Quantitative biostratigraphy-achieving finer resolution in global correlation

Article Abstract:

The fossil record preserves a wide range of events, including the originations and extinctions of species, the occurrence of distinctive faunal assemblages, magnetic field reversals, and volcanic ash falls that might be used to build timescales and correlate strata from place to place. Quantitative methods have shown to improve resolution up to tenfold over traditional methods that discard many potentially useful events.

Influence of the Mendocino triple junction on the tectonics of coastal California

Article Abstract:

The migration of the Mendocino triple junction through central and northern California since 1980shas led to a profound change in plate interactions along coastal California. The coupling leads to ephemeral thickening of the overlying North America crust, associated uplift and subsequent subsidence, and a distinctive sequence of fault development and volcanism.

Early crustal evolution of Mars

Article Abstract:

The bulk ~50-km thick Martian crust is formed at ~4.5 Gyr B.P from a magma ocean and this crust is a basaltic andesite or andesite and is enriched in incompatible and heat producing elements. The early impacts modify the hemisphere contrast in crustal thickness, which is possibly caused by long-wavelength mantle convention.
