Nielsen and Wolter's book, at page 34, discusses
the mineralogy of the KRS and states:
"The elongated grains
exhibit a preferred orientation
that is sub-parallel (nearly parallel) with
the foliation
composed of various mica minerals (muscovite, chlorite and biotite)
that comprise the matrix."


  Aaarrgghh. How are we supposed to parse this sentence?
  I can't tell what is supposed to be composed of mica.
  It's not the foliation, because that is
a physical property of the rock indicating
a significant direction of stress on the rock during metamorphosis.
  It's not the preferred orientation, because that is also
a physical property of the rock, also indicating
a significant direction of stress on the rock during metamorphosis.
  It might be the elongated grains, but then we have to guess at
what words are missing to connect
"The elongated grains" to
"composed of various mica minerals".
  Of course, I assume that there is a connection, rather than
that the writing above should actually have been printed as
two separate sentences.
  As quoted above, the sentence is unclear as to its meaning.
  This would be an example of a style of writing that
is not indicative of scientific thought processes;
it also does not qualify for technical writing standards.

Did you quote the book word-for-word, i.e. verbatim, above?

With one exception, yes.

The exception is that Steve-o changed 'elongate' in the book to 'elongated' in his snippet. Otherwise, it's letter-perfect.
