DATA OF GEOCHEMISTRY

 [Analyses A, B, and C have been recalculated from Posokhov (1949)) 



Note.— Posokhov has lumped his data for the hypothetical combinations of Ca, 

 Mg, HCO3, and CO3. The data for these columns have been recalculated on the basis 

 that only CaCCh is involved.

B. Ekibastuz Lake, central Kazakhstan. June 16, 1948. 



C. Lake Tuz, central Kazakhstan. June 16, 1948.

A very small sample of the available data for Japanese 

 waters is presented in tables 45, 46 and 47. Additional 

 information may be found in papers by Hanya (1953a, 

 1953b), Hanya and Sugawara (1950), Iwasaki and 

 Nitta (1954a, 1954b), Iwasaki, Nitta, and Tarutani 

 (1953), Kimura and others (1950), J. Kobayashi 

 (1948, 1951b, 1953, 1957), S. Kobayashi (1954), 

 Miyada (1939), Noguchi (1950), Sugawara and Hanya 

 (1948), Sugihara (1951), Takakura (1955), Yamagata 

 (1954), Yamamoto (1952), and Yoshino (1950). A 

 particularly valuable summary may be found in J. 

 Kobayashi (1960). In Japan, volcanic influence on 

 water chemistry is strong, as indicated by the rather 

 high silica levels in the water. In certain localities 

 the water is very acid. Katanuma-ko, a small crater 

 lake, is among the more acid lake waters of the world, 

 having a pH of 1.7 (Hutchinson, 1957). None of the 

 waters for which reasonably complete analyses arc

E-H are recalculated from Polyakov and Kuznetsov (1940).

available is this acid. But the River Su is rather high 

 in acidity; its sulfuric and hydrochloric acid content 

 comes partly from acid-mine wastes and partly from 

 volcanic gases. The miscellaneous analyses given in 

 table 47 are of interest because of the data they provide 

 for the rarer alkali metals and for zinc and copper.

A few analyses for the humid parts of southeast Asia 

 are given in table 48 and some partial analyses for Sunda 

 lakes are given by Ruttner (1930). The analyses of 

 J. Kobayashi (1959) for the Mae Khong are particularly 

 instructive because analyses for the lower reaches of 

 large rivers in the humid tropics are very scarce. The 

 rivers of Thailand, at least, are not as dilute as such 

 rivers are often supposed to be. There are many data 

 in J. Kobayashi (1959) which are not included here, 

 and they show the strong influence of local geology on 

 the chemistry of Thailand rivers. The rivers of the
