  • Why Does Basalt Weather Faster Than Granite? | Hunker

    Basalt is primarily made of the mineral oblivine, which has no cleavage or planes of weakness. The second most abundant mineral is pyroxene, which has 90-degree cleavage and breaks easily. Plagioclase, which is typically light to dark gray in color, also has 90-degree cleavage and a .

  • Basalt ~ Learning Geology

    Basalt is a fine grained volcanic igneous rock formed of plagioclase and pyroxene minerals. It is most commonly formed by lava flow and in sills and dykes. Basalt is similar to gabbro in composition but the difference lies in the grain size of the two rocks.

    The waves expose, polish and even sort the minerals and pebbles of various minerals. Using a canoe or small boat, watershoes and plenty of time, walk the shore and watch for veins and amygdaloids. Observe the interiors of basalt flows where vesicle cylinders, pegmatites, joints and veins may expose these distinctive minerals (see diagram).
