The aim of this study is to shed light on the development characteristics of this type of uranium deposits and provide new clues to further exploration. Detailed study led to the following conclusions: (1) uranium orebodies are hosted mainly in the lower Middle Jurassic Xishanyao Formation and the lower Lower Jurassic Badaowan Formation; (2) the formation of uranium orebodies is closely related to organic matter; (3) the front of the interlayered oxidation zone is snake-shaped in plane and imbricated in the section; the more the interlayered oxidation zone and zonation are developed, the better the uranium mineralization will be; according to lithological and geochemical characteristics, the oxidation zone, the oxidation-reduction transitional zone and the reduction zone can be distin-guished; (4) the development of interlayered oxidation zone is controlled by geological structure, underground water, sandstone permeability and other factors; (5) sandstone uranium orebodies hosted in the interlayered oxidation zone are very complicated in spatial distribution, of which some are rolled and plated in shape and some are highly variable in shape.展开更多
文章在前人研究的基础上,结合藏文文献,对柏林勃兰登堡科学院藏吐鲁番出土的TibHT 107号(T II D 19和T II D 20)梵藏回鹘文多语种《二十一度母礼赞经》文本和版画残片进行了再次研究。结果显示,其中的藏文赞词来源于《甘珠尔》同名经典...文章在前人研究的基础上,结合藏文文献,对柏林勃兰登堡科学院藏吐鲁番出土的TibHT 107号(T II D 19和T II D 20)梵藏回鹘文多语种《二十一度母礼赞经》文本和版画残片进行了再次研究。结果显示,其中的藏文赞词来源于《甘珠尔》同名经典,其中T II D 19号残片中的藏文为第六位度母释梵火天母的赞词,T II D 20号残片中的藏文为第五位度母怛啰吽字母的赞词。吐鲁番版上图下文的版式受到内地唐末以来传统的影响;经与文献比对,版画中度母的造型按日护传规的样式创作而成,绘画风格体现出浓郁的元代宫廷藏传艺术特点;多语种文本和版画综合特征显示,吐鲁番版极有可能来自元朝首都北京或按其刻本仿制而成。该残片为元代多民族文化交融的具体结晶。展开更多
