CAPTION FOR COVER PHOTOGRAPH
3,243 million-year-old spherules in the Fig Tree Group, Barberton Greenstone Belt, South Africa, formed as
a result of large meteorite impacts on the early Earth. The 35-cm-thick spherule bed (S3) is composed of
nearly pure spherules produced during the condensation of an impact-produced rock vapor cloud. The
estimated diameter of the bolide was 20-50 km. The spherules, 0.5-1.5 mm in diameter in the photo, include
silica-(clear), phyllosilicate- (gray), and rutile/anatase-rich (black) varieties; massive and layered types;
and a few originally hollow spherules. This is one of four spherule layers in the Barderton Belt, ranging
from 3,470-3,243 Ma, that represent the oldest known irnpact deposits and provide direct evidence for a
significant flux of large impactors as late as 3.2 Ga. Photograph: D.R. Lowe
