More will be said ofthis in later chapters. Anderson ( 1986) provided a detailed description of the development of the theory of continental drift and piate tectonics. " It helped to resolve what earlier geologists had observed in Newfoundland and Labrador and in North America, Europe, and North Africa: that the joining of rocks in central New{oundland and the ophiolites of western Newfoundland made little sensewithout this theory. Much of this has now been accepted as a part of tectonic science, in large part as a result of the work of Newfoundland geologist Hank \Tilliams, working at the Memorial Universiry of Newfoundland.
