We analyze the performance of two 2D gravimetric interpretations for delineating the basement
relief surface of a sedimentary basins. The first method employs as interpretation model a set
of prisms and the second one a discrete mobile operator compounded by ribbons. The operator
is composed by horizontal 2D ribbons distributed along the horizontal and vertical directions.
In the gravity interpretations, we use a 2D gravimetric inversion method that delineates
discontinuous surfaces of the tops of the basement of the sedimentary basin displaying constant
density contrast relative to surrounding crystalline rocks. This inversion method produces
stabilized estimates of the depths of the top of the basement through the Total Variation (VT)
functional. We apply both methods to synthetic and real data collected in Steptoe Valley,
Nevada, United States. |
