Recognising that these classes did not encompass all carbonate lithologies, Dunham defined two additional classes within his scheme: BoundstoneRed algae-bearing wackestone-packstone microfacies Red algae are abundant in the rock of the Yamama Formation. The most important of these algae species is the Permocalculus ssp. group, which is the main red algae group preserved as fossils, and most of the red algae belonging to this group are characterized by perforated skeletons.See other industries within the Manufacturing sector: Aerospace Product and Parts Manufacturing , Agriculture, Construction, and Mining Machinery Manufacturing , Alumina and Aluminum Production and Processing , Animal Food Manufacturing , Animal Slaughtering and Processing , Apparel Accessories and Other Apparel Manufacturing , Apparel Knitting Mills , Audio and Video Equipment Manufacturing ...Packstone containing oncoids and micrite coated grains coating siliceous sponge spicules, whole hexactinellid siliceous sponge bodies and echinoid spines from Lower Jurassic middle ramp, Morocco.

Particle size and sorting in limestones can be described using a modified Dunham approach, classifying packstone as grain dominated or mud dominated, depending on the presence or absence of intergrain pore space. To describe particle size and sorting in dolostones, dolomite crystal size must be added to the modified Dunham terminology.

The Ocala Limestone consists of nearly pure limestones and occasional dolostones. It can be subdivided into lower and upper facies on the basis of lithology. The lower member is composed of a white to cream-colored, fine to medium grained, poorly to moderately indurated, very fossiliferous limestone (grainstone and packstone).22.65-24.65 Lithofacies: Arenaceous skeletal packstone and grainstone Depositional texture: Arenaceous skeletal packstone and grainstone Color: Very pale orange (10YR 8/2) and grayish orange (10YR 7/4) Sedimentary structures/textures: Part of a very thickly bedded interval Ichnofabrics: Ichnofabric index 4-5.
