Louis Caryl Graton
Louis Caryl Graton (1880–1970), American geologist, chemist and educator, began his career in 1900 as assayer for Ledyard Gold Mines Ltd., near Rockdale, Ontario. He moved on to Canadian Goldfields Ltd. later in 1900, then entered McGill University as a graduate student, studying many of the famous mines of Ontario and Quebec. He continued his studies at Cornell University in 1902–1903. In 1903, Graton was hired by Waldemar Lindgren of the US Geological Survey to assist Lindgren's restudy of the Cripple Creek, Colorado goldfields. This began an association that lasted until Lindgren's death in 1939. While at the USGS, he studied ore deposits in the southern Appalachians, New Mexico and California. In 1909, Graton was appointed assistant professor of mining geology at Harvard; he advanced to full professor in 1912, a position he would hold for 37 years. Graton made important contributions in applying the science of geology to the practical job of finding ore. He was notably ...

Harvard University
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees. Harvard has three main campuses: the Cambridge campus centered on Harvard Yard; an adjoining campus immediately across Charles River in the Allston neighborhood of Boston; and the medical campus in Boston's Longwood Medical Area. Harvard's endowment is valued at $50.9 billion, making it the wealthiest academic institution in the world. Endowment inco ...

1970 Deaths
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 '' Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar.

Bibliography
Bibliography (from and ), as a discipline, is traditionally the academic study of books as physical, cultural objects; in this sense, it is also known as bibliology (from ). English author and bibliographer John Carter describes ''bibliography'' as a word having two senses: one, a list of books for further study or of works consulted by an author (or enumerative bibliography); the other one, applicable for collectors, is "the study of books as physical objects" and "the systematic description of books as objects" (or descriptive bibliography). Etymology The word was used by Greek writers in the first three centuries CE to mean the copying of books by hand. In the 12th century, the word started being used for "the intellectual activity of composing books." The 17th century then saw the emergence of the modern meaning, that of description of books. Currently, the field of bibliography has expanded to include studies that consider the book as a material object. Bibliography, in ...

The R.A.F. Penrose Gold Medal was established in 1923 and is awarded by the Society of Economic Geologists (SEG) to recognize a full career in the performance of "unusually original work in the earth sciences". The medal was donated by American geologist and founding President of the SEG Richard A.F. Penrose Jr. At the time of its donation, Penrose was explicit in his desire that the medal be awarded for achievements in pure geological science, rather than in the application of science to the discovery of mineral deposits. Recipients SourceSEG See also * List of geology awards * Prizes named after people A prize is an award to be given to a person or a group of people (such as sporting teams and organizations) to recognize and reward their actions and achievements.

Society Of Economic Geologists
The Society of Economic Geologists (SEG) is a scientific organization that promotes the study of geology as it relates to mining, mineral exploration, mineral resource classification and mineral extraction. The society's Publication Board publishes the scientific journal ''Economic Geology''. The society serves 7,000+ members worldwide who are committed to advancing the science and the discovery of mineral resources through research, publications, courses, and field trips. History SEG began in 1919 with a group of Geological Society of America (GSA) with an interest in economic geology. December 28, 1920, 60 distinguished professionals met and established the organization. Notable economic geologists * Pavel Pavlovich Goudkoff (Gudkov) (1921).

Economic Geology
Economic geology is concerned with earth materials that can be used for economic and/or industrial purposes. These materials include precious and base metals, nonmetallic minerals and construction-grade stone. Economic geology is a subdiscipline of the geosciences; according to Lindgren (1933) it is “the application of geology”. Today, it may be called the scientific study of the Earth's sources of mineral raw materials and the practical application of the acquired knowledge. The term commonly refers to metallic mineral deposits and mineral resources. The techniques employed by other earth science disciplines (such as geochemistry, mineralogy, geophysics, petrology, paleontology and structural geology) might all be used to understand, describe, and exploit an ore deposit. Economic geology is studied and practiced by geologists. Economic geology may be of interest to other professions such as engineers, environmental scientists, and conservationists because of the far-reachi ...
