Geology continues its reign as the Journal Citation Reports’ #1 ranked
geology journal for the twelfth year in a row. According to Clarivate
Analytics (formally Thomson Reuters), it had a 2019 impact factor of
5.073 and a five-year impact factor of 5.451.

The Geological Society of America Bulletin’s impact factor was 4.039,
with a five-year impact factor of 4.45. GSA Bulletin ranks 19 among
multidisciplinary geoscience journals.
Both the impact factor and five-year impact factor soared for
Geosphere, reaching 2.811 and 2.741 respectively.

The impact factor for Lithosphere was 2.766, with a five-year impact
factor of 3.195.

While Clarivate Analytics does not produce impact factors for book
series, it indexes GSA’s Special Papers, Memoirs, and Reviews in
Engineering Geology in its Book Citation Index, which is part of the
Web of Science.
