Data for: Breaking up and making up - reworking of Holocene calcarenite platform into rapidly-forming beachrock breccia on a high energy coastline (St. Lucia, South Africa)

At Mission Rocks Beach at the KwaZulu-Natal coastline in South Africa a coastal calcarenite platform is eroded by high wave energy and simultaneously mended by a quickly forming beachrock. The beachrock forms as infill of erosion-structures within and on top of the platform and thus above the intertidal zone. It was investigated regarding its sedimentology, petrogaphy, geochemistry and age to unravel its process of formation. This dataset contains fieldwork documentation in form of photos and sedimentological profiles, petrographic and SEM images and EDX spectra taken from three samples of beachrock.在南非夸祖鲁-纳塔尔海岸沿线的使命岩海滩，一处海岸钙结岩（calcarenite）平台正遭受强波浪能侵蚀，同时又被快速形成的海滩岩（beachrock）填充补缀。该海滩岩以填充体的形式形成于平台内部及其顶面的侵蚀构造中，因此位于潮间带之上。研究人员针对其沉积学、岩石学、地球化学特征以及形成年代展开了调查，以阐明其形成过程。本数据集包含从3块海滩岩样本中采集的野外工作文档，具体形式包括照片、沉积学剖面、岩石学图像、扫描电子显微镜（Scanning Electron Microscope，SEM）图像以及能量色散X射线光谱（Energy Dispersive X-ray Spectroscopy，EDX）谱图。
