This paper presents petrologic and compositional studies of matrices and clasts from seven Apollo 15 polymict breccias, which demonstrate the diversity of rock types at the site in comparison with rocks found at other sites. The mc from at least two dia7erent lava flows. CATALOG OF APOLLO 15 ROCKS Part 1. Mare Volcanism. Under . The Apollo 15 landing site was in the Apennine Highlands, and close to Hadley Rille - a long, narrow winding valley. The Genesis Rock is a sample of Moon rock retrieved by Apollo 15 astronauts James Irwin and David Scott in 1971 during the second lunar EVA, at Spur crater.It is currently stored at the Lunar Sample Laboratory Facility in Houston, Texas.It is sample number 15415. The Moon is not a primordial object; it is an evolved terrestrial planet with internal zoning similar to that of Earth.

Approximately 76 kg of lunar material including soil, rock, core-tube and deep-core samples were returned to Earth. National Aeronautics and Space Administration . This glass is very rich in the element magnesium, which causes the green color. Approximately 76 kg of lunar material including soil, rock, core-tube and deep-core samples were returned to Earth. These samples addressed both of the pre-mission objectives. Lindstrom, M. M.; Marvin, U.

Houston, Texas Rocks from the floor of the Taurus-Littrow Valley are mostly mare basalts. 1. The dark basalt rock, collected near Hadley Rille on the edge of the Imbrium Basin (Mare Imbrium), is about 13 cm (5.1 inches) long and is representative of the mare lavas that filled the basin 3.3 billion years ago, several hundred million years after the impact that created Imbrium. The Apollo 15 landing site was in the Apennine Highlands, and close to Hadley Rille - a long, narrow winding valley. The dark, flat often circular regions called lunar maria (singular form: mare) are composed of the rock basalt. Before Apollo, the state of the Moon was a subject of almost unlimited speculation. Top Ten Scientific Discoveries Made During Apollo Exploration of the Moon. The Apollo 15 Lunar Sample A Preliminary Descripti Apollo 15 Preliminary Examination T Samples returned from the A pollo 15 site consist of mn breccias with a variety of premare igneous rocks. Although described in PET (1972) as closely resembling 15445 and 15455 from Spur Crater, 15405 is actually quite different in melt composition, texture, and clast population.

The fine-grained crystallinity and large holes indicate that this rock crystallized near the top of a molten lava flow. Chemical compositions of some soils and rock types from the Apollo 15, 16, and 17 lunar sites ... Abstract. Title: Exploring the Moon pdf Author: NASA 15015-15299 GRAHAM RYDER LUNAR AND PLANETARY INSTITUTE NORTHROP SERVICES, INC. OCTOBER 1985 . Rock sample columns comprise the type of sample, its mass, a brief descriptive name, and the container(s) in which it was brought to earth. basalt sample from the Moon Basalt sample returned from the Moon by Apollo 15 astronauts in 1971. This basalt sample was collected near the rim of Hadley Rille. Pyroclastic glass was also collected on Apollo 17. Apollo 15 kicked off the most ambitious lunar landings, with the remaining crews spending several days on the moon's surface and hauling home rocks of many different kinds. Apennine front revisited: diversity of Apollo 15 highland rock types. B.; Vetter, S. K.; Shervais, J. W. Abstract . The Apollo 17 crew collected 741 individual rock and soil samples, including a deep drill core that included material from 3 meters below the lunar surface, with a total mass of 111 kilograms. LYNDON B. JOHNSON SPACE CENTER . Although described as fractured in the Apollo 15 Lunar Sample Information Catalog (1974), it really resembles a block of a lava or welded slablets (Imbrium Consortium 1976; Marvin subsection p. 76). NASA/ADS.

Several types of volcanic glass occur in the Apollo 15 samples, the most common and famous of which is the green glass. Studies of the green glass indicate that it originated at about 400 kilometers below the Moon's surface. The bulk chemical co textures of these rocks confirm the previous conclusion IthAt t, The following pages are an inventory of all numbered Apollo 15 rock samples, updated from the Apollo 15 Sample Information Catalog (1971); regolith and core samples are not included. Title: Chemistry of Some Rock Types and Soils From the Apollo 15, 16, and 17 Lunar Sites: Authors: Nava, D. F. Publication: Abstracts of the Lunar and Planetary … Apollo 15 Basalt.
