Abstract

A Penrose Conference on The Relationship between Linear Volcanic Chains, Melting Spots, and Plate Motions will be convened by Marvin A. Lanphere and G. Brent Dalrymple, May 19–24, 1974, at the Asilomar Conference Grounds, Pacific Grove, on the Monterey Peninsula, California.

The purpose of the conference is to examine in detail the relationships between major linear volcanic chains, their proposed melting spots, and plate motions and t o evaluate the validity of the melting spot hypothesis. Primary emphasis will be on the petrology, geochemistry, and geochronology of volcanic chains, the geophysical characteristics of proposed melting spots, melting spot models a n d the adequacy of theoretical mechanisms to account for the observed geologic, geochemical, and geophysical features of the chains, and the relations between relative plate motions deduced from linear volcanic chains and from magnetic anomaly patterns at spreading ridges. An important goal of the conference will be to promote interaction between earth scientists concerned mainly with the relationship of plate geometry to melting spot mechanisms, and those concerned primarily with detailed field, petrologic, and geochemical studies.
