Knowledge of the global rates volcanism is fundamental for modeling Earth, as those closely relate to plate tectonics, crustal growth, mantle dynamics, atmospheric evolution, climate change, and virtually any aspect Earth dynamics. In spite their huge relevance, have remained unknown, hidden within data that appeared disordered, largely fragmented incomplete, reflecting poor preservation small ...

Two major types of volcanic units, older regional plains and younger lobate plains, make up 50% of the surface of Venus and represent different epochs of volcanism. The abundance of impact craters partially embayed from the exterior by each of these two types of units permits the testing of the key points of the model of equilibrium resurfacing. The proportion of craters embayed by the older re...

Introduction: The origin of the large gravity anomalies associated with lunar impact basins, or " mascons " , has been a matter of debate since their discovery at the dawn of the age of lunar exploration. More recently, studies of basin structure have led to a prevailing model for producing the anomalies: super-isostatic uplift of the crust-mantle boundary, frozen in at the time of the basin im...
