9418200 Goldstein Whether or not large scale volume loss during slaty cleavage formation is a long-standing and important problem. Geometric stain analysis commonly concludes large volume loss, while chemical techniques generally find no evidence for such large losses, expect over very short distances. This project will use both approaches to deduce the role of volume loss in the deformational history of the Taconic slate belt. A variety of strain indicators and fossils are available, and the original composition of the shale may be preserved adjacent to buttressing objects. Results will be widely applicable in deformation models, restoration algorithms and in other slate terranes.

在岩石解理形成过程中是否存在大规模的体积损失是一个长期存在的重要问题。几何染色分析通常得出大体积损失的结论，而化学技术通常没有发现如此大的损失的证据，除非是在很短的距离内。本项目将使用这两种方法来推断体积损失在塔科尼克板岩带变形历史中的作用。有多种应变指标和化石可用，并且在支撑物附近可能保留了页岩的原始成分。研究结果将广泛应用于变形模型、恢复算法和其他板岩地形。
