浅海结构知识库（SMAKS）是一个关系型数据库，用于存储有关古代浅海和泥质硅质岩序列的沉积结构以及相应现代环境的地貌组织的硬数据和软数据。该数据库允许纳入已发表文献中的数据，这些数据被上传到一个共同的标准，以确保数据定义的一致性。该数据库包括关于不同性质和规模的地质实体的数据（即，表面、沉积域、结构要素、层序地层单元、相单元、地貌要素），包括表征它们的类型、几何形状、空间关系、层次关系和时间意义的属性。此外，地质实体被分配给沉积体系或其部分，其可以根据多个参数（例如，搁板宽度，增量集水区）与元数据（例如，数据类型、数据源）。SMAKS允许对现代和古代浅海和碎屑岩沉积体系进行定量表征。该数据库旨在作为含油气序列的模拟信息库，并作为一种研究工具，可用于帮助开发相模型或评估沉积体系对特定控制因素的敏感性。数据库输出的例子是：（i）包括波浪、潮汐和河流主导的浅海和沉积序列的数据，（ii）覆盖从后滨到陆架边缘的广泛沉积范围。这些例子包括不同类型的沉积亚环境的相组织的信息，在第四纪三角洲，现代和第四纪潮汐沙脊的形态，并在准层序规模的近岸砂岩带的几何形状，从上白垩纪的西部内陆航道在犹他州（美国）的建筑元素，形成三角洲构造单元的层次安排。(C)2016爱思唯尔有限公司版权所有。
The Shallow-Marine Architecture Knowledge Store (SMAKS) is a relational database devised for the storage of hard and soft data on the sedimentary architecture of ancient shallow-marine and paralic siliciclastic successions, and on the geomorphological organization of corresponding modern environments. The database allows incorporation of data from the published literature, which are uploaded to a common standard to ensure consistency in data definition. The database incorporates data on geological entities of varied nature and scale (i.e., surfaces, depositional tracts, architectural elements, sequence stratigraphic units, facies units, geomorphic elements), including attributes that characterize their type, geometry, spatial relations, hierarchical relations, and temporal significance. Furthermore, geological entities are assigned to depositional systems, or to parts thereof, that can be classified on multiple parameters (e.g., shelf width, delta catchment area) tied to metadata (e.g., data types, data sources).The SMAKS permits the quantitative characterization of modern and ancient shallow-marine and paralic clastic depositional systems. It aims to serve as a repository of analogue information for hydrocarbon-bearing successions, and as a research tool that can be applied to aid the development of fades models or to assess the sensitivity of depositional systems to particular controlling factors, for example.To demonstrate the wide applicability of the database in fields of both fundamental and applied research, example database output is presented that (i) includes data from wave-, tide-, and fluvial dominated shallow seas and sedimentary successions, and (ii) covers a wide depositional spectrum, from backshore to shelf-edge settings. The examples include information on the facies organization of different types of paralic sub-environments, on the hierarchical arrangement of architectural elements that form deltaic constructional units in Quaternary deltas, on the morphometry of modern and Quaternary tidal sand ridges, and on the geometry of parasequence-scale nearshore sandstone belts from the Upper Cretaceous of the Western Interior Seaway in Utah (USA).
