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) and hashCode are also generated. This greatly simplifies the process of defining new entities, since no boilerplate code needs to be written. The process of loading a Storable by key starts by calling a factory method to create an uninitialized instance: Next, the key properties are set and load is called: A "Repository" is a gateway to the underlying database. A few core implementations are available, which include: In addition, composite Repositories exist which support simple replication and logging. All Repositories are created using a builder pattern. Each type of builder supports options specific to the Repository type. When a
