��Description:
��� Abstract:
����� The Borealis region surrounding the north pole of Mercury
����� contains the
����� Goethe Basin, whose diameter of at least 400 km makes it
����� the sixth largest impact basin observed on Mariner 10
����� images (Murray and others, 1974; Strom and others, 1975;
����� Trask and Guest, 1975; Boyce and Grolier, 1977; Strom,
����� 1977, 1979). The west half of the mapped area (between long
����� 100� and 190� W.) is dominated by older craters of c 1 , c
����� 2 , and c 3 ages and by intercrater plains material that
����� lies between and within them. Younger crater materials of c
����� 4 age, intermediate plains material, and small patches of
����� smooth plains material are superposed on all other units.
����� The c 4 crater Verdi, 122 km in diameter, is the largest of
����� the younger craters. Its extensive ejecta blanket and
����� secondary crater field are superposed on plains materials
����� and older craters.
��� Purpose:
��� Supplemental_Information:
����� The east half of the mapped area (between long 0� and 100�
����� W.) is
����� characterized by smooth plains material (Murray and others,
����� 1974; Trask and Strom, 1976). This unit covers vast
����� expanses of Borealis Planitia, a depression about 1,000 km
����� in diameter that has an irregular arcuate west boundary.
����� This depression is located over the site(s) of one or
����� several old impact structures (Trask and Strom, 1976; Boyce
����� and Grolier, 1977; Strom, 1979).
