WebClays minerals occur in sediments formed by the weathering of rocks and are another family of silicate minerals with a tetrahedral sheet structure. Clay minerals form a complex family and are an important component of many sedimentary rocks. Other sheet silicates include serpentine and chlorite, found in metamorphic rocks. Clay minerals are ... WebThe structure of brucite consists of sheets of MgO 6 octahedra lying in the plane of the x and y axes. The MgO 6 octahedra have H atoms at each apex ( Fig. 1 A ). The layers are stacked so that the H atoms in one layer are opposite the space between three H atoms in the succeeding layer without significant bonding between the layers.
