The MSWD value is 29 suggesting a significant heterogeneity among the fractions used in the regression. A single titanite fraction gives an age of c. 1.81 Ga, probably reflects the peak of the youngest high T metamorphic event in the area.

Altogether, 149 zircon analyses were carried out. 104 of these were less than 5% discordant and selected for plotting in the age distribution diagram. The zircon age population is dominated by 2.15-1.90 Ga Karelian-Svecofennian ages (66% of the entire zircon population) and 2.95-2.62 Ga Archaean ages (30%). Two analyses have ages at 2.44 & 2.50 Ga (2%) and a single analysis is dated at approximately 3.29 Ga (1%). The younger age group peaks at 2.04 Ga, with a smaller peak at 1.92 Ga. The nine youngest zircons give a 207Pb/206Pb-weighted mean age of 1911 ±10 Ma (MSWD = 0.14, probability = 0.997), suggesting a maximum depositional age of Pahakurkio group sedimentary rocks of c. 1.91 Ga.

Because of the discordance, no concordia age can be calculated. A discordia line through all 14 points yields an upper intercept age of 1793±6 Ma, with a lower intercept at 379±250 Ma, and MSWD 2.9. Excluding the somewhat deviating point no. 14, which has the lowest 207Pb/206Pb age and markedly higher U and Pb concentrations than the other points, a weighted average 207Pb/206Pb age of 1792±4 Ma (2s, MSWD 2.7, n = 13) is calculated.

BSE images show variable internal structures, many grains showing oscillatory or patchy zonation. Some grains have clearly xenocrystic cores. Microcracks in the zircons are common and many grains show BSE-dark, probably metamict domains. 149 zircon analyses were carried out. 92 analyses of these were less than 5% discordant and selected for plotting in the age distribution diagram. The zircon age population is dominated by 2.15-1.86 Ga ages (81%) and 2.96-2.55 Ga ages (11%), with a few analyses outside these ranges. Two analyses have ages of c. 3.38 and 3.58 Ga (2%), three analyses of 2.52-2.47 Ga (3%) and three of c. 1.85-1.84 and 1.80 Ga (3%). The significance of young ages is uncertain, but they may reflect secondary partial resetting of the U-Pb isotopic system, or lab contamination.

BSE-imaging shows an internal oscillatory zonation in the zircon, and textural older cores are evident in some grains. One analysis located in an textural older core, records an older age of c. 1.91 Ga, compared with the other analyses, and is interpreted as inherited. Eight analyses are concordant and record a concordia age of 1887 ±5 Ma (2s, MSWD of concord. + equiv.=1.3, probability (concord. + equiv.)=0.19, n=8).

BSE-images of the zircon show a homogenous colour level and CL-imaging a mottled appearance of the zircon (Fig. 129). The 13 analyses are all low in uranium, 73-131 ppm, and show rather low Th/U ratios, 0.08-0.20. Four analyses (5, 16, 22, 23) record high values of common lead (f206=0.38-1.22 %) and are 6.9-11.8 % discordant. Excluding also two 3.7% and 3.9 % reversely discordant analyses (43, 21), the remaining eight analyses give a concordia age at 1 777 ± 10 Ma (95 % confidence, MSWD of concordance = 1.3, Probability of concordance = 0.26, n =8). Including the two weakly reversely discordant analyses, a weighted average 207Pb/206Pb age is calculated at 1773 ± 7 Ma. The odd internal texture and low Th/U ratios of the zircon may question the magmatic interpretation of the age.

One of these analyses, No. 35, is slightly older than the others, possibly containing an inherited component and excluding that analysis the weighted average 207Pb/206Pb age is calculated at 1875 ± 9 Ma (2s, MSWD = 0.013, probability = 0.91, n = 2).

Analyses that are less than 3.0 % discordant give a concordia age of 1784 ± 4 Ma (MSWD = 4.7 probability of concordance = 0.031) and a 207Pb/206Pb weighted mean age of 1 782 ± 5 Ma (MSWD = 0.64, probability = 0.82). The concordant analyses from one grain (4, 4b) show a much older age, with apparent 207Pb/206Pb ages at about 1.98 Ga and this zircon is probably inherited.

