冲积沉积构型单元分析法——原理及其适用性

通过对构型单元分析法原理和构型单元界面定义的回顾并结合对延长组的研究，发现构型单元分析法适用于以冲积作用为主要沉积物搬运方式的沉积地层。对岩性呈渐变过程、界面类型单一、界面级别难以确定、成岩改造强烈、同沉积变形发育以及底辟作用强烈的地层，不宜使用构型单元分析法。在河口湾、潮间带和河流三角洲前缘环境中形成的沉积体也不适合进行构型单元分析。

Petroleum inclusions in sedimentary basins: systematics, analytical methods and applications

Fluid dynamics in sedimentary basins is of tremendous interest, both from a scientific and an economic point of view. Integration between fluid inclusion and present-day fluid data provides the time aspect necessary for reconstruction of fluid flow paths, and can be used for mapping fluid dynamics both on a regional basin scale or on the more local scale of petroleum reservoirs. This paper presents a review of analytical and modelling methods for petroleum in fluid inclusions. Essentially, four types of data for petroleum inclusions can be established through analysis and modelling: (1) textures (which give indirect information of the time aspect), (2) fluid composition, (3) fluid properties and (4) pressure–temperature of trapping. During the last decade, development of analytical methods for determination of inclusion fluid compositions has taken place. Traditional correlation studies for characterisation of maturity and source facies may now therefore include fluid inclusion data. The development has also been directed towards an improved understanding of the physical properties of petroleum inclusions. Although these methods are in their early stages concerning precision and accuracy, data necessary for fluid flow modelling, such as fluid densities, viscosities, pressure and temperature, can be estimated.

The historic and artistic heritage facing the earthquake risk: The Italian case

The problem of protection against earthquakes in Italy is made difficult by the presence of a huge historic and artistic heritage. Such a heritage is mainly made up of ancient buildings and monuments situated in the urban centres, which are densely distributed throughout Italy. Therefore, very complex problems are met in the determination of the value parameter concurring with the determination of seismic risk, in addition to hazard and vulnerability. An indication of the monetary value of a building is not sufficient as far as the cultural heritage is concerned: different criteria are necessary in order to distinguish which are the strategic buildings. If we consider that there are more than 2000 museums in Italy, most of which are placed inside historic buildings, it appears that museums should receive the highest priority in future initiatives for seismic rehabilitation.     

东秦岭泥盆系沉积岩相地质遗迹及保护意义

建立于秦岭腹地柞水、镇安两县交界的泥盆系沉积岩相地质剖面，有陆相冲积相、过渡相河口湾相、海潮坪相、陆棚相、局限台地相、开阔台地相、台缘生物礁相、台缘斜坡相及次深海盆地浊积岩相，整体反映一微型镶边碳酸盐台地的形成与消亡，保护该地质遗迹对地质科学研究具有重要的实际意义。该剖面已被批准为陕西省第2号自然保护点，并已立碑保护。     

甘肃西成铅锌矿田中泥盆统碳酸盐沉积相的初步研究

本文根据岩石类型、沉积构造、生物组合和指相矿物将西成矿田中泥盆统碳酸盐沉积划分为两个相带,7个相和11个亚相,即碳酸盐台地相带和碳酸盐台地边缘相带;台地潮坪相、局限台地相、半开阔台地相、开阔台地相、台缘前斜坡相、生物滩层礁相和礁相。可以看出,区内铅锌矿床的形成和分布明显受着碳酸盐沉积相带的控制。     

Spatial and temporal trend of sewage pollution indicated by coprostanol in Macao Estuary,southern China

Bottom sediments and a ²¹⁰Pb dated sedimentary core in Macao Estuary were quantitatively analyzed with GC-MS for coprostanol and other sterols. Higher coprostanol concentrations were detected at Port Interior and Lower Qianshan River, indicative of serious sewage pollution from densely populated Macao Island and Zhuhai City. However, very low concentrations of coprostanol were detected around Coloane Island as well as Port Exterior and Maliuzhou River except sites adjacent sewage outlets. Coprostanol pollution in Macao Estuary originates mainly from locally direct discharge of untreated wastewater. The concentrations of coprostanol in ZJ-9 were mainly in range of 150–280 ng/g with an average of 210 ng/g for more than 20 years from early 1970s to early 1990s. However, it increased obviously since 1993, and reached the highest in 1995–1996. However, a sharp decrease of coprostanol concentration from 470 to 31 ng/g after 1996 was observed corresponding to the first wastewater treatment plant in Taipa Island going into action.
