Biomicrite.

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 earliest dolomite (Dol1) replaces the precursor micrite-biomicrite Kl unit (Fig. 12A, D). Dol1 is a fine-grained (4–40 μm) dolomicrite which is fabric-retentive and suggests that dolomitization commenced at low temperatures shortly after burial commenced during the early stages of diagenesis.

Carbonaceous sediments and rocks. Carbonaceous sediments and rocks, primarily coal, have been classified in two ways: by rank (content of carbon and caloric value) and by petrographic characteristics. In order of increasing rank, the classes of coal are (1) lignite; (2) subbituminous coal; (3) bituminous coal; and (4) anthracite.

In Karalis, some quarries of biolitite and biomicrite were already exploited during Roman times. It should also be noted that, in addition to the two lithologies, biocalcarenites with intermediate clay contents (2–10%) between biomicrite and biolitite were extracted at the Karalis hills. The different percentages of clay could explain the ...

The Sagada Formation was originally described by Maleterre (1989) as Sagada Limestone for the pre-Miocene limestone in the Cervantes-Bontoc area.
