(Table 11) Major element compositions of manganiferous ilmenite and pyrophanite, magnesiochromite, actinolite, and chlorite at DSDP Sites 67-499 and 67-500

From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

空单元格代表无有效数据。1983年至1989年间，美国国家海洋和大气管理局国家环境信息中心（NOAA-NCEI）从期刊论文、技术报告及其他机构的未公开数据源中，汇编生成NOAA-MMS海洋矿物地球化学数据库。彼时，该数据库是全球范围内最全面的铁锰矿床相关数据汇编成果。由于该数据库最初采用的专有格式与现行标准不兼容，阿尔弗雷德·魏格纳研究所（AWI）与NOAA联合决定，将这批历史遗留数据转录至PANGAEA数据库。此次数据迁移工作还补充了对可获取原始文献的严谨核查，以及对NOAA-MMS数据库未收录的辅助信息（如样品描述、分析方法等）的编码处理。
