Aeroradioactivity Survey and Areal Geology of Parts of East-Central New York and West-Central New England (ARMS-I)

Description: Report concerning "[a]n airborne gamma-radiation survey of Connecticut, Rhode Island, and parts of New York, Massachusetts, New Hampshire, and Vermont" (p. 5) made between 1958 and 1960 that indicated that a broad range of radioactivity exists in those areas depending on the type of bedrock. Correlations are drawn between this radioactivity and the geology of the region.

Condition Survey: Pease Air Force Base, New Hampshire

Description: "The purpose of this report is to present the results of a condition survey performed at Pease Air Force Base (PAFB), New Hampshire, during 14-18 August 1972. The inspection for effects of frost action was performed on 1 June 1972. The three major areas of interest considered in this condition survey were structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost action to the pavement facilities" (p. 1).

Mica-Bearing Pegmatites of New Hampshire: a Preliminary Report

Description: From abstract: Mica has been mined in New Hampshire since 1803. Production from 1908 through 1939 has aggregated 13,326,990 pounds of sheet and punch mica, an annual average of 416,470 pounds. Since 1931 production has been below this average, because of economic conditions rather than depletions. The mica-bearing pegmatites of the Grafton and Keene districts occur mostly in sillimanite-mica schist adjacent to large areas of biotite gneiss. The pegmatite bodies range from a fraction of an inch to more than 200 feet in thickness; most of them are crosscutting, and about 75 percent strike northeast. Mica occurs sporadically in most of them but where present in commercial quantities it is localized in one or more of the following zones: (1) In quartz-plagioclase-muscovite zones 2 to 10 feet from the walls of large pegmatite bodies, (2) in or near quartz masses that occur mostly near the centers of the bodies, (3) in thin dikes 5 to 15 feet thick or in similar offshoots from larger bodies, (4) within large pegmatite bodies, in more or less tabular streaks or zones composed principally of plagioclase, quartz, and muscovite.
