简介：微隧道通常在0.3nm的范围与孔指矿物质的结构的隧道到2.0跑。如此的微隧道包括，K在cryptomelane充满的Mn-O八面体隧道，和Si-O和Al-0四角形的分子的筛构造的隧道在沸石由Na和Ca充满了，并且有效地有分子的筛的功能。这里，我们指出自然矿物质的ultra-microchannels与离子的筛的特征在0.3nm下面有孔。矿物质长石的ultra-microchannels，为地球的半团的财务“scrust，因为孔是太小的，大部分被忽略了。在这个工作，我们在场那长石显示离子交换的某个度并且在高、低的温度下面拥有隧道结构的一个特征。在高温度，Na~+能进入长石的隧道。在直到15.9%的长石增加的Na_-O的Thecontent。在中间的温度，Pb~(2+)能也作为离子交换的结果进入长石的隧道，这样带到形成ofPb长石。在房间温度，大约97.94%Cd~(2+)能被移开，Cd长石能被获得。这些现象显示长石的ultra-microchannels的典型效果，它可以为重金属污染和原子废物的处理作为一个潜力被建议。自然矿物质的Theultra-microchannels在移植和交换ofgeomaterials起了特殊作用。一些自然矿物质的微隧道的分子的筛有净化分子的煤气的污染的性质。并且很自然的矿物质的ultra-microchannels的离子的筛能净化离子的水污染。

简介：摘要：广泛有机物(OM)富有的外形(黑页岩)在Yangtze区域发生在Ordo志留纪边界继任，华南。为了在Ordo志留纪期间调查Yangtze海的氧化还原作用变化，转移，二OM节(在在Zhangjiajie的Yichang，湖北省，和Sanjiaguan的Wangjiawan，湖南省)跨骑Ordo志留纪边界被学习。在这研究完成的大小包括总数的内容Fe的器官的碳(TOC)，黄铁矿硫，和不同种类，包括dithionite可引出的Fe(喂)，黄铁矿Fe(FeP)，HCI可引出的Fe(FeH)，和全部的Fe(FeT)在黑页岩，象另外的氧化还原作用代理一样，例如S/C比率，在高度反应的Fe之间的比率(FeHR=喂了+FeP)并且FeT，和Fep/(FeP+FeH)比率，作为pyritization(DOP)的度知道。在Wangjiawan节，中间的Ashgill沉积有高FeHR/FeT比率(0.20-0.77；avg。0.45)，高DOP价值(0.21-0.72；avg。0.54)，并且器官的碳内容的一个相对经常的硫内容独立人士。由对比，中间早，Hirnantian存款通常有低FeHR/FeT比率(0.10-0.35；avg。0.21)，低DOP价值(0.11-0.40；avg。0.28)，并且S/C价值在正常海洋的价值上正在聚类(S/C=0.36)。迟了的Hirnantian和早Rhuddanian存款，类似于那些中间的Ashgill存款，被高FeHR/FeT比率描绘(0.32-0.49；avg。0.41)，高DOP价值(0.46-0.68；avg。0.53)并且相当经常的硫内容。这些数据在间隔期间在Yangtze海架上建议海洋的血缺氧的出现中间的Ashgill，迟了的Hirnantian和早Rhuddanian，和通气并且氧化的水兵调节在期间中间早Hirnantian时间。中间早，Hirnantian通气了事件是有全球冰川的经期的伴随物，多半在架海床之上源于glacio海面升降的海平面的秋天和冷、稠密的氧化的水的随后的循环。因此，突然的变化从从迟了的Hirnantian氧化了到缺氧的海洋的水，早Rhuddanian从海面升降的海水平的冰期后的上升被结果。在subemergent高地附
