The use of bryophytes in monitoring heavy metal deposition is considered and comparisons are made with direct deposition measurements. REFERENCES. The ability of Sphagnum to absorb cations preferentially from dilute solutions resembling natural waters. Bryophytes associated with mineral deposits and solutions in Alaska.
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.
The range of iron concentrations was METAL ACCUMULATION BY AQUATIC BRYOPHYTES TABLE 4 RANGE OF METAL CONCENTRATIONS IN BRYOPHYTES FROM FRONGOCH, WEMYSS, GRAIGGOCH AND CWM RHEIDOL MINES (VALUES EXPRESSED AS PPM ON A DRY WEIGHT BASIS) 43 Zinc Lead Copper Iron Frongoch mine PhilonotisJontana.
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.
