| Zusammenfassung |
| We present the variation of the earth magnetic field intensity obtained from Neogene and
Quaternary volcanic rocks located in the Central Anatolian plateau. Total of four
hundred and fifty volcanic rocks were sub-sampled in eighteen different sites around
the study region. A modified Thellier method including the Leonhardt protocol
was used to determine paleointensity values. Paleointensity results from ten sites
were accepted according to the confidence criteria . According to first results the
average total paleointensity field values, indicated by F, are 51.797±5.044 μT for site
NK8,NK17,NK18,NK15 with age of 4.4-10.7 my, 51.91±4.651 for site NK4, NK3,
NK12, NK6, NK11, NK14 with age of 0.1-2.6 m.y. The average VDMs (Virtual
Dipol Moments) correspond to 8.39x1022 , 8.92x1022 Am2 for the four Neogene
and six Quaternary rocks sites respectively. Our data were correlated with IAGA
database that were obtained from the surrounding area. The correlation showed that the
paleointensity data from the Central Anatolia plateau considerably agree with the IAGA
data. |
