Abstract
This paper presents the results of the geological and chemical research of Diatomaceous earth in the deposit Veshje near by Negotino.
The deposit - Veshje belongs to Tikvesh basin which is situated in the central part of Vardar zone. This rich and numerical representation of diatomaceous flora and conditions that were present in the upper lake basin during Pliocene are actually the major factors for the formation of productive layer of Diatomaceous earth. Productive diatomaceous horizon appears in a form of a layer, with a length of 1-2 km and a thickness of 0,6 - 1,25 m, tending to form a spike towards the peripheral parts of the basin. Immediate layers above and below of the productive horizon are the andesite tuffs and agglomerations.
Based on chemical analyzes made done on Diatomaceous earth from Veshje, it resulted in the following content: SiO2 - 78.40 %, Al2O3 - 6.40 % CaO - 2.20% and Fe2O3 - 2.60 %. Under this structure, Diatomaceous earth is a quality mineral resource which can be applied for filtration, thermal insulation and many other uses in industry and construction.
