The lead deposits of Alaska really ⇑ belong in this secondary group but they have been described together with the zinc deposits because the two metals are commonly associated in the deposits, either one or the other being the principal metal, and, therefore, to separate them would be difficult. Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore some occurrences, minerals can be extracted at a profit by mining. Mineral deposits of the Yakataga district; Chapter F: Mineral resources of Alaska, report on progress of investigations in Preliminary report on a water-power reconnaissance in south-central Alaska. “The D-2 Book”: Lands of National Interest in Alaska, pp. Beyond the fishery resources, however, are mineral resources such as gold and copper in the Bristol Bay watershed. The State of Alaska initially put general protective measures on Bristol Bay’s salmon resource in .

  Process The formation of ore minerals occurs later when tectonic processes and mountain building events channel metal-bearing fluids through the carbonate host rock. MVT deposits are closely associated with orogenic forelands – large valleys running parallel to mountain belts. The deposits formed by diagenetic recrystallization of carbonates creating low-temperature hydrothermal solution. This collection of articles summarizes environmental geochemical studies of metallic mineral deposits in Alaska, including sulfide, gold, mercury, chromium, and uranium mines and deposits. The studies report metal and acid concentrations in samples collected around such mines and deposits, and evaluate environmental effects of the deposits. An introduction explains geochemical processes, how. Alaska has major mineral deposits Alaska's mineral resources attracted many people to the north. They continue to attract people today although oil has replaced gold as the most sought-after resource. Other economically important mineral deposits in Alaska include copper, silver, mercury, platinum, tin, coal, iron ore, borax, chromite, antimony. Scientific Name Common Name Summary; Blasia pusilla: Apparently fairly common rosette forming thallose liverwort along the upper edge of the mud flats Blue Lake, and on sand bars adjacent to the main inflow stream to Blue Lake.

mineral resources of the area. The bedrock geology and aeromagnetic surveys show that mineral deposits associated with intrusive rocks are probably absent. However, the geology and geochemical anomalies do indicate the possibility of vein and strata-bound deposits of copper, lead, and zinc in the Paleozoic shale and carbonate rocks in the. Region 6: Alaska Alaska encompasses a large landmass that contains a wide variety of mineral resources. However, difficulties associated with a lack of transportation and challenging environmental conditions (extreme cold, snow, and darkness) have limited the amount of mining that can occur there. Seafloor Mineral Deposits. There are a wide variety of deep-sea mineral categories; however, our team focuses on those marine mineral categories that have the greatest resource potential. Seafloor pavements and encrusted rocks are known as ferromanganese crusts (also called cobalt-rich crusts). These crusts grow very slowly, at several.   The classic mineral in this case is limestone. Many of these solutions are acidic, and when they come into contact with limestone, the acidity is neutralized, and the mineral drop out of solution. Many very rich mineral deposits have been found where limestone comes into contact with other rock types. Gold ore from Fern Mine, Hatcher Pass.

In addition, naturally occurring surface mineralizations can produce metal concentrations in soils and vegetation that are as high, or higher, than those found around man-made sources. The searches by prospectors for such metal deposits, frequently using biogeochemical techniques, are a.

Shacklette (), for instance, reported that this species occurs in Alaska on copper minerals, pyrites, iron oxides and near zinc and lead minerals. McLean & Jones () found that S. undulata was the only bryophyte at three sampling stations on the rivers Ystwyth and Magwr, West Wales, with particularly high levels of zinc in the water.

Locations of minable elements can be determined by the deposits of the associated rocks and minerals which, when deposited in significant and refinable concentrations, are called ores.

The location of elements varies based on the minerals of which they are part and the rocks that contain those minerals. Zinc-lead-silver massivle sulfide and barite deposits hosted in dark, fine-grained clastic sedimentary rocks are economically important resources in Alaska and major producers worldwide.

Alaska contains several identified belts of such deposits, the best known and largest of which is the Noatak district in the western and central Brooks Range.

mineral resources of alaska, and (pages ) united states government printing office washington: GOLD is the top producing mineral in Alaska. Also, In the late s and early s the Alaska/Klondike Gold Rush sent hundreds of thousands of people up to Alaska in search of gold. But, did you know that Alaska also produces other minerals that are a vital part of your everyday life.

The deposit contains over 80 billion pounds (Blbs) Cu, million ounces (Moz) Au, and Blbs Mo in all resource categories. Copper and gold grades vary across diverse hydrothermal alteration assemblages with higher grades associated with sericite- and pyrophyllite-rich assemblages in an advanced argillic alteration zone.
