Topic: Zircon and titanite U-Pb dating of the Zhangjiawa iron.

U-Pb dating confirms early Cretaceous magmatism and mineralization at Zhangjiawa. • Iron skarn mineralization of the North China craton took place during 135–125 Ma.. A causal link between the iron skarn mineralization and the destruction of the NCC.

1 Re: U-pb dating of titanite

Uranium–lead dating - Wikipedia Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised [2] from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.

In situ U-Pb dating of titanite by LA-ICPMS - Springer. Thus Goldberg (1963) developed the first principles of the 210Pb dating method, which was soon followed by a paper by Crozaz et al. (1964), who examined.

5 Re: U-pb dating of titanite

Combined oxygen-isotope and U-Pb zoning studies of. Titanite is an important U-Pb chronometer for dating geologic events, but its high-temperature applicability depends upon its retention of radiogenic lead (Pb). Experimental data predict similar rates of diffusion for lead

In situ petrographic thin section U–Pb dating of zircon. International Journal of Mass Spectrometry 253 (2006) 87–97 In situ petrographic thin section U–Pb dating of zircon, monazite, and titanite using laser ablation–MC–ICP-MS

7 Re: U-pb dating of titanite

In situ U-Pb dating of titanite by LA-ICPMS - Open Access. Titanite is an ideal mineral for U-Pb isotopic dating because of its relatively high U, Th and Pb contents. Here, we developed a technique for U-Pb dating of titanite using the 193 nm ArF laser-ablation system and Agilent 7500a Q-ICP-MS. Standards of titanite (BLR-1 and OLT-1) and zircon (91500 and.

8 Re: U-pb dating of titanite

LA-ICPMS U-Pb dating of titanite: New constraints on. Established techniques for the laser ablation ICP-MS U-Pb analysis of zircon have been developed for applications to common Pb bearing phases, including titanite and allanite. A novel common Pb correction procedure has been developed for deriving mineral ages, and has been tested using well characterised samples. This technique has been applied to samples from the mining district of Norbotten.
