An incorporated city located on the Delaware River. It is the home of Lafayette College and its famous Professor of Mineralogy, Dr. Arthur Montgomery, who studied this area and published extensively on its mineralogy.

For the sake of eliminating confusion, the localities on Chestnut Hill, located at Chestnut Hill (unincorporated populated place) in Forks Township, are included with Easton since this ridge is adjacent to the Easton city limit on the N.

Axinite-(Mn) ?
Formula: Ca2Mn2+Al2BSi4O15(OH)
Description: Data from an unspecified source in Gaines et al. (1997) were seen in an unquoted table of chemical analyses. original source unknown. Indications are that the chemical analysis could have been from another Pennsylvanian locality, but erroneously attributed to Easton. As noted above the basis for the listing Easton as a locality for Axinite-Mn is flimsy at best. In the American Mineralogist, 1937, Peacock provides crystallographic data for axinite said to be “from near Easton, Pennsylvania, probably the same locality as "near Bethlehem, Pennsylvania," which yielded the axinite described by Frazier (1882)”. Aside from this one note of possible confusion, near the top of pg. 597, the specimen is repeatedly said to be “from near Easton”. Therefore, it seems that sometime prior to 1937 a specimen of axinite, labeled as such, was sent to Harvard. The Harvard Mineralogical Museum's online catalog lists specimen 80841, in the "Research Collection" as being from "Easton". There is a very high probability that the citation is in error and is an artifact of poor labeling. No locality assigned to “Easton” appears in either Montgomery (1969) or Smith (1978). There are 8, probably 9, documented occurrences of axinite-group minerals in alpine cleft type fracture fillings scattered along the northwest margin of the Reading Prong/Hudson Highlands between Fishkill, NY and Bethlehem, Pa. Portions of the Easton area meet the criteria that appear to govern such occurrences. Although the occurrence of axinite-group minerals in the Easton area is entirely possible no reliably documented find is yet known.

Description: Described first as "Chloritic Vermiculite" by Clarke and Schneider in 1891. Likely the same material as described by professor Frederick Burritt Peck in 1905 as an "alteration of phlogopite to serpentine", noting specimens from both Chestnut Hill and from the continuation of the serpentine belt at Warne's quarry (Royal Green Quarry), across the Delaware river in Phillipsburg, New Jersey. Analysis by Merril and by Eyerman in 1911.

Geochronology

Mineralization age: Proterozoic : 1292.4 ± 12.6 Ma to 985 ± 7 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
