Alaska is known as the last
US
frontier, this
Alaska Wall Map shows the vast land rich in minerals. The most difficult part is knowing what
areas are important to mine and what areas shouldn't be mined. Here’s
where mapping plays a key role. State geologists are mapping the potential of
geographical areas from the land and air.
Why is Alaska
so geologically important?
Part of that involves being located on the edge of the
Pacific crustal plate. That also means multiple volcanoes and unpredictable
weather. According to geological surveys, 40 million acres of state land possess
high potential for mineral deposits. Only an eighth of this land has been
mapped.
Top resources from Alaska
include gold and oil, and they account for a large amount of Alaska’s wealth. Alaska also produces zinc, silver, copper,
platinum as well as sand and gravel.
But state geologists are interested in rarer minerals. The
strategy is to map areas with minerals strategic for military technology and/or
that we import from other countries. This list includes: platinum group
antimony, barite, chromite, cobalt, fluorite, gallium, graphite, indium,
platinum group elements, rare earth elements, rhenium, tantalum, titanium,
tungsten, yttrium and niobium.
Producing these minerals would make the United States
less reliant on importing them from other countries, saving money on
technological advances. But mining takes a toll on any environmental system. By
knowing exactly where the highest concentrations of minerals are located, environmental
impact could be lessened.
Is it worth mining rare minerals and harming Alaska’s ecosystems for
the economic independence?
