KUZNETSK ALATAU STRUCTURE IN MIDDLE-LATE CAMBRIAN FROM PALEOMAGNETIC DATA Available to Purchase

We present paleomagnetic data on Middle-Late Cambrian volcanosedimentary rocks from the Zolotoi Kitat and Bateny zones of Kuznetsk Alatau. On the basis of the positive fold test and reversal test it is supposed that the age of the revealed characteristic component of magnetization corresponds to the time of formation of rocks. Analysis of Middle-Late Cambrian pole positions in the Zolotoi Kitat and Bateny zones of Kuznetsk Alatau and pole positions of the same age in adjacent structures of the Altai-Sayan folded area and Siberian Platform suggests that in the Cambrian, the Zolotoi Kitat, Martaiga, and Bateny zones were fragments of a single island arc. Their modern relative position resulted from the 35 ± 12° counter-clockwise rotation of the northern (Zolotoi Kitat-Martaiga) fragment about the southern (Bateny) one. In the Middle-Late Cambrian, the Kuznetsk Alatau paleoisland arc together with the other structures of the Altai-Sayan folded area formed a system of island arcs on the margin of the Siberian continent, within the paleolatitude strip 5–20° S.
