Geoscience is a multi-disciplinary journal aimed at bringing together top-quality research across the entire spectrum of the Earth Sciences along with relevant work in related areas. Geosciences Journal opens a new era for the publication of geoscientific research articles in English, covering geology, geophysics, geochemistry, paleontology, structural geology, mineralogy, petrology, stratigraphy, sedimentology, environmental geology, economic geology, petroleum geology, hydrogeology, remote sensing and planetary geology.
