In the mine, flow is strongly channeled to the mineralized veins as a consequence of their high fracture density and permeability. The transmissivity of the barite and fluorite veins was measured between T = 2.26 × 10 −5 m 2 s −1 and 5.21 × 10 −4 m 2 s −1, which is much higher than the mean T-value of gneiss of the Black Forest basement …Web

The earliest mining in the district was for lead at the Columbia Mine, Crittenden County, in 1835 (Ulrich and Smith, 1905, p. 115). From 1835 to the early 1870s, little fluorspar was mined. Only small amounts were produced from the early 1870s to about 1890, when an expanded market was created by the …
