The current turbulence warp I'm using just kind of swirls the texture around.

warp
{
 turbulence 1/8  //.125
 lambda  3  //3
}

I am wondering, how do make it so that there are also speckles--i.e., almost a
dithered or half-tone pattern?

Depending on the pigment your using you can try turbulence grater than one.
I'd have turbulence of 10 with a gradient pigment map.

Thanks! I'll have to experiment a bit to see what results are possible.

On a further note, has anyone created a (fractal?) pattern that can produce the
rippled effect found in this satellite view of the Himalayas?

Thanks again!

My best guess should be f_ridged_mf() function available in the 
functions.inc standard include file though erosion is hard to simulate.
For speckles in transitions, did you play with lambda and omega?

BTW I'm following your excellent work and I jump on the opportunity to say 
it is a very good job :-)

Thanks. I will try that too.

Thank you! Once I get the orbit code working and add a nice atmosphere I will
release it.
