Based on mineral composition and content, shale can be classified into three primary categories, i.e. siliceous shale, carbonaceous shale and calcareous shale [9]. Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time. Shale is a sedimentary rock.Schists, which form under medium-grade metamorphic conditions, contain medium-to-coarse flakes of aligned mica that we can easily see. This photo (Figure 8.28) shows a typical schist. Schists are higher- grade rocks than phyllites, and most form when phyllites are further metamorphosed. Thus, the precursors of schist are shale, slate, and phyllite.Sound experience in fields as Exploration Geology - Ore control - Mineralogy support to metallurgy - Reconcilliation - Reporting (Spanish -English).<br>Management of multicultural teams. <br>Work in remote areas with proven results from initial stages.<br>Ability to train/guide people to meet targets at all levels.<br>Strong HSE background. | Obtén más …30 thg 1, 2018 ...
