Abstract
We provide the first 87Sr/86Sr analysis of the Alcova Limestone. The data strongly support a marine origin for this unit. Furthermore, the data provide an age range, based on their placement on the marine strontium curve, that limits the deposition of the Alcova Limestone to the latest Olenekian to earliest Anisian (Early Triassic-Middle Triassic boundary). This placement is consistent with the timing of the Spathian regression recorded in other transitional marine to non-marine strata of the western USA.
