28 Petrologists

Charles Eugene Barrois was a French geologist and palaeontologist.

Friedrich Johann Karl Becke was an Austrian mineralogist and petrographer.

Norman Levi Bowen FRS(June 21, 1887 – September 11, 1956) was a Canadian geologist. Bowen "revolutionized experimental petrology and our understanding of mineral crystallization". Beginning geology students are familiar with Bowen's reaction series depicting how different minerals crystallize under varying pressures and temperatures."

Christian Leopold von Buch, usually cited as Leopold von Buch, was a German geologist and paleontologist born in Stolpe an der Oder and is remembered as one of the most important contributors to geology in the first half of the nineteenth century. His scientific interest was devoted to a broad spectrum of geological topics: volcanism, petrology, fossils, stratigraphy and mountain formation. His most remembered accomplishment is the scientific definition of the Jurassic system.

Charles Whitman Cross was an American geologist. He was educated at Amherst College, the University of Göttingen, and Leipzig University. A petrologist, much of his field work concerned rocks in Colorado. He and three other geologists proposed the CIPW norm that is still used in normative mineralogy. He was also active in scientific societies and institutions.

Harry von Eckermann (1886–1969) was a Swedish industrialist, mineralogist and geologist. His studies were centered around anorogenic alkaline igneous rocks occurring in the Baltic Shield. Following this line he studied the Alnö Complex, Norra Kärr Alkaline Complex and various Rapakivi granites.

Charles Henry Emeleus was a British igneous petrologist. He specialized in the Tertiary volcanic rocks of Britain and Greenland.

Pentti Eelis Eskola was a Finnish geologist who developed the concept of metamorphic facies. He won the Wollaston Medal in 1958, the Vetlesen Prize in 1964, and was given a state funeral upon his death. The mineral eskolaite is named in his honor.

Ferdinand André Fouqué was a French geologist and petrologist.

Sven Gavelin was Swedish geologist active at Stockholms högskola and the Geological Survey of Sweden. As a geologist he worked chiefly with Precambrian events and rocks. Sven Gavelin made significant contributions to the understanding of the ore deposits of Västerbotten. Some other topics he investigated include the Almesåkra Group,

Otto Hahn was a German petrologist, geologist, lawyer and author. His father was Johann Franz Gottlieb Hahn. His great-grandfather was Christian Tobias Hahn, who was the half-brother of Philipp Matthäus Hahn.

Alfred Harker FRS was an English geologist who specialised in petrology and interpretive petrography. He worked for the Geological Survey of Scotland and conducted extensive surveying and geological studies of western Scotland and the Isle of Skye. He and other British geologists pioneered the use of thin sections and the petrographic microscope in interpretive petrology.

Timothy John Barrington Holland is a petrologist and reader in the Department of Earth Sciences at the University of Cambridge.

M. Qasim Jan is a geologist and research scientist from Pakistan. He has been the vice-chancellor of three Pakistani universities. His research has been in geology, mineralogy, petrology, geochemistry, and tectonics. He has authored or edited a dozen books, and has published numerous papers on geology and tectonics of the North-West Himalayas. Presently, he is Professor Emeritus at the National Centre of Excellence in Geology, University of Peshawar. Jan is also currently the Secretary General of the Pakistan Academy of Sciences, and of the Association of the Academies of Sciences in Asia. He is also a fellow of the Academy of Sciences for the Developing World (TWAS).

Hisashi Kuno was professor at the Institute of Geology, University of Tokyo. He was first son of Kamenosuke Kuno and Tome Kuno.

Antoine François Alfred Lacroix was a French mineralogist and geologist. He was born in Mâcon, Saône-et-Loire.

Henry Carvill Lewis was an American geologist and mineralogist.

Karl August Lossen was a German petrologist and geologist.

Paul Niggli was a Swiss crystallographer who was a leader in the field of X-ray crystallography.

Walther Penck was a geologist and geomorphologist known for his theories on landscape evolution. Penck is noted for criticizing key elements of the Davisian cycle of erosion, concluding that the process of uplift and denudation occur simultaneously, at gradual and continuous rates. Penck's idea of parallel slope retreat led to revisions of Davis's cycle of erosion.

Jakob Johannes Sederholm was a Finnish petrologist most associated with his studies of migmatites.

Charles Henry Smyth Jr. was an American geologist. Born to a prominent family in Upstate New York, he studied geology at Columbia University before becoming a professor of geology at Hamilton College and Princeton University. At Princeton he strengthened the Department of Geology's graduate program.

Alférez de Navío José María Sobral was an Argentine military scientist, Navy Sub-Lieutenant who rose to prominence by participating in the Swedish Antarctic Expedition (1901–1904) becoming the first Argentine to overwinter in Antarctica. Later he pursued studies at Uppsala University becoming the first Argentine to obtain a geology degree. Sobral worked briefly as ambassador to Norway in 1930 before returning to Argentina to work at YPF.

Raimon Tolosana-Delgado is currently working at Helmholtz-Institut Freiberg für Ressourcentechnologie, Germany. Raimon received the Felix Chayes Prize in 2013, and the Andrei Borisovich Vistelius Research Award in 2007, from the International Association for Mathematical Geosciences. He is an elected Executive Vice President of the International Association for Mathematical Geosciences

Johan Herman Lie Vogt was a Norwegian geologist and petrologist. Vogt was a professor at the University of Oslo and at the Norwegian Institute of Technology.

Ernst Heinrich Oskar Kasimir Weinschenk was a German mineralogist and petrologist.

Carl Ernst Arthur Wichmann was a German geologist and mineralogist. He was professor in geology at Utrecht University from 1879 to 1921, where he founded the geological institute. His daughter was the jurist and anarchist-socialist Clara Wichmann, his son the artist and fascist Erich Wichmann.

Prof Ferdinand Zirkel FRS(For) HFRSE was a German geologist and petrographer.
