Global distribution and composition of Neogene-Quaternary intraplate volcanic rocks

Global database of  >20, 000 geochemical analyses of Neogene-Quaternary intraplate volcanic rocks. The database collates major, trace element and Sr-Nd-Pb isotopic data for whole-rock samples <20 Ma old that were published between 1990 and 2020. Database as published in Ball et al. (2021). Key publication: Ball, P. W., White, N. J., Maclennan, J., & Stephenson, S. N. (2021). Global influence of mantle temperature and plate thickness on intraplate volcanism.

背景概述

该数据集是一个全球性的地球化学数据库，包含超过20,000个新近纪-第四纪板内火山岩样品的分析数据，涵盖主量、微量元素及Sr-Nd-Pb同位素组成，数据来源于1990年至2020年的出版物。其特点在于聚焦年龄小于20 Ma的岩石，旨在支持研究地幔温度与板块厚度对板内火山作用的影响，相关成果发表于《自然通讯》期刊。
