2018-1-25  Igneous dikes and sills are extremely common styles of intrusion. They originate at depth and rise up through the crust and strata. They can be huge (kilometers thick) and run for hundreds of kilometers like the chromite and PGM-rich Great Dike of Zimbabwe, or the Whin Sill in Northumberland. They can also be tiny and measured in centimeters.

2020-8-18  The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. These minerals deposited on the sea floor in great abundance, forming what are now known as the "banded iron formations
