Selective destructive demagnetization of breccias from DSDP Hole 83-504B
Listed in PANGAEA and DataCite — shown once because both records carry DOI 10.1594/pangaea.715073
The magnetization of four breccia samples from the Leg 83 section of DSDP Hole 504B was analyzed by selective destructive demagnetization in order to study the origin and stability of hydrothermally altered basalts.
Description
The NRM directions of the clasts for three of the four samples are randomly oriented and much more strongly magnetized than the bulk sample. Clasts which were individually demagnetized show two or more components of magnetization, but neither are coincident with those of the bulk sample, indicating that NRM was probably acquired prior to the consolidation of the breccia and suggesting that any overprint (VRM or otherwise) can be removed by AF demagnetization to at most 50 Oe.
Reflected light microscopy and electron microprobe analysis of two samples show that the unexpectedly high NRM of the matrix regions is apparently the result of secondary magnetic phases precipitated from hydrothermal solutions.
