“…Local highs on the pre-Flathead Sandstone topography likely provided a significant amount of detritus to the lower Flathead Sandstone as well. This is supported by the presence of zones in the basal Flathead rich in texturally immature feldspar grains which are found proximal to basement highs of either feldspar-rich crystalline basement (Hubert, 1962) or arkosic strata of the Belt Supergroup (Graham and Suttner, 1974). Regionally, the thickness of the lower Flathead Sandstone is strongly controlled by the topography of the underlying basement, with thicknesses of zero observed over basement highs (Graham and Suttner, 1974;Bell and Middleton, 1978).…”

Mesoproterozoic–Early Cretaceous provenance and paleogeographic evolution of the Northern Rocky Mountains: Insights from the detrital zircon record of the Bridger Range, Montana, USA

The Bridger Range of southwest Montana, USA, preserves one of the most temporally extensive sedimentary sections in North America, with strata ranging from Mesoproterozoic to Cretaceous in age. This study presents new detrital zircon geochronologic data from eight samples collected across this mountain range. Multidimensional scaling and non-negative matrix factorization statistical analyses are used to quantitatively unmix potential sediment sources from these and 54 samples compiled from previous studies on regional correlative strata. We interpret these sources based on reference data from preserved strata with detrital zircon signatures likely representative of ancient sediment sources. We link these sources to their sinks along sediment dispersal pathways interpreted using available paleogeographic constraints. Our results show that Mesoproterozoic strata in southwest Montana contain detritus derived from the nearby craton exposed along the southern margin of the fault-bounded Helena Embayment. Middle Cambrian strata were dominated by the recycling of local sources eroded during the development of the Great Unconformity. In Devonian−Pennsylvanian time, provenance in southwest Montana shifted to more distal sources along the northeastern to southeastern margins of Laurentia, but more western basins received detritus from outboard sources along a tectonically complicated margin. By the Late Jurassic, provenance in the developing retroarc foreland basin system was dominated by Cordilleran magmatic arcs and fold-thrust belt sources to the west. Eastward propagation of the fold-thrust belt caused recycling of Paleozoic and Jurassic detritus into the foreland basin to dominate by the Early Cretaceous.

“…In other samples, the number of transparent heavy minerals recovered (excluding iron oxides and dolomites) varied between 222 and 312. In all samples, the heavy mineral content is dominated by ultra-stable minerals (titanium oxides, zircon and tourmaline), with ZTR ratios (Hubert, 1962) of 75 to 86%. Titanium oxide minerals largely dominate the heavy mineral mix (65 to 75% of grains) and all samples present the same secondary population of apatite (5 to 19%).…”

This study investigates the Provenance of the Barremian-Aptian fluvial clastics exposed in the Essaouira-Agadir Basin which bears an important potential in terms of offshore feeding of reservoir sands. Thin section petrography and SEM, heavy minerals analysis, and detrital zircon dating were conducted and integrated with a large dataset of published low-temperature thermochronology studies to model the associated source-to-sink system. The homogeneity of fingerprints throughout the basin indicated a single provenance for both the northern and southern studied transects. The hinterland analysis based on LTT data revealed that only the Western Meseta and MAM regions were possible source candidates for the Barremian Aptian which was confirmed by detrital zircon geochronology. Heavy mineral populations confirmed that sediment sources were of recycled nature and rock fragment populations in the EAB revealed clasts of limestones, sandstones and volcanic nature only matching with the MAM. The Barremian-Aptian fluvial being sourced from a source-tosink system of moderate size (200-300 km long) with an exclusive or dominant source located in the MAM (western High Atlas) provides the best fit explanation matching with each individual dataset. This likely provided a sand-rich mix of sediment resulting from the erosion of Triassic continental basins, with associated clays resulting from the weathering of basalts and Triassic /Jurassic mudstones. EarthArXiv preprint3 Associated low sea level allowed the direct sediment supply within the slope/offshore domain where seismic imaging suggests the presence of synchronous high reflectivity deep-water channels located in structural lows controlled by diapiric salt movement. An overall NNW drainage deflection is observed offshore the northern part of the basin. The Mesetian domain is likely to be undergoing denudation at the same time and shedding a clastic-rich sediment supply north of the studied region.Due to the offshore NNW deflection of the sediment supply along the northern part of the EAB, mixing between MAM and Mesetian sands is likely offshore Essaouira making the probability of good reservoir sands in the region high.

“…14. The ZTR index (sum of zircon, tourmaline and rutile over total transparent heavy minerals) is utilized to assess the compositional maturity of deposits sampled across the basin and throughout the stratigraphy (Hubert, 1962). Samples for the three studied intervals (Lower Es3, Middle Es3 and Upper Es3) are respectively taken from 44, 85 and 24 wells (Fig.…”
