(Cornwall type) The Cornwall type of deposit has supplied nearly all the iron ore mined in Pennsylvania in recent years. The entire production has come from the Cornwall mines after when the French Creek mines at Saint Peter were closed; a few other mines contributed small amounts from time to time.

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." The mine was acquired in by the metallurgist and inventor, Anson Gardner Betts (b.Lansingburgh, NY; d.

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.
Ma, intrusions of molten rock have penetrated at intervals along fissures, gradually to solidify as Dolerite dikes.

These hunters crossed the land bridge.These basaltic rocks were collected by Professor Dumble and Mr. Taff, in Uvalde County, southern Texas.
On the geological map of the United States, compiled by C. H. Hitchcock,there are two of the localities marked near the boundary of the Cretaceous and earlier Tertiary formation, between 99° and ° longitude, and on the 29th degree of latitude.
