This is the anisotropy of magnetic susceptibility (AMS) data from a 3km thick section of redbeds in the Gonjo Basin in eastern Tibet that was analysed by li2020an;textualTFORGE.
GonjoA list with entry datatable containing one row per specimen and entry matrices containing the AMS tensor (i.e. symmetric matrix) for each specimen.
The datatable entry has 542 rows and 25 variables:
Name: character — Specimen name
really depth: double — Depth of specimen (in meters)
Field: double — Unsure — li2020an;textualTFORGE say they applied a 300 A/m magnetic field
Freq.: double — Frequency of oscillation of the applied magnetic field
Km: double — Mean magnetic susceptibility
L: double — Lineation (\(\lambda_1 / \lambda_2\))
F: double — Foliation (\(\lambda_2 / \lambda_3\))
P: double — Uncorrected degree of anisotropy (\(\lambda_1 / \lambda_3\) )
Pj: double — Corrected degree of anisotropy
T: double — Shape factor
U: double — Unsure
Q: double — Unsure
E: double — Unsure
K1decI and K1incI: doubles — In-situ direction of first eigenvector
K2decI and K2incI: doubles — In-situ direction of second eigenvector
K3decI and K3incI: doubles — In-situ direction of third eigenvector
K1decT and K1incT: doubles — Tilt-corrected direction of first eigenvector
K2decT and K2incT: doubles — Tilt-corrected of second eigenvector
K3decT and K3incT: doubles — Tilt-corrected of third eigenvector
The AMS matrices were calculated using the in-situ directions by Dr. Janice Scealy.
