This proposal requests funding to complete work on the NAVDAT database and web portal. The aim is to finish populating the database with age and chemical data from Cenozoic and Mesozoic extrusive and intrusive rocks for western North America, from the Cascades southward through central Mexico. Most management of the NAVDAT system will be transferred to the EarthChem effort by the end of the project. The proposed work will focus on the following tasks:1. Expand database content bya. continuing to enter data for Cenozoic and Mesozoic rocks in western NA, with specific emphasis on intrusive igneous rocks;b. helping to facilitate ongoing efforts by researchers based in Mexico to gather and compile new data for that region for rocks of similar age;c. linking to the extent possible with efforts by groups in Canada and the US Geological Survey to further expand data holdings.2. Improve usability of the web portal bya. continuing to refine the user interface and search selections;b. adding additional options for query such as volcanic field names and creating precompiled datasets based on location, composition, and age;c. improving interaction with the website by incorporating routines for userdefined animations, data output formats, and plotting/mapping.3. Build community involvement bya. continuing to hold yearly workshops that involve a large and diverse group;b. working closely with international groups, particularly in Mexico;c. collaborating with the EarthChem effort.Intellectual Merit of the proposed work lies in the challenges of serving and maintaining a large database containing heterogeneous data. In addition, migration of database management to the EarthChem system presents an opportunity to prototype such transitions; migration of this sort must become common as more databases are created. The investigators also anticipate that fundamental new understandings about the dynamics of the solid Earth such as the relation of magmatism to tectonics will be emerge from the proposed work.Broader Impacts. The NAVDAT project will give students and researchers access to high-quality data compilations on their desktop, with the capability to extract datasets, plot chemical variation diagrams, and place data on a variety of geological, geophysical, and geographical base maps. The proposed work will expand the geographical and age range of available data, as well as building a very complete dataset for western North America. This work will lead to completion of a major component of the EarthChem system.

该提案要求提供资金，以完成NAVDAT数据库和门户网站的工作。其目的是完成填充数据库的年龄和化学数据，从新生代和中生代喷出和侵入岩的北美西部，从南部的瀑布到墨西哥中部。NAVDAT系统的大部分管理工作将在项目结束时移交给EarthChem。拟开展的工作重点如下：1.通过a展开数据库内容。继续输入NA西部新生代和中生代岩石的数据，特别强调侵入火成岩;B.帮助促进墨西哥研究人员正在进行的努力，以收集和汇编该地区类似年龄岩石的新数据;c.尽可能与加拿大和美国地质调查局的团体合作，进一步扩大数据库。2.提高门户网站的可用性。继续细化所述用户界面和搜索选择;B.添加用于查询的附加选项，诸如火山油田名称，并且基于位置、组成和年龄创建预编译数据集;c.通过结合用户定义的动画、数据输出格式和绘图/映射的例程来改善与网站的交互。建立社区参与。继续每年举办有大量不同群体参加的讲习班;B.与国际团体密切合作，特别是在墨西哥;c.所提出的工作的智力价值在于服务和维护包含异构数据的大型数据库的挑战。此外，将数据库管理转移到EarthChem系统提供了一个机会，可以对这种过渡进行原型设计;随着更多数据库的建立，这种转移必须变得普遍。研究人员还预计，有关固体地球动力学的基本新认识，如岩浆活动与构造的关系，将从拟议的工作中出现。 NAVDAT项目将使学生和研究人员能够在桌面上获得高质量的数据汇编，能够提取数据集，绘制化学变化图，并将数据放置在各种地质，地球物理和地理基础地图上。拟议的工作将扩大可用数据的地理和年龄范围，并为北美西部建立一个非常完整的数据集。这项工作将导致完成地球化学系统的一个主要组成部分。
