Magmatic origin of large (up to 5 cm) phenocrysts of K-feldspar is indicated by mineralogical, chemical, and roentgenometric-structural analysis of the crystals. Perthites are found to be metasomatic products of replacement of plagioclase by K-feldspar. This reaction is accompanied by albitization of plagioclase and then by growth of albite after feldspar, in cleavage planes and elsewhere, or by spot-segregations of albite in places formerly occupied by plagioclase. — V.P. Sokoloff  相似文献

全球变化与荒漠化   总被引:17,自引:1,他引:17  
文章以干旱、半干旱地区沙质荒漠化为例,分析了其成因过程、发展趋势。指出干旱是荒漠化的原因,而频繁、过度的人为活动则更加剧其发展。在中国北方荒漠化土地的成因类型中,有30.1%是由于过度放牧,26.9%是由于过度开垦,32.7%是由于过度樵采,有9.6%是由于水资源利用不当,有0.7%是由于工矿交通建设过程中不重视环境保护而造成的。所以合理利用土地和采取相应的防治措施是防治荒漠化的重要途径  相似文献

Neptunian dykes and sills in Jurassic carbonate platform strata of the Betic region of Spain occupy spaces created by wholly mechanical fracturing and displacement of the host strata, and later filled by pelagic sediments from above or by precipitation of calcite from circulating solutions. In some places, joint-bounded blocks of platform carbonates have been wholly removed, possibly by sliding down submarine slopes, leaving a staircase topography, commonly Fe-encrusted, that was subsequently filled by pelagic sediments. Other cavities that formed during Cretaceous times were developed by dissolution and current erosion in moderately deep submarine environments, and then filled by pelagic sediments from above. None of the cavities hosted by either platform or pelagic strata contain evidence for their formation by dissolution in a subaerial environment. The Jurassic and Cretaceous history of subsidence of the Betic margins is thus simpler than in versions requiring repeated emergence to form subaerial karstic cavities.  相似文献

根据旋回特征可把西藏南部的中白垩纪地层分为四个等级。第一级旋回主要是大套的碎屑岩与碳酸盐岩的交替,以及生物种类的变化,表现了当时海平面周期性变化。第二级旋回代表了古生产率和氧化还原的韵律性变化,通过对CaCO3含量的AR-FFT处理得出的周期(ZMa)与Berger等人所计算的理论周期基本相符。因此,可以认为这种旋回根本原因是因轨道参数变化所引起的古环流改变所造成,如地中海型环流与河口型环流的互换,必将导致古生产率以及海洋水体性质的改变。第三级旋回表现为层偶的变化,如泥岩与灰岩互层以及黑色页岩与灰岩互层,在本区主要有三个周期:4.3、5.2和9.2万年,它们分别相当于斜率(ε)和偏心率(C)的理论周期值,旋回的周期主要是因为气候的变化引起陆源物质的稀释作用发生周期性变化,气候的周期性变化是由于轨道参数的改变而引起,因此,这种族回具有全球的可对比性。第四级旋回是由于海水里季节性变化所引起的纹层状层理。  相似文献

对煤矿长斜井盾构机(tunnel boring machine,TBM)施工的风险因素进行了识别,建立了二层次的风险评估指标体系,并确定了风险等级分类标准,利用熵权法确定风险指标的权向量,进而建立了基于集对分析法的煤矿长斜井TBM施工同异反评估模型。在此基础上利用偏联系数的理论确定了文中五元偏联系数的计算方法,根据改进的集对势理论给出风险趋势的预测方法。利用该模型对台格庙矿区煤矿长斜井(1#、2#实验井)TBM施工风险进行了评估与趋势预测。研究表明该模型与方法在煤矿长斜井TBM施工风险分析中是有效的、实用的,可为煤矿长斜井TBM施工风险分析与预测提供一种新的途径。  相似文献

锅穴一定是第四纪冰川的标志吗? *   总被引:9,自引:1,他引:8       下载免费PDF全文
周尚哲 《第四纪研究》2006,26(1):117-125
锅穴地貌现象在西方地学界已有长足的研究,在中国地貌学界也并不陌生。锅穴通常形成于山区溪流河床,也形成于风化风蚀、石灰岩溶蚀、湖滨海岸浪蚀等作用。北美、北欧末次冰期大冰盖覆盖过的地方有冰水形成的锅穴。因此,锅穴是一种多成因的地貌现象。见到锅穴而不加多方辨别论证,一概说成是冰川形成,显然是十分危险的。风化和溶蚀形成锅穴属于物理化学作用,而流水和浪蚀形成锅穴属于水动力作用。关于水动力如何形成锅穴,西方地学界早就形成了公认的解释。冰水锅穴经过反复研究也确认,其形成机理与山区河流无异,均属湍急流水在河床局部形成环流驱动沙砾长期磨蚀的结果。既非西方人19世纪提出的"Moulin Hypothesis"能够成功解释,更非眼下国内少数人倡导的"滴水穿石"能够说明。河谷跌水比想象的冰川终端冰崖缺水更加有利。  相似文献
