The chemical composition of the lunar surface material at a maria landing site has been determined by the alpha-scattering technique. Oxygen, silicon, and aluminum have been identified in the preliminary evaluation of the data. The general chemical composition is similar to that of a silicate of a basaltic type. 

Chemical Analysis of the Moon at the Surveyor VII Landing Site: Preliminary Results

The alpha-scattering experiment aboard Surveyor VII has provided a chemical analysis of the moon in the area of the crater Tycho. The preliminary results indicate a chemical composition similar to

Chemical composition of the lunar surface at the Surveyor landing sites

Alpha-scatter analyses of surface material at two widely separated points on the lunar mare are interpreted as being compositionally similar to terrestrial tholeiitic flood basalts. Material analyzed

Chemical Composition of the Lunar Surface in Mare Tranquillitatis

The composition is, in general, basaltic; the low sodium and high titanium contents, however, are distinctly different from the abundances in meteorites or common terrestrial rocks.

Chemical Composition of the Lunar Surface in a Terra Region near the Crater Tycho

The analytical results provide direct evidence for chemical differentiation in the moon and indicate a lunar crust of appreciably lower density than the whole moon and with lower density and higher albedo than lunar mare material.

Alpha Radioactivity of the Lunar Surface at the Landing Sites of Surveyors 5,6, and 7

The lack of such a deposit at two other lunar sites suggests lower local concentrations of uranium there and the presence of polonium-210 in amounts that are close to equilibrium indicates a continuous turnover rate of lunar material at this site of less than 0.1 micrometer per year.

Surface Structure and Chemical Composition

After a brief survey of the morphology of the principal types of formations encountered on the lunar surface, and reconnoitred more recently in situ by the astronauts of successive Apollo missions,

Surveyor V: Discussion of Chemical Analysis

Material of basaltic composition at the Surveyor V landing site implies that differentiation has occurred in the moon, probably due to internal sources of heat. The results are consistent with the

Post-mission data analysis of Surveyor mission chemical data

The prime, data from the chemical analysis experiments on Surveyor 5* 6, and 7 have been critically examined and . analyzed.. Together with associated, laboratory work, these have led to final

Chemical Composition of the Lunar Surface in Sinus Medii

The titanium content at Sinus Medii is lower than that at Mare Tranquillitatis; this suggests important differences in detailed chemical composition at different mare areas on the moon.

Chemical analysis of the lunar surface in the Surveyor program.

Chemical analyses of lunar surface materials were obtained in situ by Surveyors 5, 6, and 7. Mare samples were analyzed by Surveyors 5 and 6, which landed in Mare Tranquillitatis and Sinus Medii,



Chemical analysis experiment for the Surveyor lunar mission.

An experiment has been designed to determine the chemical composition of the lunar surface on the Surveyor soft-landing science missions to the moon. The instrument utilizes the characteristic

Instrument for Lunar Surface Chemical Analysis

An instrument has been designed and constructed which utilizes the interactions of monoenergetic alpha particles with matter for surface chemical analysis. The source of alpha particles is a

Chemical analysis of surfaces using alpha particles

The chemical analysis of surfaces using α-particle interactions has been investigated. Simple instruments incorporating Cm242 α sources and semiconductor silicon detectors are described. The

Chemical Analysis of Surfaces by Use of Large-Angle Scattering of Heavy Charged Particles

A simple apparatus for analyzing surfaces based on Rutherford scattering and nuclear scattering ideas can be made by using an alpha source such as Cm244, a solid state detector, and an electronic pulse height analyzer.
