Although researchers call the ejecta ash, it really isn't the type of burned material that most people associate with the word.
The force of the impact of the object against the gas planet caused debris and what scientists call ejecta to shoot away in all directions from the point of impact.
We were basically able to basically locate multiple mortar locations that corresponded with the locations of the craters and the pattern of the ejecta material ejected from the craters.
Other landscape features include crater lakes, fumaroles, lava tubes, sulfur fields and a great variety of lava and other ejecta such as pumice, ash and tuff.
While volcanic ejecta in many parts of the world is acidic, in Java it is chemically basic, rich in soluble plant nutrients, such a calcium, magnesium, nitrogen and phosphorus.
Notice the longitudinal asymmetry quenching asymmetrically, hence protruding the major lobe opposite–also consistent to molten formation processes of Mons Olympus mega-ejecta–a hurricane of high atmospheric rock, ash and dust.
They were able to make some great observations of the ejecta cloud with DIVINER, and we had good signals with our instruments all the way down to impact.
While Nectaris' basaltic flows appear darker than those in most maria, it is one of the older formations on the Moon, and as the terminator progresses you'll be able to see where ejecta belonging to Tycho crosses its surface.
For instance, the model will say some of the ejecta would have been melted and would land as far away as point x.
It would also provide the amount of certain ejecta at certain distances.
