Land-Ocean Systems in the Siberian Arctic: Dynamics and History
Table 1 (continued);
Remarks:
* Estimation of error after Boenigk, 1983
v = Z~((p*q)/n)
v = possible range of the real value from the counted value (in %)
Z = Faktor, which depends on how many % of the investigated sample are between max. and min. range of
the confidence interval.
p = %-value of mineral x in heavy mineral spectrum
q = (lOO-p) = %-value of specimen, which is not q
n = sum of counted grains
If Z=2 (95% probability) are 95 of 100 counts of one sample in the estimated range
n. a.** not available; Data from Herrnel 1995, unpubl. thesis
