Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson Oct 2001

Island Arcs, Accretionary Terranes And Midcontinent Structure New Understandings Of The Geologic Architecture Of The U.S. Midcontinent, Marvin P. Carlson

Conservation and Survey Division

A data base collected over the last 100 years, containing both surface and subsurface information, has allowed us to begin to understand the physical framework of Nebraska. We have learned that even in the stable Midcontinent region of North America, there has been an active geologic history. This framework has been deciphered by our programs of surface geologic mapping and by the study of rock samples from both water wells and those deeper test wells for oil and gas. Determining the major structural features across the state (figure 1) has allowed us to better understand both the occurrences of its …

The limestone region of Puerto Rico covers about 27.5 percent of the island's surface and is subdivided into the northern, southern, and dispersed limestone areas. All limestone areas have karst features. The karst belt is that part of the northern limestone with the most spectacular surficial karst landforms. It covers 142,544 ha or 65 percent of the northern limestone. The karst belt is the focus of this publication, although reference is made to all limestone regions. The northern limestone contains Puerto Rico's most extensive freshwater aquifer, largest continuous expanse of mature forest, and largest coastal wetland, estuary, and underground cave …

Late Maritime Woodland (Ceramic) And Paleoindian End Scrapers: Stone Tool Technology, Pamela J. Dickinson Jan 2001

Late Maritime Woodland (Ceramic) And Paleoindian End Scrapers: Stone Tool Technology, Pamela J. Dickinson

Electronic Theses and Dissertations

Archaeologists tend to view lithic assemblages from a predominately morphological perspective, stressing the importance of the fluted point as the defining characteristic of the Paleoindian culture period (ca. 10,000 years B.P.). In applying such a characteristic, Paleoindian sites have been identified throughout the Northeast. However, there are no identified Paleoindian sites in New Brunswick. It is possible that some sites are largely ignored or thought to lack a Paleoindian component if a fluted point is absent. If such sites are being overlooked, then the database may under represent the Paleoindian culture period. Spurred end scrapers commonly occur in known Paleoindian …
