, and Pb in Cited by: OFF Ophiolitic terrane bordering the Yukon-Koyukuk basin, Alaska, by Patton, W.W., Jr., OF G Ophiolitic terranes of east-central and southwestern Alaska byCited by: 6.

Reconnaissance geologic map of the Yukon-Koyukuk basin, Alaska, which is a region characterized by isolated hilly areas and low mountain ranges, separated by broad alluviated interior and coastal lowlands. The geologic, structural, and tectonic history of the Bering Sea area since Paleozoic time is best viewed in terms of major plate-tectonic interactions.
The geotectonic style of disparate areas is apparently related to the nature of plate motion at the time of tectonic imprint. Three major. Jun 24, · The Kotzebue Basin (Alaska Geographic) [Alaska Magazine] on coffeecompanyflorida.com *FREE* shipping on qualifying offers.

The Brooks Range and adjacent Colville Basin in northern Alaska are thought to be the products of north-directed Jurassic and Early Cretaceous arc-continent collision between the south-facing (present coordinates) passive continental margin of the Arctic Alaska terrane and the Jurassic Koyukuk arc terrane of interior Alaska (e.g., Moore et al Cited by: Yukon-Koyukuk has 1, identified mines listed in The Diggings™.
The most commonly listed primary commodities in Yukon-Koyukuk mines are Gold, Silver, and coffeecompanyflorida.com the time these mines were surveyed, mines in Yukon-Koyukuk were observed to have ore mineralization in an outcrop, shallow pit, or isolated drill hole—known as an occurance mine.
1 Yukon-Koyukuk has prospect mines. Yukon - Yukon - Land: Much of the territory remains unspoiled wilderness, but the impact of people on the environment is apparent. Near the settlements reliance on wood for fuel has destroyed timber, and in remoter places forest fires have often gone uncontrolled.
In addition, surface mining has scarred the landscape near Dawson, in the west-central part of the territory, and near Whitehorse. The upper end of the Yukon River was originally known as the Lewes River until it was established that it actually was the Yukon.
North of Whitehorse, the Yukon River widens into Lake Laberge, made famous by Robert W. Service's "The Cremation of Sam McGee".Mouth: Bering Sea. It is important to note that the ophiolitic section can be derived from either the fore-arc or the back-arc, and can therefore be either the first or last stratigraphic unit emplaced in an arc terrane collision, and both scenarios have been proposed for the ophiolites emplaced in the central mountains of New Guinea.
