The current “mega” interest in Lithium resources was spurred by the development of Lithium-Ion batteries to aid in restructuring the world’s reliance on carbon spewing power petroleum reserves. Current resources of lithium recovery have fallen into two main categories—Pegmatite, found worldwide associated with felsic intrusions and Brine Related, and now with development in the Southwest United States of America (SWUS), a third category— Tertiary Volcanic clays, are specifically associated with Tertiary volcanics and major Tectonic Plate interactions. “Active” Plate tectonics is important as both the SWUS, the Lithium Triangle of South America (LTSA) and the Tibetan Plateau of China (TPC) producing tertiary (Miocene) volcanism that is important to the development of Lithium resources. The Tanzanian part of the East Africa Rift System (EARS) has features of both the SWUS, tertiary volcanic related “playas” and Continental rifting, the LTSA, tertiary volcanic related “Brines” and a major Tectonic plate event (subduction of an Oceanic Plate beneath the Continental South American Plate) and the TPC, tertiary volcanics (?) and major tectonic plate event (subduction of the Indian Continental Plate under the Eurasian Continental Plate). As well as the association of peralkaline and metaluminous felsic volcanics with Lithium playas of the SWUS and the EARS (Tanzania) “playas”. These similarities led to an analysis of a volcanic rock in Northeast Tanzania. When it returned 1.76% Lithium, a one-kilometer spaced soil sampling program returned, in consecutive samples over 0.20% Lithium (several samples over 1.0% lithium and a high of 2.24% lithium). It is proposed that these four regions with very similar past and present geologic characteristics, occur nowhere else in the world. That three of them have produced Lithium operations and two of them have identified resources of Lithium clay and “highly” anomalous Lithium clays should be regarded as more than “coincidental”. 展开更多

西南非海岸盆地位于南大西洋的非洲海岸地区,由上侏罗-下白垩统裂谷盆地和上白垩-全新统被动陆缘盆地叠合形成,是一个热点油气勘探区。在调研国外油气地质研究的基础上,根据地震、测井资料,详细描述了西南非海岸盆地在中生代的构造形态... 西南非海岸盆地位于南大西洋的非洲海岸地区,由上侏罗-下白垩统裂谷盆地和上白垩-全新统被动陆缘盆地叠合形成,是一个热点油气勘探区。在调研国外油气地质研究的基础上,根据地震、测井资料,详细描述了西南非海岸盆地在中生代的构造形态与沉积充填特征,明确了其纵向演化与横向迁移规律,并依据已知油气田的钻井与测试资料,综合分析了盆地油气富集的基本地质条件。研究表明,西南非海岸盆地始形成于侏罗纪晚期,早期以剧烈的断裂与火山活动为特点,裂谷盆地内部填充大量砂岩和页岩;在经历白垩纪巴雷姆期与阿普特期的过渡阶段后,于阿尔布期进入被动陆缘阶段,在过渡与被动陆缘阶段,盆地内部以细粒海相沉积为主,可见少量碳酸盐岩与盐岩。盆地阿普特阶主力烃源岩与其上覆的上白垩统碎屑岩储层共同组成了油气成藏组合。 展开更多

FOLLOWERS of Buddhism. the Dai ethnic community lives mostly in Xishuangbanna and other areas of Yunnan Province in southwest China. The Dai language has its own script but uses the Hart Chinese script as well. Rice is their staple food. Some Dais prefer glutinous rice, which is put inside a bamboo tube and gently roasted to make the popular Bamboo Rice - a rice dish with a delicious bamboo flavor, The Dais like spicy and sour flavors and pickled meat and fish are some of the popular dishes. 展开更多

This paper seeks to overcome the split between discourse-based and economic/materialist approaches to the explanation of colonialism.The author tracks the formation of"native policy" which was at the core of modern colonial rule,in the German colonies of Samoa,Qingdao/Jiaozhou,and Southwest Africa.Economic forces and international military aims do not explain the variation among the very different native policies that emerge in these colonies.Their true determinants are a combination of three factors: precolonial racial/ethnographic discourse;colonial officials’ competition with one another through claims of superior ethnographic knowledge;and the degree and nature of colonizers’ imaginative identification with images of the colonized(Sinophilia, for example).Economic interests shaped the annexation of some colonies,such as Southwest Africa,and geopolitical interests shaped the German decision to retreat from a colonial stance vis-à-vis China and to engage in a less direct politics of"cultural imperialism" in the years leading up to World War One.The effects of economic interests on the ongoing production of colonial native policy are always mediated by the details of European ethnographic representations. 展开更多
