The Servilleta Basalt
Description
The formation consists principally of
Geologists have not reached consensus on whether the alluvium beds should be regarded as part of the formation. These are lithologically similar to nearby sedimentary beds of the Santa Fe Group. Those investigators who include the alluvium in the unit[3] tend to refer to the unit as the Servilleta Formation, while those who do not[1][2] tend to refer to the unit as the Servilleta Basalt.
The formation rests
The lavas appear to have all been erupted from five
Economic geology
The unit can be divided into three sets of flows separated by alluvium in the southern San Luis Valley. The alluvium separating the upper two flows is a significant local aquifer known as the Agua Azul.[4]
History of investigation
The formation was first named by A.P. Butler, Jr., in his unpublished 1946 dissertation.
