This paper reconstructs the evolutionary history of Pearl River delta over last 9000 years and investigates land—sea interaction in a large deltaic complex which formed under influence Asian monsoon climate. Specifically, this research examines evolution context three driving mechanisms: (1) rising sea level that influences available accommodation space, (2) fluvial discharge as influenced by climate (3) human activities alter sedimentation within system. Results reveal formation sequences...
This study employs a multiproxy approach in the reconstruction of Holocene monsoon history from sedimentary sequences obtained Pearl River Estuary, southern China. A set modern surface sediment samples were collected within and outside estuary, core was mouth estuary. range environmental variables recorded including water salinity (summer, winter annual average) depth. The diatom results show good relationship with salinity, marine diatoms dominating more distal main estuary freshwater...
Abstract The widespread spatio‐temporal occurrence of ultrahigh‐temperature (UHT) metamorphism in continental crust has been widely documented, but the heat source responsible for generating these extreme conditions over a short period time remains enigmatic. Here, garnet orthogneiss, spinel‐bearing granulite, and gabbronorite from east Khondalite belt, China, have analyzed via integrated geochemistry, U‐Pb zircon isotope geochronology, phase equilibria modeling to shed light on timing...
Abstract The increase in initial Hf isotopes identified early Mesoarchean detrital zircon is commonly interpreted as a reflection of the geodynamic transition from stagnant‐lid to mobile‐lid tectonics. However, given lack petrogenetic context, interpreting may lead spurious conclusions. In this contribution, we use U‐Pb‐Hf‐O isotopic and bulk rock compositions newly 3.05–2.9 Ga granitoids SW Yangtze Block posit petrogenesis within an isotopically juvenile magmatic system. A statistical...
Electrolyte modulation can enhance the performance of electrocatalysts for oxygen evolution reaction (OER) by tailoring electrocatalyst-electrolyte interface, but role anion additives remains controversial. Herein, we report our findings on unraveling effects oxyanions (NO3–, SO42–, and PO43–) identifying Fe impurities as key factor driving OER activity enhancement in Ni hydr(oxy)oxide model catalysts. impurities, introduced via oxyanion salts, significantly activity, while themselves have...
Abstract This study examines the sedimentary evidence of human activities during last 4000 years in Pearl River deltaic area. The analyses are focused on indentifying agricultural signatures present record and establishing timing a change from simple, rice‐based agriculture to more advanced, diverse agriculture. examination is based modern sediment plant samples core collected include particle size diatom analysis determine environmental conditions that were associated with period...
Abstract Some mafic granulites in the Sanggan area of northern Trans‐North China Orogen ( TNCO ) have a relatively simple mineralogy with low energy grain shapes that are compatible an assumption equilibrium, but rock‐forming minerals show variations composition create challenges for thermobarometry. The granulites, which occur as apparently disrupted dyke‐like bodies tonalite–trondhjemite–granodiorite gneisses, divided into two types based on petrography and chemical composition. Type 1...
Earth's earliest continental crust is dominated by tonalite-trondhjemite-granodiorite (TTG) suites, making these rocks key to unlocking the global geodynamic regime operating during Archaean (4.0-2.5 billion years ago [Ga]). The tectonic setting of TTG magmatism controversial, with hypotheses arguing both for and against subduction. Here we conduct petrological modeling over a range pressure-temperature conditions relevant geothermal gradient. Using an average enriched basaltic source...
Abstract An Al‐rich, quartz‐absent corundum‐bearing pelitic granulite is reported for the first time at Diebusige complex in Alxa Block western part of Khondalite Belt (KB), North China Craton (NCC). A detailed petrographic study shows that a quartz‐present domain occurs porphyroblastic garnet cores from granulite, with prograde metamorphic mineral assemblage (M 1 ) + plagioclase quartz biotite spinel rutile ± melt, and matrix this rock, preserved peak 2 corundum K‐feldspar melt retrograde 3...
Abstract This paper examines the Late Quaternary evolutionary history of northern coast South China Sea by reviewing geological evidence from this coast. Results show that: (1) a lithostratigraphy with two marine sequences is observed in deltaic basins Song Hong, Pearl and Han rivers, these are all bounded active faults; (2) whilst upper sequence belongs to present interglacial or past 10.5 ka, lower older was most likely deposited during high sea level last period, c. 126–120 ka; (3) burial...
Abstract The start of the Paleoproterozoic supercontinent cycle is typically taken as initiation orogenesis at ca. 2.1 Ga leading to assembly Earth's first supercontinent, Columbia. However, dearth 2.5–2.2 geological records makes it difficult deduce tectonic factors during onset cycle. petrogenesis tonalite–trondhjemite–granodiorite (TTG) provides useful proxies for tracing prevailing geodynamic regimes early continental evolution. marked decreases TTG and other magmatism occurred across...
