“…AFT analysis-derived time-temperature modeling for two sandstones sampled from the Middle(?) Jurassic Todos Santos Formation in the northern CMC area, as well as provenance studies performed in some Cenozoic units from the Sierra de Chiapas (including studies of Witt et al, 2012) suggest that in the CMC not only the Oligocene, but most of the Cenozoic was a tectonically quiescent period (approximately from Eocene to middle Miocene; Abdullin et al, 2016aAbdullin et al, , 2016b. -Amador et al, 2005;Weber et al, 2008;Estrada-Carmona et al, 2012;Torres-de León et al, 2012;Solari et al, 2013;Cisneros de León et al, 2017).…”

“…The Cenozoic tectonics of the CMC is of a particular interest because many authors (e.g., Schaaf et al, 1995;Pindell et al, 2006;Ratschbacher et al, 2009;Torres-de León et al, 2012;Witt et al, 2012) suggested an Oligocene arrival of the Chortís block to the Gulf of Tehuantepec region (i.e., as a collision of the Chortís and Maya continental blocks;), which should have been imprinted in the tectonic history of the CMC as a rapid cooling period as well as by ubiquitous stratigraphic records within Oligocene units from the inner parts of the Sierra de Chiapas (e.g., the presence of granitic conglomerates derived from the CMC rocks). Despite the controversy surrounding the Oligocene thermal history, all these AFT data detected a middle to late Miocene thermo-tectonic event that affected almost the entire territory of Chiapas (Ratschbacher et al, 2009;Witt et al, 2012;Abdullin et al, 2016a), which is essentially well-known as the Chiapanecan orogeny (e.g., Sánchez-Montes de Oca, 1979, 2006Meneses-Rocha, 2001; Padilla y Sánchez, 2007;Guzmán-Speziale, 2010). A Late Cretaceous to late Paleocene-early Eocene orogenic event was proposed previously for Chiapas by several authors (Gutiérrez-Gil, 1956;Sánchez-Montes de Oca, 1979, 2006Carfantan, 1981Carfantan, , 1985Moravec, 1983;Meneses-Rocha, 1985, 2001), a hypothesis that seems to be confirmed by recent AFT analyses performed by Abdullin et al (2016a).…”

The Chiapas Massif Complex, which represents the crystalline basement of the southern Maya block within the North American plate, records numerous thermo-tectonic and magmatic events that occurred in southern Mexico at least since the late Mesoproterozoic. The present study was performed across the northern Chiapas Massif region to reconstruct its complex thermo-tectonic history from Mesozoic to present times. Basement samples and sandstones of the San Ricardo Formation derived from the Chiapas Massif Complex source area were analyzed by in situ apatite fission-track dating. The new fission-track results obtained in this study, together with previously published data, indicate that the Chiapas Massif Complex, or rather the whole Maya terrane, have experienced a complex long-term geodynamic evolution with at least five post-Permian tectonic and magmatic events: (1) a Late Triassic cooling event, likely related to the initial breakup of Pangea; (2) Early Jurassic volcanism that can be linked to the Nazas volcanic arc; (3) a Middle Jurassic tectonic event that was triggered by continental rifting at the beginning of the opening of the Gulf of Mexico; (4) a Late Cretaceous to Paleocene orogeny that may actually represent the southernmost continuation of the Laramide sensu lato which affected central and northern Mexico; and (5) the middle–late Miocene Chiapanecan event that is tectonically controlled by the interaction of the North American, Caribbean, and Cocos plates. This interpretation could be useful towards a better understanding of the geological history of southern North America. Some recommendations on sampling and analytical strategies are also given for consideration in further thermochronological studies in Chiapas.

“…By the early 2000s, LA-ICP-MS technology had matured enough to be used for fission track dating. A proofof-concept study by Hasebe et al (2004) laid the foundations for this new approach, which has gradually gained popularity since (Hasebe et al, 2009;Chew and Donelick, 2012;Soares et al, 2014;Gleadow et al, 2015;Abdullin et al, 2016). But despite this popularity, relatively little work has been done to develop the statistical analysis of this new type of fission track data (Galbraith, 2010).…”

Despite the conceptual elegance and simplicity of the External Detector Method (EDM) for fission track dating, an increasing number of laboratories are switching to LA-ICP-MS as a means of measuring the uranium content of apatite, zircon and sphene. LA-ICP-MS based fission track (LAFT) dating offers shorter turnaround times, removes the need to handle radioactive materials and hydrofluoric acid, and facilitates double-dating with the U-Pb method. This paper aims to bring the statistical treatment of LAFT data on an equal footing with the EDM by formulating four different analytical protocols, depending on the accuracy and reproducibility of the uranium measurements. Under the 'absolute' dating approach, the spontaneous track densities and uranium concentrations are directly plugged into the fundamental fission track age equation, assuming that both of these measured quantities have been determined accurately, and that the fission decay constant and equivalent isotopic track length are known. The 'zeta calibration' approach avoids making these assumptions by normalisation to a reference material of known age. Uranium zoning has a detrimental effect on the accuracy of LAFT ages. This effect can be removed by counting only those fission tracks located within the laser ablation pit. Alternatively, the uranium heterogeneity may be quantified by fitting multiple ablation spots in some or all the analysed grains, using a (lognormal) distributional assumption for the uranium concentration. LAFT dating is arguably less well suited than the EDM to young and Upoor samples that lack sufficient spontaneous fission tracks to reveal visual evidence for uranium zoning. Such samples occasionally contain no fission tracks at all, resulting in infinite analytical uncertainties. This paper introduces a pragmatic solution to this problem, in which the uranium measurement are converted to 'virtual' induced fission track counts to produce strictly positive ages with finite standard errors. With the age equation and zero-track strategy in place, LAFT ages can be subjected to more sophisticated statistical analysis. Using a logarithmic transformation, these ages can be visualised on radial plots and deconvolved into finite and continuous mixtures. The methods proposed in this paper have been implemented in a software package called IsoplotR that is available free of charge at http://isoplotr.london-geochron.com.

“…This protocol for apatite analyses was established on the basis of numerous experiments carried out at the LEI Lab during the past years, and may be used for simultaneous U-Pb and fission-track in-situ double dating plus multielemental analysis (e.g. Abdullin et al, 2016a and2016b).…”

“…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.
