摘　　要：南京大学岩石学教学与研究有百年历史。岩石教学薄片在地质学人才培养中发挥了重要作用。这些岩石学教学薄片在损耗、遗失、补充、更新等过程中形成了目前这一批相对完善的薄片体系,包含了28种沉积岩、40种火成岩、40种变质岩,涵盖了3大类岩石中90%以上的常见岩石类型,囊括了95%以上地质学专业要求掌握的常见矿物类型、岩石结构等教学大纲。本数据集通过系统拍照、信息整理等方式将南京大学岩矿教研室师生们正在使用的岩石教学薄片进行电子信息化,一共完成108种岩石324个岩石薄片的2634张偏光显微照片的电子信息化。为更好地共享这些岩石学的教学素材,特将这些教学薄片的显微照片和教学薄片信息与国内外同行们共享,以便老师们在线上、线下教学中使用,或者方便学生们在线上开展专业进修与自学。此外,这批统一标准的高质量图像数据可以用于机器学习、岩石自动鉴定等交叉研究,也可以在生产实践中作为广告宣传、花样设计的素材。Thin sections have always played an irreplaceable role in the nearly 100-year history of petrology teaching and research in the School of Earth Sciences and Engineering,Nanjing University.Despite their depletion,loss,supplementation,and update,the thin sections at Nanjing University have formed a relatively comprehensive set,which include 28 types of sedimentary rocks,40 types of igneous rocks,and 40 types of metamorphic rocks.As a whole,they cover over 90%of common rock types,and contain more than 95%of the common minerals and rock textures mandated by the syllabus of geology.This dataset results from a collective endeavor to electronically informatize the thin sections currently used by Nanjing University for petrology teaching.It includes a total of 2634 polarized-light micrographs of 324 thin sections of 108 types of rocks.To facilitate petrology teaching material sharing,we present the photomicrographs and information tables of these thin sections here.This dataset can be used by instructors as teaching materials,or by students for professional training or self learning.In uniform standards and of high quality,these image data can be used for research on machine learning and intelligent rock identifications.These photomicrographs can also be used as materials for advertising and pattern design in production practice.
