Siliceous ooze is a type of biogenic pelagic sediment located on the deep ocean floor. Siliceous oozes are the least common of the deep sea sediments, and make up approximately 15% of the ocean floor. [1] Oozes are defined as sediments which contain at least 30% skeletal remains of pelagic microorganisms. [2]
The two primary types of ooze are siliceous, which is composed primarily of silica (SiO 2), and calcareous or carbonate, which is mostly calcium carbonate (CaCO 3). [1] In an area in which biogenous is the dominant sediment type, the composition of microorganisms in that location determines to which category it is classified.
Skeleton fragments from siliceous organisms are subject to recrystallization and cementation. [37] Chert is the main fate of buried siliceous ooze and permanently removes silica from the oceanic silica cycle. The siliceous ooze is eventually subducted under the crust and metamorphosed in the upper mantle. [39]

The Kosovar forests have a national significance and are currently protected by over ten laws. [10] Their area is estimated to be as much as 464,800 hectares (1,148,556 acres), of which 278,880 hectares (689,127 acres) are public property managed by Kosova Forestry Agency and 185,920 hectares (459,418 acres) are privately controlled.
Silicate, or silicic acid (H 4 SiO 4), is an important nutrient in the ocean. Unlike the other major nutrients such as phosphate, nitrate, or ammonium, which are needed by almost all marine plankton, silicate is an essential chemical requirement for very specific biota, including diatoms, radiolaria, silicoflagellates, and siliceous sponges.

The fortress is situated on the eastern part of Gadime e Epërme village. The site was archaeologically investigated during the 1973–1974, which resulted with the documented remains of the Copper Age, respectively the Bubanj Sallkuca–Krivadol culture occupation. Also the fortress was reused during the Late Iron Age.
