Marble study

For marble provenance studies, the most successful technique seems to be the measurement, through mass spectrometry, of the abundance ratios of the stable isotopes of carbon and oxygen (116). However, no single technique appears to provide unequivocal results, especially in cases such as the different Mediterranean sources, and a combination is often necessary to arrive at an approximate place of origin (117).

Figure 8. A Mg vs. 5 Mg plot of limestone, dolostone, and marble samples (data from Galy et al. 2002) compared with a sample of foraminifera of various species (Chang et al. 2003) and seawater (Chang et al. 2003, this study). The broadly horizontal trend of the carbonates at elevated A Mg suggests a component of equilibrium fractionation relative to seawater. The P value derived by regression of these 5 Mg and 5 Mg data is within the range for equilibrium fractionation and statistically distinguishable from purely kinetic fractionation.

I disciplined myself, in those days, getting up at 4 30 A.M. to study books on cybernetics, and insisting on boring my fellow residents with a ccmputer model I had made from bendable soda straws, tinker toy parts, paper clips and marbles. Success and failure were equally stimulating and nothing seemed to faze me for long. I was young, carefree and passionate. 

Suppose the box has a false bottom and someone under the table is changing the marbles in the box. Is this relevant to the concept of an analytic study as opposed to an enumerative study ... 

Isotopic studies and comparison of marbles in the Sambagawa metamorphic belt, central Shikoku, Japan and marbles from the Kumdy-Kol area of Kokchetav Massif, North Kazakhstan... 

Marbles occur in many regional and contact metamorphic terrains in the world and isotopic studies of marbles have been carried out and report by many authors. Carbon isotope studies of marbles can be useful, in many cases, to reveal the origin of carbonates because differences in carbon isotope ratios of marbles can reflect different origins. 

The Sambagawa metamorphic belt of central Shikoku is part of the intermediate high-pressure metamorphic belt in Japan. Marbles examined in this study were collected from Iratsu (samples Ta-01 Ta-14) and Tonaru (samples Ta-15 Ta16), as well as and epidote amphibolites masses from each area representing metamorphosed layered gabbro... 

A critical issue is the extent to which the isotope composition of a metamorphic rock is modified by a fluid phase. Volatilization reactions leave an isotope signature greatly different from that produced when fluid-rock interaction accompanies mineral-fluid reaction. Changes of 5-10%c are a strong indication that fluid-rock interaction rather than volatilization reactions occurred during the metamorphic event. Coupled 0-C depletions are seen in many metamorphic systems involving carbonate rocks. Figure 3.50 summarizes results from 28 studies of marble mostly...
