Fig. 11.65. Generalized tectonic map of east Asia, showing
the effects o' f the India-Asia collision. Large open arrows
represent major block movements since the Eocene.
Smaller solid arrows indicate direction of extensional
amalgamation ofNorth America and Europe (Dewey
1982; Friend 1985; McCl�y et al. 1986; Harris and
Fettes 1988; Coward 1990), the Devonian-Carboniferous (Acadian-Alleghanian) orogen of eastern
Canada (Hamblin and Rust 1989; Gibling et al.1992),
