Supplementary gravity data on an anomaly delineated from an aeromagnetic survey of northeastern Iowa is presented in this report. The gravity survey included observation stations located at section corners from central to western Fayette County. Analysis of the simple Bouguer map, residual gravity maps, and gravity profiles suggests that the observed gravity anomalies probably derive. 3 LEGEND FOR BEDROCK GEOLOGIC MAP OF IOWA Note: Given thicknesses and lithologic descriptions of individual map units apply only to areas of bedrock outcrop shown on the map unless otherwise indicated.

Continental crust. Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the crust of continents, often in the form of granite. Basement rock is contrasted to overlying sedimentary rocks which are laid down on top of the basement rocks after the continent was formed, such as sandstone and sedimentary rocks which may be deposited on.

They are thickest (+ feet) in southwestern Iowa and thin toward the north and northeast. They are underlain by igneous and metamorphic rocks of the basement complex. The Annual Report series was established in to publish both administrative reports and results of geological investigations.
Reports in the series include information on the geology of Iowa's counties, summary assessments of Iowa's mineral resources (coal, gypsum, sand and gravel, etc.) and summary reports on Iowa's water resources. has already opened up a new world of opportunities for everyone involved in the business of buying or selling of all types of data.

This website is dedicated to the amateur rockhound who is interested in finding rock specimens for their collection.
It includes information such as collecting locations that I've visited or that I've researched, and also information from other rockhounds. This page allows for the entry of Rock collecting locations that have been found by users on the internet or by reference sources. The migmatite gneiss complex is the oldest basement rock, and is believed to be of sedimentary origin but was later profoundly altered into metamorphic and granite conditions.
The older metasediments were also among the earliest rocks to form on the Nigerian Basement Complex. Ray Anderson from the Cedar Valley Rocks and Minerals Society gives a brief overview of local geology and cool rocks to be found in Iowa.

The intrusion comprises a lower ultramafic part and an upper gabbroic part. The individual cumulate layers are thickest in the central part of the intrusion and become thinner toward the ends of the present surface section (FigureFigure ).In the center of the intrusion, the approximate thickness of the ultramafic part is m, and the thickness of the mafic part is m.
The object captured in the images displayed above is a foot-high, ton rock which stands alongside Highway 25 in Iowa, about a mile south of the town of Greenfield exit from Interstate Large-amplitude gravity and magnetic highs over northeast Iowa are interpreted to reflect a buried intrusive complex composed of mafic–ultramafic rocks, the northeast Iowa intrusive complex (NEIIC), intruding Yavapai province (– Ga) rocks.
The age of the complex is unproven, although it has been considered to be Keweenawan (∼ Ga). The geology of the Precambrian to Lower Palaeozoic rocks of northern Nigeria --a review / Patricia McCurry --Review of the basement geology of south-western Nigeria / M.A.
