JC11527. Ferro-hornblende. Serpentine dome, New Idria district, San Benito county, California, somewhat near the Benitoite gem mine location. 7 x 10 cm 333g. $25.00. A rarely seen specimen of ferro-hornblende from San Benito County, California. A richly, intergrown group of sharp, lustrous, black, prismatic crystals with minor matrix. There is some controversy as to what to call these odd rocks. Originally they were called barkevikite, since discredited, and called ferropargasite. I could not find a reference for ferropargasite from San Benito on Mindat, but did find a reference calling these ferro-hornblende. Sort of take your pick. I found these two pieces back in the 1970's wandering around the Benitoite gem mine area, looking for outcrops of melanite garnet. |

The white material around the crystals is probably calcite. An older piece, originally purchased from Wards Natural Science, then to the J. P. Osborn and sons collection # 179 then to the Bill Warren collection. I acquired the piece in August 1983 from Bill. Crowley collection #: 734. |
