Palaeobiology and phosphorites of the Ediacaran Biskopas Formation: optical microscopy and SEM-BSE-EDS data (NERC grant NE/I005951/1)

The dataset documents microfossils (acanthomorphic acritarchs) and sedimentary structures within phosphorite pebbles and interstitial carbonate cements from the Ediacaran Biskopas and Biri formations, Hedmark Group, Norway. Data includes extensive optical microscopy images (~30,000) of the microfossils and structures; SEM-BSE images, EDS elemental map and spot point data of phosphatized and carbonate-hosted microfossils; BSE maps and EDS elemental maps of the sedimentary structures within phosphorite pebbles; sedimentary descriptions and detailed grain size counts for phosphorites; detailed spread sheets recording microfossil size ranges, microfacies distributions, and abundances.

本数据集记录了来自挪威赫德马克组Biskopas和Biri地层的磷块岩中的微化石（刺形有孔虫）和沉积结构。数据包括大量微化石和结构的显微镜光学图像（约30,000幅）；磷化微化石和碳酸盐基质微化石的扫描电子显微镜-背散射电子能谱（SEM-BSE）图像、能谱分析（EDS）元素分布图和点分析数据；磷块岩内沉积结构的背散射电子能谱（BSE）图和EDS元素分布图；磷块岩的沉积描述和详细的粒度分析；以及记录微化石尺寸范围、微相分布和丰度的详细电子表格。
