Geologic interpretation of gravity profiles in the western Marquette district, northern Michigan
The presence of elongate troughs of Precambrian X (middle Precambrian) rocks in Precambrian W (lower Precambrian) rocks in the western Marquette district of northern Michigan has been known since the late 1800s. However, little data can be brought to bear on estimates of the depth and cross-sectional configuration of these features. For this reason, gravity models and geologic interpretations were

Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan
The Marquette Iron Range is presently ( 1973) the second largest iron mining district in the United States. Commercial iron deposits, now mostly concentrating-grade ore, are in the Negaunee Iron-formation, which is part of a thick sequence of metasedimentary rocks of Precambrian X age. These rocks are preserved in the west-trending Marquette synclinorium, and are flanked to the north and south by

Stratigraphic relationships within the Baraga Group of Precambrian age, central Upper Peninsula, Michigan
Details of the stratigraphic section in parts of northern Michigan have been known for many years, but correlation of units between geographically separated areas has been partly speculative. Mapping in the Witch Lake quadrangle has filled the gap between well-studied areas of the Marquette trough and parts of Iron and Dickinson Counties and has helped to correlate units in the Baraga Group (Preca

Geology of part of the southern complex, Marquette district, Michigan
The southern complex, south of the Marquette synclinorium in the Marquette district of Michigan, is dominantly granitic. The granitic parts of the complex have Rb-Sr ages of about 2.5 b.y. and are classed as of Precambrian W age. The rocks are divided into two major units: (1.) Bell Creek Gneiss consisting mostly of coarse megacrystic granitic rocks and lesser amounts of mafic gneiss and metasedi

A revision of stratigraphic nomenclature for middle precambrian rocks in Northern Michigan
The name Marquette Range Supergroup is proposed to supplant the term Animikie Series for middle Precambrian strata of the Northern Peninsula of Michigan and adjacent areas of Wisconsin. The Marquette Range Supergroup consists of the Chocolay, Menominee, Baraga, and Paint River Groups, as defined in previous literature. We feel that this new name to apply to Northern Peninsula rock units is appropr
