Describe the geosyncline model by Kober?

The geosyncline model postulated by German geologist Leopold Kober in 1921 is summarized below:
It should be mentioned that Kober, unlike one of his contemporaries Suess who focused the attention to tectonic forces, believed that geosynclines are the extensive elongated depositional troughs, which are very long in the process of sinking through earth’s crust as extended periods of geological time are concerned. They are bordered by comparably stable continental crust blocks. They are bounded by relatively stable continental lithosphere domains.
Thick sequences of sediments eroded from adjacent land areas are formed as the geosyncline progressively deepens. The greatest thickness of sediment is deposited in the geosynclinical region reaching its central part.
Finally, the load of the overlying sedimentary rocks precipitates the geosyncline down into the asthenosphere (the plastic layer beneath the earth’s crust). This begins the mountain making processes by folding and faulting of the subsequent layers of sedimentary rocks.
General subsidence creates a condition favorable for the accumulation of further, superimposed layers of sediment on deformed strata. Therefore, such cycles as sedimentation subsidence and deformation can cover hundreds of millions of years.
Finally, if ground conditions are suitable, the geosyncline might be squeezed, folded, and uplifted in the mountainous belt. These latter ones are part of continental crust which was initially evolved from seabed sediments. The first ones can also be at deep rock that has been eroded.
Kober regarded the Geosyncline idea as an explanation for sedimentary and tectonic history of many mountain systems and plates. Information about his contributor may be reported in historical context of the early twentieth century geology preceding the theory of plates.
Thus, Kober’s geosyncline model was long trending basins wherein very thick marine sediments had prograded and these were afterward folded and uplifted into mountain chains through subsidence and crust shortening processes spanning large periods of time.
