The Pre-Cambrian Era, to correlate them. A few interesting fossils have been found in the younger Pre-Cambrian rocks, but it remains generally true to say that there are none of stratigraphical value. Isotopic dating is therefore of great value and most correlation of Pre-Cambrian rocks is based upon it, especially as t作者: 強(qiáng)制性 時間: 2025-3-22 11:43
The Lower Palaeozoic Geosyncline,folding movements, into a folded-mountain chain. A geosyncline (Fig. 5) can be defined as an elongated downwarping of the crust of the earth, forming a deep trough in which a great thickness of sediments accumulates. This definition needs to be somewhat enlarged. First the downwarp is occupied by th作者: Communicate 時間: 2025-3-22 16:52
The Caledonian Mountain-building,he Lower Palaeozoic era (Fig. 7), these movements being named the Caledonian Orogenesis; one can hence speak of Caledonian structures having been imposed on the rocks and of the Caledonian mountains having been produced.

The Alpine Mountain-building and the Later Tertiary, along the line of the Mediterranean and the Alps, occupied by the geosynclinal sea known to geologists as Tethys. This geosyncline underwent several preliminary folding movements, culminating in a main phase in the mid- or late Oligocene when the Alpine fold mountains were formed.作者: Benign 時間: 2025-3-24 05:34 作者: aphasia 時間: 2025-3-24 08:23 作者: Ballad 時間: 2025-3-24 12:29

Thirdly, an essential part of the definition is that the geosynclinal sediments are later compressed and folded by the movement together of the sides of the downwarp, and so come to form fold-mountains.作者: 語源學(xué) 時間: 2025-3-26 15:25 作者: Glucose 時間: 2025-3-26 19:04
