石油地质领域中的核技术

本文论述了利用一整套非常规核和地球物理方法来解决石油和天然气地质领域中的一些理论和实际问题的可能性，这些方法包括：天然辐射的α粒子和γ能谱测量、仪器中子活化分析和裂变辐射照相技术。本文对每种方法都作了简单的阐述。     

广西老厂铅锌矿床地质特征及其成因探讨

本文是在专题研究基础上,探讨广西老厂铅锌矿床地质特征和矿床成因。该矿床位于海洋山复式背斜南段的老厂穹窿构造核部,铅锌矿化受构造、地层和岩性控制。矿体呈脉状,产于NE向组张扭性断裂构造中;围岩为寒武系白云岩,板岩、砂岩;矿石类型以锌为主,矿物成分简单,以闪锌矿、方铅矿与石英、白云石为主,具充填、交代矿石结构、构造,矿石平均品位含Zn9.94%、Pb1.50%;围岩蚀变主要为硅化、绢云母化和碳酸盐化。据地层岩石元素丰度值、稀土元素配分和稳定同位素数据、资料,探讨了成矿物质来源于围岩,热液主要来自大气降水。因此,认为本矿床实属产于寒武系轻变质岩中的层控矿型大气降水热液铅锌矿床。

汪民在全国地质勘查管理座谈会上指出矿业权管理要依法予以规范

在7月16目召开的全国地质勘查管理座谈会上，国土资源部副部长汪民指出，按照我国法律法规，探矿权两级管理、采矿权四级管理，不存在初审问题。     

海岩小说的几种叙述模式及弊端

海岩的长篇小说《河流如血》再创出版高记录，但作家仍局限于特有的小说叙述模式，这部作品设能做到相应的创新。概言之，模式第一面是“刑侦＋恋爱”；模式第二面是“财子＋佳人”；模式第三面是“道德＋法制”。文学创作需要不断创新，创新的过程也是对创作模式的不断突破过程。作家应该警惕的是，不要让模式成为创作的桎梏。     

The Geologic Time Scale and the Italian stratigraphic record

The construction of the Geologic Time Scale (GTS) is a titanic scientific challenge that has been under way for two centuries and will require much dedicated effort in the future. Italy preserves a paramount stratigraphic record of Mesozoic and Cenozoic marine sediments that have been significant in the development of the modern GTS. The Italian stratigraphic record has been histori-cally important in introducing and defining the standard Chronostratigraphic Units (CUs) of the Neogene and Quaternary. Pelagic successions from Northern Apen-nines and Southern Alps have been used in the seventies for integrating the late Cretaceous-Paleogene Geomag-netic Polarity Time Scale (GPTS) with planktonic microfossil biostratieraohv and standard CUs. This was a major contribution to the construction of a new gener-ation of GTS based on integrated magnetobiochronol-ogy. The middle Miocene to early Pleistocene marinerecord from Sicily and southern Italy has been funda-mental for establishing the recently developed Astro-nomical Time Scale (ATS). In prospect, there are many potentials still to be exploited in the Italian marine stratigraphic record for implementing the GTS by defin-ing GSSPs of various CUs, improving magneto-biochronology and extending downwards the ATS.
