Grain Size Distribution of slickenlines from Plan de los Platanos and Big Piute Faults
收藏资源简介：
Grain Size Distribution (GSD) of Plan de Platanos (<strong>PP</strong>) and Big Piute (<strong>BP</strong>) Fault Slickenlines Grains were manually segmented from images of increasing magnifications obtained through optical and SEM microscopy. The size of the grains was then estimated from the grains' area by calculating the diameter (<strong>d<sub>equ</sub></strong>) of a circle of equivalent area. <strong>Instruments:</strong> ZEISS AX10 Petrographic microscope ZEISS Merlin HR-SEM (BSE) <strong>PP</strong>---> sample <strong>PP_AU01a</strong>_--> Orientation <strong>XZ</strong>---->N=8439----->andesite <strong>BP</strong>---> sample <strong>BP_07b</strong>--> Orientation <strong>YZ</strong>---->N=11425------>quartzite <strong>Unit of length (1st colum): </strong>micro meters <strong>(µm</strong>) We use Tikoff et al (2019) naming convention for thin section orientation.
