We’ve seen that evaluating an idea in science is not always a matter of one key experiment and a definitive result. Scientists often consider multiple ideas at once and test those ideas in many different ways. This process generates multiple lines of evidence relevant to each idea. For example, two competing ideas about coral atoll formation (island subsidence vs. formation on debris-topped und...

Reconnaissance geologic mapping of south-central Oregon is being done by the U. S. Geological Survey, in cooperation with the State of Oregon Department of Geology and Mineral Industries, as part of a larger program to prepare a geologic map of the eastern half of the state. Current work in south-central Oregon is limited geographically to the eastern half

mapping of a I5 square kilometre area around Jock Creek and detailed (1:lOOO) mapping of the mineralized area were carried out in 1988 and 1989. Marsden and Moore (1989) give an account of the geology outlined by mapping during the 1988 field season. This report presents some additions and revisions to that stratigraphy, integrates field observations with petrographic work and literature rese...
