Аннотация: Aquatic palynomorph analysis is widely used for paleooceanological reconstructions. The preparation method used for extraction of aquatic palynomorphs from the sediment includes the treatment with hydrochloric (HCl) and hydrofluoric (HF) acids and sieving. The goal of such processing is to remove the mineral component from the sample and obtain exclusively organic matter. However, insoluble mineral crystals are often retained on the microscopic slides, which complicates microscopic analysis. The origin of such crystals has been determined using electron microscopy. The standard method for the extraction of palynomorphs has been adjusted to eliminate or minimize their occurrence. Ways for the prevention of formation of calcium, potassium, and aluminum fluorides, as well as removal of the residues of quartz and aluminosilicate minerals, were proposed.
