Thirty-nine samples of granitic rocks from the Quadrilátero Ferrifero, Minas Gerais, Brazil, representing "mixed" ages and at least three distinct Pre-Cambrian ages were analysed for seventeen minor elements. The rocks are placed in five groups:, (1) 2400 million year old group;, (2) Bacao complex younger, a group of mixed rocks...

In the interpretation of magnetic and gravity anomalies, downward continuation of fields and calculation of first and second vertical derivatives of fields have been recognized as effective means for bringing into focus the latent diagnostic features of the data. A comprehensive system has been devised for the calculation of any or all of these...

Hamilton (1959) concluded that in most sediments excess pore-water pressure is equal to zero - that is, the hydrostatic pressure is at atmospheric pressure. This note points out that in terrestrial environments the occurrence of artesian water (excess pore-water pressure) is commonplace and widespread and that such excess pressure is the...

The basin characteristics Σal or L ca are useful in hydrologic studies, but existing methods of determining them are either tedious or somewhat inaccurate. The grid method presented herein lessens the amount of tedious labor and provides an accurate measure of either Σal or L ca . An adaptation of the method could be used to compute the...

In the Owens Valley region of California, volcanic activity of Cenozoic age was confined mainly to three areas near the ends of important faults. The volcanic eruptions seemingly took place in regions of relative tension, if the horizontal movement along these faults was left lateral. The deep depression of Owens Valley may have...

A large fault system, here named the Foothills fault system, is the dominant structural feature of the western Sierra Nevada. The steeply dipping to vertical component faults trend northwestward through an area about 200 miles long and 30 miles wide north of 37°30' north latitude. The faulted Paleozoic and Mesozoic...

The eastern slope of Rocky Mountain National Park, Colorado, has been subjected to at least three separate Pleistocene glaciations, which from oldest to youngest are correlated with the Buffalo, Bull Lake, and Pinedale glaciations of Blackwelder in the Wind River Mountains of Wyoming. In this area, deposits of the oldest glaciation are...

A Precambrian complex of granulite, gneiss, and migmatite, intruded by numerous plutons of granitic rocks correlated with the Silver Plume granite, is exposed in a long narrow belt along the crest and upper slopes of the Tenmile Range, Colorado. The metamorphic rocks are predominantly felsic; bands, lenses, and irregular bodies of mafic rocks rich in biotite,...

Gravity and seismic studies in Mono Basin, Mono County, California, completed during the summer of 1957 revealed a large, roughly triangular block that had subsided about 18,000 ± 5000 feet and received an accumulation of about 300 ± 100 cubic miles of light clastic sediments and volcanic material of Cenozoic age....

Valleys cut in the bedrock in northeastern Ohio by Tertiary and Pleistocene streams have been filled by Pleistocene glacial drift so that there is little surface evidence of their existence. Some of these buried valleys are good sources of ground water, so information regarding the location, depth, and cross-section of the buried...

The Mayagüez area forms the southwestern corner of Puerto Rico, west of 67° W. and south of 18° 15' N. One-third of the 640 square kms is covered by thick alluvium. Unconformities separate a basal complex, two sequences of highly folded igneous and sedimentary rocks, and a younger sequence of gently...

Many areas of schist in the southern Black Hills, South Dakota, have a thin zone of disintegrated rock that is 4-10 feet below the ground surface and parallel to it. Fresh, undeformed schist overlying this zone has moved downhill in a mass-wasting process since the present surface was formed. ...

Cold trypsin dispersion at pH 7.2 was used to obtain cultivable cells and cell groups from tissues of six species of fresh-water bony fishes, a frog, and a turtle. The cells readily attached to glass and were capable of at least limited, and in some cases extended, division in media consisting...

Ordering of boron in a feldspar crystallographic site T1(0) has been found in reedmergnerite, which has silicon-oxygen and sodium-oxygen distances comparable to those in isostructural low albite. If a simple ionic model is assumed, calculated bond strengths yield a considerable charge imbalance in reedmergnerite, an indication of the inadequacy of the...
