Microfossils - Value Added Dataset

Microfossil samples submitted to the BGS biostratigraphy laboratory are currently registered using the prefix 'MPA'. Samples include rock, residues from sample preparations, and slides of mounted specimens. Rock, residues and slides from the same sample all bear the same unique identifying sample number. The numbers MPA 1 to 54400 have been used, but this grows steadily. There are currently 21 volumes of registered samples. The value added dataset comprises data for each sample held in the sample register, including collectors' symbols and numbers, 1:10k (or 6") OS quarter sheet, NGR, 1:50k (or 1") geological sheet, borehole name and depth (if relevant), locality, geological formation and report numbers. The value added dataset also includes identifications of specimens on each slide, which are listed on logging sheets and are held separately.

提交至英国地质调查局（BGS）生物地层学实验室的微体化石样本，目前均以'MPA'作为前缀进行登记。样本类型包括岩石、样品制备残留物以及装片标本。同一样本的岩石、残留物和装片均携带相同的唯一标识样本编号。已使用的编号从MPA 1至54400，且数量持续增长。目前已有21卷登记样本。增值数据集包含了样本登记册中每个样本的数据，包括采集者的符号和编号、1:10k（或6英寸）OS四分图、NGR、1:50k（或1英寸）地质图、钻孔名称及深度（如适用）、地点、地层构造及报告编号。增值数据集还包括每个载玻片上标本的鉴定结果，这些结果列于记录表上，并单独保存。
