Recurrent sea-level changes are reflected in the formation of coastal landforms; estuary, lakes, lagoons and barrier beaches during the late Quaternary period along the Kerala coast, SW India. The sediment core from these landforms was addressed for sediment lithofacies, geochemical parameters and associated foraminiferal assemblages to reconstruct the late Quaternary environment. The textural characteristics

Cretaceous tectonic events and Cenozoic geodynamics of the central South China Block are still under debate. A long-term extensional regime or two extension-contraction tectonic cycles were proposed for the Cretaceous tectonic evolution. While Cenozoic geodynamics of the central South China Block were ascribed to the Pacific subduction or the far field effect of the India-Asia collision. Kinematic

A typical shallowly buried (800∼2000 m burial depth) coarse-clastic, nonmarine, fan-deltaic reservoir is well developed in the Eocene Shahejie Formation, Damintun Sag, Bohai Bay Basin, China. In this study, diagenesis and its control on the reservoir quality of fan-deltaic sandstones and conglomerates in the Shahejie Formation were investigated in detail by petrographic and geochemical analyses, including

South China is characterized by enormous volumes of igneous rocks generated by multiple stages of magmatism. Five large-scale metallogenic belts with many world-class deposits have been discovered, demonstrating great potential for prospecting new resources. To restrict the South China metallogenic cognition the main problems include the types and metal associations of the deposits, factors controlling

The Bangong-Nujiang Ocean (BNO) separated the Lhasa and Qiangtang blocks in Tibet during the Mesozoic. Whether it separated the Tengchong and Baoshan blocks and how it evolved remain debated. The sedimentary rocks from the Middle Jurassic Mengjia and Liuwan formations, Late Jurassic Longhai Formation, and Early Cretaceous Longkan Formation of the western Baoshan block serve to investigate these issues

The Sanjiang Tethys region in SW China lies in the tectonic junction of the Tethys domain, and represents a key precious/base metal province in China. Based on a compilation of studies from the past decades on the formation, evolution, and metallogenesis of the tectonic units in the region, we proposed a multi-arc-basin-terrane (MABT) structural framework for the Paleo-Tethys Sanjiang region. Convergence

Earth’s evolution involves deep, hot rocks rising upward by convection to near-surface environments, as well as the unique scenarios such as the formation and breakup of Gondwana and Pangea. These processes have been well recorded by the widely distributed magmatism. To understand the tectonic evolution and Gondwana assembly, we compiled early Paleozoic zircon U–Pb ages (n = 67), in-situ zircon Hf

The Andaman Sea has experienced a number of earthquake swarms as a result of complex tectonics arising from oblique subduction, active volcanic arc, the backarc spreading center, and sliver fault systems. One of the most energetic offshore earthquake swarms occurred in the off Nicobar region of the Andaman Sea in January 2005, following the 26th December 2004 (9.1 Mw) Sumatra megathrust event. After

As one of the most ancient cratons in Asia, the North China Craton (NCC) provides an opportunity to examine the evolution of the early earth. However, it is poorly known about the tectonic setting of the Eastern Block of the NCC at 2.47-2.17 Ga. In this study, zircon U-Pb dating was conducted to constrain the provenance, depositional age, and depositional environment of the Langzishan Formation in

Well-preserved Middle Jurassic (upper Bajocian to lower Bathonian) radiolarian assemblages from bedded cherts constrain the age of cherts associated with the Dajiweng ophiolite in the northern sub-belt of the western section of the Yarlung Tsangpo suture zone (YTSZ). Sixty-one species belonging to 39 genera are recognized and illustrated. They represent the most diverse Middle Jurassic radiolarian

The prolonged complex geological evolutionary history of South China Craton is documented in a well-preserved rock record that comprises an Archean to Neoproterozoic crystalline basement (metamorphosed igneous and sedimentary rocks) and Phanerozoic supracrustal rocks. Some of the global Precambrian tectonic events, such as the formation and breakup of Columbia and Rodinia supercontinents are also represented

Whilst geophysical exploration and petrological analyses imply that the Early Cretaceous North China Craton (NCC) destruction may have impacted the Taihang Shan in the central NCC, associated evidence indicative of contemporary upper-crustal extension is lacking. We herein investigate the formation mechanism and timing of the allochthons that consist of Mesoproterozoic to Mesozoic sedimentary rocks

The South China Sea is located at the junction of the Eurasian, Indian, Australian, and Pacific plates, and thus its evolution is complex and the nature of its sub-ridge mantle remains unclear. Here we present new iron (Fe) isotopic data for mid-ocean ridge and intraplate basalts from the South China Sea region, in order to examine the origins of compositional heterogeneity in the sub-ridge mantle

