Descriptions

The island of Holsnøy is located in southwestern Norway. It is composed of metastable granulite facies lower crust that was subducted at 430 Ma when fluid infiltrated the region and reacted with large portions of the area to form eclogite facies shear zones. The eclogite facies assemblages contain garnet with granulite facies cores and eclogite facies fractures and rims.
This dataset contains quantitative electron microprobe transects from garnets from four different eclogite facies samples. They are divided into two groups: rim profiles that run from the garnet rims toward the cores, and fracture profiles that run perpendicular to eclogite facies fractures. Some profiles have 5–10 µm spacing and were collected at 15 kV accelerating voltage whereas others have 1 µm spacing and were collected at 10 kV which reduced analytical convolution and facilitated higher spatial resolution of the profiles.

Twelve quantitative chemical profiles were collected from garnets from four thin sections using the JEOL JXA-8530F field-emission gun electron probe microanalyzer (EPMA) at Yale University employing a focused beam, wavelength-dispersive spectrometers, linear off-peak background corrections, natural and synthetic standards, and ϕ(ρz) matrix corrections.
