Abstract: The pronounced depletion of the moderately volatile elements relative to the average solar composition is a characteristic signature in most primitive chondrites and bulk terrestrial planets. The exact cause of the depletion has remained enigmatic. Here I show that the moderately volatile element depletion pattern reveals a clear connection between interstellar dust and the rocky materials of the inner solar system. The inheritance of interstellar materials in the solar system is documented not only by the presence of presolar grains and various isotopic anomalies, but also by the chemical element distribution of inner solar system materials.
