山高水长路漫漫——纪念丁文江先生

丁文江先生是我国近代地质学的奠基人之一，也是中国地质学会的主要创始人之一。他在地质学的诸多领域都开展了卓有成效的工作，组建了我国最早的地质调查和科研机构，立德树人，培养了第一代地质学家，主导了前中央研究院的重大机构改革，为地质甚至科学事业在中国的落地生根起到了决定性的作用。同时他也积极参与到当时的社会和政治活动中，践行自己报效国家的理念。他是在我国开展系统性区域地质调查的第一人，开启了中国人系统地质填图的先河，先后填制了诸多不同比例尺的地质图，为后世我国构造地质界奠定了研究传统。他填图的区域从克拉通到造山带，从弱变形区到强变形带，填制的地质图也从简单到复杂，从关注地层到构造内容的逐步增加，不仅体现了一个地质学家野外填图经验和技术的逐步成熟，也体现了我国构造地质学逐渐从地层学中独立出来的过程。这个过程与国际上构造地质作为一个独立的专业从地层学中分离出来的阶段一致。因此丁文江先生不仅仅是我国地质学的奠基人之一，更是我国构造地质学的开山宗师。丁文江先生始终怀揣科学救国的信念，将自己的一生融入到科学救国、传播科学思想的过程中，将自己的科研活动与当时的国家建设联系，积极参与多项铁路选址、矿产调查与开发以及生态环境变迁等工作，这永远值得我们学习。他为中国地质学乃至科学发展做出的贡献永载史册。

Relations Between Igneous and Metamorphic Rock Fracture Patterns and Groundwater Yield from the Variography of Water–Well Yields—Pinardville Quadrangle,New Hampshire

Exploratory variography was used to examine the spatial continuity of water–well yields in the Pinardville 7 Minute Quadrangle in southern New Hampshire and to link the variography to the characteristics of the fractured igneous and metamorphic rocks within the aquifer system. In addition to the analyses of variograms computed by using data from 939 wells, analyses were performed on subsets of the data that were stratified according to the level of yield and to five rock types. The stratification according to yield was defined by using the industry standard of a high-yield well that produces 40 gallons per minute or more. The stratification of the low-yield wells by rock type was defined by using the classification on the bedrock map for the State of New Hampshire. Although the variability is high in the low-yield wells, as indicated by the large nugget value, overall continuity ranges to 6000 feet in the fracture zones in which these wells have been drilled. This continuity is dominant in the northwesterly direction, as indicated by the directional variography. This result is consistent with the general trend in the larger tectonic configuration of the region. A lack of spatial correlation for 81 high-yield wells is consistent with the geologic interpretation that these wells occur in locally determined configurations of sheeting and steeply dipping fractures. Yield data in only three of the five rock types were sufficient for variography. Within these three, the dominant direction of the correlation structure ranged from northwesterly for the Massabesic Gneiss Complex to northeasterly for the Rangeley Formation to northerly for the Spaulding Granite, where the signature of the continuity in the low-yield wells is predominately attributed to the fracture system.     

变质地质学的三大前缘课题

本文主要从三个方面反映１９８７年以来国内外变质地质学研究的新进展：（１）变质Ｐ－Ｔ－ｔ轨迹与区域岩石学研究；（２）变质流体与岩石的相互作用；（３）高压、超高压变质。变质ｐ－Ｔ－ｔ轨迹按地壳拉张区、地壳增厚区、俯冲带和麻粒岩相变质地区等不同构造环境予以论列；变质流体岩石的相互关系是按区域变质、接触变质和麻粒岩相变质地区等三个类型对比描述。高压、超高压变质研究近年来得到快速发展，也提出了许多问题。本文主要介绍柯石英榴辉岩岩石学和榴辉岩相岩石学的主要问题。

南海珠江口盆地工程地质分区与评价

本文根据联合国开发计划署（UNDP）援华项目（CPR/85/044）资料撰写的。划分工程地质区及亚区的目的，在于了解区域工程地质条件的共性与差异性，以求在海洋开发中科学地利用和改造自然。本项研究是在大量地质-地球物理-土工测试基础上进行的，工作扎实，内容丰富，资料准确可靠。根据工程地质条件的相似性与差异性，将珠江口盆地划分为两个大区5个亚区，并研究了各区工程地质特征及主要问题。其中以中陆架混合土亚区工程地质条件最好，外陆架粗粒土亚区工程地质条件较好，上陆坡软土亚区工程地质条件最差，内陆架细粒土亚区和上陆架岩石、礁石亚区工程地质条件较差。本项研究成果为南海海洋开发与总体规划提供了科学依据，同时又促进了海洋工程地质科学的发展。

From data gathering to resources assessment: A holistic view of petroleum geology

To integrate geological data to obtain an interpretation of the geology and natural resources of an area, we need a methodology that provides a holistic approach, addressing all basic issues in geological relations as well as uncertainties that arise with the evolution of basic geological knowledge of an area.In spite of the major role played by geoinformatics—the application of mathematics, statistics, and computer science to solve geological problems—we do not yet have a properly designed method for organizing geological data, including raw data, conceptual models, modeling results, and geological integration. Such a rapid method should provide for updating of existing interpretations based on new data or new theories.A systematic view of data integration and interpretation is important in petroleum exploration and petroleum engineering. We point out the more striking tools already available but of restricted use and some of the possible solutions for known problems that still require research and development.
