The folds of the strata –anticlines and synclines with all variations and combinations you may think- change enormously in scale, from folds of kilometric length whose interpretation is often difficult in the overgrown or overly artificialized landscape, to microfolds of metric or centimetric size that can be seen closely in full. Sometimes, not always, the … Read more
