“…Myally subgroup by the Prize supersequence between 1695 and 1688 Ma was insufficient to cause diagenesis of the Myally subgroup; a maximum of 1,800 m of Prize supersequence sediments are preserved (Jackson et al, , 2005Page et al, 2000;Neumann et al, 2006). A third incision event between 1688 and 1670 Ma at the base of the Gun supersequence removed some to all of the Prize supersequence, such that in places all three erosion surfaces amalgamated (Fig.…”

“…14c). Based on stratigraphic relationships, a minimum of 250 m and as much as 2,000 m of sediment could have been removed at this boundary (Jackson et al, 2005). Although the addition of ~2,600 m of sediment and basalt during the development of the Calvert superbasin may have been enough to cause diagenesis of the deepest units of the Myally subgroup, the subsequent erosion events between 1700 and 1695 Ma and then again between 1688 and 1668 Ma promoted the precipitation of quartz overgrowth cements which arrested aquifer development.…”

The western succession of the Mount Isa basin in northwest Queensland hosts four supergiant Zn-Pb ± Cu deposits and numerous smaller Cu and Zn-Pb deposits. Mineralization is primarily hosted in carbonaceous and calcareous shales and siltstones belonging to the 1670 to 1575 Ma Isa superbasin, but little is known about the source of metals that formed these deposits. The underlying clastic and volcanic successions belonging to the 1800 to 1750 Ma Leichhardt superbasin and the 1735 to 1690 Ma Calvert superbasin are potential metal source rocks and host a variety of diagenetic minerals that preserve geochemical information about the evolution of brines in the basin.Quartz overgrowths and pressure solution features formed during shallow burial in all clastic lithologic units but are particularly common in the well-sorted, marine-dominated units that became aquitards due to the porosity-occluding diagenetic cement. Microthermometry on fluid inclusions in the quartz overgrowths indicates formation between 100º and 174ºC from a low-salinity, 2.7 to 9.1 wt percent NaCl equiv fluid (fluid 1). These data together with sequence stratigraphic mapping, basin reconstruction, and stable isotope values from the quartz overgrowths show that the diagenetic aquitards formed at <5-km depth. Illite and chlorite formed locally in some of the diagenetic aquitards and preserve δ 18 Ofluid and δDfluid values of 4.5 ± 4.2 and -34 ± 14 per mil, respectively, indicating evolution from a seawater-dominated source. Silicate dissolution and the widespread formation of diagenetic illite and chlorite occurred late, during deep burial diagenesis and primarily in the proximal fluvial lithologic units. These units are recognized as diagenetic aquifers and they occur adjacent to and within the Eastern Creek and Fiery Creek Volcanics where metals could have been sourced. Basin reconstruction shows that the diagenetic aquifers formed at depths between 5 and 10 km. Illite and chlorite extracted from the diagenetic aquifers have distinct δ 18 Ofluid and δDfluid values of 4.5 ± 2.8 and -63 ± 11 per mil, respectively, indicating evolution from a meteoric fluid with a variable marine contribution. These isotopic values cannot be differentiated from published isotopic values of fluid inclusion water in quartz-dolomite-chalcopyrite veins at Mount Isa or sphalerite and illite from the Century Zn deposit and the Zn lodes from the Burketown mineral field. This suggests that the diagenetic aquifers were likely source rocks for metals in the deposits in the Mount Isa basin. In contrast to the phyllosilicates in the diagenetic aquifers, regional dolomitic grainstones and dolomudstones in the Lawn Hill platform precipitated from fluids with δ 18 Ofluid between -2.6 and 1.1 per mil and δ 13 Cfluid between -8.6 and -3.9 per mil. This suggests that these units did not contribute to the ore-forming brines.Quartz veins formed during the later diagenetic history in the Mount Isa basin from a low-salinity brine, between 2.7 and 10.4 wt percent NaCl equiv (fluid 2).

“…Maximum depositional ages obtained from the youngest zircon age populations are now known for Proterozoic basins on many continents (e.g., Ross et al, 1992;Rainbird et al, 1997;Evans et al, 2000;Southgate et al, 2000;Smithies et al, 2001;Goodge et al, 2002;Ross and Ville neuve, 2003;Jackson et al, 2005;Maclean et al, 2006;Cawood et al, 2007;Cross and Crispe, 2007;Link et al, 2007;Amato et al, 2008), although they do not always yield an age that represents the timing of deposition. Detrital zircon U-Pb age populations also provide fundamental provenance information toward under standing the paleogeographic development of Laurentia's Proterozoic rift margins, although data are limited for middle Neoproterozoic Laurentia (Rainbird et al, 1997;Stewart et al, 2001;Cawood et al, 2007).…”

U-Pb detrital zircon analyses provide a new maximum depositional age constraint on the Uinta Mountain Group (UMG) andcorrelative Big Cottonwood Formation (BCF) of Utah, and signifi cantly enhance our insights on the mid-Neoproterozoic paleogeographic and tectonic setting of western Laurentia. A sandstone interval of the Outlaw Trail formation with a youngest population (n = 4) of detrital zircons, from a sampling of 128 detrital zircon grains, yields a concordia age of 766 ± 5 Ma. This defi nes a maximum age for deposition of the lowermiddle Uinta Mountain Group in the eastern Uinta Mountains and indicates that the group is no older than middle Neoproterozoic in age (i.e., Cryogenian). These data support a long-proposed correlation with the Chuar Group of Grand Canyon (youngest age 742 Ma ± 6 Ma), which, like the Uinta Mountain Group and Big Cottonwood Formation, records nonmagmatic intracratonic extension. This suggests a ~742 to ≤766 Ma extensional phase in Utah and Arizona that preceded the regional rift episode (~670-720 Ma), which led to development of the Cordilleran passive margin. This is likely an intracratonic response to an early rift phase of Rodinia. Further, because the Chuar Group and the Uinta Mountain Group-Big Cottonwood Formation strata record intracratonic marine deposition, this correlation suggests a regional ~740-770 Ma transgression onto western Laurentia.The detrital grain-age distributions from 12 samples include the following grain-age populations and interpreted provenance: 2.5-2.7 Ga (late Archean southern Wyoming province); 1.6-1.8 Ga (Paleoproterozoic Yavapai province); 1.5-1.6 Ga (Early Meso proterozoic North American magmatic gap), 1.4-1.45 Ga (Colorado province A-type granite-rhyolite belt); 0.93-1.2 Ga (eastern Grenvillian orogen); and midNeoproterozoic volcanic grains (766 Ma). Sediment was transported by: (1) a major longitudinal west-fl owing river system tapping the Grenville orogen, (2) local southfl owing drainages off the southern Wyoming craton, and (3) northerly and westerly fl owing marine currents. The Uinta Mountain Group river system was one of several major transcontinental drainages that delivered Grenvillian zircon grains to the protoPacifi c Ocean. We propose that this river system ultimately supplied sediment to periGondwanan margins along the proto-Pacifi c to Antarctica, Australia, and South America, providing an alternative source for explaining the problematic provenance of Grenvillian grains in these areas.
