Fluorapophyllite-K
specimen number:
8311116
location:
Phoenix Mine, Keweenaw Co., Michigan, USA
description: The Phoenix Mine in Keweenaw County, Michigan, is an early copper mining locality developed in the 1840s on the Keweenaw Peninsula. The mine worked native copper deposits found in fissure veins and amygdaloidal basalt of the Portage Lake Lava Series. Operations were carried out through underground shafts and drifts that followed the copper bearing zones. Although not as large as some nearby mines, Phoenix was part of the early development of the Michigan copper industry and contributed to the regions mining history.
Fluorapophyllite is not terribly common from Michigan's upper Peninsula. This example shows very good glassy mostly gemmy tabular crystals to 0.7 cm in size across matrix. Minor micro-chipping present, this still in quite good condition. Ex Don and Gloria Olson collection.
Size: 8.0 x 6.0 x 3.0 cm (small-cabinet)
