“…The V-shaped percussion marks identified on quartz were most likely formed by considerable subaqueous transport and subsequent movement due to wave and tidal currents. Similar types of tiny percussion mark are observed in some European, American and Japanese coastal sands, which are generated by fluvial processes with limited recycling of grains under prevailing marine subaqueous environments (Costa et al, 2012;Itamiya et al, 2019;Machado et al, 2016). Flat cleavage surfaces are thought to be a product of intra-granular collisions in higher hydrodynamic energy.…”

“…The linear discriminant analysis and analysis of variance (ANOVA) test are used efficiently to distinguish these sub‐environments (Křížek et al, 2017; Purkait & Majumdar, 2014). However, identifying the grain size distribution analysis involves homogeneity of the sediment sample, which may obscure the depositional events (Machado et al, 2016). Studying grain shape and surface microtexture using scanning electron microscopy (SEM) can provide a plethora of information on the interacting sedimentary processes in these settings (Itamiya et al, 2019; Krinsley & Doornkamp, 1973; J. Li et al, 2021; Madhavaraju et al, 2006; Mahaney, 2002; Mejía‐Ledezma et al, 2020; Vos et al, 2014; Williams & Morgan, 1988).…”

Quartz is a natural rock‐forming mineral, and due to its resistance to weathering, surface patterns on it can be used for assessing physical and chemical processes in coastal environments (Costa et al, 2012, 2013; Hossain et al, 2020; Kalińska‐Nartiša et al, 2017, 2018; Krinsley & Doornkamp, 1973; Machado et al, 2016; Mahaney et al, 2001, 2002). Surface texture characteristics have often been used to determine the transportation process of quartz grains from diverse sedimentary settings, such as fluvial, aeolian, coastal, glacial and lacustrine (Costa et al, 2012, 2013; Hao et al, 2019; Kalińska‐Nartiša et al, 2017; Křížek et al, 2017; Mahaney, 2002; Smith et al, 2018).…”

An attempt has been made to discern sedimentary environments in a tropical coastal setting in Chandipur, India, using variations in grain size. Samples were collected along one 100 m‐long cross‐shore transect extending from the tide/aqueous‐influenced seaward region to the aeolian‐dominated landward region. Various grain size data analysis approaches, like bivariate data plots and discrimination functions, were used to discriminate the sedimentary environments and establish the process of sediment deposition. The analytical results suggest that diverse granulometric parameters translate different sedimentary environments such as tidal flat, beach and dune. Additionally, the surface morphologies of quartz grains were used to understand the evolution of recent mechanical, chemical and mechanical–chemical processes in this tropical coastal region. Changes in the surficial microtextural properties of quartz grains were documented at various sites of all geomorphic units along this transect, from the tidal flat to the dune. One‐way analysis of variance (ANOVA) was used to understand the significant differences in microtextural features between these units. Subaqueous surface textures such as large conchoidal fractures, sharp edges, arcuate steps and straight and curved grooves were dominant in the grains of the tidal flat. The presence of meandering ridges, upturned plates, bulbous edges and adhering particles on quartz gradually increases as the transect ascends landward. Correlation plots between distance and microtextures, along with ANOVA, suggest that aeolian transportation modulated the surface textures. Such assessment of distinct sedimentary characteristics and transport processes may serve as a modern analogue for ancient deposits on the siliciclastic coast.

“…Since the abrasion can easily increase in the presence of high energy by removing the particles adhered to the grain's surface, the presence of adhering particles on the grains denotes a continuous wave action at low energy (Ramos-Vázquez et al 2020). Moreover, the presence of adhering particles on the grains suggests that these grains have undergone post-depositional diagenetic processes in the aquatic environment (Machado et al 2016). The elongated depression (ed) would have most likely developed as a result of chemical attack and precipitation in an underwater environment, grain-to-grain impact, or both.…”

A mineralogical survey was conducted in the Gulf of Guinea sands to assess the transport history, depositional environment, weathering conditions and, provenance. Heavy mineral assemblages are abundant in augite, followed by opaque minerals, diopside, zoisite, enstatite, tourmaline, zircon, rutile, sillimanite, garnet, apatite, hornblende, epidote, kyanite, chloritoid and staurolite. The variety of this minerals show that the sands studied come from the igneous source rocks, mainly from a metamorphic source, in particular the gneisses and basalts, which is consistent with the geology of the study area. The bulk mineralogy detected using XRD and the chemical properties obtained by SEM-EDS reveals that the sands were dominated by quartz. Nineteen microtextures were observed on heavy minerals like hornblende, chloritoid, sillimanite, garnet, augite and staurolite, which were subsequently classi ed as mechanical (13 features), chemical (4 features), and combined mechanical and chemical (2 features) origins. The dominance of mechanical features suggest that the grains underwent high-energy transport. The abundance of angular and subangular heavy minerals indicate distance or nearby source. The mineral composition suggests that the source rocks underwent moderate weathering. The sub-rounded and rounded heavy minerals indicate a long transport. The predominance of heavy minerals in sediments suggest that the nearby source rocks are rich in heavy minerals.

Microtexture and U–Pb geochronology of detrital zircon grains in the Chachalacas beach, Veracruz State, Gulf of Mexico

trace element concentrations, and U-Pb geochronology of detrital zircon grains recovered from the Chachalacas beach in the western Gulf of Mexico were investigated to infer palaeoenvironmental conditions. The mineralogy of bulk sediments revealed the presence of both chemically stable (titano-magnetite, zircon, and quartz) and unstable (amphibole and K-feldspar) minerals. The zircon grain microtextures or surface features were grouped as two types: (a) mechanical origin and (b) mechanical and chemical origin. The mechanical surface features such as V-marks, arc shaped, and meandering steps indicate a high-energy littoral and sub-aqueous marine environment. The chemical surface features like solution pits, precipitation, solution crevasses, adhered particles, and silica pellicle revealed a silica saturated marine environment. The well-rounded zircon grains with bulbous edges are characterized by long transport and aeolian origin. The Th/U ratio, a negative Eu (Eu/Eu* = $0.08-0.72) and positive Ce (Ce/Ce* = >1) anomalies in the chondrite-normalized REE patterns of all zircon grains suggested that they primarily formed from magmatic processes. The detrital zircon grain U-Pb ages showed a wide variation from Cenozoic to Proterozoic with an abundance of Cenozoic ages ($1.59-64.3 Ma; n = 44), interpreted as mixing of beach sediments by a longshore current. The comparison of zircon grain ages of this study with ages reported from the source terranes revealed that the likely source for Cenozoic zircon grains was the Eastern Alkaline Province of Mexico. Similarly, the Mesozoic ($68.5-241.9 Ma) and Palaeozoic ($253.2-284.8 Ma) zircon grains in the Chachalacas beach were possibly derived from the Valle de Huizachal and Mesa Central provinces. Proterozoic ages from $574 to 1846 Ma indicated a probable contribution from the Oaxacan and Chiapas Massif complexes, which are dominated by Grenvillian basement rocks.
