Sedimentary Rocks Sedimentary Rocks Sedimentary rocks form in of ways: Clastic Sedimentary Rocks- made of pieces and grains of other rocks Material such as sand or mud -usually deposited in water Conglomerate sandstone Sedimentary Rocks Chemical Sedimentary Rocks- deposited in water from chemicals and minerals in the water -limestone is deposited in water from calcite Sedimentary Rocks • Organic sedimentary rocks- made up of remains of plants or animals – Chalk is made from tiny shells – Coal is made from ancient plants Other sedimentary Features Fossils- can be very common in sedimentary rocks Nodules- (concretions) are ball-shaped rocks formed around a hard center object such as a sand grain Geodes- hollowed out nodules with crystals filling the center area Crystals are usually quartz Rock Name Sandstone Sedimentary Rocks Formation clastic Composition Other Features/Color sand grains rust color(iron) Rock Name Shale Sedimentary Rocks Formation clastic Composition Other Features/Color mud “mud stone”, layers Sedimentary Rocks Rock Name Formation Composition Other features/color Conglomerate clastic rocks,cements natural cement Sedimentary Rocks Rock Name Formation Composition Other features/color Coal organic ancient plants black, carbon Sedimentary Rocks Rock name formation Limestone chemical composition other features/color calcite caves Sedimentary Rocks Rock name formation Nodule clastic composition other features/color sand grains desert rose Sedimentary Rocks Rock name formation Geode clastic composition other features/color quartz crystals hollow “earth stone” Sedimentary rocks Rock name formation composition other features/color Agate clastic quartz “melted quartz” Sedimentary Rocks Rock Type formation Jasper clastic composition other features/color quartz reddish brown “Jasper” Sedimentary Rocks Rock Type formation 10 Chert clastic composition other features/color quartz brown, arrowheads Quiz: Sedimentary Rocks What you should know - You should be able to identify the 10 sedimentary rocks - You should know which are clastic, chemical, and organic - You should know how clastic, chemical, and organic rocks form - What is a nodule?
