Most of the pegmatites lie in the Middletown district, occurring principally in the Bolton schist and Monson gneiss. The pegmatites range from distinctly zoned bodies to those that are essentially uniform mixtures of the component minerals. Beryl in the zoned pegmatites commonly is present in greater concentration in one or more zones than in others. It occurs in the majority of pegmatites examined, but on the basis of crystal counts only 10 pegmatites, either in whole or in sizable part, average 0.2% or more beryl. Six structural types of beryl deposits are described and illustrated: border-zone, wall-zone, intermediate-zone, pod, fracture-controlled, and disseminated. Some pegmatites contain two or more types.Grades and tonnages of 14 beryl-bearing pegmatites are tabulated. Total indicated and inferred beryl-bearing pegmatite is 207,885 tons containing 859 + tons of beryl. Most of the beryl is in crystals too small to be economically separable by hand sorting, and barring a marked increase in the price of beryl, milling operations would have to be supported primarily by the yield of salable feldspar, scrap mica, and possibly quartz.

The zinc content ranged from 39 p.p.m. in the fruit of the false solomon's seal (Smilacina racemosa) to 5,400 in the horsetail (Equiseteum arvense}. This latter plant varied considerably in zinc at different places on the slime ponds. The zinc contents of the aspen (Populus grandidentata}, ragweed {Ambrosia artemisiifolia), and horsetail grown on normal soils are compared to those on the slime ponds and it is recommended that the poplar and ragweed be studied further as indicators of zinc ore bodies.

It includes parts of Arkansas, Mississippi, Tennessee, Kentucky, and Missouri. In 1940 about 2,700,000 people inhabited the region.Ground water is one of the most valuable natural resources of the region. It is estimated that 95 per cent of all the water used in the Upper Embayment comes from the ground.Structurally the Embayment is a downwarped, downfaulted trough in Paleozoic rocks, in which have been deposited sediments ranging in age from Cretaceous to Recent. Very productive water-bearing formations extend throughout most of the region but the total quantity of water perennially available is unknown, and little information is available on the quality of the water.The formations comprise a natural hydraulic system underlying parts of several States, and a study of the geology and hydrology of the entire region is needed. Such a study is necessary because additional ground-water supplies will be required with the future development of the region. In order to develop the region wisely the quantity and quality of the water perennially available must be known.

The hard-rock core is flanked on the north and south by limestones and clastic rocks of late Oligocene and early Miocene age, which have been gently arched and uplifted. Similar rocks were deposited in late Miocene or early Pliocene time along the west coast. During the Quaternary the island has been separated from the other major Antillean islands by faulting and has been arched, uplifted, and tilted to the northeast. Alluvium and littoral deposits have partially filled the valleys and have formed coastal plains on the north and south. The Upper Cretaceous volcanic and associated rocks yield small supplies of water to wells in most places. The Tertiary limestones yield large supplies in some places on the north, south, and west coasts. The Quaternary sands and gravels are the most important aquifers. They yield about 200 million gallons a day to wells in the main south coastal plain alone. The water is used largely for irrigation. A total of perhaps 250 to 300 million gallons a day is pumped from wells in the island, and moderate to large additional supplies are available in some places.

biogeo-chemical prospecting","docAbstract":"The zinc content of thirty different kinds of plants growing on slime ponds containing on the average 12.5 per cent zinc were determined by the dithizone method. The zinc content ranged from 39 p.p.m. in the fruit of the false Solomon's seal (Smilacina racemosa) to 5,400 in the horsetail (Equiseteum arvense). This latter plant varied considerably in zinc at different places on the slime ponds. The zinc contents of the aspen (Populus grandidentata), ragweed {Ambrosia artemisiifolia), and horsetail grown on normal soils are compared to those on the slime ponds and it is recommended that the poplar and ragweed be studied further as indicators of zinc ore bodies.

