Because the C and O isotopic composition of pedogenic carbonate reflects the isotopic composition of fluid that it precipitated from the time of their formation (e.g., [5, 6]), pedogenic carbonates have been widely used for reconstructing past environmental conditions.

The use of these different raw materials influences not only final chemical compositions of the resulting glass [1], but also the oxygen isotopic compositions.
[C.sub.3] plant species typically have an isotopic ([delta][sup.13]C) range of values between -25[per thousand] and -35[per thousand] with an average around -27 [+ or -] 2[per thousand]; that is, in every 1,000 atoms there are 27 fewer [sup.13]C atoms than in the international standard Vienna Pee Dee Belemnite (VPDB).

INTRODUCTION: The term Wolf's isotopic response refers to the occurrence of a new skin disorder at the site of another, unrelated and already healed skin disease.
The deposition of carbonaceous sediment in these periods is also suggested by the secular variation in the stable carbon isotopic record (i.e., [sup.13]C/[sup.12]C ratio) of sedimentary carbonate and organic matter, which primarily reflects the ratio of the dissolved C[O.sub.2] in the surface ocean.
