Geological Observations On Volcanic Islands

Geological Observations On Volcanic Islands is a scientific book written by the renowned naturalist Charles Darwin. The book is a detailed account of Darwin's observations and findings during his five-year voyage on the HMS Beagle, particularly on the geology of volcanic islands. The book is divided into two parts, with the first part focusing on the geology of the Galapagos Islands, while the second part covers the geology of other volcanic islands, including St. Helena, Ascension Island, and the Cape Verde Islands. The book is an important contribution to the field of geology and natural history, as Darwin's observations and analysis helped to establish the theory of plate tectonics and provide insight into the formation and evolution of volcanic islands. Darwin's meticulous observations and detailed descriptions of the geological features of the islands, such as the lava flows, volcanic craters, and geological formations, provide an invaluable resource for scientists and researchers studying the geology of volcanic islands.Geological Observations On Volcanic Islands is a significant work in the history of science, as it showcases Darwin's keen observational skills and scientific methodology, which would later inform his groundbreaking work on evolution. The book is a must-read for anyone interested in geology, natural history, or the life and work of Charles Darwin.The overlying basaltic lava is in some parts extremely vesicular, in others little so; it is of a black colour, but sometimes contains crystals of glassy feldspar, and seldom much olivine. These streams appear to have possessed singularly little fluidity; their side walls and lower ends being very steep, and even as much as between twenty and thirty feet in height. Their surface is extraordinarily rugged, and from a short distance appears as if studded with small craters.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
