Resum

We investigated the mineral-magnetic behavior of sediments from Laguna Toncek located in the NahuelHuapi National Park, Northern Patagonia, Argentina. Rock magnetic analysis complemented by X-ray diffraction and scanning electron microscopy analysis were carried out on sediment core TON1 to provide insights on the environmental and sedimentary processes controlling the magnetic properties of the sedimentand its paleoclimatic implications. The studies suggest the presence of titano-magnetite with a grain size of∼1–2 µm and a concentration that varies between 0.03 and 0.15%
