求翻译：由于构造活动都集中在盆地边缘，而盆地内部则没有大的褶皱和断裂发育，盆地内部基本保持整体的均衡沉降，盆地周边的构造活动，则为盆地内部的沉积作用提供物源。是什么意思？

Tectonic activity is concentrated in the basin edge of the basin, there are no major folds and faults developed, the basin remained within the overall equilibrium sedimentation basin surrounding tectonic activity, compared with the deposition of the basin within the provenance.

As construction activities are focused on the basin edges, and there are no large basin is within the wrinkles and broken, basin development remained within the overall balance of the settlement, basin structure around the basin, and activities within the source material for deposition.

Due to tectonic activity is concentrated at the edge of the basin, basin interior is no major folds and faults, of balance settlement remained within the basin as a whole, around the basin of tectonic activity, the basin of deposition within the provided source.

Because the structure activity all concentrates in the basin edge, but the basin interior does not have the big fold and the break growth, the basin internal basic maintenance whole balanced subsidence, the basin peripheral structure activity, then for basin internal deposition tender source.
