The NASA - Magellan Spacecraft has observed, among many other things, remnant Landslide Deposits apparently resulting from the Collapse of Volcanic Structures. This image, centered at 45,2° South Latitude and 201,4° East Longitude, shows us (what could be) a Collapse Deposit approx. 70 Km (such as about 43,47 miles) across. The bright, highly textured Deposit near the center of the image probably consists of huge Blocks of fractured Volcanic Rock, with many of them as large as several hundred meters across. A remnant of the Volcano itself, which might have been approx. 20 Km (such as about 12,42 miles) across, can be (barely) seen at the center of the frame. The distorted radar appearance of the Volcano is a result of the extremely Steep Slopes which characterize the "scars" from which the Landslide Material originated (---> fell). Furthermore, a field of numerous small Volcanic Domes can also be seen in the Northern Half of the frame. The very bright and extremely well visible irregular Surface Lineaments trending to the North-North/West, could reasonably be Ridges, caused by a Regional (---> just local) Tectonic Deformation of the Upper Layers of the Venusian Crust. This frame (which is an Original NASA - Magellan Spacecraft Radio-Image published on the NASA - Planetary Photojournal with the n. PIA 00263), since it is just a Radio-Image of the Venusian Surface and NOT a real view of it, has been colorized, according to an educated guess carried out by Dr Paolo C. Fienga (LXTT-IPF), in what they could reasonably be its possible Absolute Natural Colors (such as the colors that a human eye would perceive if someone were onboard the NASA - Magellan Spacecraft and, once the thick layer of Venusian Clouds and Fogs is completely overcome, looked down, towards the Surface of Venus itself), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. |
