A Holocene Sedimentary Record from Lake Silvana, SE Brazil
Müller, German / Rodrigues-Filho, Saulo
Mineralogical-sedimentological and geochemical investigations in combination with pollen data of a 12.7-m-long dated sediment core from Lake Silvana, SE Brazil, permit the reconstruction of the climatic history over the past 10, 000 years. The lowermost section (I) reflects a coarse paleosol-type sediment with abundant plant debris and rootlets, pollen indicates grassland vegetation. Section II represents fine-grained lake sediments, pollen in...
