Description: | A fragment of fine grained, dark Andalusite Hornfel which measures (61mm x 55mm x 8mm). The specimen has fine laminations of mudstone with a schistosity (shiny surface) due to mineral alignment from metamorphism. The white, needle-like minerals of chiastolite are 25mm long and cut across the laminations, with random orientation. The minerals are square in cross-section. AR/CB
