For the basic sedimentary rock classification you can use the table at the top (go to enlarged clickable version), or use the key (also linked in the box above left), or go to the alphabetical listing to directly study individual sedimentary rocks An explanation of the theory behind the basic classification is below

To use our Sedimentary Rock Identification Flow Chart, it will be easiest if you print out your own copy first The flow chart moves from left to right, following the arrows Step 1: Select a Sedimentary rock - Choose a sedimentary rock that you want and place it on the “Sedimentary Rock to Identify” block
Rock Name: Clastic Coarse Grains >2 mm: Any rock type (quartz, chert, or quartzite most common) Rounded clasts : Conglomerate: Angular clasts: Breccia: Fine Grains 1/16 to 2 mm Can be seen w/ naked eye: Quartz with minor accessory minerals: White, tan, brown; sandpapery feel: Quartz Sandstone: S A N D S T O N E
Sediment turns into sedimentary rock by some combination of burial beneath more sediment, compaction into a smaller volume (due to being compressed by the weight of more sediment piled on top), and cementation by new mineral growth precipitating between the sediment grains This is commonly summarized as "burial, compaction, and cementation"

To identify a rock, think like a geologist and examine its physical characteristics for clu The following tips and tables contain characteristics that will help you identify the most common rocks on earth Rock Identification Tips First, decide whether your rock is igneous, sedimentary or metamorphic

Sedimentary Rock Detrital Clastic -- Mud-sized grains --NOT white -- doesn't break in layers Mudstone 47 99 Igneous Rock Aphanitic -- Porphyritic -- Phenocrysts are K-Feldspar and Quartz (therefore Felsic) K-Feldspar & Quartz Rhyolite Porphyry To identify (name) igneous rocks, you determine two things about the rock: composition and texture

The Sedimentary Rock Textures Chart on the following illustrates the major sedimentary rock textur Below, we define a few of the terms geologists use to describe these textur ♦ Clastic texture: grains or clasts do not interlock but rather are piled together and cemented Boundaries of .
Pass out one rock at a time to each group and allot 5 minutes to test, discuss and decide on its rock name After 5 minutes, ask questions from the flow chart to guide students to the correct rock name and chart the results Students record rock characteristics in the data table
Sedimentary rocks are classified in large part, by the size of the particles of which it is made The most common scheme for classifying sediment size is the Wentworth Scale There are specific size values assigned to the scale For example, a coarse sand is defined as a grain of rock whose diameter is between 1mm and 1/2mm
However, no one chart ever identifies more than 42 rocks and most identify 12-20 in one chart So if you're using a decision chart and you're having trouble getting your rock to fit, be aware that there are many more rock possibilities out there and you may need to move to another, usually more complex, chart to finalize your identification
Metamorphic rocks form from pre-existing rocks ("parent rocks") due to changes in either temperature, pressure, or volatiles within the earth, often by a combination of all three Volatiles are those chemical substances, including water and carbon dioxide, that easily turn into gas or fluid and are mobile enough to move in and out of solid rock .
Evaporites - chemical sedimentary rocks that form through the evaporation of water; usually found in dry lake beds (playas) Rock salt, rock gypsum, are two exampl Coal - organic sedimentary rock composed of the remains of plant material Various grades of coal include peat, lignite, bituminous coal, and anthracite coal
Sedimentary Rock Classification Chart Grain size/ Class texture Gravel (grains >2 mm) , metallic or resinous appearance Properties and Distinguishing Features Rounded rock and rmneral fragments, usually a finer matrix Angular rock and mineral fragments, usually in a finer sand , Sedimentary Rock Name Conglomerate Breccia Pure sandstone .
into a sedimentary rock Sedimentary rocks like sandstone, shale and limestone differ from other rocks in that they: 1 Are formed from layers of sediment built up over many years 2 Are grains of sediment cemented together by various minerals 3 May contain fossils - remains of plants and animals that were caught up in the sediment 4
2 Go the three rock textures pages (see links above) to compare the pictures with your sample 3 Determine if your rock is igneous, sedimentary, or metamorphic by observing and describing its properti 4 On a pace paper, draw a table like the one outlined after the flow chart, explaining on the side how the rock formed
Mixed metamorphic and igneous rock Feldspar, quartz, mica, ferromagnesian minerals Alternating layers of felsic igneous rock and mafic gneiss; the last metamorphic grade prior to complete melting
Sedimentary rock - Sedimentary rock - Grain size: Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration
