Restoration of Heterogeneously Strained Cross-Sections

平衡横截面的技术在结构研究中很重要，因为“平衡”的截面表明该结构可能是由物理上合理的事件序列进化而来的。由于数据通常是有限的，平衡截面几乎总是受到约束，因此几种不同的解释可能满足截面平衡的标准。此外，所使用的有限元网格限制了应用，并且可能在技术上要求很高。本项目将开发一个计算机程序包，以扩大应用范围，包括时间序列和渐进非均质位移和应变。其目的是为构造地质学家提供一种工具，使其更容易从原始数据中构建平衡剖面，评估空间和时间的平衡，并提供交互式修改剖面解释部分的能力。结果还将应用于已记录足够结构数据的一些现有地区。

The technique of balancing cross-sections is important in structural studies because a "balanced" section indicates that the structure could have evolved by a physically plausible sequence of events. Because data are commonly limited, balanced sections are almost always under constrained and therefore several different interpretations may meet the criteria of section balance, Moreover, the finite element grids used limit the application and can be technically demanding. This project will develop a computer program package to expand the application to include the temporal sequences and progressive heterogeneous displacement and strain. The intent is to provide structural geologists with a tool to more easily construct a balanced cross- section from raw data, assess the balance in space and time, and provide the ability to modify interpretative parts of the section interactively. Results will also be applied to a number of existing areas where sufficient structural data have been recorded.
