The sequence consists of alternating stacks of massive, clast-supported carbonate conglomerate (lacking Blue Ridge volcanic or cover rocks) and thin, well-bedded, finer-grained carbonate.

A geologist working in a national park finds a mineral. He is carrying a lit that contains a penny, a hand lens, a piece of tile, a geologic hammer, and a jackknife. Describe how the geologist can use these items to determine some of the mineral's characteristics. The deposit was said by Emerson () to have been worked extensively in before being abandoned due to the "California gold excitement."

origin of this mafic unit is uncertain, but textural evidence supports an intrusive origin. An old shaft was sunk on a foot wide quartz vein which is sandwiched between two foliated mafic layers. These mafic layers contain more pyrite than the quartz vein.

A trench uncovers another quartz vein which is located at the contact. - The geological formations present in the Pietermaritzburg area consist of an ancient ( Ma old), solid, but greatly contorted Basement, and a succession of more recent and much less deformed sedi-mentary cover rocks overlying the Basement.