A combined study of garnet and zircon from the same growth stages can provide effective constraints on the pressure–temperature-time path of metamorphic processes. This is illustrated by distinguishing different episodes of garnet and zircon in metabasites from North Qaidam. Two different garnet domains grown under eclogite- and granulite-facies conditions were recognized to have different trace elements

This introduction outlines the papers collected in the special issue “Mesozoic magmatism and mineralization in Southeastern China”. These papers focus on the spatiotemporal distributions, petrogenesis, geochronology, mineralization and tectonic settings of the Mesozoic granitic rocks in SE China, and they represent the new research progress and further understanding on the granitic magmatism and associated

This review examines the development of carbonates and their enclosing siliciclastic sediments, from the Late Eocene until the end of the Oligocene, in eastern Java and the southern Makassar Straits. Five genetic sedimentary sequences are recognised, which correlate to other studies in the area, and points to an episodic sedimentary history controlled by tectonism. An additional intra Late Miocene

The phenomenon of Lithosphere-Ionosphere coupling is a popular topic for researchers for the last two decades. This study aims to analyze the seismo-ionospheric anomalies (SIAs) in East Asia induced by the M > 6 earthquakes (EQs) from Total Electron Content (TEC) of permanent IGS stations operating around the vicinity of the corresponding epicenters by considering a case study of two successive EQs

Accretionary-collisional events occurred at the western margin of the Tuva-Mongolian microcontinent are used to explain the largely contradictory Cambrian geodynamic history of the western Central Asian Orogenic Belt (CAOB). This study presents new data for the Erzin metamorphic complex in order to constrain the petrogenesis and tectonic implications of the metamorphic rocks in this complex. The Erzin

The Sichuan-Yunan-Guizhou triangle region contains numerous economically important carbonate-hosted Zn-Pb deposits that occur in the Late Indosinian thrust and fold system rather than foreland basin. In this paper, we investigate the thrust-controlled Zhugongtang deposit (>30.0 Mt ores @ 6.76 wt.% Zn and 2.27 wt.% Pb) as a case study, using ore deposit geology, in-situ trace elements and isotopes in

Zircon ages and geochemistry are presented for igneous rocks from SW Vietnam and S Cambodia. Four main age groupings occur: Cretaceous (107-75 Ma), Early Jurassic (195 Ma), Late Triassic (230-222 Ma), and Permian (294-265 Ma). Cretaceous and Jurassic samples are amphibole-bearing biotite granodiorites to biotite granites and occur mainly east of the Kampot Fold Belt. Pre-Cretaceous samples occur within

The Alborz Mountain accommodates some of the convergence between Central Iran and Eurasia, is characterized by active range-parallel fold and thrust structures. At present, the kinematics of the range involves a strain partitioning mechanism and clockwise rotation of the South Caspian Basin. Range-parallel, left-lateral strikeslip faulting dominates the central part of the mountain range, while reverse

Early Mesozoic volcanic rocks in northwestern Laos are rarely reported and important for investigating the Paleotethyan tectonic evolution and regional correlation in SE Asia. In this study, New zircon ages and whole-rock geochemical data are presented for the newly identified volcanic rocks in northwestern Laos. Twelve volcanic rocks yield zircon U–Pb ages of 228–234 Ma. The volcanic rocks in northwestern

To explore the paleoenvironmental changes in SE Asia during the late Neogene, we examined the stable carbon and oxygen isotope compositions of tooth enamel from mammals of the late Pliocene/earliest Pleistocene Gwebin area in central Myanmar and compared the results with those of the latest Miocene Chaingzauk mammals in Myanmar. The stable carbon isotope values (δ13C) of Gwebin mammals indicate that

To assess the environmental impacts of offshore wind farming and sea sand mining, coastal areas are zoned on the basis of their natural oceanographic characteristics. Textural and geochemical properties of South Korean coastal sediments, including mean grain size (Mz), CaCO3 and organic-matter contents, and metal concentrations (Al, K, Ba, rare earth elements, Zr, etc.), were analyzed and categorized

Field relations, microstructures, phase petrology, elemental geochemistry, and zircon U-Pb geochronology of migmatites and (undeformed) granites (sensu lato) from the Central Bundelkhand Tectonic Zone (CBTZ) of the Bundelkhand Craton, central India are investigated to understand the age and origin of these rocks. Anatexis of felsic proto-crust produced in situ leucocratic melts with entrained residual
