Paleomagnetic data under lava flows

Samples were collected under the June 27th Lava Flow (Hawai'i, USA), a lava flow on Rangitoto Island (Auckland, New Zealand), and an area that used to be covered by a lava flow on Puketutu Island (Auckland, New Zealand). The samples were then progressively thermally demagnetised. The data attached here can be viewed with the Remasoft software package (see link below).
