Lichenometry dating of coseismic changes to a New Zealand landslide complex
earthquakes lichens paleoseismology
2015/9/16
Lichenometry is a surface-exposure-dating procedure that complements traditional trench-and-date stratigraphic studies of earthquakes. Lichens on the surficial blocks of a slump in the Seaward Kaikour...
Paleomagnetic dating of non-sulfide Zn-Pb ores in SW Sardinia (Italy): a first attempt
paleomagnetism non-sulfideores calamine Sardinia
2015/9/10
A first paleomagnetic investigation aimed at constraining the age of the non-sulfide Zn-Pb ore deposits in the
Iglesiente district (SW Sardinia, Italy) was carried out. In these ores, the oxidation o...
Paleomagnetic dating of tectonically influenced Plio-Quaternary fan-system deposits from the Apennines (Italy)
Quaternary breccias Central Italy Paleomagnetism
2015/8/14
The Roveto Valley is a narrow, elongated, NW-trending depression filled with continental Plio-Quaternary deposits that outcrop at different topographic elevations. A morpho-lithostratigraphic successi...
A re-evaluation of the Italian historical geomagnetic catalogue: implications for paleomagnetic dating at active Italian volcanoes
the Italian historical geomagnetic catalogue paleomagnetic
2014/12/31
Paleomagnetism is proving to represent one of the
most powerful dating tools of volcanics emplaced in Italy
during the last few centuries/millennia. This method requires
that valuable proxies of th...
Ion microprobe Al–Mg dating of single plagioclase grains in an Efremovka chondrule
Al–Mg dating chondrule ion microprobe Efremovka
2017/4/11
We report here technical details of 26Al–26Mg dating of single plagioclase grains located in a chondrule of the Efremovka
CV3 chondrite using a high spatial resolution secondary ion mass spectrometer...
In situ rutile U–Pb dating by laser ablation-MC-ICPMS
laser ablation MC-ICPMS rutile U–Pb dating in situ
2017/4/11
A method for in situ rutile U–Pb dating was developed using a multiple-collector (MC) ICPMS coupled to an excimer
laser-ablation system. Compared with single collector Quadruple ICPMS used by previou...
Deciphering boulder mobility and erosion from cosmogenic nuclide exposure dating
Deciphering boulder mobility erosion from cosmogenic nuclide exposure dating
2014/4/8
Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion...
Mixing effects in zircon U–Pb ion microprobe dating: An example from a quartzofeldspathic dyke in the Yeongdeok pluton, southeastern Korea
SHRIMP zircon dating mixing dyke
2017/4/11
A swarm of quartzofeldspathic dykes extensively intruded the Permian–Triassic Yeongdeok pluton and xenoliths therein
in southeastern Korea. Zircons from the dyke intruding a diorite xenolith yield se...
Optimization of ablation protocol for 200 nm UV femtosecond laser in precise U–Pb age dating coupled to multi-collector ICP mass spectrometry
laser ablation UV-femtosecond zircon U–Pb dating
2017/4/12
The ablation protocols for 200 nm ultra violet-femtosecond laser ablation (200FsLA)—inductively coupled plasma
mass spectrometry (ICPMS) have been examined using a quadrupole ICPMS and applied to zir...
Location of the River Euphrates in the Late Miocene; dating of terrace gravel at Shireen, Syria
Location of the River Euphrates the Late Miocene dating of terrace gravel at Shireen Syria
2010/9/28
We report gravel of the River Euphrates, capped by basalt that is Ar-Ar dated to ~9 Ma, at Shireen in northern Syria. This gravel, preserved by the erosion-resistant basalt, allows us for the first ti...
