解释地震图像中的断层是创建地下地质模型的核心。通过学习获得的先验知识的使用使口译员能够从单一的观察转向基于他们可用的概念模型的合理解释。因此,教科书、文章和培训练习中提供的断层实例的数量和种类很可能是解释人员解释地震数据中真实断层几何形状的能力的决定性因素。我们分析了断层类型的差异和几何解释地震数据的学生之前和之后完成了一个硕士模块的构造地质学,并将它们与故障的特点,在模块和教科书中表示。我们建议,在早期的教学材料中观察到的正常平面故障的过度表示影响数据的解释,使这种故障类型和几何形状占主导地位的前模块的解释。然而,当学生接触到更大范围的故障模型在模块中,故障类型和几何形状的范围增加。这项工作探讨了模型可用性在解释中的作用,并倡导在培训材料中使用现实的故障模型。(C)2017作者爱思唯尔有限公司出版
Interpretation of faults in seismic images is central to the creation of geological models of the subsurface. The use of prior knowledge acquired through learning allows interpreters to move from singular observations to reasoned interpretations based on the conceptual models available to them. The amount and variety of fault examples available in textbooks, articles and training exercises is therefore likely to be a determinant factor in the interpreters' ability to interpret realistic fault geometries in seismic data. We analysed the differences in fault type and geometry interpreted in seismic data by students before and after completing a masters module in structural geology, and compared them to the characteristics of faults represented in the module and textbooks. We propose that the observed over-representation of normal-planar faults in early teaching materials influences the interpretation of data, making this fault type and geometry dominant in the pre-module interpretations. However, when the students were exposed to a greater range in fault models in the module, the range of fault type and geometry increased. This work explores the role of model availability in interpretation and advocates for the use of realistic fault models in training materials. (C) 2017 The Authors. Published by Elsevier Ltd.
