Finite strain analysis - Samples IESP3SP31, IESP3SP34, IESP3SP36, IESP3SP37 and IESP3CH09 (Punta Bianca, La Spezia, Italy)

This dataseset contains finite strain analysis data for the samples IESP3SP31, IESP3SP34, IESP3SP36, IESP3SP37 and IESP3CH09 (see details on the SESAR geo samples repository). It includes the high-resolution scans of the polished slabs used for finite strain analysis and the data processed with EllipseFit (copyright: Vollmer, 2014).

The samples are monogenic carbonate metabreccia (IESP3SP31 & IESP3SP34), polygenic metabreccia (IESP3SP36 & IESP3SP37) and a vesicled metavolcanite (IESP3CH09). The polished slabs, oriented parallel to the XZ and YZ sections of the finite strain ellipsoid, were processed with EllipseFit (Vollmer, 2015) to estimate the axial ratio Rf and the angle with the foliation (φ) of the deformed strain markers. See Dunnet (1969) and Lisle (1985) for details about the Rf/φ method. Samples were also processed using the Fry (1979) method. Fry graphs are provided for comparison.

本数据集收录了针对IESP3SP31、IESP3SP34、IESP3SP36、IESP3SP37及IESP3CH09样品的有限应变分析数据（详情请参阅SESAR地理样本库）。数据包括用于有限应变分析的抛光板的高分辨率扫描图像，以及使用EllipseFit（版权：Vollmer，2014）处理后的数据。

样品包括单源碳酸盐杂砾岩（IESP3SP31与IESP3SP34）、多源碳酸盐杂砾岩（IESP3SP36与IESP3SP37）及气泡状变质火山岩（IESP3CH09）。抛光板经过处理，使其与有限应变椭球的XZ和YZ截面平行，并使用EllipseFit（Vollmer，2015）进行处理，以估算轴率Rf及与片理的夹角φ（φ）。有关Rf/φ方法的详细信息，请参阅Dunnet（1969）和Lisle（1985）的研究。样品还采用Fry（1979）方法进行处理。提供Fry图以供比较。
