Compiling pygplates on WSL Debian

I ran into a strange set of issues when trying to compile pygplates on the Windows Subsystem for Linux (WSL). Despite having all the requirements installed (e.g. Qt5, Boost etc). the compiler complained about Qt5 libraries not being present:

/usr/lib/qt5/bin/uic: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

However, these are installed in /usr/lib/x86_64-linux-gnu/ like in any other Linux distro. Turns out that some other people have the same issues to load the shared Qt5 libraries when compiling software on WSL. This is solved by running the following line:

sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

Code.PaleoEarthLabs.org and Sourcehut

I am slowly moving my BitBucket and GitHub repositories to self-hosted Fossil repositories available at https://code.paleoearthlabs.org. This means, there will be public issue trackers, wikis and forums.

Most of them will be mirrored to sourcehut which is a blazingly fast, simple, and FOSS-based alternative to the major players which also comes with mailinglists, todo/issuetracker and a wiki.

My GIT repositories (downstream mirrors of Fossil repos and pure GIT repos) can be found here https://git.sr.ht/~chhei. Note that the Fossil repository mirrors will only receive changes downstream from the original Fossil repos.

The following code is available now:

Microplate modelling paper accepted for publication

Derek Neuharth's paper on the “Formation of continental microplates through rift linkage: Numerical modelling and its application to the Flemish Cap and SaoPaulo Plateau” has just been accepted from publication in AGU's G^3. A pre-print is available on EarthArxiv

Key Points:

  • Strike-perpendicular offset and crustal strength control the mode of rift segment linkage (microplate, oblique, or transform).
  • Rotating continental microplates form at offsets of >200 km for weak and moderately strong crust.
  • Modelled microplate evolution may explain the formation of the Flemish Cap, the Sao Paulo Plateau and other continental promontories.

Abstract:

Continental microplates are enigmatic plate boundary features, which can occur in extensional and compressional regimes. Here we focus on microplate formation and their temporal evolution in continental rift settings. To this aim, we employ the geodynamic finite element software ASPECT to conduct 3D lithospheric-scale numerical models from rift inception to continental breakup. We find that depending on the strike-perpendicular offset and crustal strength, rift segments connect or interact through one of four regimes: (1) an oblique rift, (2) a transform fault, (3) a rotating continental microplate or (4) a rift jump. We highlight that rotating microplates form at offsets >200 km in weak to moderately strong crustal setups. We describe the dynamics of microplate evolution from initial rift propagation, to segment overlap, vertical- axis rotation, and eventually continental breakup. These models may explain microplate size and kinematics of the Flemish Cap, the Sao Paulo Plateau and other continental microplates that formed during continental rifting worldwide.
