types of features in this study

Lobate lava flows are created when very fluid lavas overflow their
channels or issue from large fissures and then expand laterally.
These flows often cover large distances and may be compared with
flood lavas on Earth and the Moon.  The limiting edge of the flow often
has a sharp drop in height which allows it to be identified by low angle

The edges of lobate lava flows stand out on high resolution photos of Mars
with low angle lighting.
Only about 40% of the photographic coverage of
Mars on GoogleEarth-Mars has the necessary high resolution to resolve
these features.  In spite of their light color, the Martian lavas closely
resemble the characteristics of basalt lava flows on Earth.
