An overview and tectonic synthesis of the pre‐Tertiary very‐high‐pressure metamorphic and associated rocks of Java, Sulawesi and Kalimantan, IndonesiaHigh‐pressure metamorphic rocks are widely distributed in Cretaceous accretionary complexes throughout Java, Sulawesi (formerly Celebes) and southeast Kalimantan (Indonesian Borneo). Many of these rocks occur as imbricate slices of carbonate, quartzose and pelitic schists of shallow marine or continental margin parentage, interthrust with subordinate basic schists and serpentinite. They ar... ... hiện toàn bộ

An outline of the petrology, structure and age of the Pompangeo Schist Complex of central Sulawesi, IndonesiaVariably dismembered and metamorphosed accretionary complexes constitute the basement of much of the Indonesian island of Sulawesi. The most extensive of these is the Pompangeo Schist Complex, which crops out over ∼ 5000 km2 in central Sulawesi, and is predominantly composed of interbanded phyllitic marble, calcareous phyllite, graphitic schist and quartzite; rocks of ... ... hiện toàn bộ

Evolution of an accretionary complex along the north arm of the Island of Sulawesi, IndonesiaAbstract Seismic reflections across the accretionary prism of the North Sulawesi provide excellent images of the various structural domains landward of the frontal thrust. The structural domain in the accretionary prism area of the North Sulawesi Trench can be divided into four zones: (i) trench area; (ii) Zone A; (iii) Zone B; and (iv) Zone C. Zone A is an active i...

Metasomatized harzburgite xenoliths from Avacha volcano as fragments of mantle wedge of the Kamchatka arc: Implication for the metasomatic agentAbstract Abundant peridotite xenoliths have been found in pyroclasitics of Avacha (Avachinsky) volcano, the south Kamchatka arc, Russia. They are mostly refractory harzburgite with or without clinopyroxene: the Fo of olivine and Cr/(Cr + Al) atomic ratio of spinel range from 91 to 92 and from 0.5 to 0.7, respectively. They are metasomatized to various extents, and t...

New advances of seismic tomography and its applications to subduction zones and earthquake fault zones: A reviewAbstract There have been significant advances in the theory and applications of seismic tomography in the last decade. These include the refinements in the model parameterization, 3‐D ray tracing, inversion algorithm, resolution and error analyses, joint use of local, regional and teleseismic data, and the addition of converted and reflected waves in the tomographic ...

Late Cretaceous paleoenvironment and lake level fluctuation in the Songliao Basin, northeastern ChinaAbstract Study of Late Cretaceous lacustrine sedimentary strata in the eastern Songliao Basin, China revealed that the paleoclimate was relatively arid and hot during sedimentation of the upper Santonian of the Yaojia Formation, but became relatively humid and warm during deposition of the lower Campanian Nenjiang Formation. The upper Yaojia Formation was deposited ... ... hiện toàn bộ

Zircon U–Pb ages and tectonic implications of ‘Early Paleozoic’ granitoids at Yanbian, Jilin Province, northeast ChinaAbstract The Yanbian area is located in the eastern part of the Central Asian Orogenic Belt (CAOB) of China and is characterized by widespread Phanerozoic granitic intrusions. It was previously thought that the Yanbian granitoids were mainly emplaced in the Early Paleozoic (so‐called ‘Caledonian’ granitoids), extending east–west along the northern margin of the Nort...

The Heilongjiang Group: A Jurassic accretionary complex in the Jiamusi Massif at the western Pacific margin of northeastern ChinaAbstract The tectonic setting of the Eastern Asian continental margin in the Jurassic is highly controversial. In the current study, we have selected the Heilongjiang complex located at the western margin of the Jiamusi Massif in northeastern China for geochronological investigation to address this issue. Field and petrographic investigations indicate that the Heilo...

Review of the Pilbara Craton and Fortescue Basin, Western Australia: Crustal evolution providing environments for early lifeAbstract The oldest part of the Pilbara Craton is 3.80–3.55 Ga crust. Between 3.53 and 3.22 Ga, mantle plume activity resulted in eight successive volcanic cycles forming the Pilbara Supergroup. Large volumes of granitic magma were intruded during the same period. By 3.22 Ga, a thick continental crust, the East Pilbara Terrane, had been established. Between 3.22 and... ... hiện toàn bộ

What controls the lateral variation of large earthquake occurrence along the Japan Trench?Abstract The lateral (along trench axis) variation in the mode of large earthquake occurrence near the northern Japan Trench is explained by the variation in surface roughness of the subducting plate. The surface roughness of the ocean bottom near the trench is well correlated with the large‐earthquake occurrence. The region where the ocean bottom is smooth is correl...
