I have mentioned the breccia found along the South Dalton fault. The massive quartzite is shattered, the fragments being often moved on one another and cemented by limonite. It was first described by Dr. Chester Dewey in 1824, 3 and is mentioned by President Hitchcock in his report of 1841 (p. 588). He enumerates it in his catalogue of the State collection in 1841 (Nos. G04-G0G) and 185G (quartzite, Nos. 59, 60, and 107, 108) as brecciated quartz; cement hematite. It is attributed by Professor Dana to the wedging open of the fragments by the extremely slow action of the depositing limonite. 4 I have found it so closely associated with faults that I have no doubt that it is a fault breccia, produced by friction along the great transverse faults, the fragments being afterwards cemented by infiltrating iron solutions at so low a temperature that the cement is limonite. 1 Am.
