Geochemical Composition of Beach Sands from Tottori Prefecture, Japan
島根大学地球資源環境学研究報告 30, 65~72 ページ(2011 年 12 月) Geoscience Rept. Shimane Univ., 30, p.65~72(2011) Article Geochemical composition of beach sands from Tottori Prefecture, Japan Bah Mamadou Lamine Malick*, Erika Sano* and Hiroaki Ishiga* Abstract Fifteen sand samples were collected from ten beaches along the shoreline of Tottori Prefecture to determine their geochemical compositions, using X-ray fluorescence analysis. Two main river systems (Tenjin and Sendai Rivers) supply sediments to the shoreline from the Chūgoku Mountains. Beach parameters, such as the radius of the approximated circle and radian (ℓ/r), were used to describe beach forms: ℓ/R < 1 describes a short and concave pocket beach. Sands from the eight beaches investigated in the area contained more than 70 wt% SiO2, and are predominantly composed of quartz and feldspar. This was reflected in their geochemical compositions, with significant SiO2, Al2O3 and Na2O contents of the beach sand samples further indicating that quartz and feldspar are the main constituents. Detritus was derived from quartz-rich sources, and quartz dilution strongly influences the bulk chemistry of the beach sands. Positive correlation of most elements with Al2O3 and negative correlation with SiO2 suggests quartz dilution is the main control on chemistry. The sediments were derived from relatively felsic source rocks. Key words: Chūgoku Mountains, Tottori Prefecture, beach sand, geochemistry, quartz, feldspar area is thus needed. Introduction The purpose of this study is to describe the geochemical The compositions of coastal sediments are influenced by compositions of fifteen beach sand samples collected from numerous components and processes, including source ten sites along the shoreline of Tottori Prefecture in the area composition, sorting, climate, relief, long shore drift, and where the Sendai and Tenjin Rivers supply sediments. -

Practical keys to the Japanese 43 genera and 122 species are provided including this new species. A check list and data of specimens examined are also provided. Key words: Diptera, flesh flies, new species, new genus, Sarcophagidae, Japan INTRODUCTION The collection of Sarcophagidae made by the first author was studied during the course of the taxonomical studies on the calypterate muscoid flies from Japan since 1970 (Kurahashi, 1970). This was a revision of the subfamily Miltogramatinae dealing with seven genera and 14 species. Before this, Takano (1950) recorded seven genera and nine species of Japanese Sarcophagidae. Many investigation on the Japanese flesh flies made by Drs. K. Hori, R. Kano and S. Shinonaga beside the present authors. The results of these authors were published in the part of Sacophagidae, Fauna Japanica (Insecta: Diptera) and treated 23 genera and 65 species of the subfamilies of Sarcophaginae and Agriinae (=Paramacronychiinae), but the subfamily Miltogrammatinae was not included (Kano et al., 1967). -

Distributions of a Halophilous and a Riparian Species of Harvestmen Along Sendai River, Tottori City, with the First Records of Harvestmen in Tottori Sand Dunes

Psathyropus tenuipes was found from the mouth of the river to the site 4 km upstream where slight salinity (0.1 PPT) was detected in the river. On the other hand, no specimens were found from the upstream sites where no salinity was detect- ed. This indicates that the species needs at least a slight salinity for its occurrence. Paraumbogrella pumilio was found at five sites from the dry riverbed near the Shobu floodgate to a site on the right bank of Sendai River just upstream of Yachiyo Bridge. Occurrence of this species seems to be related to presence of open ground covered with lower grasses on the banks. Recently, the both species were also found from the right bank of the river mouth of Sendai River that is also a part of Tottori Sand Dunes. -
Japan in Winter – Winter Birding at Its Best 2016 Trip Report
Trip Report for Japan in Winter for Photographers Dates : 20th February - 5th March 2016 Guide: Jun Matsui Day 1 – Saturday 20th February : Day 2 Arrival day. Everyone met for dinner in the hotel- Sunday 21st February: Narita - Izumi Nature Park - Nagakura Shrine, Karuizawa Notable sightings, Brown-headed Thrush, Northern Goshawk, Black- crowned Night Heron, Mandarin Duck. We started the days birding at a small creek near the hotel This was the only place we saw Brown-headed Thrush for this trip. We also saw Japanese Tit, Meadow Bunting and other common species as well. It provided a nice introduction to Japanese birds. Then we headed off up to Karuizawa. Since I surprisingly, didn’t have a good view of the extremely photogenic Mandarin Duck on the previous winter tour, we side tracked to Izumi Nature Park, where Mandarin Duck relatively common to make sure of them. We had good views of them there. DayMandarin ducks at Izumi 2 - Monday 22nd February: Bird Forest - Shiotsubo Onsen Hotel - Saku Reservoir Notable sightings, Japanese Woodpecker, Varied Tit, Smew, Fox. Bird around Bird Forest, Karuizawa. It was rather quiet in the forest and there was not much bird activities so we retired to the Shiatsubo Hotel lounge where we spent a nice time overlooking the bird feeder. We had great looks at a variety of tits and buntings. After lunch we visited Saku reservoir, the numbers of waterfowl were not great , but there was still a nice variety of species, more Daythan enough to keep us busy and interested 3 - Tuesday 23rd February: .

In recent infrastructure development, it is required to further utilize existing stocks, and many projects of the upgrading dam are implemented and planned in the water control and water utilization. IHI Infrastructure Systems Co., Ltd. has also participated in several upgrading dam projects and introduces previous experiences from the standpoint peculiar to upgrading dams in order to make reference to similar projects in the future. 1. Introduction of flood control and water utilization (power generation) in 1959. Japan is currently facing the need to make effective use of The riparian release conduit installed in this project was existing stocks while reducing total cost for infrastructure designed to eliminate cold water release and prevent the development, and endeavors to respond to this need is being prolongation of turbid water release, as well as to suppress made nationwide. From this perspective, it is thought that the eutrophication of reservoirs. efforts to utilize existing dams for a prolonged period of time This conduit is connected to selective water withdrawal in an effective and sustained manner are important for equipment that was separately installed (beyond the scope of addressing challenges in water control and utilization; and this project) on an intake conduit, enabling water to be various approaches, including flexible management, upgrading released at a rate of up to 10 m3/s at the lowest water level dam heights, and construction of tunnel spillways, are being after dam improvement. -

Okinoshima Island and Related Sites in the Munakata Region”
“Okinoshima Island and Related Sites in the Munakata Region” Study Report II / 1 English Translation 2012 World Heritage Promotion Committee of “Okinoshima Island and Related Sites in the Munakata Region” Foreword “Okinoshima Island and Related Sites in the Munakata Region” are our heritage consisting of Okinoshima Island, where state-related rituals were held from the late 4th century to the end of the 9th century, Munakata Taisha, a Shinto shrine that developed from the rituals on Okinoshima Island, and a group of mounded tombs associated with the Munakata clan and maritime people who undertook the rituals. Worship of Okinoshima Island and rituals at Munakata Taisha have been protected and passed down by local people of the Munakata region from ancient times to the present. The group of mounded tombs also remains in a good state of conservation, giving testimony to the characteristics of the place and people at that time. While we can learn many things from this property, we have the responsibility to pass down the value of this precious property to future generations. It was in this recognition that the World Heritage Promotion Committee of “Okinoshima Island and Related Sites in the Munakata Region” was set up in January 2009 to pursue World Heritage List inscription as a means to protect and pass down the value of this property. In order to achieve World Heritage List inscription, it is necessary to define the Outstanding Universal Value of the property. A study project started in order to verify the value of this property and Study Report I was published in the fiscal year 2010.
