Farley, R. Geology ; 43 12 : — Newly developed techniques were used to characterize the age, origin, and temperature history of coarse hematite contained in high-grade iron ore. These data reveal that while two of the specimens grew at ca. Fe mobilization and recrystallization in open cavities at 3—5 km subsurface has occurred episodically or possibly continuously over hundreds of millions of years despite a quiescent tectonic setting throughout this interval. While the analyzed specimens are distinct from typical Fe ore, their ages along with structural relationships constrain the onset of iron enrichment to between and Ma. Shibboleth Sign In.

But, those are all bigger metro areas. It’s probably on par with most of the metro areas of the same size, but punches above it’s weight compared to other mid-western cities and lags behind similar sized cities on the coast like San Diego and Portland.

A version also ran as a radio essay on Sorry about that. Hey, whatever gets you through the long, cold night. I kid of course. But at least we can all be glad that expressing our undying love for another will not lead to a brutal beheading. With three little ones at home, we find it best to set aside our own romantic dates rather than try to secure a babysitter on a Thursday for a meal that will cost us twice as much in a restaurant clouded with excess perfume.
But it sure is interesting to see how the holiday affects the mass media.

Public access, however, may be restricted when school trust lands are under a contract to generate revenue for K public education. Common examples that limit access include mineral exploration and active mining, timber sales, grazing contracts, communication towers, and aggregate development. They may also necessitate temporary or permanent closure of certain lands to the public.

In , a group of like-minded individuals got together on the east end of the Mesabi Range in northeastern Minnesota and founded a new organization. Their goal was to preserve the history of the area. There was a deep concern among officials and citizens alike that buildings, documents, photographs, and other items of historic value were being lost to the elements, carelessness, and even just the complacency of the people of the region.
This new organization took the name; East Range Historical Society. It was the first historical society on the Mesabi Range. Members of the Society met first in Aurora, then briefly in Biwabik.
According to the Friends of the Northland FireWire, several departments responded to the fire around a.m. at the Moose Event Center on Howard.
Duluth, Minn. It produces high-quality iron ore concentrate from previously abandoned iron ore waste stockpiles and tailings basins using a patented magnetic separation process. Minnesota Power provides service to two other Magnetation plants on Minnesota’s Mesabi Iron Range as well as a rail loading facility. The largest of these, Plant 4 will require up to 20 megawatts MW of electric power and will produce 2 million metric tonnes of iron concentrates annually following completion of construction later this year.
Magnetation has said it expects Plant 4 to be operating early in the first quarter of Minnesota Power and Magnetation entered into an electric service agreement for Plant 4’s 20 MW load through at least that was approved by the Minnesota Public Utilities Commission in May Magnetation’s Plant 4 required the Duluth-based energy company to permit and build the Canisteo substation and route and construct kilovolt transmission lines totaling about ten miles in length.

This guide is compiled by staff at the Minnesota Legislative Reference Library on a topic of interest to state legislators. It introduces the topic and points to sources for further research. It is not intended to be exhaustive. While the focus of mining to date has been iron deposits known as “ferrous mining” , the ores also contain a variety of precious metals including copper and nickel. Over the next two decades, exploratory studies and drilling identified large deposits of potentially minable low-grade ore deposits.
In the federal government granted the International Nickel Company, Inc. These leases predate many of the environmental protection acts that would soon follow in the late s and throughout the s. In and , the legislature made appropriations to the University of Minnesota for “ore and geological research,” which included “experiments The goal was to study the possible region-wide environmental, social, and economic effects of copper-nickel mining and to collect baseline data from which to measure the effects of mining development.
After the study’s publication, the public was both excited by the economic possibilities of a new mining industry in northern Minnesota and concerned by its possible environmental effects.

In this article, an overview is presented of the status of the radiocarbon dating of iron-based materials. Recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements, and the potential use of rust as a viable source of material for radiocarbon dating. Additionally, a summary is presented of all 63 previously published results for iron-based materials and 29 new results that have not been published previously.
These materials range from low-carbon wrought irons to medium to very high-carbon steels and cast irons.
The iron dating project Aikarauta has been launched in Finland. The temperature inside a typical furnace ranges from °C (top) to > °C (at the air inlet.

For decades, Jim Klobuchar was a daily columnist for the Minneapolis Star Tribune; part sportswriter, raconteur-adventurer, voice for the voiceless, and needler of the ruling class.
That got her teased at school. And then, in , there was the front-page article Jim had to write about his own arrest for drunken driving. Amy had plenty of material to work with. There was the time they drove to a bar after a Vikings game — he got tanked while she drank a 7-Up. The time he swerved his car into a ditch with her in the passenger seat. All the times he pretended the bottle he kept in his trunk was mouthwash, and the times Amy and her younger sister, Beth, sat in the room above the garage, staring out the window and waiting for him to come home.
