Abstract:
This map is one in a series of 1:500,000-scale geologic
maps initiated by the National Aeronautics and Space
Administration to investigate areas of particular
scientific interest on Mars. Kasei Valles make up one of
the largest systems of outflow channels on Mars and were a
major contributor of water to Chryse Planitita. The walls
and floors of the Kasei channels are terraced and grooved,
closely resembling the channeled scablands of eastern
Washington State that were formed by catastrophic floods
probably lasting no more than a few days (Baker and Milton,
1974; Baker and Kochel, 1979). Evidence obtained from
previous geologic mapping of parts of Kasei Valles (Chapman
and Scott, 1989) was not conclusive as to whether water
levels varied markedly during a single flood and erosional
event or whether flooding was episodic and marked by
intermittent periods of scouring. This problem-whether one
or several flood episodes occurred within individual water
courses-has been a continuing issure in studies of Martian
channel formation (Greeley an others, 1977). Recent larage
scale geologic mapping (Tanaka and Chapman, 1990) of
Mangala Valles, another large outflow channel system in the
Memnonia region of Mars, shows deposits of two periods of
flooding; the deposits are seperated stratigraphically by a
lava flow. In areas around the Chryse basin, geologic
studies indicate that more than one episode of channel
formation occurred or, less likely, that flooding was
episodic in Kasei Valles and probably occurred over
protracted time intervals throughout the Hesperian period
an possibly in the Early to Middle Amazonian. The
map shows the geology of part of the south branch of Kasei
Valles where this large outflow channel emptied into
Chrysia Planitia. The geology is compiled on two
1:500,00-scale photomosaics made form Viking images with
resolutions generallly less thatn 50 m/pixel.
