摘要: Abstract An open-access database has been set up to support the research project studying ‘Response of Humans Abrupt Environmental Transitions’ (RESET). The main methodology underlying this was use tephra layers tie together and synchronise chronologies stratigraphic records at archaeological environmental sites. information on occurrences, chemical compositions, glass shards from cryptotephra deposits found across Europe. data includes both RESET itself published literature. With over 12,000 major element analyses 3000 trace shards, relevant 80 late Quaternary eruptions, generated an important archive data. When added information, described here a total more than 22,000 nearly 4000 240 eruptions. In addition its associated data, new methods analysis for assessing correlations have developed as part project. particular approach using multi-dimensional kernel density estimates evaluate likelihood compositions matching is tested
