Indiana's bedrock, mostly hidden, is a grand procession through Paleozoic time raised up by two arches between two basins. Bedrock in Indiana is at or near the surface only in the central south end of the state. Elsewhere it's buried by much younger sediment carried down by the glaciers ...
The three-dimensional geologic modeling procedures used to create the Bloomington Quadrangle geologic map are designed to facilitate the production of derivative map products that will complement the geologic map and address specific planning needs. Map users will also be able to link to the project ...
The Internet is becoming the medium of choice for delivering geologic information to both technical users and the general public. The Indiana Geological Survey (IGS) is currently creating a Web-based glacial and bedrock geologic map site for Allen County in northeastern Indiana. Allen County is the...
A local outbreak of autochthonous Plasmodium vivax malaria in Laconia, Greece--a re-emerging infection in the southern borders of Europe? Malaria is considered to have been eradicated in Greece and only sporadic cases in travelers are reported. However the migration of populations from endemi... ...
What is the geological definition of a mineral? Give some examples. What is sedimentary petrology? What is the Cordilleran orogeny? How are geologic epochs and eras defined? What do topographic maps show? What is the Compendium of Paleozoic Rock-Unit Stratigraphy in Indiana?

This work was supported by a USGS EDMAP research grant. The LaSalle Anticlinorium locally influences the bedrock. The anticlinorium, which is strongly asymmetric, trends N20W, and extends from south-west Indiana to north-central Illinois. Although the western limb dips as much as 35 degrees...

Since the bedrock in east central Indiana is topographically invariant, non-inclined, and often not exposed, we have developed a new introductory GIS project that simulates structural features. It utilizes inclined, one-foot square planes that are placed upon a series of pedestals stationed in an...
Future visitors to the GNC Web site will learn much more about Indiana stratigraphy than just formal nomenclature. The Web site will guide professionals and lay persons to a greater understanding and appreciation of Indiana geology.HASENMUELLER, Nancy R...
