Late Miocene through Holocene Micropaleontologic collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California Late Miocene through Holocene Micropaleontologic collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California
This project has inventoried and produced a digital database of Late Miocene through Holocene micropaleontologic slides and data available in the USGS collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California. The digital database includes the location of samples, content of the samples, results of analyses, and other information in a format that can be...
Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru Diatom Samples from Ocean Drilling Program Leg 112, Holes 682A and 688E from Offshore Peru
The diatom biochronology of ODP Holes 682A and 688E provides a nearly complete offshore reference section to correspond with onshore studies of the Miocene age materials of the East Pisco Basin of Southern Peru, which is known for its excellent preservation of fossil vertebrates. From these holes a nearly complete sequence of low latitude and northeastern Pacific diatoms has been...
Microfossil Samples from the East Pisco Basin, southern Peru Microfossil Samples from the East Pisco Basin, southern Peru
The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest...
