DATA REPOSITORY

Figure DR1. Slab (approximately 1
.5 x 1.5 cm) of CMEX3. The lim
estone host is at the bottom
10
and the veins that were the focu
s of this study are at the top.
The first generation of veins is
11
radiaxial cement that is low in the REE and U and high in Sr an
d Pb. Note that above this vein is
12
a scalloped brown layer that is high in La, U, and Pb. This vei
n is cut by small veins that are
13
lower in all of the elements than the radiaxial vein. These sma
ll veins appear to terminate at the
14
overlying blocky calcite and have
similar counts for all of the
mapped elements suggesting that
15
the veins could be related. The
scratches on the two small vein
s are an attempt to sample for ID
16
TIMS. This sampling did not yield enough Pb to get an ID TIMS a
nalysis.

Figure DR2. Inverse isochron plot created in IsoExcel (Ludwig,
2012
)
. The data are from LA
19
ICP-MS referenced to a carbonate standard.

Figure DR3. The opposite side of t
he slab shown in Figure DR1.
Spots are plotted and were
23
analyzed from top to bottom. The best estimate of the age of th
e small veins is shown in the
24
inverse isochron which was created in IsoExcel (Ludwig, 2012).

Figure DR4: Ages of individual spots based on taking the ages f
rom Iolite and correcting to the
29
expected age of the natural car
bonate standard. These samples h
ave similar amounts of common
30
Pb making this calculation reasonable. Although the calculation
is somewhat ad hoc, this diagram
31
shows that the data are very coherent. The points that do not f
all on the average line are those
32
with the lower U/Pb. Graph from IsoExcel (Ludwig, 2012).
