Another reviewer commented that the collection was wayard but too fragmental and complex. Later eruptions produced a pyroclastic cone on top of the original fragmental cone. The design was just an expression of the fragmental feel of gardens. Overlying this is 5 to 6 m of fragmental calcarenite containing abundant crinoid columnals. The dominating rocks are Quaternary fragmental debris and effusive. Fragmental textures include clastic, bioclastic, and pyroclastic. Norton County is a Ca-poor aubrite fragmental breccia. Only a fragmental list of the bishops before the 11th century were preserved. Scientific knowledge about the mammals of the Sevan basin is quite poor and fragmental.
