A Lithostratigraphic Analysis of the Meteor Crater Ejecta Blanket: Measurements, Assigned Facies, and Unit Thickness

Current models do not sufficiently explain target rock-projectile mixing and ejecta blanket formation for small impact craters (i.e., less than 2km diameter). For example, due to the size of Meteor Crater and the low-velocity at which materials were excavated from the transient crater, the extent of target rock-projectile mixing is expected to be minor. However, based on drilling notes from Dr. Da

Spatial and temporal distribution of sinuous ridges in southeastern Terra Sabaea and the northern region of Hellas Planitia, Mars

Sinuous ridges are an important yet understudied component of Mars' hydrologic history. We have produced a map of sinuous ridges, valleys and channels, and tectonic ridges across southeastern Terra Sabaea and into northern Hellas Planitia (10°-45° S, 35°-80° E) using a CTX mosaic. Although we mapped different types of ridges and negative relief features, the focus of this paper are the sinuous rid

Thermophysical and compositional properties of paleobedforms on Mars

Bedforms on Earth and Mars are often preserved in the rock record in the form of sedimentary rock with distinct cross-bedding. On rare occasions, the full-surface geometry of a bedform can be preserved through burial and lithification. These features, known as paleobedforms, are found in a variety of geographic locations on Mars. Evidence in the morphology of paleobedforms, such as the retention o
