Fluorescent Chrysotile From Sterling Hill, New Jersey, James A. Van Fleet, Earl R. Verbeek
Fluorescent Chrysotile From Sterling Hill, New Jersey, James A. Van Fleet, Earl R. Verbeek
James A. Van Fleet
Minerals of the serpentine group, notably chrysotile and to a lesser extent lizardite, are widely present at both Franklin and Sterling Hill. They are late-stage hydrous magnesium silicate minerals that formed by hydrothermal alteration of earlier species, among them willemite and tephroite, and are also common components of hydrothermal veins cutting the ore bodies and the enclosing marble (Dunn, 1995). Although long recognized in the area (Fowler, 1825), local serpentine was not documented as a fluorescent mineral until 2004, when a brief description of a fluorescent serpentine from Franklin appeared in The Picking Table (Cianciulli, 2004). In the present paper, …
Hardystonite From The Desert View Mine, California, James A. Van Fleet, Earl R. Verbeek Phd
Hardystonite From The Desert View Mine, California, James A. Van Fleet, Earl R. Verbeek Phd

The fluorescent mineral hardystonite is confirmed in a specimen from the Desert View Mine, California. Hardystonite had been known only from Franklin, New Jersey for over 100 years.

Bedrock Geology Of The East Brookfield 7.5 Min. Quadrangle (Ebq), South-Central Massachusetts: Structural And Petrologic Evidence For The Nature Of Regional Deformation And Kinematics Of The Southern Central Maine Zone, Thomas Bradley Walker
Thomas Bradley Walker
Across-strike shortening from Maine to Connecticut is the most conspicuous orogen-scale feature of the New England Appalachians. Mapping (1:24000) and structural analysis in the EBQ and adjacent quads demonstrate that shortening in the southern Central Maine zone was accommodated by orogen-parallel elongation and orogen-normal flattening and thrusting. Map units are Rangeley Fm. (Sil-Bt-Grt schist and gneiss, Bt-Pl±Grt granofels; thin marble layers); Paxton Fm. (Bt-Pl±Grt granofels; calc-silicate granofels; Bt-Sil-Grt schist); tonalitic Bt orthogneiss (Bt-Pl-Qtz±Grt); migmatitic felsic and mafic gneisses and amphibolite; and leucopegmatites (10-m-scale thickness). Foliations (primarily compositional layering, leucosomes in the plane of flattening, Bt SPO, flattened quartz and feldspar …
