Allanite U–Th–Pb geochronology by ion microprobe

, 2020
Allanite, an epidote group mineral, occurs as a common accessory mineral in igneous, metamorphic rocks and hydrothermal deposits. It contains radioactive elements Th and U, making it a valuable U–Th–Pb geochronometer for various geological processes. Due

Geochronology

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 ...

Geochronology

2013
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 ...
