| Once a prospective tectonic setting is identified, we can determine where to focus exploration within that setting. This can be done most effectively by defining the boundaries and internal structural character of the different structural domains within the tectonic setting. | | Once a prospective tectonic setting is identified, we can determine where to focus exploration within that setting.

− | Among different tectonic settings, the number and complexity of the structural domains can vary significantly. For example, the number and character of the structural domains defined in a basin forming in the cratonic interior in a relatively quiet but long-lived tectonic setting contrast significantly to those defined in a short-lived but intense rifting event. | + | Among different tectonic settings, the number and complexity of the structural domains can vary significantly.
