The exploitation of rock-bound resources required a level of understanding of rock composition and structure that remains impressive today. The mining of metals, the extraction of building stone, the engineering of waterways, developed over the centuries. Today, geological materials have become utterly pervasive within our lives. ‘Geology for resources’ considers how geologists seek out these resources from within the crust of our planet, focusing on fossilized hydrocarbons used as energy resources (coal, oil, and gas); the metal extraction process from metal ores; industrial mineralogy; phosphates, essential nutrients in agriculture; and hydrogeology, the study of underground water resources.","PeriodicalId":206455,"journal":{"name":"Geology: A Very Short Introduction","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115376193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geology is a science encompassing virtually all the other sciences—chemistry, physics, biology, geography, oceanography, and many others—and involves or impinges upon many of the humanities and arts, and day-to-day life.

It also looks at the ways that geological time has been subdivided using biostratigraphy (the tracking of species’ evolution through fossils) and tracing chemical changes in the rocks. Earth’s evolution has included regular and gradual influences, with episodes of sudden massive change from more or less random events.","PeriodicalId":206455,"journal":{"name":"Geology: A Very Short Introduction","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114601728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
