METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data:  The sampling campaigns were designed to carry out five detailed transects in N-S and NE-SW directions in the Cadí basin with a total of 56 sampling sites: Argestués (4 sites), Cerc (17 sites), El Ges (7 sites), Coll de Vanses (13 sites) and Ansovell (15 sites) sections. The samples were directly obtained in the field as cylindrical cores with gasoline and battery-powered drill machines cooled with water or as oriented blocks taken with extraction tools. In the block sites, one to four blocks per site were taken and in the 33 drilled sites an average value of eight cores per site was obtained. All simples were oriented with a magnetic or a solar compass, and sampling localitieswere positioned with a GPS. Oriented cores and blocks were cut to 2.1 cm-long, 2.5 cm-diameter standard cylinder specimens and 2 cmedgestandard cube specimens, respectively, using a radial sawand a diamond drill bit (non-magnetic steel). Bedding or flowplaneswere measuredin most sampling sites.Anisotropy of magnetic susceptibility (AMS) measurements at room temperature (RT-AMS) were conducted at the Magnetic Fabrics Laboratory of the University of Zaragoza, Spain, using a Kappabridge KLY-3S (AGICO Inc.).

2. Methods for processing the data: The susceptibility tensor was calculated, including statistical confidence angles (e12, e13, e21, etc…), with the software SUSAR (AGICO Inc.). The AMS values for all specimens from each site were processed and represented using the software Anisoft 5.1.03.

 

3. Instrument- or software-specific information needed to interpret/reproduce the data, please indicate their location: Kappabridge KLY-3S, software: SUSAR, Anisoft 5.1.03

4. Standards and calibration information, if appropriate: Standard specimens dimensions: 2.1 cm-long, 2.5 cm-diameter for the standard cylinder specimens and 2 cm edgefor standard cube specimens.

5. Environmental/experimental conditions: AMS measurements at room temperature.

6. Describe any quality-assurance procedures performed on the data:
