Based on studies on other planets it should be possible to find some lava-buried craters. These faults as well as the possible chocolate tablet boudinage of the area are still studied along the proceeding of the work which also includes other small tesserae. The apparent lack of small impact crater is also a mystery which has to be solved by further studies. One possibility is thattectonic activity has been effective enough to remowe, or deform, most of the small impact craters from highlands and these processes are to identified and addressed in details. Magellan data allow us to interpret planet's tectonics, or how and whyits crustal plates have been deformed, broken, collided and moved, what has been the driving force and which processes were involved.
Structures indicate that the share of asthenospheric effects has been very important.
To explain observed structures a new paradigm of the global tectonics or asthenosphere-lithosphere interactions may be needed. Impact craters and their deformation are used as a test objects for the effectiveness of geologic forces in various environments. Venus images Martian tectonics We have studied Martian local tectonics and volcanism at several locations. Partly this has been performed to find answers to certain geologic problems but we have also located certain areas of interest which can be studied from the future data. The loss of Mars Observer and delay of Mars94 to Mars96 were real setbacks for all interests but we will still pursue studies in order to be ready for the new data when available.
