Elements, 2013
High-precision geochronology is integral to testing hypotheses regarding the correlation, causes, and rates of events and processes in Earth history. Recent studies have sought to reconcile very precise, but apparently conflicting, ages for the same geological samples and events using different chronometers.

Antiquity, 1928
In the American journal Science for 1920 mention was made of my plan for investigating certain laminated clays in North America. During a previous visit to that country in 1891 I had noticed, in several places, laminated clays, similar to late glacial melting sediments in Sweden ; these I had found, by long continued investigations, to represent the ...

In order to determine the age of tufa deposits, about 500 samples of tufa from active barriers and old deposits from the entire area of the National Park were collected by collaborators of the Ruđer Bošković Institute. Outcrops of old tufa deposits found at three locations in the Park area were dated by 230Th/234U dating method (Srdoč et al., 1994 ...
