COMMERCIAL-GRADE MORDENITE OF THE HORN MOUNTAINS, SOUTH-CENTRAL ALASKA By D.B. Hawkinsl ABSTRACT The Horn Mountains, in south-central Alaska, have zeolitized tuff beds 14 kilometers long and at least 30 meters thick and that consist of 50 percent mor- denite.

This mordenite tuff is or commercial grade and. Additional Physical Format: Online version: Hawkins, D. (Daniel Ballou), Commercial-grade mordenite deposits of the Horn Mountains, South-Central Alaska. Additional Physical Format: Online version: Hawkins, D.

(Daniel Ballou), Mordenite deposits and zeolite zonation in the Horn Mountains area, south-central Alaska. Horn Mountains are probably the largest known high-grade mordenite deposit in North America. Location: On southeast flank of Horn Mountain, 2, ft north of headwaters of Wood Creek.

The occurrence extends along the flank, northeast of the point given. Accurate within 2, ft. Locality 71 of MacKevett and Holloway (). The chemical compositions for the two samples are listed in Table 1. ZEOLITE&Vo12, April The deposit locality for the natural sample is the Horn Mountains Area, South-Central Alaska.

The Greens Creek mine resumed production in latefollowing renewed exploration and development of the volcanogenic massive sulfide deposit. The Fort Knox gold mine, near Fairbanks, is under construction and is scheduled to yield ore by late In southwest Alaska exploration success has yielded a significant gold resource at Donlin Creek.

The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean.

Alaska was largely ice free during the Pleistocene. This article comprises three sortable tables of major mountain peaks of the U.S.

State of Alaska. The summit of a mountain or hill may be measured in three principal ways. The topographic elevation of a summit measures the height of the summit above a geodetic sea level. The first table below ranks the highest major summits of Alaska by elevation.; The topographic prominence of a summit.

This high point in the road gives you an excellent view across the valley. Three ditch lines from earlier mining activities are apparent on the far side of the valley, especially where they cross the exposed rock face of Cape Horn.

These mountains lie in the central Alaska Range, roughly miles east of Denali (Mt. McKinley). To the east of the Parks Highway and north of the Denali Highway (the gravel highway that connects Cantwell to Paxson), they are relatively inaccessible and seldom climbed.

Located on Prince of Wales Island in Southeast Alaska, Bokan Mountain hosts a deposit with million metric tons of indicated resource averaging percent ( million pounds) total rare earth oxides. While not particularly high-grade, the mix of rare earths found at Bokan is what makes this Southeast Alaska deposit attractive.

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.

The property is currently ranked 15th in North America for total tonnage of contained rare earth metal oxides. However, unlike other U.S. deposits, Bokan Mountain is enriched.

The Wrangells are between the Chugach and St. Elias Mountains on the south and the Alaska Range's Mentasta Mountains on the north. Several active volcanoes are visible to one traveling to Glenallen.

Wrangell, Alaska's largest active volcano, is 4, feet high. Visit the Wrangells any time of year for adventure. The BLM Alaska minerals program has responsibilities and adjudicative duties associated with Federal mining claims, mineral surveys and patents, validation of title evidence, review of mineral validity reports, service of Federal minerals contest actions, guidance for surface use management and use and occupancy under the mining laws.

The Alaska Range is a relatively narrow, mile-long ( km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end to the White River in Canada's Yukon Territory in the southeast.

The highest mountain in North America, Denali, is in the Alaska is part of the American Cordillera.Alaska's coal fields are closed by political controversy. Development of Alaska's coal fields, among the largest in the world, became entangled in national politics. The Natives, Russians, and early Americans in Alaska had used coal for their local needs.

Many of Alaska's coal deposits had been discovered by .Alaska Guide Co. is based in Valdez, Alaska and seeks to educate people on Alaska through adventure tours and online informational resources. Recent Updates Visiting Valdez - Most everything you want to know -
