nuvel_1_plates.orig: original lon/lat boundaries of plates that was cyber-floating with a NUVEL-1A package we received back in 1999; we don't know the original source nuvel_1_plates: this fixes a couple of minor errors in nuvel_1_plates.orig to make the plate boundary sections continuous _plate: the sections of nuvel_1_plates put together so they form the boundary of the named plate (but the sections are not continuous) .txt: single continuous plate boundary segment with lon/lat points going counterclockwise (courtesy of Jinwei Ren, China Seismological Bureau, Beijing, China)
