An overview of the mine . The shoreline of the highly acidic mine lake . A closeup of the shoreline mineralization upon evaporation . Moving upwards the pillows dominate, shown here in the upper pillow lavas near the expedition site. The upper pillows are hydrothermally altered and there are black smoker like deposits of manganese found on top of the pillows, rather like those in the Marin Headlands.
Jaspers are also common in the pillow lavas.
The pillow lava sediment boundary is pretty obvious, just notice how the road and road cuts changes color as it reaches the base of this hill. The white is an overlying limestone that predominates in Cyprus. There is very little chert like we have in Marin over the pillow lavas.
