| Abstract: | The lithology and mineralogy of almandine seam deposit in sericite chlorite schist in Bilutu of Sonid Zuoqi, Inner Mongolia is studied. The studying shows that the surrounding rock of mineralization is a part of Middle Proterozoic, being similiar to Bainaimiao Group.Almandine being red-brown rhombododecahedron consists of iron, aluminium and silicon,containing trace elements of calcium and magnesium. Almandine originated from regional metamorphism to which magmatic thermal metamorphism superimposed. |
