Summary

The Systematic mapping of lava flow units in the Tharsis region has been compiled into a series of 16 maps at 1:2,000,000 scale. This work provides information on the sources and areal extent of the lava flows, on their eruptive sequences and relative ages, and on relations between the flows and geologic structure in the largest, most active tectonic and volcanic province on Mars. Some of the maps were made from controlled Viking photomosaics published as quarter quadrangles in the Atlas of Mars Topographic Series (U.S. Geological Survey, 1979) and tied to the Viking control net. Where these photomosaics were not available, larger scale catalog photomosaics tied to the Mariner 9 control net were used. These maps were subsequently reduced [...]

Purpose

Digitized 1:2,000,000-scale geologic map of the MC2SE - Diacria Quadrangle of the Mars. The scanned map sheet was imported into ArcMap and georeferenced to the more current Thermal Emission Imaging System (THEMIS) images from the 2001 Mars Odyssey orbiter mission. Contacts and geologic units were digitized and attributed based on type and unit name.
