Geology experts put time in its place

University of Leicester researcher publishes article in American geology magazine about the terms used to describe the age of rocks.

In the March issue of GSA Today, the monthly news and science magazine for the Geological Society of America, a team of researchers led by Dr Jan Zalasiewicz from the Department of Geology at the University of Leicester propose a realignment of the terms "geochronology" and "chronostratigraphy", terms which refer to the age of rocks.

The system seeks to both bring the terms broadly in line with current use and to resolve the debate of whether units of the Geological Time Scale should have a single (time) or dual (time and time-rock) hierarchy.

In the system, both hierarchies would remain available for use -- geochronologic units continuing as the time units while chronostratigraphic units continue as the time-rock units.
