Техас и Антарктида — казалось бы, между ними нет абсолютно ничего общего. Однако, как установили исследователи из Университета штата Калифорния, что в Бейкерсфилде, общего достаточно: 1,1 миллиарда лет назад оба региона были частью суперконтинента Родинии, объединявшей Северную Америку и Антарктиду и распавшейся 750 миллионов лет назад...
Граница континентов проходила как раз по территории современного Техаса, а также по антарктической Земле Котса. В рамках исследования ученые под руководством профессора Стейси Леви провели анализ магматических пород, собранных в горах Франклина (штат Техас), на полуострове Кивино (штат Мичиган) и на Земле Котса (запад Антарктиды). Оказалось, что соотношение изотопов свинца в образцах практически одинаково. Так что, находясь в Техасе, имейте в виду: этот жаркий штат похож на скованную льдами Антарктику куда больше, чем кажется.

Texas and Antarctica - it would seem, between them there is absolutely nothing in common. However, as established researchers from the University of California, in Bakersfield, common enough: 1.1 billion years ago, both regions were part of the supercontinent Rodinia, which united North America and Antarctica and disintegrated 750 million years ago.
The boundary of the continents took place just on the territory of modern Texas, as well as on Antarctic Earth Coats. In the study, researchers led by Professor Stacy Levy conducted an analysis of magmatic rocks collected in the mountains of Franklin (Texas), on the peninsula Kivinen (Michigan) and Coats Land (West Antarctica). It was found that the ratio of lead isotopes in the samples is almost the same. So, being in Texas, keep in mind that hot state like icebound Antarctic where more than it seems.
