CALCULATED LITHOSPHERIC STRENGTH ENVELOPES: IMPLICATIONS FOR
UNDERSTANDING ELASTIC AND SEISMOGENIC LAYER THICKNESSES ON MARS
Abstract
Calculated lithospheric strength envelopes (s) are rheological models of
the lithosphere that are useful in understanding the elastic () and
seismogenic () thicknesses of the lithosphere. Determinations of Te for
Mars using different techniques use different models of Te as indicated
by rheology in LSEs, and LSEs indicate that the differential stress
fields that cause deformation must be considered in the determination of
both Te and Ts. We do not attempt to review the literature here or to
rank different methods. Our goal is to provide a better understanding of
the different values of Te and Ts published in the literature and to
encourage integration of these data with a physical understanding of the
lithosphere in time and space.
