Seite 32 - The quarry, opened in 1865, measures 300 feet from north to south and 200 feet from east to west and ranges in depth from 10 to 50 feet. It is drained by occasional pumping. The stripping consists of 2 to 3 feet of drift. Rock structure: The sheets, from 3 to 8 feet in thickness, dip 10° W.
Seite 9 - Kaolinite is the most common of the kaolin minerals. The structure of kaolinite consists of a single silica tetrahedral sheet and a single alumina octahedral sheet combined to form the kaolin unit layer (Fig.
Seite 36 - The portion of the Pinacate lava flow which extends across the international boundary is a low mesa about 6 miles from north to south and 5 miles from east to west. The mesa rises from 50 to 100 feet above the Tule Desert, and this elevation seems to measure the thickness of the olivine basalt of which it is composed. The margins are but little dissected and seem to be near or at the original limits of the flow. Small cones and craters dot the surface. One of...

Seite 7 - Columbia River basalt may range in age from Miocene to Pliocene, it is considered to be product of many closely related eruptions and is classed as one formation. Thickness ranges from several feet at flanks of steptoes and embayments along eastern margin of Columbia Plateau to more than 1 mile near center where subsidence is greatest.

Seite 9 - The kaolinite structure is composed of a single silica tetrahedral sheet and a single alumina octahedral sheet joined together so that the oxygen tips of the tetrahedral sheet and one layer of the octahedral sheet form a common layer.
