Tectonic maps for data analysis applications in solid Earth science

2022 May 22 Updated plates, boundaries, oc_boundaries and global_gprv following review. Formats are provided as shapefiles (shp), generic mapping tools (GMT), and keyhole markup language (KML) for use with Google Earth, each in separate folders.

2021 July 19 The global_tectonics package is a set of shapefiles that can be used for analysis of Earth science data. For each shapefile, there is an associated *.gmt file in Generic Mapping Tools (GMT) vector format. There are several models as part of the package, which includes a present-day plate model and a geologic province model. The models include metadata that permit the creation of several related (and seamless) maps including the lithospheric type (oceanic/continental), last orogenic event, and oceanic domains. It consists of four separate shapefiles:

plates.shp - polygons of tectonic plates and crust types

boundaries.shp - lines of plate boundary types

oc_boundaries.shp - lines demarcating the ocean-continent boundary

global_gprv.shp - polygons of global geologic provinces

cratons.shp - regions with geochemical samples or that are known to have Archean (>2500 Ma) basement; the polygons have largely been extracted from global_gprv.shp aside from a few in the western US from Lund et al. (2015, https://doi.org/10.3133%2Fds898); an additional column in the attribute table has been added to identify post-Archean reworking

Details about the construction of the models is discussed in Hasterok, D., Halpin, J., Hand, M., Collins, A., Kreemer, C., Glorie, S., (submitted) New maps of global geologic provinces and tectonic plates, Earth Science Reviews.

A static version with additional global geophysical and tectonic datasets can be found with a QGIS project file on Zenodo data repository.

The model is intended to be updated as new knowledge is gained about the locations and processes affecting provinces. To do so requires community effort. The global_tectonics GitHub repository can facilitate these updates.

global_tectonics's Issues

Missing layers in GIS Project

Great resource!!

Describe the bug
A clear and concise description of what the bug is.

I donloaded the zip package from Zenodo and fired up the qgis project and the following layers are missing, perhaps intentionally, but maybe better to remove them for general consumption?

Missing layers:

cratons
global_geochemistry_cao
ne_10m_graticules
ne_10m_gs4_bounding_box
antarctica

To Reproduce
Steps to reproduce the behavior:
Open global_tectonics.qgz

Expected behavior
all layers in qgis project are available

Inconsistent licensing and extra files on zenodo

This repo has a GPL license, but https://zenodo.org/record/6586972#.Ys2ze-zMI-R says:

License (for files):
[ Creative Commons Attribution 4.0 International](https://creativecommons.org/licenses/by/4.0/legalcode)

Additionally, the zip contains data from other projects, but it's not clear that those files are from external sources and what their licenses are. The readme.txt doesn't contain license info for the included files.

Also, if you do another zenodo release, I suggest doing some cleanup that will make the data easier for folks to use.

• Don't use & in file or directory names
• Remove the __MACOSX tree
• Remove .DS_Store files
• Remove gdal generated .aux.xml files

Maybe:

• Don't include outside (aka "third party") data, especially large files like ETOPO1 and the Seafloor age. They are cool, but make your zip drastically larger. I know that makes the QGIS project less interesting.

Maybe it would be best to have two zenodo entries where one is just the new work in global_tectonics.

Plate.gmt problem

Hello,
I want to re-plot the plate.gmt to compare with Bird, (2003)
But I found that there is a line on the map (180,90) to (180,-90)
I don't know why dose this line plot in my map.

there is my gmt6 script

gmt begin GlobalPlate png,pdf
gmt coast -JH180/12c -Rg -B0 -W0.2p,100 -A10000
gmt basemap -BWSne+t"Global Plate"
gmt plot plates.gmt -W0.3p,red
gmt plot PB2002_plates.dig.txt -W0.3p,blue 
gmt end show

thanks!
