摘要:河流砂碎屑组分的鉴定和统计是物源分析的关键步骤,传统显微镜鉴定和人工统计过程费时费力,所获得的数据标准不一,质量参差不齐,不同实验室所获得的数据对比性较差。使用机器辅助技术实现碎屑组分自动鉴定是地质学家的夙愿。要实现这一目标,需要专业地质人员拍摄和标记显微图像文件作为训练基础。基于数据公开、共享的原则,作者将前期耗费大量时间和精力所标记的图像数据集发表出来,供感兴趣的地学、计算机等领域研究人员共享。本数据集包含8734个标记好的碎屑颗粒的图像和坐标文件,1536张高清砂粒显微图像,120张编号标记底图和两个砂粒成分鉴定表。本数据集可以作为机器学习训练集,也可以作为鉴定其他河流砂碎屑组分的参考。

Abstract & Keywords
Abstract: Identification and statistics of reproduction of river sand and sediment components are the key steps of provenance analysis. The traditional human identification and manual statistics process are time-consuming and laborious, and the data obtained are of different standards and of uneven quality. The data obtained by different laboratories are of poor contrast. The automatic identification of sand components by computer using machine learning technology can help geologists relieve themselves from this tedious and time-consuming work. To achieve this goal, professional geologists need to take and mark a large number of microscopic image files as a basis for training. However, the large number of computer workers who want to do this work cannot find such datasets. Based on the principle of data disclosure and sharing, the author published the marked image dataset which had spent a lot of time and energy before. The dataset consists of 8,734 tagged clastic particle images and coordinate files, 1,536 sand microscope images, 120 numbered base maps and two sand composition identification tables, which provides a large number of data bases for computer automatic identification of sand components using machine learning techniques, and can also serve as reference standards for identification of other river sand detrital components.
