Permeability Anisotropy Data
----------------------------

Data was gathered primarily from E.Michie PhD project (2010-2013, University of Aberdeen) and I.Kaminskaite PhD project (2015-2019, Carbonate Fault Rock Project, University of Leeds), with some from A.Cooke PhD project (2015-2019, Carboante Fault Rock Project, University of Leeds)


Description: This spreadsheet provides the permeability and some porosity data from fault rock and respective host rocks used for the publication Michie & Kaminskaite, 'Permeability Anisotropy in Carbonate Fault Rocks', subitted to JGR Solid Earth.  Readers are referred to this publication for details on permeability and porosity measurement methodology.

Permeability Anisotropy Data.xlsx
=================================

Sheet 1: Fault Rock.  Contains all data from fault rock samples used in this publication.
Core plug no. - a unique sample number identifier.  Relates to sample numbers used in the publication
Kg fault x, y and z - gas permeability for core plugs oriented into the x- y- and z- orientation (along, down and across fault, respectively). Measured in millidarcys (mD).
Fault - name of fault where sample is taken.  SQF: South Qala Fault, Gozo. Qala: Qala Point Fault Zone, Gozo. VLF: Victoria Lines Fault, Malta. Def Band: Deformation Bands, NW Sicily. Faro Fault, Torre Isolidda, Punta Negra 3 and 2: NW Sicily. Readers are referred to the publication for more locality details.
Fault porosity x, y and z - porosity for core plugs oriented into the x- y- and z- orientation (along, down and across fault, respectively).  As a percentage.

Sheet 2: Host Rock.  Contains all data from host rock samples used in this publication.
Sample: Name of sample used in this publication.
Description: Formation / description of host sample.  Attard, Xlendi and LGL are member names on Malta.  Attard: Attard Member of the Lower Coralline Limestone Formation, algal packstone. Xlendi: Xlendi Member of the Lower Coralline Limestone Formation, bioclastic packstone. LGL: Lower Globigerina Limestone Member of the Globigerina Limestone Formation, fine-grained wackestone.  Grainstone and recrystallised are descriptive terms for the host samples.  Readers are referred to the publication for more host description details.
Kg host x, y and z - gas permeability for core plugs oriented into the x- y- and z- orientation (along and across bedding, respectively).  Measured in millidarcys (mD).
Host porosity x, y and z - porosity for core plugs oriented into the x- y- and z- orientation (along and across bedding, respectively).  As a percentage.
