 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).

DATA_QUALITY_INFORMATION

 
 
 Attribute_Accuracy:
 Attribute_Accuracy_Report:
 All attributes created during the creation process were
 verified by displaying the lines in both the database and
 the spatial coverage, but no formal tests were performed.
 Logical_Consistency_Report:
 These data are believed to be logically consistent, though
 no tests were performed. Line geometry is topologically clean.
