“…Geochemical data of the studied samples from Moussa et al (2008Moussa et al ( ). et al, 2012Ali et al, 2014). Nevertheless, the abundance of preNeoproterozoic zircons in especially Cryogenian volcanic sequences suggests that some input of older materials occurred (Ali et al, 2009;.…”

Detrital zircon U–Pb–Hf data from Cambrian sandstones of the Ougarta Mountains Algeria: Implication for palaeoenvironment

We report new detrital zircon U-Pb ages and Hf isotopic signatures of detrital zircons in Cambrian sedimentary rocks from the Ougarta Mountains of Algeria in the West African Craton (WAC) in order to provide constraints on the palaeo-catchments of the Early Palaeozoic river systems draining Gondwana. The Cambrian sedimentary samples from the Ougarta Mountains have near-identical age spectra with a dominant age peak at 618 Ma and an additional age peak at 2,035 Ma. The oldest detrital zircon grain is 3,407 Ma. The εHf (t) values of the 618 Ma age peak spans from εHf (t) +12 to −25 with a dominant mode at −1; the εHf (t) of the Palaeoproterozoic zircon ranges from 6 to −27 with an average of −10; the pre-2,300 Ma zircon Hf lie along a crustal evolution trajectory (176 Lu/ 177 Hf = 0.01) back to the depleted mantle at 3,100 Ma. The maximum depositional age of the sandstones in the Sebkhet el Melah Formation is constrained by the youngest detrital zircon age of 559 ± 13 Ma and by the underlying volcaniclastic rocks dated at 555 ± 7 Ma (Late Ediacaran to the Early Cambrian). The 618 and 2,035 Ma age peaks are consistent with a proximal provenance from the WAC, and it is possible that recycling of eroded material from the Cadomian arc and Pan-African rocks may have been a potential source of the Ediacaran detrital zircons analysed herein. There were four (0.9%) Stenian detrital zircons identified in this study, and our results are consistent with the lack of WAC Stenian detrital zircon noted in previous studies, except those reported from a single Middle Cambrian sample in Morocco. Correlative sedimentary successions further to the east contain ubiquitous ca. 1.0 Ga detrital zircon that was likely supplied from the Trans-Gondwana Mountain chain. It is noteworthy that the WAC and Sahara Metacraton are surrounded on three sides by Neoproterozoic orogenic systems, with the Rokelide, Dahomeyide, Pharuside, Anti-Atlas, and Brasiliano orogens (reconstructed position from Gondwana palaeogeography) around the WAC and the Dahomeyide, Pharuside, East African orogen, and Oubangides orogens around the Sahara Metacraton. We posit these orogenic belts acted as drainage divides that controlled sediment routing pathways. Additionally, the occurrence of Stenian detrital zircon in Morocco could be explained by longshore drift coming from the east (present-day coordinates).

“…Since then, thousands of zircon UePb and Hf analyses from the basement rocks of the ANS and detrital zircon derived there from display a tight range of εHf during the time period in question, with the 90th percentile of the data ranging from þ13 to þ2 (Fig. 4a) (Be'eri-Shlevin et al, 2010;Morag et al, 2011Morag et al, , 2012Ali et al, 2012Ali et al, , 2013Ali et al, , 2014Ali et al, , 2015aBe'eri-Shlevin et al, 2013;Iizuka et al, 2013a,b;Robinson et al, 2014).

“…The Cathaysia Block of the South China craton, which is thought to have been located off the northern Indian margin of Gondwana (Yao et al, 2014a,b), is another likely source region of the GHS because the two shared a common w980 Ma zircon age population in their coeval late-Neoproterozoic to early-Paleozoic sedimentary Morag et al, 2011Morag et al, , 2012Ali et al, 2012Ali et al, , 2013Ali et al, , 2014Ali et al, , 2015aIizuka et al, 2013a,b;Robinson et al, 2014).

a b s t r a c tThe metamorphic core of the Himalaya is composed of Indian cratonic rocks with two distinct crustal affinities that are defined by radiogenic isotopic geochemistry and detrital zircon age spectra. One is derived predominantly from the Paleoproterozoic and Archean rocks of the Indian cratonic interior and is either represented as metamorphosed sedimentary rocks of the Lesser Himalayan Sequence (LHS) or as slices of the distal cratonic margin. The other is the Greater Himalayan Sequence (GHS) whose provenance is less clear and has an enigmatic affinity. Here we present new detrital zircon Hf analyses from LHS and GHS samples spanning over 1000 km along the orogen that respectively show a striking similarity in age spectra and Hf isotope ratios. Within the GHS, the zircon age populations at 2800e2500 Ma,
