“…The subrounded shapes of the zircon grains are surprising given the proximity (a few hundred kilometers) of the depositional site to the plutonic source. The subrounded shape is interpreted to indicate extensive reworking in tidal sand bodies as opposed to less reworking in the fluvial systems studied by Link et al (2005) and Zoleikhaei et al (2016).…”

“…Well-rounded zircon grains increased significantly after the Quaternary, as shown in Figure 7. Zircon roundness can be improved by physical abrasion after long-distance transport and recycling [15,[47][48][49]. The detrital zircon age spectra of the Quaternary sediments showed multiple peaks with higher abundance of the Neoproterozoic and Paleoproterozoic, which further implied that the sediments of the Yangtze Delta likely originated from the Tibetan Plateau [21].…”

Morphology of Detrital Zircon as a Fingerprint to Trace Sediment Provenance: Case Study of the Yangtze Delta

Deltaic areas and marginal seas are important archives that document information on regional tectonic movement, sea level rise, river evolution, and climate change. Here, sediment samples from boreholes of the Yangtze Delta and the modern Yangtze drainage were collected. A quantitative analysis of detrital zircon morphology was used to discuss the provenance evolution of the Yangtze Delta. This research demonstrated that a dramatic change in sediment provenance occurred in the transition from the Pliocene to Quaternary. Zircon grains in the Pliocene sediments featured euhedral crystals with large elongation (>3 accounted for 13.2%) and were closely matched to tributary samples in the Lower Yangtze (>3 accounted for 11.3%), suggesting sediment provenance from the proximal river basin. However, most detrital zircon grains of the Quaternary samples exhibited lower values of elongation and increased roundness (rounded grains were 9.4%), which was similar to those found in the modern Yangtze mainstream (rounded grains were 12.5%) and the middle tributaries (rounded grains were 7.0%). The decrease in zircon elongation and improvement of its roundness in the Quaternary strata implied that the Yangtze Delta received sediments of different provenance that originated from the Middle-Upper Yangtze basin due to the uplift of the Tibetan Plateau. Statistical analysis of detrital zircon morphology has proven useful for studying the source-to-sink of sediments.Minerals 2019, 9, 438 2 of 15 intuitively determine zircon parent rocks and are potential fingerprints to be applied in sediment provenance analysis [13][14][15][16][17].Serving as an important depocenter of the Eastern China, the Yangtze Delta has preserved valuable information on sediment sources related to landform and river evolution [5,18,19]. Using different methods of clay mineral analysis, geochemistry, magnetic properties, single mineral geochronology (zircon, monazite age spectra), previous studies have identified a significant change in sediment provenance at the Pliocene-Quaternary transition [20][21][22][23]. However, sediment provenance evolution in the deltaic area is still controversial [22]. There is neither a consensus about the exact source of the Pliocene strata in the Yangtze Delta nor about the time when the Upper Yangtze sediments arrived at the delta. Different studies proposed that the Upper Yangtze sediment arrived either early in the Pliocene [21,24], in the Early-Middle Pleistocene [22,23,[25][26][27], or later in the late Pleistocene [28,29]. For these previous studies, only one borehole was used to represent the entire area of the Yangtze Delta, which may have resulted in different interpretations due to the limitations of the different methods. This is not only because of the vast area of Yangtze Delta but also because of its complex sedimentary strata.In order to extract the exact sediment provenance, several boreholes in different regions of the study area should be systematically analysed and compared to potential source sediments within ...

“…Zoleikhaei et al . [] demonstrated that first‐cycle detrital zircon grains retain their original morphology even after being subject to hundreds of kilometers of fluvial transport and littoral reworking. They suggest that well‐rounded grains in ancient strata are likely to have experienced several sedimentary cycles.…”

Detrital zircon surface microtextures, geochronologic U‐Pb data, and tectonic subsidence analysis from Upper Jurassic to Paleocene strata in the Black Hills of South Dakota reveal provenance variations in the distal portion of the Cordillera foreland basin in response to tectonic events along the outboard margin of western North America. During Late Jurassic to Early Cretaceous time, nonmarine strata record initially low rates of tectonic subsidence that facilitated widespread recycling of older foreland basin strata in eolian and fluvial systems that dispersed sediment to the northeast, with minimal sediment derived from the thrust belt. By middle Cretaceous time, marine inundation reflects increased subsidence rates coincident with a change to eastern sediment sources. Lowstand Albian fluvial systems in the Black Hills may have been linked to fluvial systems upstream in the midcontinent and downstream in the Bighorn Basin in Wyoming. During latest Cretaceous time, tectonic uplift in the study area reflects dynamic processes related to Laramide low‐angle subduction that, relative to other basins to the west, was more influential due to the greater distance from the thrust load. Provenance data from Maastrichtian and lower Paleocene strata indicate a change back to western sources that included the Idaho‐Montana batholith and exhumed Belt Supergroup. This study provides a significant contribution to the growing database that is refining the tectonics and continental‐scale sediment dispersal patterns in North America during Late Jurassic‐early Paleocene time. In addition, it demonstrates the merit of using detrital zircon grain shape and surface microtextures to aid in provenance interpretations.
