The majority are small with distinct, prismatic zircon shape and are generally severely fractured. A second group of grains are very small and anhedral. The concordia diagram shows a large scatter, indicating that the zircon population is highly heterogeneous. A discordia is calculated from fractions 2, 3, 4 and 5, giving intercept ages of 2055 ±130 and 445 ±230 Ma, and an MSWD of 43. SIMS data (6 points) have produced a different analytical picture, where data show little scatter, and fit a discordia that yields a relatively well-constrained event at c. 1770 Ma, and near concordant ages of c. 1790 Ma. An averaged 207Pb/206Pb age for the concordant spots 1, 2 and 5a yields 1781 ±10 Ma Martinsson et al 2018a Martinsson, O., Bergman, S., Persson, P.O., Schöberg, H., Billström, K. & Shumlyanskyy, L., 2018: Stratigraphy and ages of Palaeoproterozoic metavolcanic and metasedimentary rocks at Käymäjärvi, northern Sweden.

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.

A younger group of CL-dark structurless (?) zircons with variable Th/U ratios was interpreted to date a metamorphic event at 1916±5 Ma (n = 14, MSWD is 1.8). Two low Th/U CL-bright zircon analyses gave even younger apparent 207Pb/206Pb ages at 1895 +/-17 Ma and 1872 +/-34 Ma (1s).

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. Excluding three youngest zircons, the 207Pb/206Pb-weighted mean age of the 13 youngest analyses is Hellström et al 2018 Hellström, F.A., Kumpulainen, R., Jönsson, C., Thomsen, T.B., Huhma, H. & Martinsson, O., 2018: Age and lithostratigraphy of Svecofennian volcanosedimentary rocks at Masugnsbyn, northernmost Sweden – host rocks to Zn-Pb-Cu- and Cu ±Au sulphide mineralisations.

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). Although poorly constrained and based on only a few analyses it is suggested that the igneous crystallisation age of the granite is dated at c. 1.88 Ga.

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).

Oscillatory zoned with only subordinate disturbance of the zonation pattern, thin irregular BSE-dark porous internal alteration domains commonly developed along the crystal edges or along internal cracks. Weakly zoned or unzoned (BSE) domains define a tight age cluster that shows no indication of ancient Pb-loss. These analyses give a weighted average 207Pb/206Pb age of 1939 ± 3 Ma (MSWD = 0.98, probability = 0.45). Some of the data points are slightly discordant (spread in 206Pb/238U ratios) which disqualify calculation of a concordia age.

A calculated discordia line through all 24 analyses gave an upper intercept at 1348 ± 14 Ma, which is identical to the weighted average age.

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.

The mylonitic texture of the rock combined with absence of a grain size versus age correlation for the white mica grain size fractions suggests that the end of amphibolite facies ductile deformation is dated.

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.

There are also elongated, ovoid, spherical to fragmental zircon. BSE-homogenous dark or with white and dark BSE patches.PbC-corrected data yields an upper intercept of 1778±22 Ma and a lower intercept age of 414±17 Ma (MSWD 10.2, n = 45). Two analyses are concordant and PbC-corrected data yields a weighted mean age of 1833±18 Ma (MSWD 0.74).

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. In total there are 31 analyses of which seven respectively six analyses are concordant in uncorrected respectively corrected data.

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.
