metadata.value: The use of zircon U-Pb geochronology to study the provenance of sediment is well-established, yet there are fundamental
  biases that are hard to avoid. These biases are due, in part, to the limited range of magmatic compositions
  from which zircon will crystallise. This can manifest as the over/under representation of particular age
  populations (i.e. sediment sources) in the data. The analysis of apatite, a mineral found in a wide variety of igneous
  rocks, can help to address this bias in detrital geochronology. In this study, we combine geochemical and UPb
  LA-ICP-MS analysis of individual apatite grains to characterise the potential source rocks. This information is
  integrated with zircon U-Pb data fromthe samesamples in order to demonstrate the complementary provenance
  information that can be derived from apatite and zircon archives. The analysis of detrital apatite from sedimentary
  rocks in the Yenisey Ridge (Siberia) found two main U-Pb age populations. An apatite U-Pb population at
  880–720 Ma corresponds to Neoproterozoic magmatism in the Yenisey Ridge, and a second at ~1800 Ma to
  magmatism related to the assembly of the Siberian Craton. Abundant Neoproterozoic apatites, many of which
  have chemistries indicative of crystallising from a mafic magma, are considerably more common than the relatively
  rare zircons of the same age. The ability of apatite analysis to detect mafic magmatic sources is one of
  the strengths of this approach that makes it particularly useful when used in combination with zircon U-Pb geochronology.
  This study shows that multi-method analysis of detrital apatite has the potential to be an important
  tool in conjunction with detrital zircon analysis in future efforts to understand the provenance of sedimentary
  rocks.
