The abstract states:

"...variations in the topography of the Precambrian basement and
faulting from the Bolivar-Mansfield Tectonic Zone are responsible
for the geophysical anomalies..."

and

"Therefore, there is currently no evidence in support of the
claim that the Echo Cliff structure is an impact structure."
