FERTILIZATION CHANGES CHEMICAL DEFENSE IN NEEDLES OF MATURE NORWAY SPRUCE (PICEA ABIES)



Utilization of Integrated Geophysical Techniques to Delineate the Extraction of Mining Bench of Ornamental Rocks (Marble)

Low yields in ornamental rock mining remain one of the most important problems in this industry.This fact is usually associated with the presence of anisotropies in the rock, which makes it difficult to extract the blocks.An optimised planning of the exploitation, together with an improved geological understanding of the deposit, could increase the
