Climate during the Early Cretaceous in tropical South America has often been reconstructed as arid. However, some areas seem to have been humid. We reconstructed the floristic composition of two tropical stratigraphic successions in Peru using quantitative palynology (rarefied species richness and abundance), and used the abundance of aridity vs. humidity indicator species to infer the predominant climate conditions of this region. The Berriasian to Hauterivian La Merced succession was dominated by fern spores and was predominantly humid. The Albian Aguas Frias succession yielded rich palynofloras, with 127 species, and also indicates predominantly humid conditions. These results support the hypothesis that the...

The Alaska Geologic Materials Center (GMC) in Eagle River holds non-proprietary rock core and cuttings that represent over 13 million feet of exploration and production drilling in Alaska. Additionally, the collection holds more than 252,000 linear feet of diamond-drilled hard-rock mineral core, representing more than 1,800 exploratory boreholes; 76,000 linear feet of oil and gas core and rock samples from more than 1,650 exploratory or production wells; samples for geotechnical boreholes; and numerous surface rock and sediment samples. The collection also includes extensive geochemical data and processed material derived from this rock. This publication represents the GMC inventory in accessible, intuitive digital...
