单词	mascon
释义	mascon /ˈmaskɒn / noun A concentration of denser material below the surface of the moon or other body, causing a local increase in gravitational pull.Researchers spotted a mass concentration, which they call a mascon — dense stuff that welled up from the mantle, likely in an impact.... It has been argued that the mascon gravitational anomalies do not necessarily imply departure from isostacy. The negative correlation between the topography and gravitational potential of the mascons suggests that they are dynamically supported. Origin 1960s: from mas(s) con(centration).
