The paper presents the results of gravimetric studies at potassium salt deposit in order to obtain information on development negative engineering-geological processes rock mass caused by subsoil development. A methodology was developed for high-precision monitoring observations, which makes it possible determine change field over time. physico-geological model monitoring, representing a homoge...

We report on laboratory experiments in which we allowed an SNC-derived mineral mix to react with pure water under a simulated Mars atmosphere for 7 months. These experiments were performed at one bar and at three different temperatures in order to simulate the subsurface conditions that most likely exist where liquid water and rock interact on Mars today. The dominant cations dissolved in the s...

We inverse the surface gravity data to recover subsurface 3D density distribution with two strategy. In the first strategy, we assumed wide density model bound for inverting gravity data and In the second strategy, the inversion procedure have been carried out by limited bound density. Wediscretize the earth model into rectangular cells of constant andunidentified density. The number of cells i...
