Volcanic studies: Part B: Mare Serenitatis cinder cones and terrestrial analogs Volcanic studies: Part B: Mare Serenitatis cinder cones and terrestrial analogs
Small volcanic cones with summit craters or breached walls occur in several areas on the Moon. Most of these features have basal diameters of approximately 1 to 2 km and probably are not more than a few hundred meters in height. None have been so clearly photographed, however, as those shown in Apollo 17 metric and panoramic camera coverage of the southeastern margin of the Serenitatis...

Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows
Orbital photographs taken at low-Sun illumination during both the Apollo 15 (ref. 30-14) and Apollo 17 missions have provided excellent data on the lava flows in the southwestern Mare Imbrium. These photographs have been used recently to present a detailed photogeologic evaluation of these flows and their role in mare volcanism of Eratosthenian age in the basin (ref. 30-15). Eruption of...

Biological data on PCBs in animals other than man Biological data on PCBs in animals other than man
SUMMARY: Polychlorinated biphenyls have become ubiquitous in the world ecosystem in quantities similar to those of DDE. Experimental studies have shown that PCBs have a toxicity to mallards, pheasants, bobwhite quail, coturnix quail, red-winged blackbirds, starlings, cowbirds, and grackles that is of the same order as the toxicity of DDE to these species. Overt signs of poisoning also...
