Petrophysics, Density and Magnetic Properties
Description
Petrophysics is about the physical properties of rocks. The properties investigated are mainly the rock's magnetism, density and radiometry. The porosity of rocks has also been investigated, but to a very limited extent. The product Petrophysical Data contains data from both laboratory and field measurements of rock samples from all over Sweden. These data are based on direct measurements or samplings, carried out on exposed bedrock, rock samples or cores. Petrophysical data are used to identify and classify rocks and are important in modelling the earth's geological structure in three dimensions, based on geophysical measurements and other observations. For example, petrophysical data can be used to assess whether deviations in the Earth's magnetic or gravitational field are caused by a deep or superficial rock change. The information also contributes to an understanding of the geological processes that a rock has undergone. Classification and mapping of rock bodies is also done for engineering purposes, where petrophysical data form the basis for volume calculations and assessment of mining methods, but also for decisions on suitability and quality related to infrastructure.
