VOLCORE(火山岩芯记录)数据库收集了34,696个可见的火山灰(火山灰、岩性或颗粒大小变化),在截至IODP Expesion381的所有深海钻探项目(DSDP;1966-1983年)、大洋钻探计划(ODP1983-2003年)、综合大洋钻探计划(IODP;2003-2013年)和国际海洋发现计划(IODP;2013年至今)的初次报告卷中报告了可见的Tephra事件。合并后的国际大洋钻探计划(OD)的地点覆盖全球。取芯的火山灰岩层和含火山灰的沉积物跨越了从最近到约1.5亿年的时间尺度。该数据库收集了所报告的全部或主要由火山灰组成的可见火山灰岩层的信息。数据包括海底深度、冰盖厚度、位置和任何报道的评论。使用已发表的年龄深度模型估计了大多数(29,493)Tephra层的大致年龄。该数据库可作为年代学、火山学、地球化学、沉积物运移和古气候学研究的起点。描述上报数据的机器可访问的元数据文件:10.6084/m9.figShar.12951347
The VOLCORE (Volcanic Core Records) database is a collection of 34,696 visible tephra (volcanic ash and lithological or grain size variations) occurrences reported in the initial reports volumes of all of the Deep Sea Drilling Project (DSDP; 1966–1983), the Ocean Drilling Program (ODP; 1983–2003), the Integrated Ocean Drilling Program (IODP; 2003–2013) and the International Ocean Discovery Program (IODP; 2013-present) up to and including IODP Expedition 381. The combined international ocean drilling programmes (OD) have locations with global coverage. Cored tephra layers and tephra-bearing sediments span timescales from recent to ~150 million years in age. This database is a collection of information about reported visible tephra layers entirely or predominantly composed of volcanic ash. Data include the depth below sea floor, tephra thickness, location, and any reported comments. An approximate age was estimated for most (29,493) of the tephra layers using published age-depth models. The database can be used as a starting point for studies of tephrochronology, volcanology, geochemistry, studies of sediment transport and palaeoclimatology.
