Carbonado typical gem diamonds. Lead isotope analyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks. Mineral grains included within diamonds have been studied extensively for clues to diamond origin. Some typical diamonds contain inclusions of common mantle minerals such as pyrope and forsterite, but such mantle minerals have not been observed in carbonado. In contrast, some carbonados do contain inclusions of minerals characteristic of the Earth's crust: these inclusions do not necessarily establish formation of the diamonds in the crust, however, because while these obvious crystal inclusions occur
Carbonado (Java) Carbonado (Java) Carbonado is an open source relational database mapping framework, written in Java. Rather than following a typical O/R mapping approach, the relational model is preserved, while still being object-oriented. Not being tied to specific features of SQL or JDBC, Carbonado also supports non-SQL database products such as Berkeley DB. In doing so, relational features such as queries and indexes are supported, without the overhead of SQL. Carbonado was originally developed for internal use by Amazon.com, as a revision to an earlier framework. It was released as an Apache licensed open-source project in October 2006. Relational entities are known
