MOESM4 of Seafloor hydrothermal alteration affecting magnetic properties of abyssal basaltic rocks: insights from back-arc lavas of the Okinawa Trough

Additional file 4: Figure S1. Backfield DC demagnetization curves of the studied lava samples; 6K#569R4-2, 6K#569R4-3, 6K#562R1, and 6K#569R4-1. The measurements were taken in limited field range to extract only remanent coercivity (Hcr). The 6K#569R4-3 sample display both fresh (solid line, top) and altered (broken line, bottom) specimens.
