Volcanism and tectonism in the Columbia River Flood-Basalt Province.
It is believed that the NW-SE orientation is largely a result of compressional tectonism (mountain building processes) and the NE-SW orientation is largely a result of subsequent tensional movement (faulting, shearing).
But the book also looks at the effects of plate tectonics--earthquakes, tsunamis, and volcanism--on contemporary life (and death) along the Pacific margin of South America, a significant chunk of what is often termed the "Ring of Fire." The third interwoven component is that of author Rob Wesson's geophysical researches into tectonism in southern South America, plus his personal retracing of Darwin's inland excursions.

Potwar sub basin is considered to have a significant hydrocarbon potential among all basins due to variation in sedimentary deposition and salt tectonism. The conventional exploration methods applied, particularly for Paleocene, Eocene and Miocene deposits have been tested by many companies over the past decades.
Geologists intentionally employ the bland word "resurfacing" to avoid attributing a cause, because we don't know if the resurfacing was caused by volcanism, impacts, tectonism, some combination, or none of the above.

Interplay of oceanographic and paleoclimate events with tectonism during middle to late Miocene sedimentation across the southwestern USA.
Geologists and paleontologists from the US describe the geology and paleontology of Tule Springs Fossil Beds National Monument; the geography, stratigraphy, and paleontology of the Santa Ana Mountains; Neogene sedimentation, volcanism, and faulting in the eastern Coyote Mountains; arc magmatism, tectonism, and tempos in Mesozoic arc crust sections of the Peninsular and Transverse Ranges; late Cretaceous to early Neogene tectonic development of the southern Sierra Nevada region; and the geology of the Cemex Inc.
Unit 2 (U2) is very thick, over 1000 m, and is primarily composed of alluvial sandstone and medium- to thick-bedded, light gray to red, cobble-boulder conglomerate, which suggests that deposition occurred proximal to its source areas and may be related to tectonism during the Cenozoic Indo-Asian collision.
