Lacustrine paleo landforms in lake musters and lake colhue huapi, their genetic relationship with a previous paleolake sarmiento. South-central chubut

The recognition of paleo lake accretion and erosional landforms on the east coast of lake Musters, as well as, on the east coast of the adjacent lake Colhué Huapí and far from lake environment, in the south of cerro Puricelli, at similar altimetric positions allowed genetically relate with a regiona...
