International Journal of Engineering Geology (IJEG) focuses on papers that cover and come under broad topics and is not limited to a particular aspect:
Sedimentology and Geomorphology - facies analysis, regional sedimentary environments, basin analysis, the process of sedimentation, general palaeogeographic reconstruction, diagenesis. [facies analysis, sequence stratigraphy, basin analysis, paleography, diagenesis, especially in petroleum geology.]
Paleontology - macroevolution, extinctions, biostratigraphy, palaeoecology, functional morphology, biogeography, evolution, taphonomy, ichnology.
Quaternary Geology and Environmental Change - recent climate and sea-level change, Quaternary fossils, glaciations.
Tectonics and Structural Geology - including structural geology, strain analysis, fabrics, global tectonics, experimental deformation, Neotectonics, geophysics.
Geochemistry and Geochronology - stable and unstable isotope studies, major and trace element studies, genetic geochemical modeling, fluid-rock interaction, applied geochemistry.
Metamorphic Geology - regional studies, determination of T/P, fluid composition, crystallization paths, history of burial, and uplift of large metamorphic areas.
Volcanic and Igneous Geology - regional studies of igneous provinces, magma genesis, magma composition, magmatic product, igneous centers, petrological studies and more
