On a plot of {13}C $\delta$^{13}C  versus {18}O $\delta${18}O  the restricted range of isotopic composition of the vein is highlighted with {13}C $\delta${13}C  and {18}O $\delta${18}O  values between +1.5 to +3.7‰_{VPDB} and -7 to -10‰_{VPDB} respectively, Figure 6(a). There is a degree of structure in the data but given the limited data set it is hard to determine the significance of this. For the most part {18}O $\delta${18}O  and {13}C $\delta${13}C  are decoupled with a horizontal band of data covering a range of {18}O $\delta${18}O  values between -8 and -10‰_{VPDB} and little or no variation in {13}C $\delta${13}C  at a value close to +3.5‰_{VPDB}. A subset of the data with a positive 1:1 correlation between {13}C $\delta${13}C  and {18}O $\delta${18}O  and an outlier  of three points with relatively high {18}O $\delta${18}O  values (-7 to -8‰_{VPDB}) and low {13}C $\delta${13}C  values (1.5 to 2‰_{VPDB})is evident. As suggested by the data plotted in Figure 5 there is a marked inverse covariation between T(_{47}) T($\Delta$_{47})  and {18)O. $\delta${18}O.  At the lowest measured temperatures of 30-45{o}C 30-45^{o}C  the {18}O $\delta${18}O  value of the calcite is between -7 and -8‰_{VPDB}. This decreases towards -10‰_{VPDB} at the highest temperatures.
