Geologic map of the Syrtis Major Quadrangle of Mars Geologic map of the Syrtis Major Quadrangle of Mars

The Syrtis Major quadrangle is located in the equatorial belt of Mars across the boundary between the cratered plateau region to the south and west and the northern lowland plains. The cratered plateau is part of the northern extension of cratered highlands, which generally stands at altitudes greater than 4 km. The southeastern part of the quadrangle is dominated by eastward-sloping...

Geologic map of the west side of the Moon Geologic map of the west side of the Moon

The west limb region of the Moon consists of highly cratered terra rising 5 km or more above the mare of Oceanus Procellarum and most of the lunar near side. Crustal material in this area of large basins and craters has been redistributed repeatedly by giant impacts. The early historical record of these events is apparently preserved in a complex of interlayered breccias, which may be...

Geology of the Santa Monica and San Pedro basins, California continental borderland Geology of the Santa Monica and San Pedro basins, California continental borderland

In the period 1964 to 1974, the U.S. Geological Survey conducted various seismic reflection and rock-sampling cruises in the continental borderland of southern California. This map report, on two near-shore basins, the Santa Monica and the San Pedro (sheet 1, figs. 1 and 2), is based on data obtained during these surveys. The tracklines in these basins are shown on sheet 1, fig. 3. H. G...
