(Figure 1: Photomicrographs. Top left, a disk-shaped gold nugget is encased in sandy matrix material. Dark green chlorite and fine gold particles can be seen in the matrix immediately next to the nugget. Top right, the edge of a rounded nugget emerges from sandy matrix material. Dark green chlorite intergrown with fine gold particles replaces the matrix in places near the nugget. Lower left, dark green to black chlorite and fine gold particles form a distinct clot within sandy matrix. A few coarser gold particles form the core of this clot and may represent the remains of a chemically remobilized nugget. Lower right, a cluster of coarse gold particles forms the core of a dense cluster of very fine gold within sandy matrix material. Coarse gold particles may represent the remains of a chemically remobilized nugget. Note the sharp boundary on the halo of fine gold.)
