Diamict Versus Till. Diamict (diamictite when a rock) is a nongenetic umbrella term for any poorly sorted deposit regardless of depositional environment (Figures 1 (c), 1 (d), and 3 (a) ). Man-made concrete is a diamictite. Sliding glaciers produce a wide range of diamicts that contain admixtures of most textural classes ranging from clay to ...The tests have been performed on three biomicrite samples: glauconitic biomicrite, which is a variety of the Pietra Leccese, with a fragment of Cetotheride maxillary (Cetacea - Mysticete); biomicrite with cetacean vertebrae (Scaldiceto); normal biomicrite with part of Psephophorus Poligonus(Chelonide); all the samples date from the Middle ...Wakestone facies. It may be divided into two parts, the upper comprises of micritic and spars biomicrite, porous, contain Algae, Globegrinidae, and highly porous with small fractures and cavities in the middle part.
