Question

give an example of sills​

Answer 1

1. Such sills are known as transgressive, examples include the Whin Sill and sills within the Karoo basin. The geometry of large sill complexes in sedimentary basins has become clearer with the availability of 3D seismic reflection data

Answer 2

In geology, a sill is a tabular layer intervention that has imposed among older strata of sedimentary stone, areas of volcanic lava or tuff, or even adjacent the administration of foliation in metamorphic rock. The word sill is compatible with a concordant interfering sheet. The geometry of great sill associations in sedimentary sinks has become more apparent with the availability of 3D seismic concentration of data.
