These tabulated radiohalos data were then plotted by hand on a graph with the conventional ages of the rock units in millions of years from 0-3500 Ma (x-axis) versus the number of radiohalos per slide (y-axis) in each rock unit (Fig. 5). Granites were distinguished from metamorphic rocks by different symbols. It should immediately be evident from Table 1 and Fig. 5 that many samples cluster within the shorter conventional time range of the Phanerozoic (0-539 Ma) compared with the wider spread of the Precambrian (>539 Ma) samples. Thus, for ease of identifying any trends in the radiohalos data for the Phanerozoic rock units, those data were hand plotted on a similar graph with only a conventional age spread of 0-600 Ma on the enlarged x-axis (Fig. 6). V. DISCUSSION It is assumed for the purposes of this study that the conventional ages are valid within the conventional paradigm, but they are used here only to identify the relative positions of the rock units in the geologic record. While it has been well-demonstrated that there are numerous significant problems with each of the long-age radioactive dating methods that preclude the obtained ages from being absolute ages (Snelling 2000a), there is still a systematic trend in conventionallypublished radioactive ages of rocks according to those rocks’ relative positions in the geologic record. In other words, the oldest-aged rocks are found at the observationally-established bases of local rock sequences, and the observationally-established overlying and intruded rocks units decrease in age according to the relative order of formation of the rock units (Snelling 2005b, c, Vardiman et al. 2005). If it is established that there was a pulse of five-orders-of-magnitude accelerated radioactive decay with accompanying heat during the Flood (Vardiman et al. 2005), then all pre-Flood and Creation Week rocks would have been affected by that pulse of accelerated radioactive decay with accompanying heat. And since it has been demonstrated observationally that radiohalos are annealed (wiped out) above a temperature of only 150°C (Laney and Laughlin 1981), then any radiohalos in them produced before the Flood would have been annealed by that pulse of accelerated radioactive decay with accompanying heat. Thus, the radiohalos we observe today in preFlood and Creation Week rocks would have been produced in them during the Flood after they had again cooled below150°C. This needs to be kept in mind when interpreting the radiohalos data tabulated in this study (Tables 1 and 2). From the radiohalos frequency data plotted in Fig. 5 it should be immediately evident that: (1) There is clear difference between the radiohalos frequencies in Phanerozoic (0-539 Ma) granites compared to Precambrian (>539 Ma) granites. Indeed, radiohalos frequencies rise dramatically from the average range of about 0-15 radiohalos per slide in most Phanerozoic and all Precambrian granites to a range of 25-64 radiohalos per slide in some Phanerozoic granites, for example, the Mole Granite, Land’s Table 2 continued Dyrkorn Gneiss Sunnmøre, Norway Archean 1 (50) 24 0 7 5 0 0.72 0.62 4.8:1 -- 3.4:1 -- Gneiss Ilomantsi, Finland Archean 1 (50) 83 0 0 29 0 2.24 1.66 2.9:1 -- -- -- End Granite, Tinaroo Granite, Bodmin Moor Granite, Alamaden Granite, Strathbogie Granite, Encounter Bay Granite, and the Palmer Granite (Table 1). In contrast, the Precambrian granites have a range of only 0-10 radiohalos per slide. (2) The radiohalos frequency in Phanerozoic and Precambrian regional metamorphics rocks are generally the same range at 0-15 radiohalos per slide, similar to the range of radiohalos frequency in most Phanerozoic and all Precambrian granites. However, whereas the average range of radiohalos frequency in most regional metamorphic rocks is 0-5 radiohalos per slide, there are some regional metamorphic rocks that stand out with a range of 10-15 radiohalos per slide, for example, the Precambrian Vishnu Schist and the Phanerozoic Cooma Metamorphic complex, and the migmatite associated with the Palmer Granite (Table 2). (3) There are lots of “time” gaps in the spread of Precambrian samples, both granites and the regional metamorphic rocks clumping together. In fact, there appears to be some clear groupings, namely, peaks at about 1400-1850 Ma and about 2550-3200 Ma, plus another tiny peak around 600-700 Ma among the Precambrian samples, and then from 0-500 Ma in the Phanerozoic as a whole. Where the timescale for the Phanerozoic has been expanded in Fig. 6, similar observations are evident: (1) The radiohalos frequencies are well above the average 0-15 radiohalos per slide for the granites generally in the Mole Granite (c.33), Land’s End Granite (c.57), Tinaroo Granite (40), Bodmin Moor Granite (c.37), Alamaden Granite (c.38), Strathbogie Granite (c.64), Encounter Bay Granite (c.47), and the Palmer Granite (c.39). (2) The paucity of samples of Phanerozoic regional metamorphic rocks does not permit comparisons between such rock units, the Cooma Metamorphic complex (c.12) and the migmatite associated with the Palmer Granite (c.15) do still stand out at the high end of the 0-15 radiohalos per slide average range as found in most of the Phanerozoic granites. (3) There is also a possible peaking of the Phanerozoic radiohalos frequency data from about 200 Ma to 500 Ma. That corresponds to the Triassic to upper middle Cambrian or primarily the Paleozoic. Furthermore, after a tiny secondary peak in the radiohalos frequency data between about 70 Ma and 130 Ma (essentially the Cretaceous) there are hardly any radiohalos in subsequent granites (Paleogene and Neogene). Of course, it must be recognized that some of these observations could be biased by the spread of sampling. There are some obvious apparent sampling gaps in Figs. 5 and 6 where there are no granites or regional metamorphic rocks plotted. However, these gaps might also represent a lack of granites or regional metamorphic rocks of those apparent ages in the rock record, for example, between 2000 Ma and 2500 Ma, between 500 Ma and 600 Ma, and between 130 SNELLING Radiohalos through earth history 2023 ICC 552
