What is this site?
This is a collection of seafloor fabric lineations, including fracture zones, extinct ridges, V-anomalies,
discordant zones, and propagating rifts.
The latest snapshot of the sea floor fabric data base can be found here in three different file formats:
- OGR/GMT multisegment files (as bzipped tarball).
- KMZ Google Earth files.
- ESRI Shapefile files (as zipped archive).
- 2015-03-24: Based on VGG 23.1, Kara Matthews added 85 new FZs, revised the extent of 156, and deleted 11.
- 2014-01-06: Added 9 FZs for the Ellice Basin (Mike Chandler).
The software used to refine seafloor fabric traces from guide points and VGG grids and to convert Chron names to actual
ages using magnetic timescales is available as a custom GMT 5.2 supplement.
Thus, you must install GMT (5.2 or later) before building
the GSFML supplement (GMT 5.2 was released Nov 12, 2015. After GMT 5.2 is installed and in your path you can
download the GSFML supplement for GMT 5.2
and follow the build instructions in the README.gsfml file. Once installed the three GSFML modules are available via
the gmt executable (and the four bash scripts will be in your executable path).
