Ptychotomography of Bishop Tuff Zircons (NERC Grant NE/P002498/1)

Nanoscopic (50 < size < 150 nm) magnetic particles embedded within the unaltered interior of mineral crystals like zircons (ZrSiO 4 ) make ideal candidates to record the information about the earth's magnetic field (geodynamo). Information regarding the magnitude of the field can be obtained by measuring the natural remnant magnetization (NRM) of these carriers and further information on the approximate size range of the carriers can be obtained by carrying out thermal remnant magnetization measurements (TRM). However very little is known about the actual morphology and spatial distribution of these carriers in order to understand the fundamental parameters influencing paleomagnetic recording. We propose to image pristine zircons crystals with simple geological histories containing large remnant magnetization using ptychotomography in order to investigate the size, shape and spatial distribution of nano-paleomagnetic carriers. This would also give us an opportunity to fine tune the ptychotomographic setup at I13-coherence branch. This data package consists of 3D maps of Bishop Tuff Zircons, relatively young. The folders contain a stack of .tiff files which can be loaded into imagej, dragonfly, aviso for segmentation purposes.

Statement
Ptychotomography is a three-dimensional, (comparatively) non-destructive imaging technique which combines ptychography with conventional tomography. We exploit high resolution 2D ptychographic projections obtained at various angles as a starting point which are then taken through the conventional tomographic processes of alignment and 3D reconstruction in order to obtain high resolution (better than 80 nm) 3D complex transmission maps of the samples under study. Reasonable fields of view, typically 50x50x70 ?m^3 can be obtained from this technique.
