| Description: | 1.6 km. south of Tarbat Ness, Ross & Cromarty. Concretions in calcareous sandstone of the Middle Old Red Sandstone. These large roughly spherical sedimentary structures are hard compact masses of mineral matter formed by precipitation from an aqueous solution around a nucleus. They are usually formed of a single sedimentary mineral that occurs as a minor constituent of the rock. Most concretions form during diagenesis i.e. when the rock was being formed after sedimentary deposition. |
