Stratigraphy and geological structure of the Paleozoic system around Ulaanbaatar, Mongolia
vol.28, p. 1-18. » 要旨を表示PDF（10.4MB）
DOI: 10.18999/bulnum.028.01Recent mapping study in the Ulaanbaatar area has revealed that the geology around Ulaanbaatar previously reported should be revised in regard to stratigraphy and geological structure. Here, the new division of strata and geological structure are presented.
Detailed field mapping with careful observation of sedimentary structures such as grading, loadcast, cross lamination, channel structure, and so on which indicate stratigraphic top have been carried out. The results show that many parts of strata were overturned and the geological structure is characterized with overturned folds with south vergence. In particular, the Paleozoic system is newly divided into two accretionary complexes (Altan-Ovoo & Orgioch-Uul Formation and Gorkhi Formation) and a shallow marine formation. Most of the previous shallow marine Carboniferous system is replaced by the two accretionary complexes and the shallow marine Carboniferous system which occurs with fossils indicating shallow sea environment only distributed in narrow area between two faults, although the latter has been regarded as extensively distributed around Ulaanbaatar. The geology suggests that the shallow marine sediments overlie the accretionary complex (Altan-Ovoo & Orgioch-Uul Formation), unconformably.
The accretionary complexes are classified with quite different from the stratigraphy observed in clastic rocks. The Gorkhi Formation is composed of chert, siliceous shale and clastic rocks dominating massive and thick-bedded sandstone in ascending order. The Altan-Ovoo & Orgioch-Uul Formation consists of basalt, chert, siliceous shale and clastic rocks dominating thick- to thin-bedded sandstone and mudstone in ascending order.
Furthermore, it is found out that the previous Gorkhi Formation in the northwest area and the previous Carboniferous system in the central south area are regarded as weakly metamorphosed and strongly deformed equivalents to the Altan-Ovoo & Orgioch-Uul Formation. Geological structure of these strata represents south vergence such as north-dipping thrust and fold-axial plane. The fact strongly suggests that north-directing subduction formed these geological structures. - Yuki Nakane, Toshiyuki Kurihara, Bakhat Nuramkhaan,

Geological division of the rocks at southeast of Ulaanbaatar (Gachuurt-Nalaikh), central Mongolia
vol.28, p. 19-26. » 要旨を表示PDF（3.93MB）
DOI: 10.18999/bulnum.028.02This paper describes lithology and radiolarian fossils from a chert slab in the Gachuurt-Nalaikh area, southeast of Ulaanbaatar, central Mongolia, and discusses the geological division of the rocks in this area.
The rocks in this area consist of clastic rocks with chert slab intercalations. Although the rocks of this area have been previously divided into the Gorkhi, Altan-Ovoo, and Orgioch-Uul Formations, there are no significant structural and lithological gaps across the boundaries between these formations. Therefore, there is no reason to divide the rocks of this area into the three formations, and these three formations should be regarded as a single geological unit.
A conformable succession of Devonian radiolarian chert, siliceous shale, mudstone and sandstone in ascending order, which is generally regarded as ocean plate stratigraphy (OPS), were found from this area. The repetition of chert and clastic rocks with OPS within this area might show the stacking of tectonic slices of the chert-clastic rock sequence within an accretionary complex. This suggests that the rocks of this area should be regarded as the northern extension of the Gorkhi Formation of an accretionary complex, though most of the rocks of this area have been previously assigned to Carboniferous shallow marine system. - Toshiya Suzuki, Yuki Nakane, Bakhat Nuramkhaan,

