Field observations indicated that the crusts had not formed recently, but are related to Tertiary clastic sediments common in the area.
Yet the absence of limnic lamellae, the limited horizontal distribution, and the frequent intercalation within relatively coarse-grained clastic sediments render the concept of formation from lake-deposited carbonate muds unlikely.
Rift-related clastic sediments thicken toward the east, and associated rift-related magmatism took place intermittently between 615 and 550 Ma.

Gold mineralization at Vila Nova is associated with carbonate altered, sheared and folded banded iron formation ("BIF") within a sequence of clastic sediments, mafic volcanic and ultramafic rock.
