The Macon Complex; An ancient accretionary complex in the southern Appalachians The Macon Complex; An ancient accretionary complex in the southern Appalachians
The Macon Complex, which extends from eastern Alabama to northern North Carolina, is a late Precambrian–Middle Cambrian accretionary complex comparable in size to the Franciscan Complex of California and Oregon. Much of the complex is tectonic, sedimentary, and metamorphic chaos, properly termed mélange, where well-rounded to angular fragments, blocks, and slabs of contrasting...

Mélanges and olistostromes in the Appalachians of the United States and mainland Canada; An assessment Mélanges and olistostromes in the Appalachians of the United States and mainland Canada; An assessment
There is no completely accepted definition of a mélange, and the papers in this volume reflect this fact. In our regional assessment, the term mélange is principally used for a technically fragmented and mixed body of rock. A different term, olistostrome, is used for a chaotic and mixed rock body that formed by sedimentary processes such as slumping or gravity sliding. The term...

Zircon geochronology of Precambrian rocks in southeastern Wyoming and northern Colorado Zircon geochronology of Precambrian rocks in southeastern Wyoming and northern Colorado
Archean gneisses and Early Proterozoic metasedimentary rocks of the Wyoming Province are separated from Proterozoic eugeoclinal metamorphic rocks by a major east-west–trending shear zone called the Cheyenne belt. U-Pb zircon ages of Archean tonalites north of the Cheyenne belt denote an intrusive event at 2,700 Ma. Detrital zircons from Proterozoic metasedimentary rocks north of the...

Transport and degradation of water-soluble creosote-derived compounds Transport and degradation of water-soluble creosote-derived compounds
Creosote is the most extensively used insecticide and industrial wood preservative today. It is estimated that there are more than 600 wood-preserving plants in the United States, and their collective use of creosote exceeds 4.5xl06 kg/yr (von Rumker et al., 1975). Creosote is a complex mixture of more than 200 major individual organic compounds with differing molecular weights...