Description of sandstones in the Ulaanbaatar area, Mongolia.
vol.28, p. 27-38. » 要旨を表示PDF（3.81MB）
DOI: 10.18999/bulnum.028.03The texture and the grain composition of sandstone provide information about the tectonic setting of basins of deposition and associated provenances. The geological history of the Khangay-Khentey belt composed of pre-Carboniferous accretionary complex and Carboniferous shallow-marine strata was linked with the evolution of the Mongol-Okhotsk Ocean. This paper describes the sandstones of the Gorkhi, Altan-Ovoo & Orgioch- Uul Formations and Carboniferous shallow marine system, that occurs around Ulaanbaatar city.
The sandstones in the Gorkhi and Altan-Ovoo & Orgioch-Uul Formations are classified as feldspathic arenite. They are clast supported and poorly-sorted, with dominantly angular to very angular grains mainly composed of quartz, potassium feldspar, plagioclase and rock fragments of rhyolite and tuff. The modal framework grain analysis shows that sandy detritus was derived from “continental crust” where erosion has cut deep into volcanic cover. The sandstone in the Carboniferous shallow marine system classified as feldspathic wacke is rich in muddy matrix and poorly-sorted, dominantly includes rounded to little angular grains of quartz, potassium feldspar, plagioclase and rock fragments of rhyolite, felsic tuff, andesite and basalt. The Qm-F-Lt diagram suggests that the sandstone is originated from the “transitional arc”.
The sandstones from the Gorkhi and Altan-Ovoo & Orgioch-Uul Formations are significantly similar and they can not be distinguished to each other in their textures, grain compositions and poor in rock fragments, and they were originated from the same kinds of source, i.e. continental crust where erosion has cut deep into volcanic cover which related to the subduction of oceanic plate. However, the lithostratigraphies of these formations are quite different each other and they were likely to have been formed at different places, or formed in different ages each other. The volcanism evidenced by the felsic tuff intercalations in the Altan-Ovoo & Orgioch-Uul Formation at the provenance area was likely enough immature which could not provide much volcanic rock fragments to the basin. The sandstone of the “Carboniferous formation,” rich in volcanic rock fragments, strongly indicates that the volcanic activity had developed to supply volcanic rock fragments into the sedimentary basin of this formation. - Bakhat Nuramkhaan, Yuki Nakane, Shoko Yamasaki,

Description of a NW-trending brittle shear zone, Ulaanbaatar, Mongolia
vol.28, p. 39-43. » 要旨を表示PDF（3.61MB）
DOI: 10.18999/bulnum.028.04A fault trending NW-SE from central Ulaanbaatar to Nalaikh, Mongolia, has been inferred from a topographical viewpoint, however, its lithological and kinematical characteristics remain uncertain. This paper describes the lithology and kinematics of this fault. The rocks of the Gorkhi Formation are intensely fractured to form a brittle shear zone sub-parallel to the topographical lineament from central Ulaanbaatar to Nalaikh. The fractured rocks are partly foliated with vertical planes striking N 15°to 30°W. The shear zone extends for ca. 40 km north from Nalaikh. Dragging fold and P-Y fabric of the fractured rocks show top-to-the south sense of shear.

Origin of the Early Mesozoic Bogd Uul granite pluton, Ulaanbaatar area, Mongolia
Title
vol.28, p. 45-59. » 要旨を表示PDF（5.63MB）
DOI: 10.18999/bulnum.028.05We present new isotopic age and geochemical data of the Bogd Uul granite pluton occurred in the margin of Khentey uplift, in the Ulaanbaatar area. The Bogd Uul granite pluton consists of slightly peraluminous, high-K, calc-alkaline series biotite and hornblende-biotite granite of A2-type. The Rb-Sr isochron age of the Bogd Uul granite pluton in this study confirm our former determined early Mesozoic age of the single zircon lead evaporation, and U-Pb isotopic analyses using a Laser Ablation Inductively Coupled Plasma Mass Spectrometer (LA-ICP-MS). The Bogd Uul granite pluton is formed in post-collisional environment, and granitic magma derived from continental crust contaminated with juvenile mantle-derived component due to geochemical analyses and Rb-Sr isotopic data which show the initial 87Sr/86Sr=0.7005-0.7030, εNd(T)=(+0.7)- (+1.4), model ages of 826-1077 Ma. The topological analyses of zircon in the Bogd Uul granite pluton confirm the mixed sources which determined isotopic and geochemical data.

