Sediment analysis, or üledékelemzés in Hungarian, refers to the scientific study of sediments. Sediments are naturally occurring materials that are weathered and separated from the original rock or soil. They are transported by agents such as water, wind, ice, and gravity and are deposited in layers. The analysis of these deposited materials provides valuable insights into past and present environmental conditions, geological processes, and even historical events.

The process of sediment analysis involves several stages, beginning with sample collection from various locations, such as riverbeds, ocean floors, lake bottoms, or even archaeological sites. Once collected, the samples are subjected to a range of laboratory tests. These tests can include physical examination, where grain size, shape, and sorting are assessed. Chemical analysis is also crucial, determining the elemental and mineralogical composition of the sediment. This can reveal information about the source materials, weathering processes, and potential contamination.

Microscopic examination is often employed to identify fossils, pollen grains, or other micro-organisms within the sediment, which can act as indicators of past climates, ecosystems, and water conditions. Radiometric dating techniques may be used to determine the age of the sediment layers, providing a timeline for geological or archaeological events.

The applications of sediment analysis are diverse. In geology, it helps reconstruct past landscapes, understand erosion and deposition rates, and identify mineral resources. In environmental science, it is used to monitor water quality, track pollution, and assess the impact of human activities on aquatic and terrestrial ecosystems. Archaeologists utilize sediment analysis to understand site formation processes, reconstruct past human environments, and date archaeological layers. Paleoclimatologists rely on sediment cores to study past climate change. Overall, üledékelemzés is a fundamental tool for understanding Earth's history and its dynamic environmental processes.
