This is a directory devoted to undergraduate research in geology at private and public colleges and universities of the United States. It has been compiled from the responses to a questionnaire sent in late 1987 to the geology or earth science departments of 375 institutions. These departments were selected on the basis of the following criteria: (1) departments offering Bachelors and Masters in geoscience degrees only--no Ph.D.-granting departments included (departmental focus must be on undergraduates); and (2) departments with a record of undergraduate research participation or the interest in developing such a program. Data from 133 departments are contained in this book. The directory provides information about department size and composition (faculty, staff, and students), facilities (building space, library, and equipment), and funding over the last four years. A section on field course requirement and participation has been included. Faculty profiles for each department contain research interests, grant support, and a bibliography of refereed publications over the previous five-year period. The names of student co-authors of published work are indicated. Indices of institutions and faculty are provided. A ranking of the baccalaureate origins of doctorate recipients in the earth sciences is appended. (YP)
