Numerical models dataset: rifting in Large Igneous Province settings - The William's Ridge (Kerguelen Plateau)-Broken Ridge study case

Rift processes in continental and oceanic settings have been thoroughly studied through observational analysis and numerical models. However, limited observations and lack of numerical modelling showing rift evolution in Large Igneous Province settings leave a comprehensive understanding of rift mechanics unresolved. This dataset consists of input files for the creation of numerical models showing the thermo-mechanical evolution of rifting in Large Igneous Province settings, focusing on the William's Ridge-Broken Ridge study case." Model runs in the study used dealii 9.3.0.The ASPECT version can be found at: https://github.com/EstherHeck/aspect/tree/fastscape_update_again_erosional_base_level-undo2780-before-rebase-on13mai22-Kais-and-ZhiChens-VersionThe FastScape version can be found at:https://github.com/Djneu/fastscapelib-fortranTo install this version of ASPECT with FastScape:1. Create a build directory for fastscape and compile it with an added flag for creating a shared library.    cmake -DBUILD_FASTSCAPELIB_SHARED=ON /path/to/fastscapemake    make2. Compile ASPECT with a flag FASTSCAPE_DIR pointing to the fastscape build folder with the shared library    cmake -DFASTSCAPE_DIR=/path/to/fastscape/build -DDEAL_II_DIR=/path/to/dealii -DCMAKE_BUILD_TYPE=Release /path/to/aspect    make*Note: ASPECT will still compile and install even if a FastScape version is not found. During cmake, it should state whether or not FastScape was found, if it was not you'll need to rerun cmake.*Note: For FastScape visualization add the following line to your .bashrc: export GFORTRAN_CONVERT_UNIT=‘big_endian’Input file for each model (.prm file) shows distinct key parameters:- Model 1 (High crust-high mantle density): Crust density: 3150 kg/m3 Mantle density: 3300 km/m3 Lithosphere thickness: 60 km- Model 2 (Low crust-high mantle density): Crust density: 2900 kg/m3 Mantle density: 3300 km/m3 Lithosphere thickness: 60 km- Model 3 (Thick lithosphere): Crust density: 2900 kg/m3 Mantle density: 3300 km/m3 Lithosphere thickness: 90 km- Model 4 (Low crust-low mantle density): Crust density: 2900 kg/m3 Mantle density: 3200 km/m3 Lithosphere thickness: 60 kmParameters files for all runs used in the study: A Large Igneous Province core complex in the William’s Ridge (Kerguelen Plateau)-Broken Ridge conjugate marginsL.

大陆与大洋环境中的裂谷作用已通过观测分析与数值模型得到了充分研究。然而，大型火成岩省（Large Igneous Province, LIP）环境下的裂谷演化相关观测资料匮乏，且缺乏对应的数值模拟研究，使得学界对裂谷力学机制的全面理解仍有待完善。本数据集包含用于构建数值模型的输入文件，用以展示大型火成岩省环境下裂谷作用的热-力学演化过程，研究案例聚焦于威廉姆斯脊-破碎脊（William's Ridge-Broken Ridge）。

本研究的模型运行基于dealii 9.3.0。相关ASPECT版本可通过以下链接获取：https://github.com/EstherHeck/aspect/tree/fastscape_update_again_erosional_base_level-undo2780-before-rebase-on13mai22-Kais-and-ZhiChens-Version；FastScape版本可通过以下链接获取：https://github.com/Djneu/fastscapelib-fortran。

安装带FastScape的ASPECT版本步骤如下：
1. 为FastScape创建构建目录，并添加编译标志以生成共享库：
cmake -DBUILD_FASTSCAPELIB_SHARED=ON /path/to/fastscape
make
make install
2. 编译ASPECT时需指定FASTSCAPE_DIR标志，指向包含共享库的FastScape构建目录：
cmake -DFASTSCAPE_DIR=/path/to/fastscape/build -DDEAL_II_DIR=/path/to/dealii -DCMAKE_BUILD_TYPE=Release /path/to/aspect
make

*注意：即便未检测到FastScape，ASPECT仍可完成编译与安装。cmake执行过程中会输出FastScape是否被成功检测的提示，若未检测到则需重新运行cmake命令。*
*注意：若需实现FastScape可视化，请在.bashrc文件中添加如下环境变量：export GFORTRAN_CONVERT_UNIT='big_endian'*
