Study of the historical geology, volcanology, and sedimentation of secondary pyroclastic eruptions on Oahu.

Pyroclastic Rocks is the first modern comprehensive treatment of what they are and how they were formed. The subject is discussed against a background of plate tectonics theory and modern advances in volcanology, sedimentology and igneous petrology. The book provides a thorough discussion of magmatic volatiles and pyroclastic processes as well as magma-water interactions. Most of the book is concerned with the wide spectrum of pyroclastic rocks formed on land and under water and by fallout and various flowage mechanisms. Diagenetic processes by which pyroclastic particles are transformed into rocks are discussed in detail. The stratigraphic and tectonic importance of pyroclastic rocks are illustrated using selected case histories. This uniquely integrated account of pyroclastic processes, particles and rocks will prove a valuable aid in reconstructing dynamic aspects of earth evolution as well as predicting future volcanic hazards; understanding sedimentary basins containing petroleum and gas deposits; locating ore deposits in volcanic complexes and heat sources in geothermal prospecting; and facilitating stratigraphic analysis in complex volcanic terrains.

This publication consist of two parts exclusively covering the Island of Oahu, definted by the Koolau and Waianae ranges. Part 1 (1-198) is concerned with topics related to geology and part 2 (199-467) is concerned with topics related to ground water resources. The geology pertains to the Waianae volcanic series, Kailua volcanic series, Koolau volcanic series and the Honolulu volcanic series. The study covers climate generated water, surface water, ground water, and access to these water sources.

Briefly mentions coral reefs in the areas of Wailupe, Waialae, Sand Island in Honolulu Harbor, the Ala Wai, Waikiki, Pearl Harbor, Kapahulu, Kaimuki, Moanalua, Waianae, Kalihi, Kewalo, Barbers Point Lighthouse, and Black Point in Kahala.
