Titanite CaTiSiO 5 occurs as a rare mineral in magmatic and metamorphic rocks. It is commonly found in clastic sedimentary rocks as an accessory heavy mineral - a mineral of high density. Recently, U-Pb dating of single-grains of detrital titanite has been shown to be a useful tool in sedimentary provenance studies e. Titanite U-Pb geochronologies can add important information to constrain the sediment sources of rocks and basins, and can help date precipitation of titanite. However, there are a number of complicating factors that must be taken into consideration for reliable application of titanite U-Pb dating in provenance studies.

Sep 14, Identifying and dating large impact structures is challenging, as many of the traditional shock indicator phases can be modified by post-impact processes. Refractory accessory phases, such as zircon, while faithful recorders of shock wave passage, commonly respond with partial U-Pb age resetting during impact events. Titanite is an accessory phase with lower Pb closure temperature than Cited by: 7. In situ U-Pb dating of titanite by LA-ICPMS Titanite, a common U-bearing accessory mineral with unique mineralogical and geochemical characteristics, can be widely used as a precise and robust geochronometer [1,5,7]. Recently, U-Pb dating of titanite has been well developed due. May 06, 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 nm ArF laser-ablation system and Agilent a Q-ICP-MS.

Titanite (CaTiSiO5) occurs as a rare mineral in magmatic and metamorphic rocks. It is commonly found in clastic sedimentary rocks as an accessory heavy mineral - a mineral of high density. Recently, U-Pb dating of single-grains of detrital titanite has been shown to be a useful tool in sedimentary provenance studies (e.g. McAteer et al. ; Thomsen et al. ).Author: Rikke Weibel, Tonny Bernt Thomsen. High-precision LA-ICP-MS titanite dating yielded a U-Pb age of Ma, which represents the main-stage mineralization age at Huayangchuan, and is coeval with the local carbonatite dyke intrusion.
