Eos dating

Facing the Data Tsunami of 100 terabytes plus every day capturing data to identify trends or patterns is critically useful for economy.

In return, geochronologists must address the research priorities of the disciplines they support and provide enhanced user access to data.

In one instance after another, geochronology has provided information that drastically changes our understanding of natural phenomena.

These radiometric dating techniques are based on the decay of uranium into stable lead isotopes (U-Pb dating).

The fission decay of uranium-238 causes linear damage zones in the mineral crystal lattice, called fission tracks, which are preserved once the grain cools.

The similar ages of mineral grains collected from the shelf, slope, and proximal deep-sea fan cores reveal that not much sediment mixing occurs along this margin and that all three areas received sediment from the same region during the past 1.2 million years.

The distal deep-sea fan deposits suggest that the source of the sediment changed between about 3.5 million and 10 million years ago.

The development of high-precision uranium-lead (U-Pb) zircon dating is currently revolutionizing our understanding of magmatic timescales as well as the tempo of sediment accumulation and biologic change.
