This book focuses on the highly touristed, but surprisingly under-researched Lesser Antilles region. After offering a brief overview of the region’s geologic and tectonic history, as well as its basic climatology, subsequent chapters then... more
Roughly 60% of the Earth's outer surface is composed of oceanic crust formed by volcanic processes at mid-ocean ridges. Although only a small fraction of this vast volcanic terrain has been visually surveyed or sampled, the available... more
The emergence of intelligence is a relatively recent phenomena throughout the cosmos. The total number of habitable extraterrestrial planets within the Milky Way capable of supporting advanced, intelligent life within the next 500 Myr is... more
The Pinnacles Volcanic Formation and the Neenach Volcanic Formation originated from a series of common eruptive centers during the early Miocene. The once contiguous units were subsequently split and separated 314 km from each other by... more

Debate over the question of whether basement rocks folded or faulted during the Laramide orogeny in the Wyoming province of the Rocky Mountain foreland has raged for many years. Proponentsbl one view or the olher have drawn support for... more
Sheet intrusions supply magma to almost all eruptions. Mechanically, the erupting sheets are primarily extension fractures and of two main geometric types: dikes and inclined (cone) sheets. Regional dikes are mostly subvertical, many... more

Within the framework of the International Continental Drilling Program (ICDP) we propose a comprehensive initiative to drill the continental crust bordering modern and ancient convergent and collisional plate boundaries. These zones host... more
Based on the earlier research, metamorphic rock in Bayah Complex and in its surrounding area are consist of various types of rock with different degrees in metamorphism (low to high grade metamorphism) and their protolith as well. The... more
In his seminal essay “Towards a Critical Regionalism,” the architectural historian Kenneth Frampton argued that the ontological condition of architecture is found in the poetic expression of a structure’s constructional logic. This stance... more
