pennsylvanian period

الإنجليزية - الإنجليزية

تعريف pennsylvanian period في الإنجليزية الإنجليزية القاموس.

In North America, the interval of geologic time roughly equivalent to what is internationally designated the Late Carboniferous Period (323-290 million years ago). Because the rocks that originated during this span of time are widespread in the state of Pennsylvania, some U.S. geologists favour the term over Late Carboniferous Period, which was first adopted in Europe
