英文摘要 | We surveyed the subsurface structure in eastern Coprates and Capri Chasmata in the equatorial region using high‐resolution visible images, digital terrain models, and radar sounding data. We identified subsurface reflectors in four areas of the chasmata. At the stratigraphic exposure on the chasmata walls, the corresponding depth of the reflector is ~60 m. The bulk dielectric constants of the layers above the reflectors are calculated as 3.4‐‐4.0, suggesting a rock‐air mixture with ~39.3 and 46.1 % porosity, or a rock‐air‐ice mixture with < 21.2 % water‐ice fraction. This high porosity corresponds to non‐welded and unconsolidated sediments emplaced by aeolian, fluvial and volcanic activities. If water‐ice actually exists, further studies and discussions are required for the mechanism to maintain it within low‐latitudes. |
