This method has been used in the search for and study of direct shipping ores, but it has proven to be especially useful in the study of large tonnage, wide, near surface "taconite type" ore bodies that have been the primary concern of the Fe ore industry during the past decade. The gravity method was first applied to Fe ore exploration as a tool for detecting nonmagnetic ores, but advantages ...
The Michigan iron ores are found in very old PreCambrian rocks of Huronian SubGroup ( to billion years old). The iron formations are associated with slates and quartzites that have been metamorphosed and folded. An unknown quantity of iron formation has been removed by glacial activity leaving the formations exposed at the surface in many areas. Jasper Knob near Ishpeming provides a ...
