“…Population 4 (Figure 3, red) displayed moderately to strongly depleted LREEs with significant negative Eu anomalies (with the exception Population 1 (Figure 3, deep yellow) was characterized by moderately enriched LREEs with no or only slightly negative or positive Eu anomalies. The REE patterns in this population were similar to those of apatite from relatively unfractionated, more mafic sources (e.g., syenite, lherzolite, and carbonatites) [20][21][22]74]. Population 2 (Figure 3, black) also yielded moderately enriched LREE profiles but showed significant negative Eu anomalies.…”

“…Therefore, the trace element compositions and element ratios of apatite can be used as important indicators to distinguish the host rock types. Provenance discrimination studies based on apatite geochemistry have demonstrated many methods for the classification of detrital apatite grains [20,65,66], which have been successfully adopted and improved in recent research [8,[21][22][23]. In this study, various strategies from the literature were combined to understand the geochemical information recorded in the detrital apatites from the SOT.…”

“…The Th vs. U binary plot that was first proposed by Reference [66] has also been successfully applied to discriminating the provenance of detrital apatite [8,[21][22][23]. The depletion in Th relative to U (Th < U) in apatite is generally caused by the growth of monazite and epidote, which preferentially concentrate Th before the crystallization of apatite.…”

Detrital apatite is a promising accessory mineral for reliable fingerprinting of the protolith composition of detrital sediment. Here, we present the geochemical compositions of detrital apatites from four sections of a high-resolution (~140 cm/kyr) sedimentary archive from the southern Okinawa Trough (SOT) for constraining sediment source rock types and establishing changes in provenance. A series of diagrams based on the geochemical data show that apatites in Section 1 derived mainly from mafic/intermediate rocks, while apatites in the three younger sections largely originated from mafic/intermediate rocks and acid rocks. Further, the four sections included a few contributions of apatites from alkaline rocks and metamorphic rocks. Through a comprehensive analysis of controlling factors and regional stratigraphy in the study area, we concluded that sediments in the SOT are the weathering/erosion products of sedimentary and meta-sedimentary rocks in the western and northeastern Taiwan Island, with ultimate sources containing a wide variety of rock types. The sediment from rivers in eastern Taiwan did not significantly contribute to deposition in the SOT. Apatites in Sections 2–4 showed strong geochemical similarity but differed from those in Section 1, indicating that the types of weathered/eroded sedimentary rocks in the weathering profile of river drainage basins of Taiwan Island changed in Section 2 (2010–1940 cal. yr BP) and have remained stable since then.

“…The major element geochemistry of sediments is frequently used in many studies to infer their provenance, because they tend to reflect the source rock composition (Al-Juboury and Al-Hadidy, 2009;Shadan and Hosseini-Barzi, 2013;Jafarzadeh et al, 2014). Similarly, the trace elements concentrated in mafic (Sc, Cr and Co) and in silicic (La, Th and REE) sediments, the REE patterns and the size of the Eu anomaly are considered as important tools to characterize the source rock composition (e.g.…”

“…Algunas ventajas y desventajas entre las metodologías basadas en LA-ICP-MS e ID-TIMS fueron también observadas y señaladas. Los resultados de este estudio INTRODUCTION Apatite, the most common phosphate mineral with typical natural occurrence as Ca 5 (PO 4 ) 3 [F,Cl,OH], has attracted great interest as a low-and medium-temperature thermochronometer (fission-track analysis, U(Th)/He and U-Pb dating; e.g., Wolf et al, 1996;Ehlers and Farley, 2003;Hasebe et al, 2004;Donelick et al, 2005;Solé and Pi, 2005;Chew and Donelick, 2012;Abdullin et al, 2014;Enkelmann et al, 2014;Spikings et al, 2015); as a chemical indicator of petrogenetic or metallogenetic processes, as well as a novel geochemical tool in sedimentary provenance studies (Belousova et al, 2002;Morton and Yaxley, 2007;Jafarzadeh et al, 2014;Abdullin et al, 2016a and2016b;Bruand et al, 2016); or even as an isotopic tracer (e.g., Sr isotopes, assuming that apatite does not incorporate any significant amount of initial Rb; Bizzarro et al, 2003); or as a proxy of the redox state of silicic host magmas as well (Miles et al, 2014).…”

Apatite is the most common phosphate mineral in the Earth's crust and can be found in practically all magmatic and metamorphic rocks, as well as in ancient and recent sediments and in certain ore deposits. Its effective closure temperature of 450-550 °C for the U-Pb system makes apatite an important natural medium-temperature thermochronometer that can be dated by both laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and isotope dilution thermal ionization mass spectrometry (ID-TIMS) techniques. Due to its low U content, coupled with high Pb contents incorporated during crystallization (also called common lead), apatite U-Pb dating is analytically challenging, and requires robust analytical protocols to achieve reliable ages. In this experimental study we obtained apatite U-Pb ages from six rock samples employing LA-ICP-MS (at Laboratorio de Estudios Isotópicos, Centro de Geociencias, UNAM), while one sample was also dated by ID-TIMS (at Laboratorio Universitario de Geoquímica Isotópica, UNAM). These samples have igneous emplacement or metamorphic ages broadly ranging from the Neoproterozoic to the Paleocene. The obtained apatite U-Pb ages agree well with other radioisotopic data (U-Pb on zircon and K-Ar or Ar-Ar on micas and hornblende) available for the same rock samples tested, or for the same geological units studied. These apatite U-Pb results, obtained for the first time at two main Mexican geochronology laboratories, are precise enough to be geologically meaningful and usually represent the cooling ages; though, in some cases they may also indicate the crystallization or the metamorphic age. Some advantages and disadvantages of LA-ICP-MS-and ID-TIMS-based methodologies were observed and outlined. Our results validate the analytical procedures used and will serve as an important trigger towards the development or improvement of medium-temperature thermochronology techniques in Mexico.
