"the annual report of the geological survey of arkansas of
1890," chapter 3, "whetstones and novaculites of arkansas".
forthwith:
ohio: sandstones are found at berea in cuyahoga county, amherst in
lorain county, hocking river in hocking county, manchester in summit
county, and farmington and mesopotamia in trumbull county.
new hampshire: a fine-grained stone from lisbon in grafton county
was known as the "chocolate." those from orford came from the shore
of indian pond and were sold under the "indian pond" brand name.
other grafton county stones are found at littleton, haverill, and
piermont. a silurian novaculite is found at tamworth in carroll county.
new york: there is silurian and cambrian novaculite slate in
columbia county at clermont, germantown, greenport, livingstone,
rogers island, stockport, and stuyvesant. there is sandstone at
labrador lake in cortland county and beaver kill river and monticello
in delaware county. silurian whetslates are found in rensselaer county.
vermont: there are oilstone quarries on an island in lake
memphremagog. the island is about seven miles west of stansted
village. one quarry is now entirely underwater and the other partly
so. these were large quarries with stones of good repute. there is
cambrian novaculite slate at thetford in orange county and at
guilford and marlborough in windham county. huronian mica schist is
in windsor county at ludlow, plymouth, and stockbridge. cambrian
mica schist is found in newport, trasburg, and brownington. there is
huronian talcose schist at northfield in washington county and mica
schist at berkshire and fairfield in franklin county.
at least it says where "chocolate" is from. without knowing if the
deerlick stones were of a fine-grained sandstone (silurian sandstone
can be remarkably fine-grained) or of novaculite, it'd be harder to
narrow it down further than this, i guess.
paul's slate could be novaculite slate, either cambrian or silurian.
true arkansas novaculites are lower siluran, and are fairly thickly-
bedded (hence their abundance).
i am a hard-arkansas/lily-white washita/medium india man, myself.
cool thread.
