In this paper we present a time-stratigraphic scheme and geologic time scale for the protoplanet Vesta, based on global geologic mapping and other analyses of NASA Dawn spacecraft data, complemented by insights gained from laboratory studies of howardite–eucrite–diogenite (HED) meteorites and geophysical modeling. On the basis of prominent impact structures and their associated deposits, we pro...

[1] A rock magnetic cyclostratigraphy, based on anhysteretic remanent magnetization (ARM) intensity variations, was developed for the Eocene Arguis Formation in the Spanish Pyrenees. The Arguis Formation was sampled for ARM cyclostratigraphy, rock magnetic, and paleomagnetic analyses. Rock magnetic measurements indicate that the dominant magnetic mineral controlling the ARM cyclostratigraphy is...

This issue of Palaeogeography Palaeoclimatology Palaeoecology is devoted to papers on the Permian– Triassic boundary crisis and Early Triassic biotic recovery. It is an outgrowth of the Symposium on Early Triassic Chronostratigraphy and Biotic Recovery that was held in Chaohu, China, on May 21st–23rd, 2005 under the auspices of IGCP Project 467 and attended by about 200 Earth scientists with a ...
