The PINT database: a definitive compilation of absolute palaeomagnetic intensity determinations since 4 billion years ago

SUMMARY Palaeomagnetic field intensity measurements, derived from rocks with ages that span geological time, provide a crucial constraint on the evolution of Earth’s deep interior and its magnetic environment. The palaeointensity database PINT has been updated to version v.8.0.0 includes site-mean records spanning an interval 50 ka 4.2 Ga, compiling efforts palaeomagnetic community 1959 end 2019. Nearly all have assessed using qualitative reliability (quality palaeointensity, QPI) framework. This brings together harmonizes prior QPI compilation into unified referred as database, incorporating recent since 2014 assess QPI. spatio-temporal distribution is analysed, revealing substantial biases towards young (from Brunhes chron) in Northern hemisphere, intervals little no data duration 10s 100s millions years Palaeozoic Precambrian. General compliance characterized for which shows median scores range 2 3 (out total possible score 10), positive trend increasing studies published after year 2000. illustrates awareness what required establish confidence robustness large scale interpretations can be made these data.
