• LINK#Rock Identification Tables
   Identify 43 of the most common rock types: igneous, sedimentary and metamorphic.

   

  Identify almost any rock type you’re likely to find.

  • rock identification
  • igneous rocks
  • sedimentary rocks
  • metamorphic rocks

  Start by getting an idea of your basic rock class—igneous, sedimentary or metamorphic. Next observe the rock’s texture—its grain size and overall pattern—conduct a basic hardness test, and identify the minerals that compose it as well as you can. With that information, you can consult the table for the appropriate rock class. Detailed instructions are beneath the tables.Identification of Igneous RocksGrain SizeUsual ColorOtherCompositionRock Typefinedarkglassy appearancelava glassObsidianfinelightmany small bubbleslava froth from sticky lavaPumicefinedarkmany large bubbleslava froth from fluid lavaScoriafine or mixedlightcontains quartzhigh-silica lavaFelsitefine or mixedmediumbetween felsite and basaltmedium-silica lavaAndesitefine or mixeddarkhas no quartzlow-silica lavaBasaltmixedany colorlarge grains in fine-grained matrixlarge grains of feldspar, quartz, pyroxene or olivinePorphyrycoarselightwide range of color and grain sizefeldspar and quartz with minor mica, amphibole or pyroxeneGranitecoarselightlike granite but without quartzfeldspar with minor mica, amphibole or pyroxeneSyenitecoarselight to mediumlittle or no alkali feldsparplagioclase and quartz with dark mineralsTonalitecoarsemedium to darklittle or no quartzlow-calcium plagioclase and dark mineralsDioritecoarsemedium to darkno quartz; may haveolivinehigh-calcium plagioclase and dark mineralsGabbrocoarsedarkdense; always hasolivineolivine with amphibole and/or pyroxenePeridotitecoarsedarkdensemostly pyroxene with olivine and amphibolePyroxenitecoarsegreendenseat least 90% olivineDunitevery coarseany colorusually in small intrusive bodiestypically graniticPegmatite

• LINKUrban Ski Slope to Raise Profile of Europe's Waste-to-Energy Drive
  Copenhagen, with a waterfront already famous for bike lanes, pedestrian walkways, and offshore wind turbines, is adding another clean energy feature to its urban landscape: a ski resort.

  Perhaps the man-made slope will never rival the summits of Sweden or the Alps, where residents of Denmark’s capital city typically travel to ski. But it will draw attention to Copenhagen’s world-leading effort to cut fossil energy and waste. The ski slope will rest atop a $389 million (500 million euro), 60-megawatt power station fueled entirely by the city’s garbage. (See related: "Quiz: What You Don’t Know About Electricity.")

  The Amager Bakke incinerator, now under construction, will contribute to Copenhagen’s ambitious goal of becoming carbon-neutral by 2025. When finished in 2017, it will produce heat for 160,000 households and electricity for 62,500 residences. It is perhaps the flashiest example yet of Europe’s effort to deploy cutting-edge waste-to-energy technology in the effort to cut greenhouse gas emissions. While some critics in Europe’s green movement question the environmental benefits, and cost also can be an obstacle, cities like Copenhagen are convinced that producing megawatts is better than piling trash in landfills. (See related story: "On Mount Everest, Seeking Biogas Energy in a Mountain of Waste.")

  A man-made ski slope now being built on Copenhagen’s waterfront, as pictured in this illustration, will add a new clean energy feature to the Denmark capital’s skyline. The skiers, as pictured below, will schuss atop a high-efficiency waste-to-energy plant.
