Conodont Caudicriodus woschimidti woschmidti has been found from a big outcrop (hill) of the Bayan-Kho-shuu Ruins Section which was previously assigned to the Silurian Gavuu Member of the Mandalovoo Formation. This is first time to find the lowermost Devonian conodont zonal fossil in Mongolia. The lower part of the Gavuu Member is Sil-urian. But the strata from where we collected samples M-9～M-12 definitely belong to Lower Devonian (lower Lochko-vian) rather than Lower Silurian. The Mandalovoo Formation should be named Mandalovoo Group, and its three mem-bers should be changed into three formations.

＜正＞This paper discusses the ever-increasing problems of impoundment at Yakutsk related to anthropogenic disturbance of the natural drainage of suprapermafrost *** main factors that complicate effective control of impoundment and flooding are indicated,including the unsuitability of conventional drainage systems,impeded suprapermafrost runoff,suprapermafrost water formation in the so-called"cultural layer",and icings from leaking pipes.A combined drainage system consisting of main,street and local drain pipes is proposed to protect the urban area from suprapermafrost water *** tanks are recommended to provide gradients necessary to maintain continuous water flow in the drainage system.

The Awulale metallogenic belt(AMB)of the western Tianshan(NW China)includes Late Carboniferous(ca.320 Ma)ore-bearing volcanic rocks of the Dahalajunshan *** petrogenesis and tectonic setting of these volcanic rocks are important for the understanding of the tectonic evolution and metallogeny of the western *** paper presents new major and trace elements and Sr-Nd-Pb isotope data from the Dahalajunshan volcanic rocks,which are mainly calc-alkaline basaltic trachy-andesite and trachy-andesite with subordinate basalt,trachy-basalt and *** variations of major and trace elements in the mafic and intermediate volcanic rocks indicate the fractionation of pyroxene and magnetite or hornblende,magnetite,apatite and plagioclase,respectively,during their *** Dahalajunshan volcanic rocks have similar primitive mantle-normalized diagrams and chondrite-normalized rare-earth element(REE)patterns suggesting their similar mantle source(s).They are characterized by enrichment in large ion lithophile elements(LILEs)and light REEs(LREEs),depletion in heavy REEs(La/Yb≈2.80 to 9.59)and high field strength elements(HFSEs)andε(t)ranging from+1.2 to+6.0 atSr/Sr(t))=0.7047-0.7063 andPb/Pb=*** the geochemical and isotopic data indicate that the volcanic rocks were probably derived by low-degree melting of sub-arc lithospheric mantle modified by fluids in a continental arc *** obtained results,in conjunction with previous published data,allow us to suggest that the southward subduction of Junggar oceanic crust continued until the Late Carboniferous and was followed by a tectonic shift from continental arc to post-collisional extension environment.

The Baikal Group is one of the most important stratigraphic units in the geology of East Siberia (Upper Riphean). This paper focuses on litological-facies features based on the analysis of organic remains (stromatolites, microphitolites and microfossils), in order to better precise the age and environmental deposit conditions of the Baikal Group. The results are used to draw a correlation between all the Precambrian of deposits of the South of East Siberia. The stratigraphy of the Baikal Group is then compared to the geodynamic evolution of this region, characterized by the break-up of the supercontinent Rodinia and subsequent opening of the Paleo-Asian Ocean. Stratigraphic analogs to the Baikal Group display in most areas deposits of various minerals (complex ores, phosphoresces, bauxites etc. have been dated of the same age), so the present study would also provides an economic interest.

The paper presents research data on positive and negative coronas inatmospheric pressure air in a highly inhomogeneous electric field. Thedata show that irrespective of the polarity of pointed electrodes placed ina high electric field (200 kV/cm), this type of discharge develops via ballstreamers even if the gap voltage rises slowly (0.2 kV/ms). The start voltageof first positive streamers, compared to negative ones, is higher andthe amplitude and the frequency of their current pulses are much lower:about two times and more than two orders of magnitude, *** higher frequency of current pulses from negative streamers provideshigher average currents and larger luminous areas of negative coronascompared to positive ones. Positive and negative cylindrical streamersfrom a pointed to a plane electrode are detected and successive dischargetransitions at both polarities are identified.

Using data samples collected at center-of-mass energies of √s=4.009, 4.230, 4.260, and 4.360 GeV with the BES0 detector operating at the BEPC/ collider, we perform a search for the process e＋e-→γχc,j （J =0, 1, 2） and find evidence for e＋e-→γχc1 and e＋e-→γχc2 with statistical significances of 3.0σ and 3.4σ, respectively. The Born cross sections σB（e＋e-→γχc,j）, as well as their upper limits at the 90% con dence level （C.L.） are determined at each center-of-mass energy.
