Mars rocks covered with uniformly thick dust layer?

    Hello all, I need your help. (I believe this si the correct forum)

    Between 2011 and 2013, i read a news in internet, that the dust that coveres rocks in mars seem to be very uniform, like all rocks that was drilled by mars science laboratory twin rovers, seem to have the same thickness of dust. So there was a news, that some one proposed a project to investigate why it was so uniform.

    however i lost the link to the project, and I cant find it via google. Could anyone help? please?

    This seems very unlikely because of the dust devils on mars. I don't mean it's unlikely that a really small sample set taken by humans might not have had the same or nearly the same thickness, but that it seems very unlikely that the thickness is anywhere near uniform over the whole surface.

    I realize that, and precisely that is what interested them. Moreover I remember it was not a layer of loos dust, it was a layer of *cemnted* dust, i use the term that we use to describe *sticking* of the same in earth, in top of the actual rock. The difference between the cemented laer and the actual rock was determined by the abrupt change in mineral composition as the drills drilled deeper.

    Since it would seem nothing came of those "rocks", here's something you can shift attention to.

    Thank you, I am aware of this :) I am actually looking for the campaign I specifically mentioned, because it used data from the top layer of the drill bore, which is generally rejected, as it is considered contaminated, however, some one found out the contamination was uniform.

    A campaign for what, was this some alien conspiracy theory? There is a website that discuss the rock samples. I see nothing unusual.

    that seems a bit of jumping to it, with all due respects.

    also the mineraloy site is supposed to be a general education site, and wont really contain interesting information.

    You'd be surprised how many conspiracy theories there are out there.
