TL;DR: In this paper, the authors determined that the host rocks to the amber are Tertiary (most said Eocene) in age, and this conclusion has been widely quoted in the literature.

TL;DR: The Sanandaj-Sirjan Zone contains the metamorphic core of the Zagros continental collision zone in western Iran as discussed by the authors, and the zone has been subdivided into the following from southwest to northeast: an outer belt of imbricate thrust slices (radiolarite, Bisotun, ophiolite and marginal sub-zones, which consist of Mesozoic deep-marine sediments, shallow-marine carbonates, oceanic crust and volcanic arc, respectively) and an inner complexly deformed sub-zone (late Palaeozo

TL;DR: In this article, the authors present new data and interpretations on the Neogene tectonics of the Shan scarp area (central Myanmar) and its relationship with the India-Indochina oblique convergence.

TL;DR: In this paper, a new plate tectonic model, in contrast to the earlier one of Yedekar et al. is proposed, in which a northward dipping subduction system leading to continent-continent collision explains the growth and assembly of the CITZ.

TL;DR: Wang et al. as mentioned in this paper have presented a summary of the weathering characteristics and zoning of granite weathering profiles in South China and discusses their engineering and geological properties, which are important in the design and construction of civil engineering projects.

TL;DR: The Tethyan sedimentary sequence of central Nepal has been affected by three phases of folding (D1,D 2, and D4) with contrasting vergence, interspersed by two major extensional events (D3 and D5).

TL;DR: In this paper, the authors presented new geochronological, petrological, geochemical and isotopic data for granitic and related rocks from the Aravalli Craton, Rajasthan, northwestern India.

TL;DR: In this paper, the authors presented new U-Pb zircon ages determined with Sensitive High-Resolution Ion MicroProbe (SHRIMP) for nine plutonic rocks or orthogneisses and one paragneiss from the Higo and Maana belts (here referred to as the paleo-Ryoke belt) in southwest Japan, and the South Kitakami belt in northeast Japan.

TL;DR: The active volcanoes in China are located in the Changbaishan area, Jingbo Lake, Wudalianchi, Tengchong and Yutian as discussed by the authors.

TL;DR: In this article, six granitoid plutons, occurring in the northern part of the Delhi Fold Belt, NW India, have been chemically dated using an electron microprobe, and the geochemical signatures of these granitoids are consistent with an extensional tectonic regime.

TL;DR: The Sabzevar ophiolite is a highly dismembered ophiorite complex located along the northern boundary of the central Iranian microcontinent (CIM), and is one of the internal Iranian group of Ophiolites and colored melanges as discussed by the authors.

TL;DR: In this paper, the freezing/thawing processes and the temperature distribution were strongly influenced by soil moisture content, and the abrupt increase/decrease of net atmospheric heating synchronized with the thawing/freezing of soil indicates that these processes may strongly influence the seasonal transition on the Qinghai-Xizang (Tibetan) Plateau.

TL;DR: A total of 592 heat flow measurements, ranging from 8 to 192 mW/m(2), have been collected in the South China Sea (SCS) as mentioned in this paper.

TL;DR: This article reported new single zircon evaporation ages and Nd isotopic systematics for dioritic to granodioritic gneisses of the Kadugannawa Complex of central Sri Lanka which record a period of magmatic arc activity between 1006 and 881 Ma and show this complex to be part of the Wanni domain.

TL;DR: In this article, the Luzhenguan and Foziling complexes of the Dabie ultrahigh-pressure collisional belt were investigated and detrital zircons of Archean-to-Paleozoic ages were characterized for the Yangtze Block.

TL;DR: A detailed overview of biotic assemblages recovered from the Deccan trap intercalated sedimentary sequences (infra- and intertrappean beds) of peninsular India as a result of extensive research done during the last 20 years is given in this article.

TL;DR: The Rengali Province in northern India is a distinct lithological, structural and metamorphic belt bound by major shear zones between the Singhbhum Province and the northern Eastern Ghats Belt and the NE part of the Bhandara Province.

TL;DR: The relationship between deformation and metamorphism shows that the metamorphic peak was syn-to post-tectonic in relation to the main ductile shearing event as discussed by the authors.

TL;DR: In this paper, zircon grains separated from three samples of the orthogneiss complex have been dated to establish the protolith age and the timing of high-grade tectonothermal events in the complex.

TL;DR: The Xiaojiang Fault Zone as discussed by the authors is one of the most active fault zones of the southeastern edge of the Tibetan Plateau, which is a N-S trending 400 km long fault zone defines the southern part of the Sichuan-Yunnan Block.

TL;DR: This article identified 13 planktonic foraminiferal zones assigned to the late Aptian to early Campanian in the Oyubari and Haboro-Kotanbetsu areas.

TL;DR: In this paper, the Yezo forearc basin has been studied and two second-order shallowing-upward cycles are recognized in Hokkaido but are obscure in north Honshu.

TL;DR: The Pranhita-Godavari Gondwana rift (PGR) has a co-genetic relationship with Permo-Triassic reactivation of the Narmada-Son Geofracture (NSG), which restricted the northwestward propagation of the PGR as discussed by the authors.

TL;DR: In this paper, the authors presented a detailed description of sedimentary facies with high-resolution radiocarbon dating for the latest Pleistocene-Holocene sediments of the Song Hong delta.

TL;DR: Fossil Medusoid genera resembling Ediacaria (Sprigg 1947 ) and Hiemalora (Fedonkin 1982 ) and having distinctive Ediacaran affinity have been discovered in a shale horizon occurring at the base of the Bhander Group, the uppermost unit of the Vindhyan Supergroup of central India.

TL;DR: In this paper, stable isotope (S, O, H, and C) studies were performed to determine the origin of the ore-forming solutions, and their important components (e.g. sulfur and carbon).

TL;DR: In this article, the West Kunlun basin is shown to have experienced a rapid and accelerated uplift from Late Miocene to Early Pleistocene times by a tectonic pulse, which resulted in tilting of the molasse and underlying sediments at high-angle towards the Tarim Basin.

TL;DR: In the Tianchi volcanic zone, Changbai Mountains, northeast China, since late Pliocene time as mentioned in this paper, mafic volcanic rocks have erupted in this zone, and the conduit for upwelling was not coincident with the NE-striking regional faults, but seem to be confined to a deep-seated NW-WNW-striving fault zone.
