Molar-tooth structure is a synsedimentary, combined deformation and early diagenetic feature occurring in calcareous strata of mainly Precambrian age. It consists of arrays of closely spaced, sharply defined, upright veins , and subordinate horizontal sheets and spheroids composed of calcite microspar . Veins are vertically to obliquely oriented, discontinuous, typically strongly squashed or crumpled, and often brecciated.
