Scientific paper

Tesserae boundary characteristics and density of impact craters on tesserae (complex ridged terrain of tectonic origin) as well as on the remainder of the planet (mostly volcanic plains) were studied using the Magellan images for about 96% of the surface of Venus. About 97% of the total length of tesserae boundary evidence plains material embayment into tesseral massifs. This suggests that tesserae are older than their surroundings. The density of large (D greater than 16 km) impact craters on tessera is higher by a factor of about 1.4 than on the remainder of the planet. That means that for the tesseral craters the retention age is larger than the age of the plains. This fact is in agreement with the fact that tesserae in majority are embayed by the surrounding volcanic plains. The density of small (D less than 16 km) impact craters on tesserae is lower than on the remainder of the planetary surface, evidently an observational bias caused by a difficulty in recognizing the small craters on rough tesseral terrain. The absence of recognizable tectonic deformations in most of the large on-tessera craters means that during the period of craters emplacement most of the tesserae studied were tectonically stable and did not undergo a noticeable degree of deformation.
