Fracturing and healing of basaltic magmas during explosive volcanic eruptions

Raw measurements of fracture parameters in volcanic and experimental products. Point count measurements of intact crystals, crystal fragments, and vesicle-free area for all the 30 images of the mosaic in Extended Data Figure 1. Point count and image segmentation crystallinity for all measured images of natural and experimental products.火山岩产物与实验合成产物的断裂参数原始测量数据。针对扩展数据图1中镶嵌图的全部30幅图像，开展完整晶体、晶体碎片及无泡区域的点计数测量。针对所有天然产物与实验产物的待测图像，采用点计数法与图像分割法完成结晶度分析。
