Lowman (1985a; 1985b, 1986) makes a
convincing case for permanency or non-drifting of the Earth's
continents relative to each other and for those continents as
large or larger than Australia. These major continents have been
fixed since at least pre-Cambrian time and are on the North
American Plate, South American Plate, African Plate, Eurasian
Plate, Indian-Australian Plate and the Antarctic Plate. On first
inspection of Lowman's Tectonic and Activity Map (Sept.
1980; 1985b - Fig. 1), it seems similar to maps in other
publications, showing the oceanic rifts and faults separating
various plates on which one or more continents occur. Lowman,
however, has added tectonics, volcanic activities, spreading
rates of the rifts, along with data indicating normal and reverse
faults; other similar maps and charts show only part of the data.
West (1981) discusses the differences between Lowman's Fig. 1 and
the somewhat incomplete maps and charts of others.
