... coincide with the main volcanic pulses of the Sierra Madre Occidental. The distribution of epithermal deposits can be thus divided into three main groups: (1) between ~48 and ~40 Ma, (2) between ~36 and ~27 Ma, and (3) between ~23 and ~18 Ma. Within the first group are the Batopilas and Topia deposits...
