Dumb questions
Hi, sorry if this is stupid, but is there any way that these intrusions could have happened while the strata was still uh, muddy?

(edited out timeframe question)

Re: Holding off on time for the moment
Okay, I retract the time question.

Re: Thanks. We'll hold here
Thanks, Jar, I appreciate it. So we see Peperites that indicate an intrusion into the sediment, and the characteristics of the peperite tells us if the sediment was wet or dry at the time. And the hyaloclastites only form in wet sediments (or other wet material). I think I got that.

Re: Thanks. We'll hold here
Oh, and of course, we can conclude from the above that the sediment being intruded into wasn't still wet?
