Preliminary data on lunar surface material returned by Luna 16 automatic station
Abstract
Results of preliminary investigations of a sample of lunar surface material returned by Luna 16 automatic station are reported. Information on the granulometric characteristics of regolith, its optical properties, types of its constituent rocks, and its mineral composition is given. The chemical composition of major and trace elements for different sections of the core and for the lunar basalt was determined. Isotopic composition of inert gases and of several elements was studied. The Rb/Sr age was determined at 4.85 to 4.25 billion years.
