湖南省核电厂侯选厂址的工程地质评价

１９９２年以来，湖南省电力勘测设计院在省内开展了核电普查选址工作，经过３年多的勘查，现已筛选出４个侯选厂址。作者著文探讨了这４个厂址的地震地质特征和工程地质条件，可供进一步选址参考     

Petrology and Petrogenesis of the Eclogite in Mt.Dabie Area,Central China

The occurrence,mineralogy and geochemistry of eclogites in the Mt.Dabie area show that they were subjected to a high-pressure metamorphism together with the country rocks,but their petrochemistry and REE geochemistry show some difference from those of the country rocks.The geochemical characteristics of the eclogites are similar to those of bot continental tholeiitic basalt and oceanic tholeiitic basalt.The rocks probably subducted to the upper mantle with the Dabie metamorphic complex.When elevated to the surface,they were subjected to different staes of retrogressive metamorphism.     

鄂尔多斯盆地夜暴雨多

该文用鄂尔多斯盆地及周围干旱、半干旱及沙漠地区３４个气象台站３７－４４年夜暴雨资料进行了研究，分析了鄂尔多斯盆地及周围地区暴雨的昼夜分布，给出了暴雨昼夜强度极值，重点讨论了地形对夜暴雨的作用。     

北山泥盆纪碰撞造山火山－磨拉石地质构造及地球化学特征

本区早泥盆世旱山微大陆与塔里木板块的北山地体间发生对接，原洋区变为残留滨浅海区。中泥盆世该区形成中央断块山，相应南带的断陷山间洼地内形成陆相磨拉石堆积，北带与南蒙古洋毗邻，形成陆缘滨浅海火山－磨拉石沉积。经计算，中带造山隆起侵蚀速率为０．１５４ｍｍ／ａ。晚泥盆世火山岩显示弱碱性和深熔岩浆喷溢特点，表明陆壳演化尚未达到完全稳定的阶段。     

CO_2快速检测管用于普查金、铀矿的初步试验

本文叙述了CO_2快速检测管(简称CO_2速测管)的原理、野外观测方法、地质效果以及在测量中应注意的问题。野外试验结果表明:在已知金、铀矿床上测到了明显的CO_2异常。     

绿岩套和蛇绿岩套的区分标志

综合绿岩、蛇绿岩的有关概念、地质环境、岩石学、地球化学特征,论述蛇绿岩和绿岩之间的异同。 目前由于太古宙和显生宙地质构造研究的进展,使人们对绿岩套和蛇绿岩套的特征及其相互之间的异同性、联系性和形成环境越来越感兴趣。同时,在不同地区的地质构造研究中,对上述两种岩套在概念上和成因上存在混淆。本文将讨论这一问题。     

兰州台倾斜固体潮初步观测结果

1.台址及仪器状况兰州台是甘肃省唯一的(Ⅰ类)形变综合观测台,架设有国家地震局地震研究所研制的目前国内最先进的FSQ型自记水管倾斜仪。该台位于(L=103°.7520,λ=36°.0980,H=1550米)兰州市安宁区人防山洞内,洞体进深145米,岩层直立,覆盖层厚29—88米。为了     

Characteristics of geomagnetic storm spectra in middle and low latitude regions and their relation with the tangshan earthquake

The characteristics of 80 geomagnetic storm spectra have been analyzed and compared for the records at seven observatories: Beijing, Qingguang, Changli, Guangzhou, Sheshan, Wuchang and Changchun during 1973–1977. The general natures of the spectra are thus obtained. The results are as follows. First, there are synchronous trends of change in the magnetic storm spectral amplitude at the seven observatories. Second, the sepctral slopes of all the magnetic storms are almost the same. The yearly average values of the spectral slopeb are quite steady within the period range from 0.5 to 6.8 hours. This means that the magnetic storms have the same energy partitioning factor. Third, there are significant changes in the yearly average values of spectral interceptsa for the three observatories of Beijing, Qingguang and Changli which are near the Tangshan earthquake area, but the values are quite steady for the four observatories of Guangzhou, Sheshan, Wuchang and Changchun which are far from the earthquake area. It seems that the noticeable changes are related to the great Tangshan earthquake of July 28, 1976.
