What is "induan"

The Induan is, in the geologic timescale, the first age of the Early Triassic epoch or the lowest stage of the Lower Triassic series. It spans the time between Ma and Ma (million years ago). It is preceded by the Changhsingian and is followed by the Olenekian.

The Induan is roughly coeval with the regional Feixianguanian stage of China.