The activity of the gabbro averages about 0.3 alphas/mg./hr., that of the tonalites, 0.8, the granodiorite 1.3, and the granites over 2.0. The activity of the average rock of the batholith is about 0.9 alphas/mg./hr. Most of the rocks have been analyzed, and modal compositions are given. The radioactivity and the percentages of K2O, SiO2 and PbO are plotted on a variation diagram. The variation curve for activity nearly parallels that for K2O, and the ratio of activity to K2O is about 0.5. The radioactivities of some rocks fall far from the variation curve, and degree of activity correlates with K2O content. A less-marked correlation between activity SiO2 and PbO was also noted. The K2O, SiO2, PbO, and radioactivity concentrate in the residual liquid during crystallization and differentiation. PbO follows K2O closely, as it is concentrated in the K2O minerals, but radioactivity is very low in the K2O minerals and is greatly concentrated in the accessory minerals.

Two planar structures, one a compositional layering due to variations in the relative proportions of olivine, pyroxene, plagioclase feldspar, and chromite, and the other a foliation caused by the orientation of pyroxene crystals in peridotite, are in general parallel, but diverge in a few places. Dips are fairly constant, being moderate to the northwest over most of the area, but sharp reversals occur immediately adjacent to irregularities in the chromite deposits. Two prominent joint sets are present: (1) Cross joints striking parallel to the strike of the foliation and dipping approximately at right angles to it; and (2) longitudinal joints striking parallel to the direction of dip of the foliation and nearly vertical. Gabbro dikes follow the first set, chrysotlle veins the second. Within the ore bodies dikes are commonly coarser‐grained, larger, and far more abundant than in peridotite; they enclose coarse, angular fragments of chromite. ©1947. American Geophysical Union.

This report was prepared at the request of the Atomic Energy Commission.
\nPresent investigations are summarized to show the scope of the present Trace Elements program, grouping individual projects into related types of investigations.
\nPlans for future investigations on an expanded scale are outlined. These should provide sufficient data and knowledge of the occurrence and availability of uranium, thorium, and related elements, to permit a more complete evaluation of domestic resources. Reconnaissance projects are designed to discover possible new sources of uranium and thorium and to select areas and materials warranting further investigation. Typical projects leading to the estimation of reserves are the investigation of the carnotite ores of the Colorado Plateau by geologic mapping, exploratory drilling, and related research, and investigation of asphaltic sandstone in Emery County, Utah. Extensive research will be undertaken to establish the principles governing the geological and geochemical relations of uranium, thorium, and associated elements as an essential guide in appraising domestic resources. Particular emphasis will be placed on phosphatic rocks and black shales which offer ultimate resources of uranium far greater than carnotite ores. All the foregoing investigations will be accompanied by chemical, gephysical, and mineralogical research and analytical work.
\nUnder plan of operation is discussed the organization of the Trace Elements Unit, space requirements for laboratory and office, the scheduling of investigations, and other related problems. The proposed scheduling of work calls for approximately 109, 173, and 203 man years in fiscal years 1948, 1949, and 1950 respectively. Definite plans have been formulated only for the next three fiscal years, by which time it is assumed the program will reach stable proportions or can be altered as experience dictates.
\nUnder cost of operation is set forth the funds available in fiscal year 1947, the status of funds transferred from Atomic Services (14-217/80920), and funds necessary in succeeding fiscal years. The estimate for fiscal year 1948 inclues a non-recurring item of $1,025,000 for establishing adequate laboratories for chemical, physical, spectrographic and mineralogic research and analytical work. The total funds required in fiscal years 1948, 1949, and 1950 to support the proposed program will be $2,440,000, $2,161,000 and $2,198,000 respectively. The Geological survey anticipates contributing from its appropriation in fiscal years 1948, 1949 and 1950 approximately $243,000, $350,000, and $400,000 respectively; the balance of the necessary funds to be contributed by the Atomic Energy Commission in fiscal years 1948, 1949, and 1950 will be approximately $2,196,900, $1,811,000, and $1,798,000 respectively.

