Well: KCLA-21

FRAME 3-7. Kern River sandstone from Canal field (KCLA21, 3450'). Note high primary porosity (light blue epoxy), yellow-stained potassium feldspar, and abundant biotite and hornblende (yellow-brown and green). Field of view 2.lmm. Plane light.

FRAME 3-8. Etchegoin sandstone from Canal field (KCLA21, 5773'). Note skeletal hornblende in center of photo, with partial clay rim preserved. Note primary and secondary porosity (light blue epoxy). Field of view 1.05mm. Plane light.

FRAME 3-9. Stevens sandstone from Canal field (KCLA-21, 8326'). Note carbonate (dolomite?) rhombs growing within biotite cleavage flakes in left center, upper left, and right center of photo. Note polycrystalline quartz along left margin. Field of view 2.lmm. Crossed Nicols.

FRAME 3-10. Stevens sandstone from Canal field (KCLA21, 8436'). Note extensive highly birefringent calcite cement, biotite and hornblende (top center and upper left), twinned plagioclase (center and left), and volcanic rock fragments (center and lower right). Field of view 2.lmm. Crossed Nicols.

FRAME 3-11. Stevens sandstone from Canal field (KCLA-21, 8436'). Note extensive highly birefringent calcite cement and coarse twinned plagiociase grains (center and lower right). Field of view 2.lmm. Crossed. Nicols.