However, obvious from the concordia diagram, one of the analyses (4r2) has a slightly older age (207Pb/206Pb age at 1895 ±6 Ma, 2s) compared to the other analyses, possibly due to mixing with an older age component. Excluding that analysis will lower the concordia age to 1878 ±4 Ma (MSWD of concordance and equivalence = 0.15, probability of concordance = 0.69, 2s, n=3), which is identical to the weighted 207Pb/206 Pb mean age at 1878 ±4 Ma (MSWD = 0.27, probability = 0.76).

Including also a weakly discordant analysis (2a), the weighted average 207Pb/206Pb age is calculated at 2668 ± 3 Ma (2s, MSWD = 1.13, probability = 0.34). One inner core analysis (3a) yielded a lower age at c. 2.56 Ga and was excluded from the above age calculations. The reason for this lower age is unclear. A CL-dark, rim analysis of the same grain recorded an older age of c. 2.66 Ga. The U concentration of the 2.67 Ga zircons is 108-720 ppm, and and Th/U-ratio is 0.33-0.92.

A calculated discordia line through all 24 analyses gave an upper intercept at 1348 ± 14 Ma, which is identical to the weighted average age. The lower intercept at 833 ± 170 Ma may not be meaningful due to large uncertainty.

Dates obtained from the CL-bright zones range between ca 1400 and 960 Ma and may reflect mixing of differing amounts of two zircon components. A discordia line through thirteen points has an upper intercept at 1367 ± 32 Ma and lower intercept at 920 ± 51 Ma (2s, MSWD = 1.4); The interpretation of the data for CL-bright zircon is that the upper intercept represents the oscillatory zoned zircon component, whereas the lower intercept indicates the age of the CL-bright zones. Fracturing and crack-sealing with CL-bright zircon occurred during the Sveconorwegian deformation.

The intrepretation is that the sector zoned CL-dark zircon rims formed during partial melting in the Tjärnesjö intrusion during Sveconorwegian metamorphism.

Obtained ages show a large variation. Spots with low discordance show 207Pb/206Pb age populations groups: 2.7-2.2 Ga (n=6); 2.0-1.9 Ga (main group), 1.81-1.80 (n=2) Ga and 1.76-1.74 Ga (n=2). The younger (207Pb/206Pb) population, close to 1.8 Ga, is indicated for euhedral- subhedral grains, whereas anhedral and rounded grains yielded two pre-Svecofennian age populations. It was suggested that anhedral zircons have a detrital origin and that the quartz-rich host rock is a xenolith belonging to the c. 1.88–1.86 Ga Västervik quartzite formation. The euhedral-subhedral zircons in the 1.80–1.77 Ga interval is interpreted to be newly formed in the quartzite as a result of its incorporation as a xenolith in the TIB 1a magma and associated tectonic and hydrothermal processes.

The four oldest upper intercept concordant analyses give a wtd. 207Pb/206Pb mean age of 1795±20 Ma (MSWD = 2.0) for common Pb uncorrected data and 1784±10 Ma (MSWD = 0.62) for PbC corrected data. The uncorrected age was favoured as PbC corrections could lead to analytical overcompensation in this case with relatively low common Pb signatures of the zircons.

alder.3007 3007 STB220030A n6607 Norrmalm Rhyolite Metarhyolite with grantic veins. Svecokarelian Orogen Bergslagen lithotectonic unit Supracrustal rock c. 1.96-1.86 Ga (Svecofennian) Nordsim, Swedish Museum of Natural History, Stockholm 1 U-Pb SIMS Zircon Concordant age 1873.0 6.0 6.0 6.0 10 2 5 Magmatic age Not classified Most zircons in the sample are metamict and recorded ages between c 1.87 and 1.80 Ga. The oldest ages are from two concordant analyses in a single, less metamict crystal with a concordia age of 1873±6 Ma, and a weighted 207Pb/206Pb mean age of 1864±3 Ma (MSWD 1,1). This age is suggested to possibly represent the igneous crystallisation age of the rhyolite, whereas younger ages may result from a later metamorphic event. More and better analyses are needed to better constrain and evaluate the ages.

Five analyses was excluded from age calculation due to high values of common lead or discordance. Remanining seven analyses give a concordia age of 1891,9 ± 3,7 Ma (MSWD = 3,5) and a 207Pb/206Pb weighted age of 1893 ± 2 Ma (MSWD = 7).
