[1] Although Mars is currently not tectonically active, it may have experienced plate tectonics early in its history. The southern hemisphere of Mars possesses a thick crust which probably renders the lithosphere positively buoyant. In this paper we present numerical and scaling arguments which show that if the area of positively buoyant lithosphere grows beyond a critical fraction ( 50% for Ma...

The Earth is likely to have acquired most of its water during accretion. Internal heat of planetesimals by short-lived radioisotopes would have caused some water loss, but impacts into planetesimals were insufficiently energetic to produce further drying. Water is thought to be critical for the development of plate tectonics, because it lowers viscosities in the asthenosphere, enabling subducti...

Archaeologists and historians working on topics such as agricultural technology, resource distribution, settlement patterns, raw materials procurement, artifact analysis and natural disasters are automatically involved in geological questions. The geologic history of the Japanese Islands is, therefore, of basic importance to our enquiries, but those interests are poorly served by the current li...

We present a set of algorithms that recovers detailed building surface structures from large sets of urban images containing severe occlusions and lighting variations. An iterative weighted-average algorithm is introduced to recover high-quality consensus facade texture. 2D and 3D methods are combined to extract microstructures, facilitating urban model refinement and visualization.
