    2019-2-1 · Although diamond is composed primarily of carbon, it cannot be carbon-dated since the half-life of carbon is too short (atmospheric 14 C decays to 14 N with a half-life of only 5,700 years) to be useful for any geological material such as diamond that typically has ages on the order of millions to billions of years. Diamonds also do not contain ...

    The success of geological carbon storage depends on the assurance of a permanent confinement of the injected CO2 in the storage formation at depth. One of the critical elements of the safekeeping of CO2 is the sealing capacity of the caprock overlying the storage formation, despite faults and/or fractures, which may occur in it.

    Given these isotope fractionations, it is calculated that a volume of 0.4 · 106–0.8 · 106 Km3 of a mono-mineral assemblage of kainite or carnallite needs to precipitate in order to change seawater δ26Mg by only 0.1‰. This huge volume is by far larger than the volume of these minerals known to date in the global geological record.
