SEM Image Database of Quartz Microtextures from Kinu River Sediments

This database contains high-resolution scanning electron microscope (SEM) images of quartz grain surfaces collected from modern fluvial sediments of the Kinu River, Japan. The dataset is intended to support research on sediment transport dynamics, grain-scale mechanical processes, and fluvial energy heterogeneity.本数据库收录了采集自日本鬼怒川（Kinu River）现代河流沉积物的石英颗粒表面高分辨率扫描电子显微镜（scanning electron microscope，SEM）图像。本数据集旨在为沉积物输运动力学、颗粒尺度力学过程以及河流能量异质性相关研究提供支撑。
