| Caption: | Jenny Pate Limestone. Sandydub old quarry, 1 mile west of Saline. Fife Region. |
| Description: | Dull grey, compact dolomite. Small relics of shells, crinoids and foraminifera are scattered rather sparsely in a matrix of turbid granular dolomite of grain 0.01 mm. The forarninifera are preserved as casts the chambers being filled by pyrites while the walls are recrystallized as dolomite indistinguishable from the matrix. The shell and crinoid fragments, though partly replaced by pyrite, retain the original organic fabric and are probably still calcite. Angular grains of quartz, 0.05 mm across, and carbonaceous particles are scarce. The dolomite is ferriferous and its ordinary refractive index while generally between 1.685 and 1.690, may reach 1.695. Ferriferous dolomite, luteous, micrograined, zoophasmic. SL0117. Britrocks S34590. Magnification x40. Light XPL. |
