THE ORIGIN OF THE IRON INDUSTRY IN MARYLAND

THE ORIGIN OF THE IRON INDUSTRY IN MARYLAND . Captain John Smith is generally credited with the discovery of iron ore in Maryland. There is no evidence that the Native American population ever smelted ore, although they did use it as a pigment. On a voyage in 1608, sailing up what is now called the Patapsco River, Smith noted the presence of ...

Searching for the volcanic origins of iron ore

The origin of these so-called "Kiruna-type" deposits is controversial, but a recent laboratory study, published in Nature Communications, suggests that some of these iron ore deposits could have formed from magma through the separation of immiscible liquids — some containing iron and some not — as the molten rock cooled.
