Description:
Abstract:
The west Mangala Valles area merits detailed geologic study
because it contains several small channels whose ages can
be determined relative to geologic units that range in age
from early (Noachian) to late (Amazonian) periods of
Martian history. Because the small channels are of three
ages and channels of each age are of a geomorphic type
unique to that age, their study increases our understanding
of the continuity of fluvial processes in the evoluntionary
history of Mars. For these reasons, part of the area is a
proposed site for a sample-return mission to Mars.
Purpose:
Mars Geology
Supplemental_Information:
The map base is a composite of parts of two Viking
1:500,000-scale photomosaics (U.S. Geological Survey,1985).
These photomosaics are based on high-resolution images
except in the area hat now forms the northwest corner of
the composite, for which only lower resolution images are
available. Because the latter images were acquired at sun
angles opposite these on the high-resolution images, the
"mesa" that appears in this area is actually a depression.
Some map units correspond or are partly equivalent to units
on smaller scale maps (Mutch and Morris, 1979, Scott and
Tanaka, 1986). However, in many places interpretations and
contacts have been revised to reflect information visible
on high-resolution Viking images, geomorphic details on
these images were clarified by spatial filtering (Condit
and Chavez, 1979). The depths of channels, thicknesses of
geologic units, and heights of scarps were obtained in
places using photoclinometric methods of Davis and Scott
(1984). The relative ages of geologic units and geomorphic
features such as small channels and faults were established
by stratigraphic realtions and supported by crater counts.
