Last glaciation and maximum glaciation in the Qinghai-Xizang (Tibet) Plateau: A controversy to M. Kuhle’s ice sheet hypothesis

Since the late 1950’s, many Chinese scientists have explored the remains of the Quaternary glaciation in the Qinghai-Xizang (Tibet) Plateau and its surrounding mountains. In the main, 3–4 glaciations have been recognized. The largest one occurred in the Late Middle Pleistocene with piedmont glaciers, ice caps and trellis valley glaciers in many high peak regions. But here is no evidence of a unified ice sheet covering the whole plateau as described by M. Kuhle. Due to the further uplifting of the Himalayas and Qinghai-Xizang Plateau the climate became progressively driver, diminishing the extension of glaciers during the Late Pleistocene. The elevation of the snow line during the Last Glaciation was about 4,000 m on the south, east and northeast edges of the plateau and ascended to 5500 m on the hinder northwest of the plateau. The thermal effect of the big plateau massif, the sharp increase of aridity from the southeast rim to the northwest inland area and the abrupt decrease of precipitation during the Ice Age largely account for the distribution of the Quaternary glaciers in the Qinghai-Xizang Plateau. The neglect of Chinese literature may be one of the causes accounting for M. Kuhle’s misinterpretation on the environment of the Quaternary glaciations in the Qinghai-Xizang Plateau.     

A Prospecting Mineralogy Study:Arsenopyrite In Endogenetic Gold Deposits

Arsenopyrite is one of very important and common auriferous minerals in endogenetic gold deposits. In seven gold deposits, the prospecting typomorphic characteristics of arsenopyrite, such as morphological typomorphism, composition typomorphism, pyroelectricity typomorphism and so on, were established. The crystal form of arsenopyrite is simple, and the form symbols mainly are {101}, {120}, {210}, {140}, {230}, {012}, etc. The smaller groin and poor crystal form arsenopyrite indicates the better auriferous characteristics. The major elements (Fe, As and S) of gold- bearing arsenopyrite usually show Fe/As + S ＞ 0.5, As/S＜ 1 which deviates from its theoretical value. The most important trace element is Au and next is Ag in arsenopyrite, and they often show the positive correlation. The pyroelectricity of arsenopyrite can reflect the mineralization epoch, and it also is related to the crystal form and granudarity.     

In the Mountain''''s Shadow: Japan''''s Silk Reelers Blazed an Asian Path of Economic Development

1 Introduction: A Dissonant Fragment On entering Chichibu, many visitors feel as if they were passing through a time warp into another country or a bygone era as the train leaves behind Tokyo抯crowded suburbs and winds through steep slopes forested with oaks, beeches and cedars. The Oku Chichibu highlands, however, are a mere 70 kilometers northwest of Tokyo, or about 50 minutes by rail, less than the average two-hour of daily commute of 搒alarymen?within metropolitan area.

In vitro prebiotic effects of seaweed polysaccharides

Although prebiotic activities of alginate and agar oligosaccharides isolated from seaweeds have been reported, it remains unknown whether seaweed polysaccharides have prebiotic activity. In this study, we isolated polysaccharides from four species of seaweeds, such as Grateloupia fi licina(GFP), Eucheuma spinosum(ESP), Ulva pertusa(UPP), and A scophyllum nodosum(ANP), and characterized their structures and prebiotic ef fects in vitro. The results showed that these polysaccharides were dif ferent in total sugar and sulfate contents as well as monosaccharide composition. GFP and ESP significantly promoted bifi dobacterium proliferation and 0.1% ESP and 0.4% GFP resulted in the highest proliferation rates of beneficial bacteria, whereas UPP and ANP inhibited the growth of beneficial bacteria at all tested concentrations(0.1%–0.5%). The different behaviors of the four seaweed-originated polysaccharides might be refl ected by differences in monosaccharide composition and structure. Therefore, polysaccharides isolated from GFP and ESP could be utilized as prebiotics. However, more studies must be carried out in vivo.     

Overview of In - Situ Biodegradation and Enhancement

Microbial degradation technologies have been developed to restore ground water quality in aquifers polluted by organic contaminants effectively in recent years. However, in course of the degradation, the formation of biofilms in ground water remediation technology can be detrimental to the effectiveness of a ground water remediation project. Several alternatives are available to a remedial design engineer, such as Permeable Reactive Barriers (PRBs) and in -situ bioremediation, Hydrogen Releasing Compounds (HRCs) barrier, Oxygen Releasing Compounds (ORCs) barrier etc. which are efficient and cost- effective technologies. Excessive biomass formation renders a barrier ineffective in degrading the contaminants, Efforts are made to develop kinetics models which accurately determine bio - fouling and bio - filn formation and to control excessive biomass formation.     

Volcanism and Oil & Gas In Northeast China

Based on study on the relation with volcanic rock and oil & gas in Songliao Basin and Liaohe Basin in northeast China, author proposes that material from deep by volcanism enrichs the resources in basins, that heat by volcanism promotes organic matter transforming to oil and gas, that volcanic reservoir is fracture, vesicular, solution pore, intercrystal pore.Lava facies and pyroclastic facies are favourable reservoir. Mesozoic volcanic reservoir is majority of intermediate, acid rock,but Cenozoic volcanic reservoir is majority of basalt. Types of oil and gas pool relating to volcanic rock include volcanic fracture pool, volcanic unconformity pool, volcanic rock - screened pool, volcanic darpe structural pool.

In the Mountain＇s Shadow： Japan＇s Silk Reelers Blazed an Asian Path of Economic Development

Exploring the history of the silk-reeling industry in Chichibu, Japan, this paper challenges the prevalent representation of mountain communities as marginal economic peripheries of the metropolitan center or as reservoirs of poverty and backwardness. Mountain districts were the cradle of an Asian “industrious” revolution that led to Japan‘s modernization. The highland-based silk-reeling producers pioneered an autonomous Asian model of industrial development, which competed successfully against the capital-intensive system introduced from the West into coastal cities. The export strength of silk-producing households in upland villages overturns the claim that Japan‘s economic miracle was based on the introduction of Western technology and administrative systems. To the contrary, the Asian-style management practices and labor standards developed by the silk producers were transferred to a succession of other industries. These indigenous practices account for the rise of Japanese industry in world markets. The clash between the two opposing models of modernization resulted in modern Japan‘s first major civil conflict, the Chichibu Rebellion of 1884, a legacy that has major implications for today‘s recession-mired Japan as well as for developing countries striving for an alternative path to economic development.

杭州雷峰塔遗址地下遥感考古研究

雷峰塔位于杭州西子国宾馆内 ,始建于公元 972年 ,于 192 4年倒塌 ,曾是著名的西湖十景之一--雷峰夕照。为了重现昔日的景观 ,浙江省政府、杭州市政府决定重建雷锋塔 ,为此需要对雷锋塔进行考古清理 ,包括地下部分的清理。为了确定塔基是否存在地宫 ,我们利用雷达设备对该塔基进行了探测 ,明确了地宫的存在。而且 ,地质雷达探测成果资料非常准确 :水平位置 1.0～ 2 .8m,纵向深度 1.3～ 2 .6 m处的雷达波异常反射 ,是由夯土层引起的。水平位置 1.5～ 2 .4 m,纵向深度 2 .6 m处的双曲线型拱起反射波同相轴是地宫顶板 (石板 )引起的。据此亦明确了地宫的大致位置。现场开挖发现地宫大小 (包括地宫周边砖墙 )为 0 .9× 0 .9m,高 0 .5 m,这与雷达图像资料吻合。
