Sobre IBD

Dyki lamprofitowe charakteryzują się powszechnymi strukturami skrzynkowymi (pułapki fizyczne) wypełnionymi napływającą mineralizacją, a ich skalenie i miki są stosunkowo zmienione do minerałów ilastych (pułapki chemiczne). Występują trzy etapy: pierwszy (etap wysokiej temperatury), który charakteryzuje się tworzeniem się rodzimego Au i Ag związanego z pierwotnymi minerałami siarczkowymi, takimi jak piryt, galena, kasyteryt, litargit i arsenopiryt. Drugi etap (w niższej temperaturze) charakteryzuje się tworzeniem wtórnych minerałów siarczkowych. Trzeci etap związany jest z wapnieniem powstałym po utlenieniu (zmiana supergeniczna) i charakteryzuje się tworzeniem kalcytu i minerałów uranu.

    Why an awareness of Earth’s temporal rhythms is critical to our planetary survivalFew of us have any conception of the enormous timescales in our planet’s long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. The passage of nine days, which is how long a drop of water typically stays in Earth’s atmosphere, is somet...

    Why a warmer climate may be humanity’s longest-lasting legacyThe human impact on Earth’s climate is often treated as a hundred-year issue lasting as far into the future as 2100, the year in which most climate projections cease. In The Long Thaw, David Archer, one of the world’s leading climatologists, reveals the hard truth that these changes in climate will be 'locked in,' ess...
