The Cripple Creek epithermal deposit is a historic gold camp located at the southern end of the Colorado Front Range in central Colorado. Mineralization in the Oligocene-aged alkaline volcanic center is characterized by ...

The Zoeppritz equations used in a typical reflection amplitude versus source-receiver offset (AVO) study to calculate the reflection and transmission coefficients do not directly consider the fluids filling the pore space ...

The recent expansion of Juniperus ashei (Ashe juniper) on the Edwards Plateau of Central Texas has prompted studies on the impact the juniper expansion has had on the hydrologic regime of the region. This study addresses ...

The traditional roles of stable isotopes in paleontology are as indicators of diet or climate. An emerging field of paleontology and geochemistry is to use isotopes in order to make inferences about extinct and fossil ...
