This paper describes a unifying concept of rupturology proceeding from the essential role of geotectonics and morphotectonics with regard to the evolution of the Earth and its crust.

Beitrag zur Einschätzung des Zustandes der Erdkruste der Mittel-europäischen Senke. (A contribution to the assessment of the state of earth's crust of the Middle-European depression)
Based on investigations on the interruption of the isostatic equilibrium of the earth crust and the horizontal gradients of thicknesses and depths within the Middle-European depression different crustal states could be found out for the GDR part

crust structure and the seismic activity, to the movements of the earth's crust. On the other hand, the movements of the earth's crust are in close relation with the depth structure. This gives ground to reveal the movements and the structure
of the Earth's crust in Bulgaria by studying the relief structure.

Properties and spatial distribution of microbiotic crusts in the Negev Desert
Microbiotic crusts play a crucial role in arid regions where they may serve as useful biomarkers for wind power and wetness duration. This is especially the case on relatively the sand dunes in the Negev Desert where high correlations between
the crust chlorophyll content and the daytime wetness duration were found. When a cluster analysis was performed, 5 types of microbiotic crusts were defined which differed in their physical and biological properties. The spatial distribution of the crusts
, as verified by crust mapping, coincided with the daylight surface duration, which in turn was controlled by topography. It implies that whereas initial physical conditions dictates species composition and thus crust type, the crust type in turn is responsible

Space-time analysis of the structural pattern of continents. The assumed eastward migration of the earth's stress field and its reversal in N-S direction every 400 to 500 million years

is introduced : the eastward displacement of the Pacific basin relative to the Earth's crust. New connotations are also introduced : Pangaea is used for all continent crust, past and present, Tethys and Iapetus are taken as synonymous with the Pacific
The geodynamic concept on the convecting Earth presented in this paper is based on a space-time analysis of the structural pattern of continents. It integrates most of the current version of the plate tectonic model. However a new dynamic aspect

A Mars ventifaktjai

On Mars images taken by spirit the ventifacts surfaces are formed by dark brown or black desert crust presumably of ferrous and manganese origin. Superimposing the dark crust on Mars rocks there is a varnish. Material of the latter generally
is associated with blue-green algae which support life even in most extreme conditions, at least on Earth. - (AM)
