Crater Outflow (Venus)
Reference work entry
A crater outflow is a relatively thin (sometimes radar transparent) and often lobate lava-like flow feature associated with an impact crater on Venus. A crater outflow is typically asymmetrically distributed around a crater.
Crater outflows are clearly distinguished from ballistic ejecta. Many of them have an often lobate, radar-bright, lava-like deposit originating within the continuous ejecta blanket and flow for up to several crater diameters along topographic gradients but in some cases, initially uphill (downrange from the crater). They often have fluvial-like morphologies and sinuous channels originating on, cutting through, and continuing away from fluidized ejecta blankets (Johnson and Gaddis 1996; Komatsu et al. 1991).