Individual issues contain information on volcanic activity, volcano research, and volcano monitoring in Hawaii. Information on volcanic activity at other locations is also occasionally included.
The Volcano Letter was published by HVO through multiple changes in administration, including the Hawaiian Volcano Research Association (1925 to 1932), the U.S. Geological Survey (1932 to 1935), the Department of the Interior (1935 to 1938), and the University of Hawai‘i (1938 to 1955). Issues 1-262 were published weekly from January 1, 1925, to January 2, 1930, and consisted of a single page of text. Issues 263-384, also published weekly, from January 9, 1930, to May 5, 1932, were generally longer—four pages— and provided more detail on volcanic activity, including photographs, maps, and plots. Weekly issues 385-387, published May 12-26, 1932, were a single page of text due to budget reductions brought on by the Great Depression. Budget restrictions reduced the publishing frequency to monthly for issues 388-428, covering the period of June 1932 to October 1935; these issues were generally shorter, 1-2 pages, and sometimes featured figures. From November 1935 to July 1938, issues 429-461 remained monthly but increased in length (generally eight pages) and featured figures frequently. Issues 462-530, published over the period of August 1938 to December 1955, varied in length from 2-15 pages, but were published quarterly, rather than monthly.
Six of the Volcano Letters are misnumbered:
Jan. 21, 1926 number is 55 though it should 56
July 29, 1926 number is 82 though it should be 83
Feb. 16, 1928 number is 161 though it should be 164

