Internal processes operating within low-density satellites, although they are poorly understood at present, are extremely significant in determining the scale and type of surface processes and features and the geologic evolution of such satellites. The two Galilean satellites Ganymede and Callisto are examples of such low-density (p < 2) bodies, and they are likely to have undergone a thermal e...

The ground-breaking paper by Strauss et al. (2020), clearly demonstrates that salt tectonics play an even more significant role in the sedimentary and early deformational history of Northern Calcareous Alps (NCA) than previously thought. Their pioneering subsidence analysis illuminates importance time diachronous evacuation diapirism during deposition post-salt carbonate platform time-equivalen...

Coral framework construction and resultant growth fabrics in response to environmental factors were studied in the northern Red Sea, and the Gulfs of Suez and Aqaba. The dependence of growth fabric types on sea-floor topography, oceanography and the ecology of constituent coral species was investigated. Five types of coral frameworks and their growth fabrics were differentiated: Acropora reef f...

Introduction: Over the years, there have been many proposed mechanisms for moon formation, including fission, capture, and coaccretion, but the most popular and ever-evolving model at present is the giant impact origin [1]. The impact origin points to the existence of a hot, young moon, likely with a global magma ocean [2]. The next logical step, based on the mantle cumulate crystallization seq...
