detrital monazite turkey

Provenance analysis of detrital monazite, zircon

In comparison, the detrital zircon is a better indicator of igneous events than detrital monazite. Synthesizing the detrital monazite, zircon and Cr‐spinel data, we concluded that the South Altyn Tagh Ocean and Qimen Tagh Ocean existed in the early Paleozoic and that the Altyn Tagh terrane and Qimen Tagh terrane experienced different Paleozoic tectonothermal histories.

Monazite geochronology - Wikipedia

Monazite geochronology is a dating technique to study geological history using the mineral monazite.It is a powerful tool in studying the complex history of metamorphic rocks particularly, as well as igneous, sedimentary and hydrothermal rocks. The dating uses the radioactive processes in monazite as a clock.

Detrital and newly formed metamorphic monazite

Based on various observations it is argued that the detrital monazite was not the direct precursor to the metamorphic monazite. The latter may rather have grown from other, more reactive REE carrier minerals, either detrital ones (e.g. detrital allanite) or such that formed during diagenesis and low

Back-scattered electron (BSE) imaging and X-ray element mapping of monazite in low-grade metasedimentary rocks from the Paleoproterozoic Stirling Range Formation, southwestern Australia, reveal the presence of distinct, high-Th cores surrounded by low-Th, inclusion-rich rims. Previous geochronology has shown that the monazite cores are older than 1.9 Ga and overlap with the ages of detrital ...

On the other hand, zircon and monazite are common detrital minerals in sedimentary rocks and sediments from modern rivers or beach placers (e.g., [22, 23]).Hf isotopes of detrital zircon and Nd isotopes of detrital monazite provide a good estimate for the average Hf and Nd isotopic composition of large continental areas that supplied the sediments [23, 24].

Abstract The oldest known rocks in Tasmania occur in the Proterozoic Rocky Cape Group, a ∼10 km thick quartzarenite-siltstone-pelite-dominated succession, previously constrained to have been deposited between 1450 Ma and 750 Ma. The Rocky Cape Group contains the enigmatic fossil Horodyskia (‘string of beads’) and has the potential to place Tasmania within supercontinent reconstructions ...

Detrital monazite ages (n = 86) include a strong Taconian mode and the Acadian mode is more substantially represented than in zircon-based studies. In addition, the elusive ca. 300 Ma old Alleghanianaged mode is repeatedly recorded by monazite.With the goal of meticulously evaluating detrital zircon as a provenance proxy, we reanalyzed zircon crystals that, based on CL imaging,