Niihau lies 171/2 miles southwest of Kauai. Its area is 72 square miles, and its highest point has an altitude of 1,281 feet. The population is about 180, chiefly Hawaiians. The annual rainfall at Kiekie, the ranch headquarters, generally ranges between 18 and 26 inches. The chief industries are the raising of sheep and cattle and production of honey. The island is privately owned.
The main mass of the island is composed of a deeply weathered remnant of a basalt dome of Tertiary age, cut by a dike complex trending NE-SW. These Tertiary rocks are herein named the Paniau volcanic series. The central vent lay about 2 miles out to sea to the east of the present island. The dome, after deep gulches were cut into it by stream erosion and it was cliffed all around by the sea, was partly submerged. During Pleistocene time a broad wave-cut platform on the north, west, and south sides was built above sea level and widened by the eruption of lavas and tuffs, from 9 vents now visible and other vents now buried, to form a low coastal plain. These Pleistocene volcanic rocks are named the Kiekie volcanic series. Ash from Lehua Island, a Pleistocene tuff cone, has been drifted into duties on the north end of Niihau. Lithified dunes that extend below sea level, and the small outcrops of emerged fossiliferous limestone above sea level, indicate the plus 100-foot, minus 60-foot, plus 25-foot, and plus 5-foot eustatic stands of the sea correlative with changes in the volume of the polar ice caps and concurrent changes in the configuration of ocean basins.
Calcareous dune and beach deposits, short stretches of nullipore reef and beach rock, and playa and alluvial deposits constitute the Recent rocks.
No perennial streams exist on the island but about a dozen playa lakes, fresh or brackish during rainy weather, lie on the plain. The domestic water supply is rain caught from roofs. Only three wells on the island yield water with less than 25 grains of salt per gallon (260 parts per million of chloride). Typically, water holes for stock are about 15 feet across, 5 feet deep, and 8 feet wide. They have been dug in the lowlands where the depth to water is usually less than 5 feet. Forty-six dug wells and water holes exist, the water of some of which has become too salty for stock. Two or three deep wells were drilled 500 to 1,000 feet below sea level, but they encountered salty water. Three wells, not yet used, have been excavated in the Tertiary basalts. One of them has an infiltration tunnel at the bottom. Two seeps perched on vitric tuff beds more than 500 feet above sea level carry large quantities of salt leached from spray that falls on their recharge areas. Several sites are recommended for developing additional water for stock. The island, however, will always be short of domestic water because of aridity, unfavorable geologic structures, continuous deposition of salt spray, and abundant authigenic salts in the lake beds.
Among the lavas of the Paniau volcanic series, of Tertiary age, olivine basalts probably predominate but ordinary basalts are abundant. Picrite-basalt of the primitive type, containing abundant olivine phenocrysts, also occurs. Andesites are probably present but are rare. Most of the lavas of the Kiekie volcanic series, of Pleistocene age, are olivine basalt, but one is transitional between olivine basalt and picrite-basalt. In many of the Pleistocene lavas the late-crystallized augite is titanian. A single occurrence of melilite-nepheline basalt has been reported. Chemical analyses of five rocks are listed.
The island of Molokai is the fifth largest of the Hawaiian Islands, with an area of 250 square miles. It lies 25 miles southeast of Oahu, and 8.5 miles northwest of Maui. It consists of two principal parts, each a major volcanic mountain. East Molokai rises to 4,970 feet altitude. It is built largely of basaltic lavas, with a thin cap of andesites and a little trachyte. The volcanic rocks of East Molokai are named the East Molokai volcanic series, the basaltic part being separated as the lower member of the series, and the andesites and trachytes as the upper member. Large cinder cones and bulbous domes are associated with the lavas of the upper member. Thin beds of ash are present locally in both members. The lavas of the lower member are cut by innumerable dikes lying in two major rift zones trending eastward and northwestward. A large caldera, more than 4 miles long, and a smaller pit 0.8 mile across existed near the summit of the volcano. The rocks formed in and under the caldera are separated on plate 1 as the caldera complex. Stream erosion has cut large amphitheater-headed valleys into the northern coast of East Molokai, exposing the dikes and the caldera complex.
West Molokai is lower than East Molokai, rising to 1,380 feet altitude. It was built by basaltic lavas erupted along rift zones trending southwestward and northwestward. Many of the flows were unusually fluid. The volcanic rocks of West Molokai Volcano are named the West Molokai volcanic series. Along its eastern side, the mountain is broken by a series of faults along which its eastern edge has been dropped downward. West Molokai Volcano became extinct earlier than East Molokai Volcano, and its flank is partly buried beneath lavas of East Molokai.
Both volcanic mountains were built upward from the sea floor probably during Tertiary time. Following the close of volcanic activity stream erosion cut large canyons on East Molokai, but accomplished much less on drier West Molokai. Marine erosion attacked both parts of the island, producing high sea-cliffs on the windward coast. In late Tertiary or early Pleistocene time the island was submerged to a level at least 560 feet above the present shore line, then reemerged. Later shifts of sea level, probably partly resulting from Pleistocene glaciation and deglaciation, ranged from 300 feet below to 100 feet or more above present sea level. Marine deposits on the southern slope extend to an altitude of at least 200 feet. Eruption of the Kalaupapa basalt built a small lava cone at the foot of the northern cliff, forming Kalaupapa peninsula; and a small submarine eruption off the eastern end of Molokai built the Mokuhooniki tuff cone, the fragments of which now form Hooniki and Kanaha Islands. Deposition of marine and fluviatile sediments has built a series of narrow flats close to sea-level along the southern coast.
Nearly the entire island is underlain, close to sea level, by ground water of the basal zone of saturation. Beneath West Molokai, the Hoolehua Plain between West and East Molokai, and the southern coastal area of East Molokai, the basal water is brackish. Beneath much of East Molokai, fresh basal water is obtainable. Small amounts of fresh water are perched at high levels in East Molokai by thin poorly permeable ash beds. Fresh water is confined at high levels in permeable compartments between poorly permeable dikes in the rift zones of East Molokai, and can be developed by tunnels. Projects to bring the abundant surface and ground water of the large wind ward valleys to the Hoolehua Plain are described. Future developments are suggested. All wells and water-development tunnels are described in tables.
