Map of the tuff aquitard (lower tuff units) in Yucca Flat, Nevada Test Site
Technical Report
·
OSTI ID:6288173
The tuff units of Yucca Flat, Tertiary in age, have been divided into an upper aquifer and a lower aquitard. The tuff aquitard comprises all the tuffs and associated sedimentary rocks older than the Paintbrush Tuff. The aquitard formations consist of nonwelded to densely welded ash-flow tuff, ash-fall tuff, and reworked ash-fall and tuffaceous sandstone, siltstone, and claystone. One common feature among these formations is matrices consisting of zeolite or clay minerals. The tuff aquitard overlies two carbonate aquifers and two clastic aquitards of Precambrian and Paleozoic ages.
