In the lamented death of Dr.V.K.Ting on January 5th,1936,atthe age of 49,China suffered an irredeemable loss.He may be called thefounder of the science of geology in China,and it was in geological field workthat his contribution was especially great.After his graduation from the Uni-versity of Glasgow he made his way back from Europe to China in 1912 by  相似文献

This book review takes the authors to task for omitting numerous references when they wrote this first comprehensive work on thallium. Among the omissions noted are; 1) the extreme toxicity of thallium; 2) the occurrence of thallium in various minerals:

This book reviewer is quick to point out the many omissions he detected in the Gallium volume. His list includes some 43 citations. Many of these are from foreign journals, but the reader would first have to refer to the Russian source in order to track down the original source. The data cited, however, should be of interest to those seeking geochemical data on gallium. --H. Brown.  相似文献

在川西—滇东地区,前人一直将会理群、昆阳群等作为该区所出露的最古老的地层,并认为它们代表了扬子地台的最老基底。笔者通过对该区详细的变质地质研究认为,在它们之下还存在着一套与之完全不同的层状变质岩系,我们将其称为康定群,推测其时代至少为早元古宙或晚太古宙。它与中、晚元古宙的会理群、昆阳群等共同构成了扬子地台的古老基底,为基底的两个重要的地质构造单元,分别代表了本区早期地壳演化的不同阶段。  相似文献

The reply points out that most of us are inclined to accept ideas if they agree with our own concepts and that we tend to accept them as facts. Kudryavtsev notes occurrences of hydrocarbons in basement rock of the U.S.S.R. which should be of interest to the petroleum geologist and which were unknown to Teodorovich. ‐‐W. D. Lowry.  相似文献

美国基维诺自然铜矿床成矿环境、成矿作用和机制   总被引:1,自引:0,他引:1  
基维诺自然铜矿床生成于陆内裂谷环境。丰富的铜质来自巨厚的裂谷火山岩系(橄榄拉斑玄武岩)。由挤压变形事件产生的断层-裂隙网络为含矿流体向上运移提供了通道。在流体运移过程中,热冷两种流体混合,发生了冷却作用和水岩反应,为低硫的含铜流体沉淀自然铜提供了必需的还原环境。自然铜矿床产出于顶部熔岩流内  相似文献

Little doubt can exist regarding the close affinity between Fusulina (MOLLER) and Schwagerina (MOLLER), though there is much room for discussion as to their genetic relation. The recognized affinity seems to depend rather on their common departure from other members of the family, for  相似文献

本文在介绍一种新的土壤汞量测量找矿方法的同时,着重用大量的实测数据阐明汞在460铀矿床上的分布特征。汞在该矿床上部“黑矿”中的平均含量高达11430ppb,最高达193800ppb,而一般岩石中的汞含量只有数十至数百个ppb。通过对铀矿石及其主岩中的汞的热释谱分析,发现释汞主峰温度在350℃以上的中温、高温相态汞与铀矿化关系密切。铀矿床上部土壤汞晕规模大(550×350m~2),平均含量可达563ppb,最高达6080ppb,平均衬度16,最高达174。汞含量随着采样深度的加深而升高。在矿床外围测出了相似的汞晕,并进行了成矿预测。上述成果已用于生产。  相似文献

喀拉通克铜镍硫化矿区二、三号矿床的两个岩体为隐伏的中-基性岩体,受北西向断裂的控制,侵位于石炭统南明水组上段之下部地层中,为岩浆熔离型铜镍硫化矿床。矿物成分以磁黄铁矿、镍黄铁矿、黄铜矿为主。有用元素除铜、镍外,尚伴生有金、银、铂、色、钴、硫可综合利用。它国内外同类型矿床相比,具有成岩、成矿时代新,岩体基性程度低、铜大于镍等特点,因而又具有新的地质找矿意义。  相似文献
