  7. Rockhounding- Amateur geology • have a hard, mottled, crystallinelook. Rock (geology) : Igneousrocks Plutonic Hypabyssal Extrusive(volcanic) gabbro syenite granite porphyry aplite pegmatite lamprophyre kimberlite picrite basalt andesite basalt melaphyre trachyte phonolite

  8. Rock (geology) : metamorphicrocks • Metamorphismmakesallrocks more tough and crystalline, but they are • changed in twodifferentways : Contactmetamorphism – rock isscorched by theheatofanigneousintrusion. Thisturnssandstoneintoquartzite, limestoneintomarbleand mudstone and shaleintohornfels. (…amongothersinclude : porcellanite, contact slate,…) Dynamic metamorphism - tectonicbreccia, mylonite Shock metamorphism – fulgurite, carbonite, porcellanite Regional metamorphism - rocks are crushedbeneathmountains by themovingplatesoftheEarth´ssurface. Thisturnsmudstone and shaleto slate,then to schistand then to gneiss as itissqueezedharder and harder.

  10. Sedimentary rocks Rock (geology) : What are sedimentaryrocks? Sedimentary rocks are formed by the accumulation of sediments. There are threebasic types of sedimentary rocks: 1) clastic sedimentary rocks -breccia, conglomerate, sandstone and shale…. 2) chemical sedimentary rocks - rock salt and some limestones…. 3) organic sedimentary rocks - coal and some limestones…….
