The specific surface area of Recent sediments of Lake Kinneret was measured and the contributions of various sediment components to it were evaluated. Most of the lake sediments had specific surface areas larger than 100 m 2 g −1 . Average SSA of the sediments is 181.8 ± 59.7 m 2 g −1 , whereas that of the noncarbonate fraction, constituting on the average 54.8 ± 12.3% by weight of the sediment, is 374.6 ± 106.9 m 2 g −1 . Despite their high proportion in the sediment, carbonates contribute only a very small fraction of the specific surface area; clay minerals in the 0–2‐ µ size fraction, particularly smectite, contribute most of it.
