Optimizationof the Working Parameters of LA-ICP-MS and Its Application to Zircon U-Pb Dating

Yankuang ceshi, 2017
Laser Ablation (LA) combined with Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) avoids cumbersome analysis of solution and time-consuming pre process, thus reducing possible pollution during sample preparation.

SHRIMP U-Pb zircon dating on Nyainqentanglha granite in central Lhasa block

Chinese Science Bulletin, 2004
The Nyainqentanglha granite, a batholith with an area of 1500 km2 in the central Lhasa block, comprises mainly medium-fine-grained biotite monzonitic granite and medium-coarse-grained biotite monzonitic granite. Their contact relationship suggests that the medium-fine-grained biotite monzonitic granite was crystallized earlier than the medium-coarse ...

Turning Trash Into Treasure: Extracting Meaning From Discordant Data via a Dedicated Application

Geochemistry, Geophysics, Geosystems
Zircon U–Pb geochronology is a vital tool for dating geological events, but interpreting discordant zircon ages—often the result of Pb loss due to fluid‐rock interactions—remains challenging.

Is there a Grenvillian basement in the Guerrero-Morelos Platform of Mexico?

Geologica Acta, 2007
In the Guerrero-Morelos platform (Guerrero State, Mexico) the adakitic rocks of Early Tertiary age contain abundant hornblende-rich tonalite xenoliths. Zircon crystals have been concentrated from both adakites and xenoliths, and dated using in-situ U-Pb ...

From ID-TIMS U-Pb dating of single monazite grain to APT-nanogeochronology: application to the UHT granulites of Andriamena (North-Central Madagascar)

BSGF - Earth Sciences Bulletin
The causes of U-Pb isotopic discordance documented by Paquette et al. (2004) in monazite grains from the ultra-high temperature (UHT) granulite of the Andriamena unit of Madagascar are re-evaluated in the light of nanoscale crystal-chemical ...

Mineralogy of the inclusions and age of zircon from granite basement of Verkhnerechensk area (Yamal peninsula)

Литосфера, 2017
The study of minerals-prisoners in accessory zircons is gradually evolving into an important geological-petrological task. Such a study can show not only the earliest mineral rock association, but also evaluate the “sealed” mineral paragenesis of zircon,

Holocene Provenance Identification and Climate Control of Indus Basin By Using Radiogenic Techniques and Clay Mineralogy [PDF]

International Journal of Economic and Environment Geology, 2011
Two commonly used isotopic methods (Zircon U-Pb dating and K-feldspar Pb dating) were employed for the Holocene provenance identification within the Indus basin.
