Abstract (in english)
   We dated seven samples from the northern coast of James Ross Island (Gustav Group, Marambio Group) and four samples from Seymour Island, and obtained 11 sets of the data of FT lengths and ages using zircon crystals extracted from them. As a result, Gustav group from James Ross Island has two potentially clusters of ages having less than 100 Ma and more than 130 Ma. Zircon FT ages from Marambio Group of James Ross Island and Seymour Island are consistently older (ca. 120-200 Ma) than previous group. We estimated time-temperature history using the MonteTrax program for the zircon FT data.