Siliceous shale and Radiolarian fossils of the Mazegawa Formation
vol.28, p. 61-75. » 要旨を表示PDF（1.73MB）
DOI: 10.18999/bulnum.028.06The occurrence of Jurassic radiolarian fossils in the Hida-Kanayama area was first reported in 1979 by an undergraduate student (Mr. Masao Sakai) of Nagoya University. Sakai’s report was new information on the geology of the Mino Terrane, and gave us motivation for re-study of the area from the micropaleontological standpoint.
At Hid-Kanayama, we started to detailed mapping and sampling of the Radiolaria-bearing rocks; and I asked Dr. Ken Shibata (Geologicl Survey of Japan) to carry out the isotope agedetermination for the rocks in the Hida-Kanayama area. We reported our study results in the meeting of the Paleontological Society of Japan held at Nagoya University on Oct. 20, 1979 (Mizutani, Okamura and Shibata, 1979). We also started to re-study throughout the Mino Terrane from a new viewpoint. Surprisingly enough, staffs and graduate students found siliceous shale in many areas in the region which contains the Jurassic radiolarians ranging in age from Bathonian to Tithonian. I reported orally the result of our studies to Dr. Teiichi Kobayashi, Emeritus Professor of Tokyo University, and he strongly recommended me to publish it on the Proceeding of Japan Academy (Mizutani et al., 1981). I also described my own study result and publisehed it on the Bulletin of the Mizunami Fossil Museum (Mizutani, 1981).
Petrographic researches of these sedimentary rocks were carried out, particularly concerning the origin of chert or siliceous materials. It seemed to me that the fundamental problem lies in the origin of silica and the process of crystallization from amorphous silica to quartz in chert or siliceous shale. I did an experimental research on transformation of amorphous silica to quartz under the hydrothermal conditions. I found that the transformation process from amorphous silica to cristobalite and then to quartz could be reasonably expressed by differential equations, when we introduced the induction period for the reactions. I have not yet done, however, any discussions on the essensial meaning of this induction period.
In the present paper, I will examine many kinetic reactions in which the reactions are related with the induction period. It seems to me that amorphous silica, i.e. nano-sized particle necessitates the induction period when it is transformed to another phase.
After my own work on the Mazegawa Formation in 1981, Wakita (1987) studied the same area in detail, and found that the younger radiolarian assemblage from Tithonian to Berriasian, composed of Pseudodictyomitra carpatica (Lozyniak) and Ditrabs sansalvadorensis (Pessagno) of the “Pc assemblage” in the Mino Terrane. He extended his field work to the entire part of the Mino Terrane (Wakita, 1988a, 1988b).
He thought that his idea would be applied in other places, and carried out a research work on the tectonic evolution of South and Southeast Asia. His idea was persuasively applied to that region like the Mino Terrane in Japan (Wakita et al., 1997; Wakita and Metcalfe, 2005). The latest volume of Tectonophysics (vol.568-569) was planned to publish a special issue on mélange with various examples from active tectonic belts in the world. Wakita (2012) also presented his paper and discussed the mélange formation in the Mino and the Chichibu Terranes from SW Japan. This Tectonophysics was published in color; all the maps and figures in each paper on the complex and complicated mélange provide useful information for us. - 大場 裕一（OBA Yuichi）

Radiolarian Fossils Mentioned in YOSHIDA Otohiko (1900)
vol.28, p. 89-94. » 要旨を表示PDF（1.97MB）
DOI: 10.18999/bulnum.028.09In June 1900, YOSHIDA Otohiko submitted his dissertation thesis of the title “Report on Geology of the Southern Part of Higo” to the Department of Geology in the University of Tokyo. He discovered well-preserved radiolarian fossils in siliceous slates near Ohira village of Itsukimura, identified them as Cenosphaera gregaria (?); Lithocampe aptycalphila (?); Spongodiscidae sp.; Rhopalastrum sp.; and Sphaerozoum sp.; and depicted their fairly detailed figures. YOSHIDA considered the radiolarian fossils to be Palaeozoic, because the radiolarian slates were accompanied with Fusulina-bearing Palaeozoic limestones.

DOI: 10.18999/bulnum.028.10Collared Scopos Owl is migratory and eastern Asian endemic nocturnal raptor species. The species was listed on the Red Data Book of Aichi (2009 version) and Nagoya (2010 version) as near-threatened category. In Nagoya, some individuals are observed mainly in migratory seasons and others in winter. I reported banding record of the species in the winter season of 2011 in Nagoya University Higashiyama Campus. This capture record was the third one in Nagoya to date. The plumage indicated that the individual coulf be first-winter age but the sex was unknown. I also summarized winter observation and collected records in Nagoya.
