The NGB is bounded by a felsic intrusive rock known as a tonalite (see map below). Both the NGB and the tonalite are cut across by a similar type of felsic rock called a pegmatite.The Principle of Cross-Cutting Relationships: When a rock unit such as an igneous intrusion or a geologic feature such as a fault cuts across another, the one that cuts across is younger. Intrusion "G" is the youngest rock unit on the above diagram. Inclusions: When one rock unit contains a piece of another, the rock unit that includes
