Geology and Mineral Deposits of the Keweenaw Peninsula and Vicinity, Michigan

The area of this data set includes the classic geology and mineral deposits of the Keweenaw Peninsula, renowned for the occurrence of great volumes of Middle Proterozoic flood basalts and the world's largest concentration of native copper. Native copper was mined there continuously from the 1840's to the 1960's. For the earlier part of that period the Keweenawan native copper district was the principal source of copper for the United States.

Quaternary Geologic Map of the Lake Superior 4° x 6° Quadrangle, United States and Canada

The Quaternary Geologic Map of the Lake Superior 4° x 6° Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past 2+ million years, the period that includes all activities of the human species. These materials are at the surface of the earth. They make up the "ground" on which we walk, the "dirt" in which we dig foundations, and the "soil" in which we grow crops. Most of our human activity is related in one way or another to these surface materials that are referred to collectively by many geologists as regolith, the mantle of...

Digital Geologic Map of the Penokean Continental Margin, Northern Michigan and Wisconsin

The data on this CD consist of geographic information system (GIS)coverages and tabular data on the geology of Early Proterozoic andArchean rocks in part of the Early Proterozoic Penokean orogeny.The map emphasizes metasedimentary and metavolcanic rocks that weredeposited along the southern margin of the Superior craton and werelater deformed during continental collision at about 1850 Ma. Thearea includes the famous iron ranges of the south shore region ofthe Lake Superior district. Base maps, both as digital rastergraphics (DRG) and digital line graphs (DLG) are also provided forthe convenience of users. The map has been compiled from manyindividual studies, mostly by USGS researchers, completed during thepast...
