An occurrence at the base of the sea cliffs.
Outcropping of blue mica schist, a part of the catalina schist exposed in the cliffs below and hills above Point Fermin. The blue schist can be found as layers and pods inside the sandstone and shale. Micro crystals of various minerals are found in vugs inside solid veins as well as filling in fractures and surface coating on the dense schist blocks.
From Pemberton: "Microscopic crystals of dolomite, partly derived from organic material and with an unusual habit, occur with tar (bitumen) as cement in some Miocene sands of the Point Fermin sea cliffs."
From Pemberton: "The base of the cliff at Point Fermin Park is a sandstone comprised of glaucophane grains. Pebbles of nearly pure glaucophane are found in the sandstone."
