The gaps in the ages of the compression cycles and isotope analysis of hornblende, biotite, and potassium feldspar suggest that extension was occurring when compression had momentarily ceased.
Os ocos nas idades dos ciclos de compresión e as análises isotópicas de horneblenda, biotita e feldespato potásico suxiren que a extensión estaba ocorrendo cando a compresión cesara momentaneamente.
